BRA revises brazing guidance
26th November 2014UK: The British Refrigeration Association (BRA) has revised its refrigeration pipework brazing specification.
This latest Issue 5 contains a BRA recommendation section to cover vertical upflow test joints which are not currently fully covered in BS EN14276. The new section covering the vertical upflow test joints is as required by BS EN13585 and it was considered important that this be included so that training covers all required aspects. The BRA recommendation now covers this aspect until such time that BS EN 14276 is amended.
The specification Jointing of Copper Pipework for Refrigeration Systems Specification & Procedures for Manual Torch Brazing and Brazer Assessment was developed by the BRA Commercial Contractors Section. It also incorporates a practical means of assessing an individual’s competence to braze joints for refrigeration and air conditioning pipework in accordance with national standards and relevant legislation.
The BRA has been busy producing guidance in the last twelve months and their informative Fact Finders offer valuable information for the sector. The following are the most recent:
Fact Finder 7 – A Guide to Selecting Copper Tube and Fittings for Refrigeration & Air Conditioning Systems with Air Cooled Condensers. Completely updated to be in line with BS EN14276.
Fact Finder 17 – Using Refrigerant GWP Values – A guide to selecting the appropriate data. Also completely updated to reflect the latest GWP values that will be referred to under the new F-gas regulation.
Fact Finder 19 – BRA Recommendation for Specification of Natural Refrigerants. A new Fact Finder covering ammonia (R717/NH3), hydrocarbons (R600a/isobutane, R290/propane, R1270/propylene, etc) and carbon dioxide (R744/CO2).
