When it comes to ensuring the safety and protection of individuals in various industries, flame resistant (FR) clothing plays a crucial role. Understanding the standards and regulations surrounding FR clothing is essential for fabricators, as it allows them to meet specific market and product requirements.

Flame resistant clothing is designed to withstand exposure to arc flash, flash fire, low visibility, and other hazardous conditions. To ensure the quality, comfort, and functionality of FR clothing, there are various standards and test methods in place.

One of the key aspects of FR clothing is the FR rating, which measures the fabric's flammability when exposed to specific sources of flame. This rating is achieved through a series of North American safety tests that assess whether the fabric meets certain criteria for safety.

The responsibility for flame retardance certifications primarily falls on fabric suppliers. However, fabricators need to be familiar with the applicable codes and standards to properly advise their clients. This is especially important for fabricators involved in the production of massive stadium structures, window shades, and other products that require FR certification.

FR fabrics can be classified into two categories: inherently FR and coated FR. Inherently FR fabrics are made from fibers that possess flame retardancy without the need for post-treatments. These fabrics retain their FR properties throughout their lifespan. On the other hand, coated FR fabrics require treatments or coatings to achieve flame retardancy. While these fabrics can also pass the necessary tests, their FR properties may diminish over time due to washing or dry cleaning.

The testing of FR fabrics is typically consistent on a nationwide basis. The National Fire Protection Association (NFPA) publishes one of the main building codes that cover a wide range of products. Additionally, there are specific tests for aircraft, passenger rail cars, and passenger vessels.

Some states and cities have their own regulations and tests, such as California's Title 19 and New York City's requirements outlined in Title 27 of NFPA 701. Fabric suppliers within the Industrial Fabrics Association International (IFAI) often have their products tested through outside facilities and can provide the necessary test data and certificates.

While NFPA 701 is the standard for the industry, there are other important tests to consider, such as ASTM 84 for interior wallcoverings. This test focuses specifically on permanent fabrics used for interior walls.

Exterior applications that utilize architectural fabrics, such as awnings and tents, also require FR certification. These fabrics are subject to the same fire retardant guidelines as interior fabrics due to their close contact with humans.

It's important to note that different countries have their own FR tests and certifications. NFPA is considered the governing body for FR standards in North America, while Europe typically utilizes B2 and M1 certifications.

In summary, understanding flame resistant clothing standards is crucial for fabricators and suppliers in meeting specific market and product requirements. By adhering to these standards and test methods, fabricators can ensure the quality, comfort, and functionality of FR clothing, promoting safety in various industries.

Test Methods for Fire Resistant Fabrics

When it comes to ensuring the fire resistance of fabrics, proper testing methods are essential. These tests determine whether a fabric meets the necessary standards for flame retardancy. Here are some of the most common test methods used for fire resistant fabrics:

NFPA 701: This is a widely recognized test method developed by the National Fire Protection Association (NFPA). It measures the flame propagation of textiles and films. Fabrics are subjected to a small-scale burn test, and their flame, char length, and flaming residue are measured. If a fabric meets the criteria set by NFPA 701, it is considered flame retardant.

ASTM E84: This test method, also known as the Steiner tunnel test, measures the surface burning characteristics of building materials. It evaluates the flame spread and smoke development of a material when exposed to a controlled flame source. ASTM E84 is commonly used for interior wallcoverings and is especially important for permanent fabrics used on interior walls.

California Title 19: In California, the Office of the State Fire Marshal (OSFM) has its own set of regulations for flame retardant fabrics. Fabrics used in public spaces must comply with the requirements outlined in Title 19 of the California Code of Regulations. The OSFM-approved laboratories conduct tests according to the specified test methods, such as CCR, Title 19 Section 1237.1 or 1237.2, depending on the indoor or outdoor use of the material.

CPAI 84: This test method is specific to camping tentage materials and is widely accepted in the industry. It measures the flammability of fabrics used in tents and similar structures. Fabrics that meet the requirements of CPAI 84 are considered flame retardant and safe for use in outdoor applications.

ASTM E119 and UL 1709: These test methods evaluate the fire resistance and flammability of textile products in extreme conditions. They are often used for products such as curtains, window shades, and draperies in public occupancy buildings. The tests simulate real fire scenarios and assess the performance of fabrics under intense heat and flame exposure.

It is important for fabricators and fabric suppliers to work together to ensure that the fabrics they use meet the necessary fire resistance standards. By understanding the specific test methods and regulations applicable to their products, fabricators can provide accurate and reliable information to their clients.

In the United States, one of the main regulatory codes for fire resistant fabrics is the National Fire Protection Association (NFPA) standards. The NFPA 701: Standard Methods of Fire Tests for Flame Propagation of Textiles and Films is widely recognized and used as a benchmark for assessing the flame resistance of drapery fabrics used in public spaces. Under this code, fabrics are tested by burning a small sample and measuring the flame, char length, and flaming residue. If the fabric meets the standards in these areas, it is considered flame retardant and receives NFPA 701 certification.

While the NFPA 701 is a national standard, it is important to note that compliance with this code is not a law or regulation in itself. Instead, the authority to establish and enforce regulations regarding flame retardancy is granted to state and local governments. Many states and cities require that draperies used in public spaces meet the NFPA 701 standards. However, some regions have developed their own specific standards and procedures.

For example, in California, drapery used in public spaces must comply with Title 19 of the California Code of Regulations. These requirements are separate from NFPA 701 standards and fabrics must be registered with the State Fire Marshal to document compliance. Similarly, New York City requires fabrics to meet the requirements outlined in Title 27 of the New York Administrative Code, while the City of Boston requires approval of fabrics prior to use.

It is important to note that some venues may also have their own specific requirements for drapery fabrics. Radio City Music Hall, for instance, not only requires compliance with New York City regulations but also requests specific information about each sewn drapery piece.
