11、eat construction. a0 D. SUMMARY OF TEST METHOD These test methods consist of several tests used to evaluate the cigarette ignition resistance of upholstery cover fabrics, barrier (interliner) materials, resilient filling materials, and decking materials used in the manufacture of upholstered furnitu

12、re. Each test involves a miniature assembly consisting of the component to be tested along with other specified materials, mounted on a plywood mock-up that resembles a small chair seat and back. The assembly is exposed to a lighted cigarette as an ignition source. E. SIGNIFICANCE AND USE E.1 These

13、test methods are intended to estimate the performance of upholstered furniture under conditions of exposure to a smoldering cigarette. This is accomplished by testing furniture component assemblies. However, interactions between components in production furniture are not necessarily predicted by com

14、ponent assembly testing. E.2 These test methods are not intended to measure the performance of upholstered furniture under conditions of open flame exposure and do not indicate whether the furniture will resist the propagation of flame under severe fire exposure or when tested in a manner that diffe

15、rs substantially from the test standard. E.3 The results obtained with a material component tested in mock-up, in accordance with these test methods, do not necessarily indicate the performance of the same material component in other geometrical configurations, such as in full size furniture. F. TES

16、T FACILITY AND HAZARDS The exhaust system and hazards are described in Annex A. G. APPARATUS AND STANDARD TEST MATERIALS The apparatus and standard test materials are specified in Annex B and C. H. CONDITIONING Condition test specimens and cigarettes prior to the test for a minimum of 24 hours at 21

17、 3 C (70 5 F) and less than 55% relative humidity. If conditions in the test area are not the same as in the conditioning area, tests should begin within 10 minutes of removal of samples from conditioning area. SECTION 1: COVER FABRIC TEST 1.1 SCOPEThis test method measures the tendency of upholster

18、y cover fabrics to smolder and contribute to fire propagation, when subjected to a smoldering ignition source. For cover fabrics that pass this section, the first layer of filling materials located below the cover fabric shall also meet the test requirements of section 3 of this test method. a1 1.2

20、rglass board. If testing multiple specimens simultaneously, place the individual test specimens at least 6 inches (152 mm) apart to avoid heat transfers between specimens. 1.3.2: After completing test procedure step 11.6, the test operators shall start timers to record testing time. 1.4 PASS/FAIL CR

21、ITERIA A material is considered to pass or fail based on the following criteria: 1. A single mock-up test specimen fails to meet the requirements of this test procedure if any of the following criteria occurs: a) The mock-up test specimen continues to smolder after the 45 minute test duration; b) A

22、vertical char length (measured as specified in step 11.9 of ASTM E1353-08a 01) of more than 1.8 inches (45 mm) develops on the cover fabric. c) The mock-up test specimen transitions to open flaming. 2. The cover fabric passes the test if three initial mock-up specimens pass the test, i.e., the cigar

23、ettes burn their full length and the mock-ups are no longer smoldering. 3. If more than one initial specimen fails, the cover fabric fails the test. 4.
