• What requires a CRN registration?

  Pressure equipment, including pressure vessels, boilers, piping and fittings, used in Canada requires a CRN registration. Equipment must be registered with a CRN before it is used. In general, if pressure equipment operates at a pressure greater than 15 PSIG it will likely require a CRN registration. In fact, unless a particular exemption applies to the equipment, a Canadian Registration Number is needed. Keep in mind, provincial and territorial governments have the authority to govern equipment safety in their region. Therefore, CRN registration requirements vary by province and territory. As a result, CRN exemptions are set out by provincial and territorial governments. Read More...

• Do I need a CRN number?

  Will your pressure equipment operate at 15 psig or higher? If so, you will likely need a CRN number and, sometimes, even though contained pressures are less than 15 psig, exemptions do not apply. In most cases, pressure equipment in Canada requires a Canadian Registration Number (CRN). That is, unless CRN exemptions apply to your equipment. CRN exemptions vary from province to province. Therefore, you will need to check the codes and regulations specific to the province or territory in which your pressure equipment is to be used. If you need a CRN number for your equipment, it must be obtained before the pressure equipment is pressurized. If you require assistance in determining whether your equipment needs a CRN number,  CAMMAR Corporation can help. Read More...

• When should I apply for a CRN?

  If your equipment requires a Canadian Registration Number, you must apply for the CRN before the pressure equipment can be installed and used in Canada. In fact, it is wise to complete your CRN registration before the pressure equipment is in the final stages of design (i.e. before the equipment is built). This will ensure that you follow CSA B51 and other regulations without issue. In any case, to avoid unnecessary complications, make sure that your CRN registration is completed before any assembled equipment leaves the producer. If the equipment will not be assembled until after it leaves the manufacturer (e.g. the equipment must be assembled in the field), be sure the design has a Canadian Registration Number. Read More...

• How do I get a CRN number?

  Though you can apply to get a CRN number by documenting your CRN design and submitting the appropriate application forms to the regulator in the province or territory where the equipment will be used, regulators can simply reject your CRN design registration application if they are not satisfied that the design meets the requirements of the jurisdictional regulations, adopted codes, and referenced standards. And, ... though regulators must tell you why a design doesn't meet their requirements, they cannot tell you how to fix a deficient CRN design, since that would put them in a conflicted position.  Afterall, they can't properly accept a CRN design that incorporates their own advice.  Though regulators control the CRN registration process, they are not supposed to be, and cannot be, owners. Each province and territory has rules in its jurisdiction, which must be met.  If some jurisdictions have tougher requirements than others, it's thereby best to apply to the toughest jurisdiction first.  For more about how and why to get a CRN, read this. Alternatively, CAMMAR can assist you directly pursuant to getting a CRN. registration. Read More...

• Why are CRNs required?

  CRNs, or Canadian Registration Numbers, are required in Canada to ensure public safety. A CRN number Canada helps to guarantee that pressure equipment meets adequate safety requirements. Equipment must be designed, built and tested based on codes and standards that have been developed to protect the public. As well, provincial and territorial governments in Canada use CRNs to assign responsibility for pressure equipment designs. Although each province and territory has authority over registration and requirements in their own region, regulatory bodies work together to ensure that CRNs are recognizable and can be tracked across the country. A CRN is required before the pressure equipment is built. Read More...

• What is a CRN?
