Standards Association (CSA)
The Canadian Standards Association is one of four standards development organizations
(SDOs) accredited in Canada by the Standards Council of Canada. It is a non-profit
association with 9,000 members and more than 1,200 committees working to develop
standards nationally and globally. CSA America, Inc. is one of several groups
under the CSA umbrella. It develops standards for the United States and Canada
for appliances and accessories fuelled by natural, liquified petroleum and hydrogen
gases through more than 40 committees, sub-committees and working groups. It is
accredited by the American National Standards Institute (ANSI) and maintains approximately
80 different standards.
Its standards for food service equipment include
ranges and unit boilers, baking and roasting ovens, deep fat fryers, counter appliances,
kettles, steam cookers and steam generators.
CSA International, another group under the CSA
umbrella, is an independent and separate product testing and certification organization
and a Nationally Recognized Testing Laboratory (NRTL). CSA International absorbed
the product testing and certification program of AGA Laboratories when it acquired
ownership of International Approval Services, a joint venture of AGA and the former
Canadian Gas Association and a successor to the AGA Laboratories.
Some of the product certification marks issued
by CSA International include:
Laboratories Inc. (UL)
Underwriters Laboratories Inc., or UL as it is commonly known, is an independent,
non-profit product-safety testing and certification organization founded in 1894.
Underwriters Laboratories is a Nationally Recognized Testing Laboratory (NRTL)
whose mark means that the products it tests meet the minimum requirements of widely
accepted product safety standards and that the manufacturer agrees to periodic
follow-up inspections to verify continued compliance.
UL's testing and certification services involve
a wide variety of product categories. A Standard for Safety, criteria used by
UL as the basis for determining the eligibility of a product to bear the UL Mark,
exists for each product category.
Manufacturers submit products to UL for testing
and safety certification on a voluntary basis. There are no laws specifying that
a UL Mark must be used. However, in the U.S. there are many municipalities that
have laws, codes or regulations which require a product to be tested by a Nationally
Recognized Testing Laboratory before it can be sold in their area.
North America, UL certified products are identified by the UL Listing Mark. The
UL Listing Mark means the complete, end-use product has been tested by UL to nationally
recognized Safety Standards for fire, electric shock and casualty hazards.
also authorizes manufacturers to identify UL tested/certified components in an
end-use product with the UL Recognized Component Mark. Recognition certifies that
the designated part meets the safety requirements for a limited, specified use,
but does not attest to the safety of the end product.
third type of UL Mark is the Classification Mark. This mark appears on representative
samples of products that UL has evaluated but only with respect to specific properties,
a limited range of hazards, or suitability for use under limited or special conditions.
Products carrying the Classification Mark are typically building materials or
industrial equipment. Some examples are immersion suits, fire doors, protective
gear for fire fighters and industrial trucks.
The Blue Sanitation Mark and the EPH Product
Mark are discussed on the UL Sanitation page.
also offers a Gas-Fired Listing Mark to be used exclusively on gas-fired appliances
and equipment. The Gas-Fired Mark indicates a product's compliance to nationally
recognized gas standards and that the product has been evaluated to reasonably
foreseeable hazards including both gas and electrical hazards. Gas-Fired Equipment
that is already certified under UL standards is authorized to use the Gas-Fired
