In the first instance, the inter-laboratory testing was carried out in Japan and Asian countries 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 the same materials in 2005 in accordance with EN 196-2, a development by CEN\/TC 51\/WG 15\/TG 1 of JIS R 5204. The latest version, developed as ISO 29581-2, is, as of the date of publication of this Technical Report, in the process of being circulated for technical enquiry.<\/p>\n<p>The test samples used were Portland cement conforming to CEM I of EN 197-1 and a mixture of Portland cement and blast furnace slag. The mixture corresponded to the composition of Portland blast furnace slag cement, class B, specified in JIS R 5211 and CEM III\/A of EN 197-1. Cement reference materials for x-ray fluorescence analysis (No. 601A) are used for the calibration standards, and certified reference materials JCA-CRM-1 and JCA-CRM-2 are used as the validation materials.<\/p>\n<p>Constituents analysed include SiO<sub>2<\/sub>, Al<sub>2<\/sub>O<sub>3<\/sub>, Fe<sub>2<\/sub>O<sub>3<\/sub>, CaO, MgO, SO<sub>3<\/sub>, Na<sub>2<\/sub>O, K<sub>2<\/sub>O, TiO<sub>2<\/sub>, P<sub>2<\/sub>O<sub>5<\/sub>, MnO and SrO. The loss on ignition is also determined.<\/p>\n<p>The ISO round robin is a method-performance study conducted under close to optimum conditions with clear calibration and measurement guidelines. This is conducive to producing \u201cbest practice\u201d values representative of the ideal situation. However, ISO 29581-2 is intended for use under everyday conditions in laboratories that operate to \u201cgood practice\u201d. The results are presented for some international round robins carried out by a large number of laboratories demonstrating the suitability of ISO 29581-2 as a means for comparing the everyday performance of laboratories.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Methods of testing cement \u2014 Report of a test programme \u2014 Chemical analysis by x-ray fluorescence<\/b><\/p>\n<table style=\"width: 100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td>Published By<\/td>\n<td>Publication Date<\/td>\n<td>Number of Pages<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pdfstandards.shop\/product-category\/publishers\/iso\/\"><b>ISO<\/b><\/a><\/td>\n<td>2009-05<\/td>\n<td>60<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":639108,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[1254,2634],"product_tag":[],"class_list":{"0":"post-639094","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-91-100-10","7":"product_cat-iso","9":"first","10":"instock","11":"sold-individually","12":"shipping-taxable","13":"purchasable","14":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/639094","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media\/639108"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=639094"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=639094"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=639094"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
