ASTM F963燃烧

622

ASTM F963附录4做固体燃烧时,第三方实验室一般是采用0.1in/s做合格线呢?还是以制造商的附加导则0.15in/s做为合格线呢??
我有一样品烧了4次都是0.12左右,按照A4.6.3.4,那是应该四舍五入到0.1吗(那是不是就合格了呢)??可按照A4.6.3.5最大可接受的为0.1in/s,又把我搞糊涂了 ....呵呵

四舍五入到一位小数就可以啦

622

我的意思是0.12in/s四舍五入到1位小数就是0.1in/s了.可ASTM里是这样描述的.
A4.6 Requirements
A4.6.1 A toy shall be considered a flammable solid if it
ignites and burns with a self-sustaining flame at a rate greater
than 0.1 in./s (2.5 mm/s) along its major axis.

A4.6.3.5 Level of acceptance = 0.1 in./s (2.5 mm/s), maximum,
along the major axis.
那我是不是可以这样理解,按照A4.6的要求,0.12in/s四舍五入到0.1in/s也就是合格的.....对吗??谢谢
