PD ISO/TR 23605:2009 Technical product specification (TPS). Application guidance. International model for national implementation

PD ISO/TR 23605 describes the results of the inter-laboratory testing of the chemical analysis of cement by x-ray fluorescence. In the first instance, the inter-laboratory testing was carried out in Japan and in 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 loss on ignition is also determined.

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 “best practice” values representative of the ideal situation.

BS ISO 29581-2 is intended for use under everyday conditions in laboratories that operate to “good practice”. Annex D sets out the results of some international round robins carried out by a large number of laboratories demonstrating the suitability of BS ISO 29581-2 as a means for comparing the everyday performance of laboratories.
