Scope 1.1 This procedure defines the long-term thermal resistance (LTTR) of a foam product as the value measured after 5-year storage in a laboratory environment and provides means for its prediction based on an accelerated laboratory test. 1.2 This procedure, based on ASTM standard test methods ASTM C1303 and ASTM C518, can be applied to a wide range of preformed as well as field…

This document specifies graphical symbols for diagrams related to industrial components, products and processing. This document constitutes a symbol library, from which users can use the symbols or created symbol examples for use in diagrams (see Tables 1 to 149). General rules and guidance for the preparation and presentation of graphical symbols are given in ISO 14617-1. Application rules for…
