News : Who is TSSA and what are CRNs?

TSSA is the Technical Standards and Safety Authority. They are an independent, non-government, non-profit organization. The Boiler and Pressure Vessels Safety Division of TSSA is responsible for the regulation of boilers, pressure vessels, pressure piping, fittings and hose assemblies as outlined under the CSA B51-97: Boiler, Pressure Vessel and Pressure Piping Code. Each province of Canada has a similar regulating body.

CRN stands for Canadian Registration Number. This is a number issued by TSSA to a company signifying that the hose assemblies produced by that company comply with the requirements of TSSA. The CRN number is either engraved on one of the fittings of the hose assembly or appears on a metal tag attached to the hose assembly.
