Frequently Asked Questions:-

What is ISO 5659?

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

What is the Plastic Smoke Density test?

It is also known to be used for measuring the smoke-producing ASTM E1354 Cone Calorimeter,  characteristics of plastics under controlled conditions of combustion or decomposition. … Other as the Exit Sign Smoke Test, is intended smoke test apparatus, for example, E662 Smoke Density Chamber, etc

What is the difference between ASTM and ISO?

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

What do you mean by ISO?

International ISO is an independent, non-governmental, international Organization for Standardization organization that develops safety, and efficiency of products standards to ensure the quality, services, and systems.
