Demystify: 

The US mostly uses ASTM - American Society for Testing and Materials. I was on the ASTM E27 committee for a number of years which deals with Hazard Potential of Chemicals. This includes flammability.

We did pay attention to ISO standards, but we never had complete consensus. There was always a huge amount of debate on the E27 committee on the various methods. Of course, the testing methods were never perfect and always had flaws.

I realized I made a mistake. The US is always higher than ISO 10156 which is the accepted International standard for flammable gases. Sorry for the error
