TB 117 美国软体家具材料阻燃测试 -测试内容、周期及样品要求

TB 117: 软体家具的弹性填充材料的阻燃测试-要求,测试流程和仪器

State of California, Department of Consumer Affairs Bureau of Home Furnishing and Thermal Insulation, Technical Bulletin 117(TB 117):Requirements, Test Procedure and Apparatus for Testing the Flame Retardance of Resilient Filling Materials Used in Upholstered Furniture

TB 117标准概述:

  1. 该标准已经有30年的使用时间,由于该标准有较大的实用价值,所以准备完成部分补充后在全美国推广。
  2. TB117是在充分研究火灾发生原因后,从实际出发而制定的,更为科学。其测试火源是香烟焖烧测试、模仿火柴点燃测试及模仿一定量的报纸点燃测试,与实际泡沫起火场景相符。
  3. 随着家具制品出口量的增加,采用该标准可以避免由于技术法规的不同引起的技术贸易壁垒。

TB 117适用范围:

针对根据加州TB117标准规定内列明的软垫家具的弹性填充材料。

TB 117标准解析:

  1. 弹性填充材料香烟测试:每个样品的炭化尺度应接近于0.1英寸
  1. 弹性填充材料闷燃测试
每个泡沫体测试3个样品 如果所有的样品非闷燃残留超过80% 通过
如果2个或多于2个测试样品非闷燃残留少于80% 不通过
如果1个测试样品非闷燃残留少于80% 增加测试3个样品 如果1个测试样品非闷燃残留少于80% 不通过
如果所有的测试样品非闷燃残留超过80% 通过
