缎带的燃烧测试

有一条缎带需要做ASTM 燃烧测试(原材料测试),我搞不明白应该是把它当string豁免呢,还是应该当FABRIC来烧一下,谢谢

不知道我这样理解对不对,ASTM F963-08
3.1.15 CORD--a length of slender, flexible material including monofilaments, woven and twisted cord, rope, plastic textile tapes, ribbon, and those fibrous materials commonly called string.

而A 4.2.5 strings--long slender flexible material usually consisting of several strands ( as of thread or yarn ) woven or twisted together, usually used to bind, fasten, tether, or tie. This does not iinclude string when used, for example, for hair on a doll


3.1.15把ribbon等都叫做了string,而A4.2.5则没有这样定义,我能不能把3.1.15里的定义用到A4.2.5上,把ribbon也当做string豁免呢?谢谢

我个人觉得:
                  1.要搞清楚带子的材料是否属于FABRIC范畴
          2.要搞清楚带子的尺寸，是否能达到A5要求的尺寸，
          如果符合1.2则就要按A5烧
          以上为个人观点，请指正！

现在是材料屬於FABRIC,但尺寸不够,那是按照A4来豁免还是按照A5的尺寸不够来豁免呢?谢谢

尺寸不够豁免

尺寸不够2inch应该可以豁免啊！
