    1. Rationale

    The current standard is due for re-approval in 2013. The designation of the NBR-L elastomer has changed from 2B to 2C and the narrative and tables need updating to reflect this. It was voted in B.04 to make these changes and submit for re-approval. The revisions in D4289 have been approved nem con and now the concomitant changes to D4950 need to be balloted
