CRN (Canadian Registration Number) is required in all provinces and territories (jurisdictions) throughout Canada where the pressure vessel will be operated. The system is governed by the general CSA B 51 standard, but every province or territory can add their own specific rules to make the standard enforceable. A CRN number will be required for each jurisdiction where the pressure vessel will be operated. CRN does reference many ASME codes, however the B51 standard adds many additional rules and is specific to Canada. ASME alone is not sufficient to legally and safely operate a pressure vessel system within Canada.

ASME Boiler & Pressure Vessel Code (BPVC) is an American Society of Mechanical Engineers (ASME) standard that regulates the design and construction of boilers and pressure vessels. Many countries around the world require this standard.

Pressure Equipment Directive (PED) 2014/68/EU of the European Union sets out the standards for the design and fabrication of pressure equipment. PED also lays out administrative procedure requirements for a conformity assessment, allowing for free placing in the European market without any added local legislative requirements. PED has been mandatory throughout the EU since 30 May 2002.

CSA International (Canadian Standards Association), a member of the CSA Group, is a provider of product testing and certification services for electrical, mechanical, plumbing, gas and a variety of ot her products. Recognized in the U.S., Canada and around the world, CSA’s marks appear on billions of products worldwide. Electrical equipment used in electrical installations within the jurisdiction of the inspection department shall be approved and shall be of a kind or type and rating approved for the specific purpose for which it is to be employed. CSA International certification marks indicate that a product, process or service has been tested to a Canadian or U.S. standard and it meets the requirements of an applicable CSA standard or another recognized document used as a basis for certification.

Pressure Safety Inspectors (PSI) offers third party independent design verification (otherwise referred to as an engineering peer review) of extraction equipment. PSI has performed reviews for over tw o dozen original equipment manufacturers (OEMs), and has developed internal procedures that provide the most comprehensive engineering peer review available for extraction equipment. Our reports are sealed by engineers licensed in California, Colorado, Maryland, Nevada, Oregon, Pennsylvania, and Washington.
