Frequently Asked Questions:-

What is ISO 5659?

It specifies from the exposed surface of specimens a method of measuring smoke production of materials predicting the density of smoke that can or composites. No basis is provided for be generated by and flame under other (actual) exposure the materials upon exposure to heat conditions.

What is the difference between ASTM and ISO?

ASTM is a national ISO organization ISO is an organization that has representations from is a part of international all countries including ASTM.
