UK: The BRA’s commercial contractors section has developed a simple brazing procedure specification and approval for jointing copper pipework for refrigeration systems.
This update of Jointing of Copper Pipework for Refrigeration Systems – Specification & Procedures for Manual Torch Brazing and Brazer Assessment recognises the importance of brazed joints in maintaining the effective and efficient operation of refrigeration and air conditioning systems. The specification also incorporates a practical means of assessing an individual’s competence to braze joints in accordance with national standards and relevant legislation.
This revision has incorporated high strength copper alloy pipe in recognition of is adoption on R744 systems and is also applicable to A2L refrigerants.
