1 Foreword

JB/T 11602.1-2013 was issued by Ministry of Industry and Information Technology of the People's Republic of China on 31 December 2013 and has been in force since 1 July 2014.

It is one of 3 parts of the JB/T 11602 series.

2 Scope

This standard is the recommended Chinese machinery industry standard on the measurement and evaluation of the X-ray tube voltage of non-destructive testing instruments, and it is the part devoted to the voltage divider method. It sets out a method of direct and independent detection taken at the secondary side of the high voltage generator of constant potential, average high voltage direct current X-ray systems, the purpose being to check the corresponding high voltage value of the system. The standard is a modified adoption of BS EN 12544-1-1999, and it quotes GB/T 12604.2-2005. It is classified N78 in the Chinese system and 19.100 in the international one, and the Ministry of Industry and Information Technology issued it.
