DIN EN ISO 11358-1:2014-10

This International Standard specifies general conditions for the analysis of polymers using thermogravimetric techniques. It is applicable to liquids and solids. Solid materials may be in the form of pellets, granules or powders. Fabricated shapes reduced to appropriate specimen size may also be analysed by this method. This document (EN ISO 11358-1:2014) has been prepared by Technical Committee ISO/TC 61 "Plastics" (secretariat: SAC, China) in collaboration with Technical Committee CEN/TC 249 "Plastics", the secretariat of which is held by NBN, Belgium. The responsible German body is NA 054-01-03 AA "Physikalische, rheologische und analytische Prüfungen" ("Physical, rheological and analytical test methods") at DIN Standards Committee Plastics (FNK). Under the general title "Plastics - Thermogravimetry (TG) of polymers" ISO 11358 consists of the following parts: - Part 1: General principles - Part 2: Determination of kinetic parameters - Part 3: Determination of the activation energy using the Friedman plot and preparation of master plots for validation of reaction kinetic analysis. Compared to DIN EN ISO 11358:1997-11 the following modifications have been made: ISO 472 included in the normative references and the terms specified there have been deleted and the apparatus specifications have been revised.
