1 Foreword

JB/T 4279.12-2008 was issued by Ministry of Industry and Information Technology of the People's Republic of China on 1 February 2008 and has been in force since 1 July 2008.

It replaces the earlier edition JB/T 4279.12-1994.

It is one of 29 parts of the JB/T 4279 series.

2 Scope

Low-voltage checking of the continuity of the enamel film is the subject of JB/T 4279.12-2008, Part 12 of the recommended Chinese machinery industry standard on verification procedures for test equipment of enamelled winding wire. It fixes the items to be verified on the low-voltage film continuity tester and the technical requirements for them, names the apparatus used in the verification, prescribes the test methods, and states how the results are treated. The wire concerned is enamelled round wire. Filed under the Chinese classification K12 and the international classification 29.060, the document was issued by the Ministry of Industry and Information Technology. It quotes JB/T 4279.1-2008 and replaces JB/T 4279.12-1994.
