Our customer frequently ask us to perform a calorimeter on the HVAC compressors we sell to them. Typically we have the factory do this for free but the factory is in Korea, so this takes time. So we then started to consider getting our own machine and doing the test ourselves. That quickly migrated to getting NRTL and purchasing a psychrometric room in addition to the calorimeter. So my question is what do I need to become a NRTL, I'm seeing that I would need accreditation from an A2LA or similar organization. And if I am understanding this correctly we would need ISO 17025 to get the accreditation. So my question is am I understanding this correctly? I hope this made sense its a long story and I am sure you don't want all the crazy details. Any help or advise you can give would be appreciated.
