ASTM WK33605

    Work Item: ASTM WK33605 - Revision of C920 - 11 Standard Specification for Elastomeric Joint Sealants

    (What is a Work Item?)

    Active Standard: C920 - 14

    Developed by Subcommittee: C24.10 | Committee C24 | Contact Staff Manager



    1. Rationale

    To correct an error in C920. In both paragraphs 4.1.10 and 4.1.11, modulus is conflated with hardness; they are not the same thing. Corrected wording is below: 4.1.10 Use T1A sealant designed for use in joints in pedestrian and vehicular traffic areas such as walkways, plazas, decks and parking garages where a higher modulus hardness, firmer sealant is desired. 4.1.11 Use T2A sealant designed for use in joints in pedestrian and vehicular traffic areas such as walkways, plazas, decks and parking garages where a more lower modulus hardness, softer sealant is desired.
