ASTM D256 Standard

Greetings List,

For those "materials" people out there:

   * has the ASTM D256 standard (Impact Resistance of Plastics and
     Electrical Insulating Materials) been updated since 1983?
   * is there an RP industry accepted specimen for the above
     (Charpy) test?

        * note that the 1983 standard only refers to specimens
          fabricated by moulding, compression moulding, and
          sheet products.

   * is there an RP industry accepted set of orientations for such
   * is there anything I have missed?

I will be building the above specimens on a Cubital 4600 machine (SGC),
and would be interested in others who may have done this with specimens
fabricated on other machines.

Any and all responses are deeply appreciated.

Best Regards,
