Before you commit to this standard
Two things decide whether a result to this standard will be accepted: whether the measurement was made by a laboratory whose scope covers it, and whether the specimen and conditions matched what the standard actually requires. A number produced outside either of those is not wrong, but it is not evidence either.
If you are not certain which standard your specification calls for — and specifications frequently name a superseded edition, or name an ISO standard where the ASTM equivalent is what the market expects — send us the clause and we will tell you what it means in practice before you spend anything.
