6、 CEN/TC 286. A minor discrepancy in ISO 14245:2006 was not discovered until CEN decided to adopted that standard unchanged. In Clause 2, Table 1, the test temperature for test no. 16 is given as 65 (/2,5) C, while in 5.18 this temperature is given as 65 C (/5) C. The first-mentioned tolerance (/2,5)
7、 C is to be taken. The DIN Standards corresponding to the International Standards referred to in this document are as follows: ISO 11114-1 DIN EN ISO 11114-1 ISO 11114-2 DIN EN ISO 11114-2 ISO 11116-1 DIN EN ISO 11116-1 ISO 10920 and ISO 11116-1 have been replaced by ISO 11363-1 which has been taken
8、 over as DIN EN ISO 11363-1. Amendments This standard differs from DIN EN 13152:2003-09 as follows: a) the standard has been brought in line with the current rules of presentation; b) normative references have been updated; c) terms and definitions have been expanded and given in more detail.
