The HVCA has allied itself with four other industry organisations to promote the standardisation of circular ductwork sizes, accessories and fittings.
If the initiative is taken up all circular ductwork and accessories will be produced to conform to BS EN 1506: 1998.

The first phase of the move will lead to the discontinuation of 180, 224, 280 and 600 mm diameter products by 31 December 2002.

The organisations involved in the initiative are the HVCA, BSRIA, the Association of Ductwork Contractors and Allied Services, CIBSE and the HEVAC Association.

The move will go some way towards meeting the calls for standardisation in the Latham and Egan reports.
