This document specifies a method for the determination of the mass concentration (µg/g) of tyre and road wear particles (TRWP) in soil or sediment environmental samples. This document establishes principles for soil or sediment sample collection, the generation of pyrolysis fragments from the sample, and the quantification of the generated polymer fragments. The quantified polymer mass is used to calculate the concentration of TRWP in soil or sediment. These quantities are expressed on a TRWP basis, which includes the mass of tyre tread and mass of road wear encrustations, and can also be expressed on a tyre rubber polymer or tyre tread basis.

 

 

This document specifies a general concept for provenance information of biological material and data, organizational roles, and requirements for provenance information management. The provenance information covers any information relevant to the traceability, quality and fitness for purpose of the biological material and data generated throughout the life cycle of the biological material from collection to analysis, including data originating from analytical procedures applied to the biological material and further processing of the data. This document is applicable to organizations, authorities and industries that are: This document is also applicable to providers of services related to provenance information management (e.g., provenance information generation, storage, provision, or validation). Customers, regulatory authorities, organizations and schemes using peer-assessment, accreditation bodies, and others can use this document in confirming or recognizing the competence of the aforementioned parties. This document does not apply to biological material and data used for medical diagnosis, treatment and therapy.

 

This document specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of acrylonitrile-butadiene-styrene (ABS) moulding and extrusion materials. Requirements for handling the test material and for conditioning both the test material before moulding and the specimens before testing are given. Procedures and conditions for the preparation of test specimens and procedures for measuring properties of the materials from which these specimens are made are given. Properties and test methods which are suitable and necessary to characterize ABS moulding and extrusion materials are listed. The properties have been selected from the general test methods in ISO 10350-1. Other test methods in wide use for, or of particular significance to, these moulding and extrusion materials are also included in this document, as are the designatory properties specified in ISO 19062-1. In order to obtain reproducible and comparable test results, it is intended to use the methods of specimen preparation and conditioning, the specimen dimensions and the test procedures specified in this document. Values determined will not necessarily be identical to those obtained using specimens of different dimensions or prepared using different procedures.

ISO 877-3:2018 specifies a method for exposing plastics to concentrated solar radiation using reflecting concentrators to accelerate the weathering processes. The purpose is to assess property changes produced after specified stages of such exposures. The reflecting concentrators used in these exposures are sometimes referred to as "Fresnel reflectors" because in cross-section the array of mirrors used to concentrate the solar radiation resembles the cross-section of a Fresnel lens. General guidance concerning the scope of the ISO 877 series is given in ISO 877-1. NOTE Additional information about solar concentrating exposures, including a partial list of standards in which they are specified, is given in the Bibliography.

 

This document specifies a method for the determination of the thermal stability at elevated temperature of compounds and products based on vinyl chloride homopolymers and copolymers (in the following text abbreviated as PVC) which undergo dehydrochlorination (the evolution of hydrogen chloride). This document is applicable to the characterization of PVC compounds and products, especially with regard to the effectiveness of their heat-stabilizing systems. It is applicable to coloured PVC compounds and products where a discolouration test under the action of heat may be unsatisfactory. This document is applicable to compounded PVC materials and products. It can be applicable to polymers in powder form under appropriate conditions, to be agreed upon between the interested parties. This document does not apply to PVC compounds in the form of dry blends, since such materials can be not sufficiently homogeneous. This document does not apply to PVC compounds and products which evolve other decomposition products, in addition to hydrogen chloride, at elevated temperatures that can affect the conductivity of water when they are absorbed into it. In this case, a method suitable for the determination of chloride ion (Cl-) in the absorbing solution shall be used (see ISO 182-4[2]). This document can also be applied to other plastics materials which can evolve hydrogen chloride or other hydrogen halides when heated under the conditions prescribed by the relevant specifications, or as agreed upon between the interested parties.
