30、plastics (GRP) component intended for use in a piping system. It includes determination of resin, glass, aggregate and filler contents.It is also applicable to the determination of the type and arrangement of the reinforcements. If used to determine the amounts of constituent materials in layered co

31、nstructions it may be necessary to separate the laminate layers by cutting or splitting and testing each separately.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

34、rn off the resin, and the residue analysed by separating and weighing the constituents loss on ignition (LOI) is a common term for such testing. If the construction includes organic reinforcements, such as surfacing veils, or processing aids, such as thermoplastic mesh or filaments, these will be bu

35、rned off with the resin. Typically such materials if used are in small amounts and will not introduce significant error in the determination of raw material contents. Also, organic materials used in glass fibre reinforcement sizing or binder will be burned off. The amounts of such materials are very

36、 small.NOTE 1 In the case of filled laminates, especially those containing fillers of small particle size (including thixotropic agents), accurate analysis of the constituents can prove difficult. This is because of the difficulty in separating such fillers from the other constituents and the risk o

37、f some filler being lost during combustion.This test method can be used to determine and monitor the fibre architecture of the laminate layers used in the piping component.NOTE 2 It is assumed that the following testing parameters are set by the referring standard:a) whether or not the types of glas

38、s fibre reinforcement in the constituent layers is to be determined;b) whether or not the glass content of each layer is to be determined; ISO 2017 All rights reserved 1BS ISO 7510:2017ISO 7510:2017(E)c) whether or not the aggregate and filler contents are to be determined, and whether to do so for

If reinforcement materials are to be classified by weight per unit area, then the test piece shall be rectangular.The recommended sample size for components up to 30 mm wall thickness is approximately 40 mm 4
