This document covers the following aspects of fire testing of plastics materials and products: - 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 specifies a fire test method for assessing the fire performance of water-filled plastic pipes and fibre reinforced plastic (FRP) pipes. This document provides a fire test method to be conducted in light of the application of IMO Assembly resolution A.753(18)[1]the Guidelines for the application of plastic pipes on Ships, as amended.

 

This document specifies a general information model for provenance of biological material. The requirements defined here are applicable to organizations, authorities and industries carrying out or being involved in activities related to biological material, generating, collecting, analyzing or storing data on biological material, manufacturing devices or software for the aforementioned tasks, or providing facilities for these tasks. This standard defines a provenance information model suitable for describing source material, from which the sample originates, and all steps in its life cycle from acquisition, transport, and processing to storage and disposal. The biological material can be from multicellular organisms (e.g. human, animal, fungus and plant), microorganisms, or environmental samples.

 

This document provides guidnce 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 provides guidance 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 provides guidance 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 provides guidance 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 specifies an accelerated method for the determination of wet-scrub resistance. The determination of cleanability is not covered in the scope of this document.

 

This document provides guidance 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.

 

The ability of coatings to withstand wear caused by repeated cleaning operations and to withstand penetration by soiling agents is an important consideration both from a practical point of view and when comparing and rating such coatings. ISO 11998:2006 describes an accelerated method for the determination of wet-scrub resistance. With regard to the cleanability of coatings, only the method itself and not the soiling agents are specified.

 

The oil absorption value is required to be compared with the value determined at the same time on an agreed sample of the product. The principle of the method is based on addition of linseed oil from a burette to the test portion. After each addition, rub the oil into the product until conglomerates are formed. Cease the addition of oil when a paste of smooth consistency has been formed. It should just spread without cracking or crumbling. Read the burette and note the quantity of oil used. The result is expressed in millilitres of oil per 100 g of product or in grams of oil per 100 g of product. - Cancels and replaces Part 5 of ISO/R 787-1968.

 

The method specified provide an instrumental alternative to those described in ISO 787/16 and ISO 787/17. Equal masses of a coloured material are separately dispersed in the same mass of the same white pigment paste. The reflectivity of each dispersion is measured photometrically. From the corresponding values of K/S the relative tinting strength is given. For measurement of the relative scattering power equal masses of a white test material and an agreed reference pigment are separately dispersed in the same mass of the same black pigment paste. The reflectivity of each dispersion is measured photometrically at 550 nm. From the corresponding values of K/S the relative scattering power is given.

 

This document specifies a method for determining the film thickness of a coating on concrete substrate by cross-section method. Coatings of various types shall meet the respective technical requirements. Furthermore, physical properties depend strongly on the film thickness. Hence, the knowledge of the film thickness in a coating system is important for the product development as well as for the application and evaluation of claims. Determining the film thickness of systems filled with quartz sand can be particularly difficult. This document describes the method for a measurement of film thickness in cured flooring system build-ups.

 

This document specifies photometric methods of test for comparing in the visible spectrum This document is not appropriate for the comparison of coloured pigments that on reduction differ greatly in colour.

 

This document specifies a general method of test for determining the oil absorption value of a sample of pigment or extender. The oil absorption value is usually required to be compared with the value determined at the same time on an agreed sample of the product.
