It is a discussion going on in Europe about Specification AMS 2431/6 Glass Shot.
It is well known that several manufacturers supply beads according to this specification. The questuion is do they perfome all the required tests on each lot?
Is hardness for example tested on each lot and is it necessary?

Chris Davies of Potters tells me that the specification is being modified to make many of the tests periodic instead of every lot. You may e-mail him at [email protected]
