1.1 本耐火试验响应标准涵盖了一个小规模实验室程序，用于确定固体塑料材料的比较燃烧特性，使用20 mm（50W）预混合火焰施加在垂直位置固定的试样底部。 注1: 本试验方法和ANSI/UL的20 mm（50W）垂直燃烧试验（V-0、V-1或V-2） 94相当。 注2: 本试验方法与IEC 60695-11-10的试验方法B等效。IEC 60695–11–10已取代ISO 1210 注3: 有关通过本试验方法燃烧到固定夹的材料的更多信息，请参阅试验方法 D635 . 关于薄板和薄膜形式的软塑料的试验方法，请参阅试验方法 D4804 . 有关比较燃烧特性和耐烧穿性的更多信息，请参阅测试方法 D5048 . 1.2 本试验方法适用于用于设备和器具零件的聚合物材料。 结果旨在初步表明其在特定应用的易燃性方面的可接受性。材料的最终验收取决于其在符合适用于此类设备的标准的完整设备中的使用。 1.3 附录中描述的分类系统旨在保证产品的质量和预选部件材料。 1.4 本试验可能适用于塑料以外的非金属材料。此类应用不在本技术委员会的范围内。 1.5 当用于建筑施工、装饰或内容物（如墙壁和地板覆盖物、家具、装饰物等）时，本试验方法不包括塑料。此外，本试验不评估耐火性（按小时额定值）、火焰传播、烟雾特性和热释放率。 存在其他耐火试验，并应用于评估这些预期最终用途产品配置中材料的易燃性。 1.6 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.7 本标准用于测量和描述材料、产品或组件在受控条件下对热量和火焰的响应，但其本身并不包括在实际火灾条件下对材料、产品或组件进行火灾危险或火灾风险评估所需的所有因素。 1.8 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.9 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 在本试验方法的条件下，试验结果表示特定形状材料的余火和余辉时间（秒）。 5.2 材料厚度、着色剂和挥发性成分可能损失的影响是可以测量的。 5.3 将结果制成表格后，可能有助于比较材料的相对性能，并有助于材料选择。 5.4 在该程序中，样本经受一组或多组特定的实验室测试条件。 不同的测试条件可能会导致测得的火灾测试响应特性发生变化。因此，结果仅对本试验方法中描述的火灾试验暴露条件有效。

1.1 This fire-test-response standard covers a small-scale laboratory procedure for determining comparative burning characteristics of solid-plastic material, using a 20-mm (50W) premixed flame applied to the base of specimens held in a vertical position. Note 1: This test method and the 20 mm (50W) Vertical Burning Test (V-0, V-1, or V-2) of ANSI/UL 94 are equivalent. Note 2: This test method and Test Method B of IEC 60695–11–10 are equivalent. IEC 60695–11–10 has replaced ISO 1210. Note 3: For additional information on materials that burn up to the holding clamp by this test method, see Test Method D635 . For test methods of flexible plastics in the form of thin sheets and film, see Test Method D4804 . For additional information on comparative burning characteristics and resistance to burn-through, see Test Method D5048 . 1.2 This test method was developed for polymeric materials used for parts in devices and appliances. The results are intended to serve as a preliminary indication of their acceptability with respect to flammability for a particular application. The final acceptance of the material is dependent upon its use in complete equipment that conforms with the standards applicable to such equipment. 1.3 The classification system described in the appendix is intended for quality assurance and the preselection of component materials for products. 1.4 It is possible that this test is applicable to nonmetallic materials other than plastics. Such application is outside the scope of this technical committee. 1.5 This test method does not cover plastics when used for building construction, finishing or contents such as wall and floor coverings, furnishings, decorative objects etc. In addition, the fire resistance (in terms of an hourly rating), flame spread, smoke characterization and heat release rate are not evaluated by this test. Other fire tests exist and shall be used to evaluate the flammability of materials in these intended end use product configuration. 1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.7 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. 1.8 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. 1.9 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. ====== Significance And Use ====== 5.1 The tests results represent afterflame and afterglow time in seconds for a material of specified shape, under the conditions of this test method. 5.2 The effect of material thickness, color additives, and possible loss of volatile components is measurable. 5.3 The results, when tabulated, are potentially useful as a reference for comparing the relative performance of materials and as an aid in material selection. 5.4 In this procedure, the specimens are subjected to one or more specific sets of laboratory test conditions. Different test conditions will likely result in changes in the fire-test-response characteristics measured. Therefore, the results are valid only for the fire-test-exposure conditions described in this test method.
