This Technical Report describes the results of the inter-laboratory testing of the chemical analysis of cementby x-ray fluorescence. In the first instance, the inter-laboratory testing was carried out in Japan and in Asiancountries in accordance with JIS R 5204:2002. A total of 30 laboratories, 16 in Japan and 14 outside Japan,participated in the original testing programme. A further 12 European laboratories participated in tests with thesame materials in 2005 in accordance with EN 196-2, a development by CEN/TC 51/WG 15/TG 1 ofJIS R 5204. The latest version, developed as ISO 29581-2, is, as of the date of publication of this TechnicalReport, in the process of being circulated for technical enquiry.The test samples used were Portland cement conforming to CEM I of EN 197-1 and a mixture of Portlandcement and blast furnace slag. The mixture corresponded to the composition of Portland blast furnace slagcement, class B, specified in JIS R 5211 and CEM III/A of EN 197-1. Cement reference materials for x-rayfluorescence analysis (No. 601A) are used for the calibration standards, and certified reference materialsJCA-CRM-1 and JCA-CRM-2 are used as the validation materials.Constituents analysed include SiO2, Al2O3, Fe2O3, CaO, MgO, SO3, Na2O, K2O, TiO2, P2O5, MnO and SrO.The loss on ignition is also determined.The ISO round robin is a method-performance study conducted under close to optimum conditions with clearcalibration and measurement guidelines. This is conducive to producing “best practice” values representativeof the ideal situation. However, ISO 29581-2 is intended for use under everyday conditions in laboratories thatoperate to “good practice”. Annex D sets out the results of some international round robins carried out by alarge number of laboratories demonstrating the suitability of ISO 29581-2 as a means for comparing theeveryday performance of laboratories.
