A fire test can be conducted to determine the degree of flammability. Test standards used to make this determination but are not limited to the following: Underwriters Laboratories UL 94 Flammability Testing; International Electrotechnical Commission IEC 60707, 60695-11-10 and 60695-11-20; International Organization for Standardization ISO 9772 ...
The test was developed in 1944 by Al Steiner of Underwriters Laboratories, and has been incorporated as a reference into North American standards for materials testing as tests ASTM E84, NFPA 255, UL 723 and ULC S102. These standards are in widespread use for the regulation and selection of materials for interior building construction ...
UL 94, the Standard for Safety of Flammability of Plastic Materials for Parts in Devices and Appliances testing, is a plastics flammability standard released by Underwriters Laboratories of the United States. [1] The standard determines the material's tendency to either extinguish or spread the flame once the specimen has been ignited.
A fire test can also mean an ad hoc test performed to gather information in order to understand a specific hazard, such as a construction or storage configuration. Tests can be bench scale (e.g., flammable liquid flash point), medium scale (e.g., storage commodity classification), or full scale (e.g., replication of an entire rack storage ...
This test method measures flame growth on the underside of a horizontal test specimen, using the Steiner tunnel test. The result is derivation of a Flame Spread Index ( FSI ), [ 2 ] which is a non-dimensional number which is placed on a relative scale in which asbestos-cement board has a value of 0, and red oak wood has 100.
Standard methods for testing polymer flammability vary among countries; in the United States common fire tests include the UL 94 small-flame test, the ASTM E 84 Steiner Tunnel, and the ASTM E 622 National Institute of Standards and Technology (NIST) smoke chamber. [1]
Testing in Canada is in accordance with ULC-S101 as required by the local building code.. Inherently fire resistive cables can be tested to UL 2196, Tests for Fire Resistive Cables, whereas enclosures for cables that are not inherently fire resistive can be tested to UL 1724 or USNRC Generic Letter 86-10, Supplement 1 in North America, or BS476 in the United Kingdom or DIN4102 in Germany.
The International Electrotechnical Commission publishes the 60079 series of standards [2] which defines a system for classification of locations, as well as categorizing and testing of equipment designed for use in hazardous locations, known as "Ex equipment". IEC 60079-10-1 covers classification of explosive gas atmospheres, and IEC 60079-10-2 ...
