Provides detailed requirements for the production of a 50 W nominal, pre-mixed type test flame. The approximate overall height is 20 mm. The main changes with respect to the previous edition are described below:- The introduction has been revised, - Test methods B and C have been withdrawn. Test method A has been retained with its original letter designation, - Normative reference ISO 1337 has been withdrawn without a replacement by ISO/TC 26. The callout Cu-ETP UNS 11000 is the replacement for all references to ISO 1337. It is taken from ASTM B187-00 and describes high conductivity electrolytic copper, - A new Annex H has been added which provides access to equipment manufacturers and suppliers, - Alignment with other publications in the IEC 60695-11 series has been made, where appropriateHas the status of a basic safety publication in accordance with IEC Guide 104.
