本标准代替GB/T9900—1988《抽出式难燃橡胶导风筒》,原化工行业标准HG/T3325—1982《矿用胶布导风筒》也同时废止。本标准规定了橡胶或塑料涂覆织物导风筒的分类、结构、技术要求、试验方法、检验规则、包装、标志、运输和贮存等。本标准适用于以橡胶或塑料涂覆织物制成的正、负压导风筒。主要应用于矿井、隧道、水利工程、地铁和人防工程等。 本标准与GB/T9900—1988相比主要变化如下:
———名称不同;
———适用范围不同,增加了正压导风筒的要求(见第1章);
———增加了对涂覆织物物理机械性能的要求(本版的5.1.2);
———增加了长度为30m 和50m 的导风筒规格及外观检验要求(本版的5.2.1和5.2.2);
———增加了直径为1000mm 至1600mm 规格导风筒的要求及试验方法(本版的5.2.1和第6章);
———增加了导风筒接缝强度的要求(本版的5.2.3)。
