ANSI/UL 94 VTM薄质材料垂直燃烧测试

ANSI/UL 94材料可燃性测试– 标准名称

ANSI/UL 94Test for Flammability of Plastic Materials for Parts in Devices and Appliances

ANSI/UL 94设备及电器塑料部件的标准燃烧测试方法。

ANSI/UL 94材料可燃性测试 – 标准概述

这些要求涵盖了用于设备和器具部件的聚合物材料的可燃性测试。它们旨在作为其对特定应用的可燃性的可接受性的初步指示。

These requirements cover tests for flammability of polymeric materials used for parts in devices and appliancesThey are intended to serve as a preliminary indication of their acceptability with respect to flammability for a particular application.

ANSI/UL 94 VTM薄质材料的垂直燃烧测试 –测试标准

当采用20mm垂直燃烧测试时，由于测试材料薄、扭曲、收缩或烧致夹具而无法进行，本测试方法就是针对这种材料规定的测试方法。该类材料还具有使长度为200mm，宽度为50mm的试样，纵向缠绕在13mm直径的卷轴上的物理性能。

This test is intended to be performed on materialsthat due to their thinnesseither distortshrinkand/or are consumed up to the holding clamp when tested using the test described in the 20 mm Vertical Burning Test.This test shall only be performed after it has been determined that the samples cannot meet the requirements of the 20-mmVertical Burning Test The materials shall also possess longitudinally around a 13 mm diameter mandrel
