Fire Testing Laboratories and International Standards

Do your products meet the fire testing standards of every country you import to? Learn what you need to know about fire testing standards and lab testing here.

Why Manufacturers Need Fire Testing Conducted in Laboratories

Do your products meet the fire testing standards of the country where you want to import goods?

It can be tricky to determine, for two reasons: the flame testing standards of each county vary, and different types of products require different testing methods and standards.

In this article, we will explain the types of products that need fire testing conducted in laboratories, and what tests to perform.

What is Fire Testing in Manufacturing?

Fire tests, or flammability tests, measure how easily materials ignite, how quickly they burn, and how they react when burned. Fire testing laboratories use various testing methods, depending on international flammability testing standards and the type of material being tested.

These laboratories perform tests on samples of textiles and fabrics in controlled conditions to determine the following:

  • Fire resistance - To determine the ability of materials used in the manufacturing of products to withstand fire or provide protection for a period of time.
  • Flame spread - To measure the propagation of flames away from the source of ignition, across the surface of the sample and evaluate the potential for flames spreading in the event of a fire.
  • Reaction to fire - To evaluate the extent to which a product contributes to fire when exposed to flames.
  • Flashpoint - To determine the temperature required for combustible liquids to catch fire.

Why do Manufacturers Need Fire Testing?

In the US and European markets, there are regulations governing the import and sale of most products, including flammability standards such as the EU Toy Safety Directive 2009/48/EC. Most other well-developed consumer markets have similar regulations. Therefore, manufacturers and suppliers must use fire testing laboratories to have their products tested and certified to be fit for sale.

Types of Products Which Require Fire or Flammability Testing

Regulations governing fire testing methods vary depending on the type of product and the material it’s comprised of, such as:

  • Clothing textiles and vinyl plastic film for apparel
  • Children’s sleepwear
  • Carpets and rugs
  • Drapes and drapery linings
  • Polymers (plastics) used in electronic products and appliances
  • Fabrics and textiles used in furniture and bedding
  • Interior and exterior building materials
  • Toys

Furniture for the UK market

According to the UK’s Fire Safety Alliance, domestic furniture fires kill 1,500 people a year in Europe and seriously injure a further 15,000. The UK introduced stringent fire safety standards and regulations for upholstered furniture in 1988. The UK and Ireland are the only European member states to adopt such standards for furniture. Sofas and mattresses predominantly fall into this category.

Fire testing of sofas and mattresses measure heat release, smoke release and opacity, combustive gas release, and total mass loss.

This type of flammability test is done by igniting the furniture with a lit cigarette or an open flame to simulate accidental or deliberate fires, and evaluate how the product reacts.

Flammability of fibers used in clothing

The flammability of clothing depends on the fiber, fabric, and design of the garment.

  • Natural Fibers
    • Wool: will catch fire but resists burning and extinguishes itself
    • Cotton: highly flammable, burns rapidly
    • Silk and linen: very flammable, burns rapidly
  • Man-made Fibers - Rayon, acetate, and triacetate: highly flammable (may also melt and cause serious burns) Nylon, polyester, acrylic, and olefin: not highly flammable but may melt and cause serious burns

Children’s sleepwear for the US market

The US Consumer Product Safety Commission demands that all children's sleepwear (pajamas, nightgowns, and robes) manufactured in, or imported into, the United States must meet the Federal standards of flammability by passing the flame test.

Flammable fabrics can be made flame retardant by using inherently flame retardant fibers or by adding a chemical flame retardant finish to the fabrics. However, many flame retardant chemicals are regulated because they can be toxic. In this case, additional chemical testing may be required in order to comply with health, safety, and environmental regulations.

Care Labeling

If flame retardant chemicals are used in the manufacture of garments, proper care instructions for washing and ironing must be added to the clothing labels, informing the consumers on how not to decrease the flame retardant properties.

What Lab Tests Do Manufacturers Need to Conduct and What are the Benefits?

Both domestic manufacturers and importers of consumer products across a wide range of industries must prove that their products satisfy national health and safety standards, making testing and certification essential for successful placement on the market.

Putting your products through fire testing with an accredited third-party product-testing laboratory allows you to qualify for the appropriate certification for your product and the destination market.

By acquiring certification, you also reduce the risk of your product being rejected or recalled from the market for non-compliance. In addition, you mitigate the risk of paying fines or compensation in the event a consumer takes legal action as a result of a fire involving your product.

Destination markets worldwide enforce consumer safety regulations governing fire testing standards. While the testing standards for different countries are similar – heat and/or flame is applied to product samples to measure flame resistance, the spread of flame, and reaction to being burned – each destination market has its own specific fire testing requirements.

Here are the types of flame tests that are generally performed on consumer products and textiles to comply with worldwide consumer protection standards.

Vertical Flammability Testing

A sample of the fabric or textile is held vertically over a bunsen burner for between 10 and 20 seconds. The following observations are made:

  • Length of time the sample burns after the flame is removed
  • How much of the specimen burns
  • Any dripping flaming particles

Horizontal Flammability Testing

This test is used to observe whether the sample material continues to burn after the test flame has been removed. This determines the rate at which the specimen burns.

Flammability of Mattresses and Furniture

Flammability testing of mattresses and furniture is an essential part of ensuring fire safety for consumers. These flammability tests are done in a burn-room to measure heat release, smoke release and opacity, combustive gas release, and total mass loss. This type of fire testing ignites mattresses or furniture with a lit cigarette or a large open-flame to determine how a product will react in cases of accidental and intentional fires.


Fire testing standards for garments commonly require that strips of fabric from various parts of the garment, including seams and trim, must self-extinguish within a short time, usually about 10 seconds, and will not burn more than a few inches when exposed to a vertical flame. The same garment must meet the same requirements after it has been laundered up to 50 times.


Toys destined for European markets must comply with specific physical and flammability requirements outlined in the EU Toy Safety Directive 2009/48/EC.

The directive specifies the categories of flammable material that are prohibited in all toys in order to reduce the risk of burn injuries. The toys considered as presenting the greatest fire risk are: toys to be worn on the face or head such as fake beards, mustaches, wigs, masks, hoods, and headdresses; costumes; soft toys; and toys intended to be entered by a child.

Fire testing for toys verifies the rate that flames spread, or the maximum ‘after-flame time,’ giving the child enough time to drop the toy or become distanced from it before serious injury occurs.

Flame Testing Standards Adopted by Different Countries

If you’re developing a product for a particular regional market, it’s important to be aware of the diverse flame testing standards adopted by individual countries as well as the standards governing particular types of products and industries in those countries. Here’s a list of flame testing standards adopted by different countries.
