Both of these standards are relevant to testing materials at high temperatures.
When can we use ISO 834 and when can we use Standard ASTM E119?
What is the main difference between them? Is Fire Curve similar in them?
Using specimens similar to those described in the draft revision of ASTM E 119, tests were conducted in floor and wall fire test furnaces. The tests were designed to compare the practical consequences of following the ASTM E 119 and ISO 834 specifications for measuring and controlling the nominal furnace temperature. It has been found that in fire tests of shorter duration, perhaps up to 1.5 h, the ASTM test is slightly more severe than the ISO test. In longer tests the difference in severities is negligible.
ISO are international Standards that has representations from all countries Which include ASTM, Both Provides guideline for technical standards for a wide range of materials, products, systems, and services. For example, building materials need to meet the requirements of ASTM in North America, and in Europe or(Globally) by ISO.
