What is the purpose of the general clothing flammability standard?
The purpose of the regulation is to exclude hazardous flammable textiles and clothing made from these textiles from commerce. This standard specifies the method of testing the flammability of clothing and textiles intended for use in clothing, which are classified into 3 flammability classes according to the rate at which the fabric burns. The minimum standard states that Class 3 textiles are the most dangerous flammable fabrics and are not suitable for use in clothing due to their fast burning speed and strength.
Applicable Standards
16 cfr 1610 standard for the flammability of clothing textiles
16 CFR 1610 Standard for Flammability of Apparel Textiles.
What are the included wearables?
Wearable clothing includes any clothing or item that people wear. This standard applies to all textiles used for ** and children's clothing. Most children's pajamas must also meet stricter flammability requirements. Most hats, gloves, footwear, and fabrics used between the lining and outer fabric of garments do not need to meet this standard.
How are fabrics or garments tested to ensure they meet flammability standards?
Due to the details in the regulations, the following is a general overview of the testing requirements. For detailed information on testing equipment and procedures, specimen selection and other requirements, please refer to the regulations or contact Sedsway.
Five specimens measuring 2 inches and 6 inches are used for each test. Specimens are tested before and after dry cleaning and washing. The specimen is mounted on a specimen rack and placed in a test cabinet as specified.
Textiles with raised fiber surfaces, such as chenille, fluff and terry cloths, are brushed before testing. After the specimen has been conditioned (oven drying and dryer cooling), each specimen is placed in the test cabinet at a 45-degree angle. Expose the lower surface of the specimen (not the edge) to the gas flame for one second. Allow the specimen to burn upwards until the flame burns through the stop line, release the weight and stop the timer, or until the flame goes out.
To derive the time of flame spread, the timer stop time for all five specimens was averaged. If the time is less than 3 for the fabric of the ordinary surface5 seconds, or less than 4 seconds for fabrics with raised fiber surfaces, or if the specimen does not burn at all, or only one specimen has a burning time, then a second set of 5 specimens is tested. When testing the second set of samples, the time for flame spread was the average of the times of all 10 test specimens.
The regulation establishes three levels of flammability based on the time the flame spreads:
1.The flame spread time for Class 1 textiles, plain surface fabrics is 35 seconds or more, 7 seconds or more for embossed surface fabrics, or 0-7 seconds for embossed surface fabrics, the base fabric is not ignited or melted (generally, when the fuzzy surface fibers of the embossed fabric exhibit"Surface glitter"）。Class 1 textiles exhibit normal flammability and are acceptable for use in clothing.
2.Category 2 is only applicable to fabrics with raised fibers on the surface. Class 2 textiles have a flame spread time of 4 to 7 seconds (including 7 seconds), and the underlying fabric will ignite or melt. These fabrics exhibit a moderate degree of flammability and can be used in clothing. However, you should exercise caution when you make clothing from Class 2 fabrics, as the properties of these fabrics can lead to variations in their flammability test results.
3.The flame spread time for Class 3 textiles is less than 3 for smooth plain surface fabrics5 seconds, or less than 4 seconds for raised surface fabrics with backings, which will melt or burn from places other than igniting the flame. Class 3 textiles exhibit rapid and intense combustion and are dangerous flammables. You can't use Class 3 textiles in clothing.
Fabrics that may be classified as Class 2 or Class 3 textiles include clear rayon or silk, rayon chenille, suede or sherpa made of cotton or cotton blends, and certain cotton terry fabrics.
Which fabrics consistently meet the requirements of this standard?
Years of flammability testing have shown that the following fabrics consistently meet the requirements for Class 1 textiles and are exempt from reasonable and representative testing requirements for companies that issue flammability guarantees for these fabrics.
1.The weight per square yard is 2Plain weave fabric of 6 ounces or more, regardless of fiber content; And.
2.All fabrics (including plain and ribbed surfaces) made entirely of any of the following fibers or a combination of these fibers, regardless of their weight: acrylic, molded, nylon, olefin, polyester, and wool.
How can apparel manufacturers, importers, distributors, or retailers ensure that their fabrics or garments are not dangerously flammable?
1.You can purchase fabrics or garments made from the above exempt fabrics.
2.You can perform reasonable and representative tests on fabrics (before cutting and sewing into garments) or finished garments.
3.You can purchase fabrics or garments from a merchant who guarantees compliance with these flammability requirements. In order to issue a warranty, the Merchant must conduct reasonable and representative testing for each item covered by the Warranty, and must maintain a record of the tests in support of the Warranty (except for the exempt fabrics listed above). For more details on warranty and record-keeping requirements, please refer to the Ordinance.
