This document specifies three methods for the determination of ash from raw rubbers, compounded rubbers and vulcanizates. The methods are applicable to raw, compounded or vulcanized rubbers of the M, N, O, R and U families described in ISO 1629, except that:

— Method A is not used for the determination of ash from compounded or vulcanized rubbers containing chlorine, bromine or iodine;

— Method B is used for compounded or vulcanized rubbers containing chlorine, bromine or iodine. It shall not be used for uncompounded rubbers;

— Method C is intended to be used for the determination of ash from raw, compounded or vulcanized rubber not containing chlorine, bromine or iodine by wrapping the test portion in ashless filter paper;

— Lithium and fluorine compounds might react with silica crucibles to form volatile compounds, giving low ash results. Platinum crucibles shall therefore be used for ashing fluorine-containing and lithium-polymerized rubbers.

This document does not cover the interpretation of the ash results as to the inorganic chemical content of a compound or vulcanizate. This is the responsibility of the analyst, who has to be aware of the behaviour of rubber additives at elevated temperatures.

This document covers the following aspects of fire testing of plastics materials and products: -

— Selection of appropriate tests that reflect realistic end-use conditions

— Grouping of the reaction-to-fire characteristics that any given test or tests can measure

— Assessment of tests as to their relevance in areas such as material characterisation, quality control, preselection,

end-product testing, environmental profiling and DfE (Design for the Environment)

— Definition of potential problems that may arise when plastics are tested in standard fire tests

This document does not include specification for development or design of new fire-tests for plastics.

However, the flexibility of approach that is indicated with respect to the mounting and fixing of test

specimens is valuable when fire testing laboratories and certification bodies are considering how to evaluate

ranges of plastics that are used in different ways.

This document covers the determination of the characteristic load resistance Fp and the characteristic plate stiffness kp of plate anchors. 

This document gives information on the applicability of general test methods for coatings on plastics, plastics composites and similar substrates, hereinafter collectively referred to under the term "plastics". It provides a general introduction to the particularities of coatings on plastics and specifies general terms and definitions.

This document gives an overview on the weathering and radiation testing of coatings on plastics, plastics composites and similar substrates, hereinafter shortly referred to as plastics. Characteristics and differences to metallic substrates of plastics are explained, as well as their effect on the behaviour of the coating during the weathering test.

This document gives an overview on the constant climate and alternating climate tests of coatings on plastics, plastics composites and similar substrates, hereinafter shortly referred to as plastics. Characteristics of plastics and differences to metallic substrates are explained, as well as their effect on the behaviour of the coating during the climate tests.

This document gives an overview on the abrasion and scratch tests of coatings on plastics, plastics composites, and similar substrates, hereinafter collectively referred to under the term plastics. Characteristics and differences to metallic substrates of plastics are explained, as well as their effect on the behaviour of the coating during the abrasion and scratch tests is taken into consideration.

This document gives an overview on chemical tests on the coatings of plastics, plastics composites and similar substrates. Chemical resistance is normally a surface test, nevertheless the substrate has an influence and is also considered.

This document gives an overview on the testing of the stone-chip resistance of coatings on plastics, plastics composites and similar substrates. Stone-chip resistance is usually assessed through surface tests, but nonetheless the substrate has an influence and is considered.

This document provides guidelines for selecting the measuring device, measuring geometry and temperature control unit. The general principles of test performance are described, and example evaluations of rotational and oscillatory rheometry are provided.
