Don’t make presumptions about testing based on externalities like certifications when you don’t know enough about how the company operates in conducting their own testing.
You presume that because they don’t seek certifications by external agencies, but somehow they’re not doing testing. If you had seen their lab, you would understand that they’re testing with greater rigor, using different methods, than required for those certifications, for example, using TGA vs. NOACK.
TGA is considered by many to be the superior method of determining volatility.
