International Organization for Standardization published the third edition of ISO 13528 Statistical methods for use in proficiency testing by interlaboratory comparison that cancels and replaces the second edition (ISO 13528:2015), effective date from September 01, 2022. The international standard ISO 13528 is one of the main reference documents in the ISO/IEC 17043 Conformity assessment — General requirements for proficiency testing, approved in Russian Federation as an interstate standard GOST ISO/ IEC 17043-2013.

— notes have been added to 10.1, 10.4.3 and 10.5.3 to draw attention to additional graphical techniques that can assist in meeting the provisions of 10.1;

— Formulae B.4 and B.8 have been corrected to use st2 instead of wt2;

— Formula B.16 has been corrected so that the term inside the square root is always non-negative;

— in Table C.2, the correction factor associated with p = 2 has been corrected to read 0,3994;

— additional literature references to the source of values in Table C.2 have been added to the Bibliography and referenced from Notes 1 and 2 of C.5.2.1;

— font styles (Italic or Roman) have been amended throughout for consistency in formulae.

We draw the attention of proficiency testing providers to the fact that in the Russian Federation the national standard is GOST R 50779.60-2017 Statistical methods. Application for proficiency testing through interlaboratory testing, which is based on the modified second edition of ISO 13528 not third, and therefore we recommend that you implement the third edition of ISO 13528:2022 in order to take into account the corrections as soon as possible.
