Explore the relevant standards

EN 1149-3

The EN1149 standard relates to a number of performance requirements relating to antistatic clothing that suppresses static charge to prevent sparking which may lead to fire or explosion. EN1149-3 specifically relates to the test methods for the measurement of electrical charge decay.

Defining the EN1149 Certification

Each certification uses a standard picture or pictogram to allow for easy identification on labeling and tech or data sheets. The standard pictogram for EN1149 is a lightning bolt above the text EN 1149 and covered the requirements for clothing that can conduct electricity. This clothing, footwear included, created part of a completely grounded system to prevent sparks or static discharge.

This type of clothing is typically worn by professionals and companies who must adhere to ATEX guidelines. It should be noted that the clothing should not be worn in oxygen-rich environments and is not intended to provide protection against the risk of electric shock.

Variable Testing

Fabrics for clothing worn in explosion-hazard environments must be compliant to either EN1149-1 or EN1149-3 testing.

EN1149-1: Electrostatic Properties of Protective Clothing

The fabric is tested to release its electrostatic charge via conduction. The test is done to measure the surface resistance, which must be less than 5 x 1010 Ω. Note that electricity can be conducted through homogenous or heterogeneous materials. If the materials being tested are heterogeneous, then static charges must be release through a grid of conductive fibers (such as metal or carbon) with a max measurement of 10mm x 10mm.

EN1149-3: Electrostatic Properties of Protective Clothing

The fabric is tested to release its electrostatic charge into the air, not through conduction. This standard utilizes a test method that measures the amount of time it takes for a static electrical charge to completely dissipate. The electrostatic discharge of clothing is measured by t50% < 4 s or S > 0.2.

Additional Requirements Set in the EN1149-3 Standard

  • Any material carrying an electrical charge must be covered from the outside (such as metal buttons)
  • Non-conductive elements are permitted provided they are permanently attached and do not use removable elements (Velcro, metal or magnetic backings for badges, etc.)
  • Shoes that conduct electricity are required to meet compliance.
  • Garments must be designed in a way that outer material remains in contact with skin.

Notation on ATEX and EN 1149-3

ATEX is considered to be a guideline for businesses and industry, not a standard. The ATEX guidelines were developed for businesses or any industry where there is a notable risk for explosion. This includes companies working with dry dust grains, flour, chemicals. The guidelines include types of equipment, installation and handling of product, security but also includes recommendations and guidelines for personal protective equipment (PPE). Any clothing certified according to EN1149 standards is in compliance with the guidelines set forth by the ATEX model.

EN20471 / ANSI 107

The EN 20471 standard clearly defines the requirements for safety clothing and high visibility clothing used to improve visibility and emphasize the presence of the wearer in environments where visibility is an issue, or when the wearer is unable to fully concentrate on traffic in their immediate vicinity. It’s intention is to increase visibility in all light conditions, but hazardous situations in particular (such as at night, where visibility can be intensified with light).

Defining the EN 20471 Certification

Each certification uses a standard picture or pictogram to allow for easy identification on labeling and tech or data sheets. The standard pictogram for EN471 is a safety vest in proximity to two numbers – the X and Y values. The top X value indicates the class of the garment from 1 to 3, 3 being the most visible. The “Y” value indicates the intensity and retro-reflective performance of the reflective tape or material on the garment.

EN471 – Examining the X Value

High visibility clothing encompasses two things to improve visibility. Reflective tape or reflective material (night time) and fluorescent color (day time). The X value is derived from the number of square meters of reflective stripping within the garment and the number of square meters of fluorescent fabric.

MaterialClass 1Class 2Class 3
Fluorescent Material0,140,500,80
Reflective Material0,100,130,20
Combined Material0,20  

Class 1 – Offers the least protection and visibility and is not suitable for use on public highways. It’s is used in low traffic environments such as parking lots and general work sites where equipment traffic does not exceed 25mph.

Class 2 – Used in locations where proximity to traffic is much closer, with potential for traffic to exceed 25mph.

Class 3 – Highest visibility protection for utility workers, road crews and emergency personnel with high speed potential and the highest risk of injury.
(see article on safety garment classifications here) <- link to “safety garment classifications” article

EN 20471 – Examining the Y Value

The Y value of the standard is determined by the quality of the reflective strip in the safety garment, and the value is shown as either 1 or 2. A value of 2 is the highest reflective performance.

EN 20471 Standard Requirements

The fluorescent fabric must encircle the torso and include the sleeves and legs. The difference in surface area between the anterior and posterior of the garment may be up to 60%. Reflective stripping must be 50mm wide with a space of at least 50mm between the reflective strips. There are no standards for positions of reflective strips, trim or design.


TEN 343 is a certification standard used to clearly define the requirements and the methods of testing materials as well as the seams of clothing that are designed to protect the wearer from moisture; specifically, protection against rain and snow, mist and ground moisture. This standard is not intended to test the rain proofing of a completed garment, that standard falls under EN 14360. A complete rain proofing test is not part of the EN 343 standard.

Defining the EN343 Certification

Each certification uses a standard picture or pictogram to allow for easy identification on labeling and tech or data sheets. The standard pictogram for EN343 is an umbrella with water droplets placed in proximity to two numbers – the X and Y values. The “X” value of EN343 relates to the waterproofing of the material in question. The “Y” value indicates the permeability of the garment to water vapor in relation to respective breathability.

EN343 – Examining the X Value

The X value, as stated, defines the waterproofing of the material or garment. There are 3 classifications in this regard with 3 being the highest and most waterproof, and 1 being the lowest or least waterproof. To test, pressurized water is applied to the fabric or garment and the respective classification is chosen based on how much water the fabric can tolerate.

EN343 – Examining the Y Value

Breathability is important in fabric and like the X value, the Y value has 3 classifications for breathability. Class 1 is the lowest breathability and class 3 is the highest. Instructions for the fabric or garment often dictate the length of time the article can be worn, and wearing classifications beyond their limits is not recommended.

EN343 Auto-certification

This is one of the standards that fall within the range of auto-certification. A product or garment manufacturer is permitted to certify their own product line, and no subsequent testing from an outside institute, staff or facility is required. Auto-certification is permitted because the only risk to the wearer of the garment or product is that water would penetrate and they would get wet. Since moisture, in most cases, is not life-threatening, outside testing is not necessary. There are some exceptions however, such as when EN343 is applied in combination with other standards (such as a complete waterproof safety garment). In such cases, outside testing is likely to be assessed by another agency.

Notable Requirements

It should be noted that fabrics and garments must meet EN 340 requirements. Likewise the tear resistance and seam strength as well as the tensile strength must all be within specified tolerances. Lastly, clothing carrying the EN343 standard must be free of opening that could allow in water during normal use (such as detachable sleeves).


EN 469 covers the requirements for firefighters’ protective clothing or the turnout gear (kits) used and worn during structural firefighting where that gear is used to protect from fire and heat. The performance requirements for fire fighter clothing conforming to this standard will include:

• Flame spread (tested to ISO 15025)
• Convective heat (tested to EN 367)
• Radiant Heat (Tested to ISO 6942)
• Heat Resistance (tested to ISO 17493)
• Water Repellence
• Dimensional Stability
• Chemical Resistance

Defining the EN469 Standard

Each certification uses a standard picture or pictogram to allow for easy identification on labeling and tech or data sheets. The standard pictogram for EN 469 depicts a fire fighter spraying a flame.

Photometric requirements for retro-reflective materials are according to EN471 Table 5 (Level 2, 220 table) or Table 7 (combined performance materials, 65 table). The minimum amount of reflective material is 0.13 m2.

EN469 – Flame Spread

A test is performed on the material to check for limited flame spread. This includes after burn time, length of afterglow, formation of holes and for melting debris to exit the garment. This test is often performed on seams, wristlet material and additional secondary hardware.

EN469 – Heat Transfer (radiation)

This test measures the radiant heat transfer index of the textile or material being used by the fire fighter. The test includes measurement of the heat flux density as well the time it takes for the temperature to rise inside the garment.

EN469 Heat Transfer from Flame

This is a similar test to radiant heat transfer performed on the material to check the heat transfer index of textiles or material in direct contact with flame. Like radiant tests, this test includes measurement of the heat flux density as well as the time it takes for the temperature to rise within the garment.

EN469 Residual Strength

This is an overall measurement of the garment pre- and post treatment, primarily after exposure to radiant heat according to ISO 6942. This test measures heat flux density and the tensile strength in cross direction and machined direction.

EN469 Heat Resistance

This test measures overall heat resistance and the result of exposure to oven temperature for a set duration. Requirements must be met for ignition, melting, hole formation, dripping and shrinkage of the machine/cross.

EN469 Tensile and Tear Strength

After exposure, the tensile and tear strength of the garment is examining including the outer shell material of the garment and any primary seams.

Additional tests are performed on firefighting garments and material used within such as surface wetting tests, dimensional change, penetration of liquid chemicals, resistance to water penetration, water vapor resistance and overall visibility.

Visibility is an important test factor if the gear or material is fitted with retro-reflective and/or fluorescent elements. Those elements are required to meet the requirements of EN 471 table 5 or 7. This test measures the minimum area of reflective material as well as the minimum area of fluorescent material.

Reflective Material

Note that all reflective and high visibility materials are individual tested and must also pass the limited flame spread testing and heat resistance tests while meeting minimum values for retro-reflection post exposure to testing conditions.

ISO 14116

ISO 14116 is an international standard that is intended to specify the minimum performance requirements for limited flame spread properties of materials used in protective clothing. The overall purpose is to reduce the possibility of ignition in clothing which becomes a hazard to the wearer. PPE and other materials in compliance with ISO14116 are intended to offer worker protection only from brief contact and proximity to small flames – particular those with no notable or significant heat hazard.

Defining the ISO14116 Certification

Each certification uses a standard picture or pictogram to allow for easy identification on labeling and tech or data sheets. The standard pictogram for ISO14116 is a symbol of flame. The testing will produce a final index that is marked as “limited flame spread index/cleaning index”. The limited flame spread index listed will be the lowest value determined either before or after cleaning.

ISO14116 Testing Methods

Materials are testing using cleaning, aging, thermal performance and mechanical use. Cleaning takes place per the manufacturer’s instructions before each test on the basis of a standard procedure, including recommend wash settings and number of cycles. Age is considered, where performance tests take place after the maximum number of washes indicated by the manufacturer.

Thermal performance attempts to achieve limited flame spread by testing surface ignition before and after pretreatments. After application of test the material will receive a limited flame spread index.

For complete garments the mechanical performance is tested in accordance with ISO 13934 for tensile strength, tear resistance and seam strength.

On completion of testing, the material or garment is given one of the 3 limited flame spread index ratings.

ISO14116 Limited Flame Spread Index 1

To meet limited flame spread index 1, the material must give off no flaming debris. There must be no afterglow spreading from the carbonized area to the undamaged area once exposure to flame ceases. Most importantly, no spreading of the flame occurs. With limited flame spread index 1 classification, it is possible for a hole to form.

ISO14116 Limited Flame Spread Index 2

To meet limited flame spread index 1, the material can give off no flaming debris. There must be no afterglow spreading from the carbonized area to the undamaged area once exposure to flame ceases. There is zero hole formation in the material and zero spreading of flame across the material.

ISO14116 Limited Flame Spread Index 3

With limited flame spread index 3 there is no spreading of the flame across the material. No notable afterglow occurs and no flaming debris are present. Additional, zero hole formation occurs and any after-flame must be less than 2 seconds.

ISO 15797

NFPA 1971/1977 testing procedures are designed to gauge a vast array of elements in relation to the protective garments/ensemble for structural firefighting, with 1977 relating to wildfires. This standard specific the minimum requirements for the design, performance, testing and certification of or on protective gear.

NFPA 1971/1977 – Collar Height

NFPA 1971 specifies the minimum collar height of 3 inches. Safety and protective gear worn by fire fighters must meet this requirement because of a mandate to always wear protective hoods and firefighting helmets.

NFPA 1971/1977 – Total Heat Loss

Safety garments seeking certification in NFPA 1971 must have a measured total heat loss, where THL is the measurement of heat and moisture passing through the layers of the rescue gear. Breathable fabrics used in rescue gear are designed to let perspiration and interior moisture to escape. The standard for THL is 205 watts per meter squared (205 w/m2).

NFPA 1971/1977 – Heat Resistance

Conductive Compressive Heat Resistance (CCHR) is performed on the shoulder and knees of fire rescue gear to verify that these provide consistent protection when compressed. This test is run in both dry and wet conditions to simulate kneeling/crawling as well as carrying SCBA gear and a fully loaded tank. The test is intended to assign a rating that defines the time in seconds needed to achieve a temperature rise of 24° C. NFPA 1971 defines a required rating of 25 seconds.

NFPA 1971/1977 – Durability

In additional to all the other requirements of NFPA 1971/1977 for moisture barrier and flame/heat resistance, the NFPA 1971 requires that barrier layers be tested for resistance to general, light degradation. This is intended to measure water penetration resistance. This is typically a hydrostatic test done following severe UV exposure, done only on the moisture barrier.

Additional testing includes minimal length requirements, tensile strength, seam strength and other mechanical tests. Protective firefighting equipment, depending on the garment piece, is put through striker tests as well as shock and penetration tests followed by radiant heat and flame engulfment tests for continued durability under extreme conditions.

NFPA 1971 / NFPA 1977 / NFPA 2112

Garments and materials worn by professional workers come in contact with skin throughout the duration of their work day. Because of the environments they work in, water transfer and perspiration are normal. In conditions like these, especially where heat is involved, it’s easy for chemicals and other solvents and dyes used in the production process to leech from the clothing and transfer from the skin. Oeko-Tex standard 100 provides testing for harmful substances. This ensures there is no health risk in wearing the textiles. Before the 1990’s there was no standard, reliable product label for production companies, consumers or professionals to assess the safety of textiles or material components. Oeko-Tex holds those material suppliers, like LOXY, to modern standards of safety.

Defining the Oeko-Text Standard 100 Testing Process

The labs providing the testing of textiles go through approximately 100 test parameters based on international testing standards used around the world as well as other accepted testing methods. Beyond standard testing procedures, Oeko-Tex also uses simulation testing to take into account possible ways in which an individual could potentially be contaminated or poised – through the skin, through inhalation, etc. The tests that are performed depend on the type of chemicals that are used at each stage of the process, as these chemicals produce a change in the textiles. Testing procedures also vary depending on the use of the garment, as the more intense and intimate the exposure is to the garment (the more it comes in contact with the skin) the stricter the testing and limit values.

Testing includes

  • Substance prohibited by law such as carcinogenic dyes or related chemicals
  • Substances regulated by law including softeners, heavy metals, pentachlorophenol and formaldehyde
  • Substances that are not regulated or prohibited by law but can have an adverse effect on health, including pesticide, tin-organic compounds, and dyestuffs.
  • Parameters that include colorfastness and skin-friendly pH values (precautionary to safeguard the health of the wearer)


Certification in the Oeko-Tex 100 allows the use of the branded logo for Oeko-Tex, providing consumers with the knowledge that any materials and safety garments from Loxy have been tested and certified safe for professional use. Additional, any materials such as the Loxy reflective tape lines and seam sealing tape used in leisure or other activities and environments are certified to be safe for individual use in any environment. Materials will be labeled with the Oeko-Tex branded certification stating “Confidence in Textiles – tested for harmful substances according to Oeko-Tex Standard 100” with the appropriate test number listed on the certification to show the material satisfies the requirements of a common product class.

Oeko-Tex Product Classification

There are 4 classes of products where materials and textiles are broken up depending on their intended use and overall exposure. Oeko-Tex Class 1 – These are textiles for small children and babies (infants and newborns) up to the age of 3. This includes underwear, crawling or romper suits, bedding and linen, soft toys, etc. Oeko-Tex Class 2 – This product class includes textiles that, when used as intended, come into direct contact with skin over a large surface area. This includes bedding and linen, underwear, blouses, robes, etc. Oeko-Tex Class 3 – This is a product group that has minimal skin contact or does not come into contact with skin. Jackets, coats, liners, etc. Oeko-Tex Class 4 – Primarily furnishing materials that can include table linens, curtains, wall and floor coverings, machine and equipment covers, etc. When tested by Oeko-Tex, the textiles will be processed and allocated into one of the four listed categories. The assigned category will be listed clearly on the test certification. Adapted from Oeko-Text public material and information
