30、ethod for the determination of constituent materials of a test sample cut from a glass-reinforced 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 arrange
31、ment of the reinforcements. If used to determine the amounts of constituent materials in layered constructions it may be necessary to separate the laminate layers by cutting or splitting and testing each separately. 2 Normative references The following documents are referred to in the text in such a

34、: available at h t t p :/ www .iso .org/ obp 4 Principle A test piece of known size and mass is ignited to burn 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 reinforce
35、ments, such as surfacing veils, or processing aids, such as thermoplastic mesh or filaments, these will be burned 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
36、used in glass fibre reinforcement sizing or binder will be burned off. The amounts of such materials are very 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 diff
37、icult. This is because of the difficulty in separating such fillers from the other constituents and the risk of 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 ass
38、umed that the following testing parameters are set by the referring standard: a) whether or not the types of glass 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 1 BS ISO 7510:2017
39、 ISO 7510:2017(E) c) whether or not the aggregate and filler contents are to be determined, and whether to do so for each layer. This document is used to measure and describe the behaviour of composite material to heat under controlled conditions, but does not by itself incorporate all the factors r
40、equired for fire hazard or fire assessments of the composite materials under actual fire conditions. Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests. This document does not purport to address all of the safety concerns,
41、 if any, associated with its use. It is the responsibility of the user to consult and establish appropriate safety and health practices in accordance with national regulations prior to use. This test method does not apply to constructions that contain reinforcement materials that lose weight under t
42、he conditions of test or contain resins that do not decompose. The content of fillers that decompose under the conditions of test cannot be determined by this method and alternate procedures shall be employed. 5 Apparatus The usual laboratory apparatus and, in particular, the following. 5.1 Crucible

44、lar. 5.5 Desiccator. 5.6 Balance, calibrated to an accuracy of 1 mg. 5.7 Measuring devices calibrated to an accuracy of 0,05 mm. 5.8 Sieves, of suitable mesh, as needed to separate fillers and aggregate. 5.9 Spatulas, tweezers and sieves, as needed to separate constituent materials. 6 Test piece 6.1
45、 Dimensions The test piece shall comprise the full thickness of the component from which the test piece was taken, unless individual layers are being investigated. The test piece shall have smooth edges and be free from dust. If reinforcement materials are to be classified by weight per unit area, t
46、hen the test piece shall be rectangular. The recommended sample size for components up to 30 mm wall thickness is approximately 40 mm 40 mm multiplied by the thickness of the component. For components with a wall thickness exceeding 30 mm, samples of approximately 40 mm 10 mm multiplied by the thick
47、ness of the component have been found acceptable. Other sample sizes are permitted by agreement.
