Solid recovered fuels - Determination of self-heating - Part 2: Basket heating tests (ISO/TS 21911-2:2022)
This document gives guidance on basket heating tests for characterization of self-heating properties of solid recovered fuels (SRFs).
This document includes:
a) a compilation of basket heating test methods;
b) guidance on the applicability and use of basket heating tests for SRF;
c) information on the application of basket heating test data for calculations of critical conditions in storage.
Data on spontaneous heat generation determined using this document is only associated with the specific quality and age of the sample material.
The information derived using this document is intended for use in quality control and in hazard and risk assessments related to the procedures given in ISO 21912.

This Technical Specification (CEN/TS) was approved by CEN on 3 July 2022 for provisional application.
The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to
submit their comments, particularly on the question whether the CEN/TS can be converted into a European Standard.
CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS
available promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in
parallel to the CEN/TS) until the final decision about the possible conversion of the CEN/TS into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,
Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and
