It is designed for chill-cast, rolled, and forged specimens. Work Item s – proposed revisions aztm this standard. Preparation of Specimens and Reference Materials 9.

There were no books found for the applied search filters. The specimen surface should be kept clean because the specimen is the electron emitter, and electron emission is inhibited by oily, dirty surfaces. Today, some 12, ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence.
