News : What are the requirements of TSSA to issue a CRN?

Before a company is issued a CRN number, they are inspected by two separate departments of TSSA's Boiler and Pressure Vessels Safety Division.

1. Quality, Contract & Technical Services: A representative is sent to the applicant's premise to examine the following:
  • Quality Control Manual
  • Drawings, designs and calculations
  • Material and records control
  • Examination and inspection program
  • Correction of non-conformities
  • Calibration of equipment

2. Engineering: A TSSA inspector must witness a burst test of a sample assembly for each type of assembly to be covered under a CRN number. This is to insure that the assemblies meet the minimum safety factor, as established by the Rubber Manufacturers Assocation (RMA). The test results, hose specification and fitting specifications must be approved by a TSSA professional engineer. Any future request to add a different hose and/or type of coupling to the approved list requires a burst test and eingineering approval.
