TECHNICAL BULLETIN 129 FLAMMABILITY TEST PROCEDURE FOR MATTRESSES FOR USE IN PUBLIC BUILDINGS

1.SCOPE
1.1 The purpose of this test method is to determine the burning behavior of mattresses used in public occupancies by measuring specific fire-test responses when the mattress is subjected to a specified flaming ignition source under well ventilated conditions.

1.2 This test method is applicable only to the finished article of mattresses and other complete bedding systems and does not apply to testing of individual component materials used in the construction of bedding systems, such as ticking materials, foams, cotton battings, etc.

1.3 The public occupancies include, but are not limited to health care facilities, old age convalescent and board and care homes, college dormitories and residence halls.

1.4 Data are obtained describing the burning behavior from ignition until all burning has ceased, or a period of 1 hour has elapsed, or flashover appears inevitable.

1.5 Although this test method is primarily a test for mattresses, other bedding systems may be evaluated using procedures described in Appendix E.

1.6 The rate of heat release of the burning specimen is measured by an oxygen consumption technique.

1.7 Fire testing of products and materials is inherently hazardous and adequate safeguards for personnel and property shall be employed in conducting these tests. This standard may involve hazardous materials, operations, and equipment.

1.8 It is the intent of the Bureau that mattresses complying with this test method be safer when subjected to the ignition conditions specified by this method. This type of ignition may be typical of arson or incendiary fires or common accidental fires in public occupancies. The Bureau expects manufacturers and others attempting to comply with this method will also seek to make safer mattresses and will not attempt to compromise the intent of the method in any manner.
