    (What is a Work Item?)

    Active Standard: C1728 - 20b

    Developed by Subcommittee: C16.23 | Committee C16 | Contact Staff Manager



    WK66954


    Keywords

    aerogel; blanket; composite; flexible; insulation; pipe insulation; sheet; thermal conductivity; water retention;;

    Rationale

    There are three items that need to be revised in the standard: 1)Table 1: The thermal conductivity values displayed for Type III Grade 2 Category A materials have been incorrectly translated from inch-pound to SI units. The table will be corrected. 2)Sections 7.1 Maximum Use Temperature and 7.9 Maximum Exothermic Temperature Rise: Clarification on the starting test conditions for planar geometries. 3)Section 7.12 Compressive Resistance: Clarification on test conditions around allowable preloading.
