Certification Marks

These are the certification marks you will find for certified foodservice equipment that adhere to a wide range of regional, national and international standards, including standards written or administered by the American National Standards Institute (ANSI), Underwriters Laboratories (UL), Canadian Standards Association (CSA), National Sanitation Foundation (NSF), Air-Conditioning and Refrigeration Institute (ARI) and Energy Star. 

NSF Mark The presence of the NSF mark on food service equipment means that the equipment has been evaluated, tested, and certified by NSF International as meeting international commercial food equipment standards. As part of the certification process, the production facility is audited annually. The purpose of this audit is to assure that all the requirements of the standard continue to be met, quality assurance and quality control procedures are followed in fabrication, products are sampled and retested on schedule, and labeling and product literature are true and accurate.

NSF Canadian Mark The cNSFus mark attests that a product has been certified to both Canadian and U.S. requirements. NSF's certification programs are accredited by the Standards Council of Canada (SCC) as meeting the requirements that demonstrate NSF's ability to certify products against applicable Canadian standards.

UL Mark The UL Listing mark means that UL found that representative samples of this product met UL's safety requirements. These requirements are primarily based on UL's own published Standards for Safety.

C-UL Listing Mark The C-UL Listing mark is applied to products for the Canadian market. The products with this type of mark have been evaluated to Canadian safety requirements, which may be somewhat different from U.S. safety requirements.

C-UL US Listing Mark UL introduced the C-UL US Listing mark in early 1998 to indicate compliance with both Canadian and U.S. requirements.

UL Gas Fired Mark The UL Gas-Fired Listing mark is used exclusively on gas-fired appliances and equipment. The Gas-Fired mark indicates a product's compliance to nationally recognized gas standards, including UL, ANSI Z21/Z83 Series and CSA/CGA standards. The Gas-Fired mark signals that a product has been evaluated to reasonably foreseeable hazards including both gas and electrical hazards.

UL Gas Fired Canadian Mark Gas-fired equipment evaluated to Canadian National Standards is authorized to display the Canadian Gas-Fired mark.

UL Gas Fired Canadian & US Mark For gas-fired equipment evaluated to both U.S. and Canadian Standards, the combination U.S. and Canadian mark will be authorized for use.

UL EPH Mark The UL EPH mark appear on products that have been evaluated to Environmental and Public Health Standards. The "Classified" version is used for products complying with ANSI/NSF Standards and other food equipment hygiene codes and requirements. Examples include Food Service and Meat and Poultry Plant Equipment and Drinking Water Additives.

UL EPH Listed Mark The UL EPH Listed version is typically used for products complying with UL's own published EPH Standards for Safety.

UL Food Service Product Certification mark The UL Food Service Product Certification mark appears on food service equipment that UL has evaluated for sanitation hazards. This type of equipment includes gas and electrically powered food service products as well as items without a power source such as plastics. These products are commonly found in commercial food establishments, institutional food services and other locations.

How do products earn the CSA certification mark?
To earn the CSA certification mark, the manufacturer submits appropriate technical documentation and a prototype of the product to CSA International. The product is then tested to determine whether it meets specific standards that apply to that type of product in the market in which it is intended to be sold. For example, electrical appliances are tested to a different set of standards than gas appliances. Although the requirements vary for different types of products, the goal is basically the same - to help ensure that the product complies with the local codes and regulations. Production facilities are inspected regularly to ensure that they continue to comply with the standards. 

CSA Mark CSA mark on its own, without indicators, means that the product is certified primarily for the Canadian market, to the applicable Canadian standards. If a product has features from more than one area, (e.g. electrical equipment with fuel burning features), the mark indicates compliance to all applicable Standards.

CSA mark with the indicator "US" or "NRTL" means that the product is certified for the U.S. market to the applicable U.S. standards. If a product has features from more than one area, (e.g.. electrical equipment with fuel burning features), the mark indicates compliance to all applicable Standards.

CSA Canadian & US Mark
CSA Canadian & US Mark
CSA mark with the indicators "C" and "US" or "NRTL/C"means that the product is certified for both the U.S. and Canadian markets, to the applicable American and Canadian standards. If a product has features from more than one area, (e.g.. electrical equipment with fuel burning features), the mark indicates compliance to all applicable Standards.

CSA Canadian & US Mark A product bearing the ETL Listed mark is determined to have met the minimum requirements of prescribed product safety standards. The mark also indicates that the manufacturer's production site conforms to a range of compliance measures and is subject to periodic follow-up inspections to verify continued conformance. ETL Listed mark is used on electrical, gas, and oil fired products. The ETL Listed mark is the legal equivalent of the UL Listed and CSA Listed Marks throughout the United States and Canada.

ETL Listed Mark A product bearing the ETL Listed mark with the "US" identifier at the 4 o'clock position has been tested and deemed compliant to U.S. product safety standards only. An ETL Listed mark with a "C" identifier at the 8 o'clock position means the product bearing it complies with Canadian product safety standards only. And an ETL Listed mark with both "US" and "C" identifiers at the 4 o'clock and 8 o'clock positions respectively, signifies that the product bearing the mark complies with both U.S. and Canadian product safety standards.

Energy Star logo ENERGY STAR is a joint agency program supported by Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE) that offers businesses and consumers energy-efficient solutions, making it easy to save money while protecting the environment for future generations.

ISO 9000 is a family of standards for quality management systems maintained by the International Organization for Standardization (IS0), and is administered by accreditation and certification bodies. 

ISO Mark ISO 9001:2000 Quality management systems is intended for use in any organization which designs, develops, manufactures, installs and/or services any product or provides any form of service. It provides a number of requirements which an organization needs to fulfill if it is to achieve customer satisfaction through consistent products and services which meet customer expectations. It includes a requirement for the continual (i.e. planned) improvement of the Quality Management System, for which ISO 9004:2000 provides guidance.

ARI Performance Certified Mark ARI Performance Certified™ is the trusted mark of performance assurance for heating, ventilation, air conditioning and commercial refrigeration equipment. Products earning the mark undergo rigorous, independent annual evaluation to ensure that they perform according to the manufacturers’ published claims. Certifying HVACR equipment and component performance allows consumers to compare products based on independently verified performance ratings.
