5.1 This test method is suitable to assess the fabric burn rate of sleeping bag fabrics.

5.2 This test method is applicable to all sleeping bags.

5.3 This test method is technically equivalent to CPAI-75, which is used for the acceptance of commercial shipments of sleeping bags.

5.4 When combustible fabrics are used for sleeping bags they are potentially dangerous to the user because of their ease of ignition (since all combustible materials will ignite) and because it is possible that they will exhibit a high burn rate.

5.5 Most fabrics used to make sleeping bags are combustible (see 3.2.2). Fabrics can be combustible due to the inherent chemical composition of the fabric material or due to the finishing processes used or both.

5.5.1 Optionally, if there is a query as to whether a specific fabric used for a sleeping bag is combustible, it shall be tested in accordance with Test Method E136. If the fabric complies with the requirements of Test Method E136 it shall be considered noncombustible and shall be deemed to meet the performance requirements of this test method.

5.6 Changes in finishes or in fabric surface treatments can exert a large effect on the fabric flammability. Therefore, sleeping bags shall be tested both before and after cleaning or aging in accordance with one of the procedures in 7.3, in accordance with the manufacturer's instructions.

5.7 In this procedure, the specimens are subjected to one or more specific sets of laboratory test conditions. If different test conditions are substituted or the end-use conditions are changed, it is not always possible by or from this test method to predict changes in the fire-test-response characteristics measured. Therefore, the results are valid only for the fire test exposure conditions described in this procedure.

5.8 It must be understood, moreover, that no guarantee can be given and none is implied that sleeping bags complying with the performance requirements of this test method will not be hazardous under certain conditions.

5.9 It is feasible that the fabric will pass the test requirements as received but fail the requirements after cleaning. In that case, the report shall indicate that the fabric is not suitable for cleaning or aging (as appropriate).

Scope

1.1 This fire-test response test method contains a method to assess the flammability, expressed as a burn rate, of sleeping bags which use various materials and constructions in their manufacture.

1.2 Sleeping bags that comply with the requirements in this test method shall be permitted to be labeled as complying with the appropriate requirements, to facilitate the identification of products conforming to this test method.

1.3 This test method is technically equivalent to the flammability standard CPAI-75, issued by the Industrial Fabrics Association International (see 2.2), and which has been in use as a flammability requirement for the sleeping bag industry in the U.S.

NOTE 1: CPAI-75 expresses burn rate in units of inches/minute while this test method expresses burn rate in units of centimetres/minute.

1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.5 This standard is used to measure and describe the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products, or assemblies under actual fire conditions.

1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.7 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.

1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Test Requirement 测试要求：

1.  平均燃烧速度不超过15cm/min (6in./min)
2. 任何一个样品的燃烧速度不能超过20cm/min

一、Preparation and Conditioning of Testing Specimens 测试环境及准备

1. 样品：30cm (12in.)×36cm (14in.), 若有因样品睡袋结构的原因而不能剪出指定的尺寸，可以从相同的材料下剪下尺寸为30cm (12in.)×71cm (28in.)的样品，折叠形成测试样品。
2. 水洗：水洗五个测试样品，洗三次，根据生产商推荐的方法。
3. 压缩：测试前要将样品压缩50%至其正常厚度的一半并保持24小时。
4. 回复：在压缩24小时后，让样品自然回复至少1小时。

二、Test Method

1. 安装样品于测试架上，夹持三个缝纫过的边
2. 在距离样品的一端（点火那一端）3.8cm and 28cm处放上两根白色#50丝光处理的棉线，线的两端系上重锤，悬挂之而拉紧棉线。两根的位置分别是记时的开始点和结束点
3. 调整火源，将其放在已放了安装好样品的测试架的测试柜中，燃烧管tube的顶端离样品的距离为1.9cm (0.75in.)
4. 拉下测试柜的门
5. 让火源对样品烧30秒
6. 当烧到第一根线，重锤掉下时开始记时，到烧到第二根线时或火熄灭时停止记时，并记录，测量火焰蔓延的距离并记录
7. 重复测试剩余下样品

Sample Size 样品数量 / 送样规格:  3 pieces of final products 三套成品
