6、EN/TC 286. A minor discrepancy in ISO 15995:2006 was not discovered until CEN decided to adopted that standard unchanged. In 5.3.1, Table 1, the test temperature for test no. 16 is given as 65 (/2,5) C, while in 5.19 this temperature is given as 65 C, without a tolerance. The above-mentioned tempera

7、ture with the tolerance is to be taken.
