(What is a Work Item? / How to Input to a Work Item)

Work Item: ASTM WK20409 - Revision of C1248 - 08 Standard Test Method for Staining of Porous Substrate by Joint Sealants


Active Standard: C1248 - 08(2012)

Developed by Subcommittee: C24.40 | Committee C24 Home | Contact Staff Manager



1. Rationale

We are attempting to update the Precision and Bias statement to reflect consistency across several laboratories and also among separately sourced samples of Vermont Marble (or other substrates to be determined).It is hoped that we will be able to establish a basis for testing a sealants innate tendency to stain porous substrates in this way.
