◉ Certification Introduction
UL is short for Underwriters Laboratories Inc. The UL Safety Laboratory is the most authoritative in the United States and the largest private institution engaged in safety testing and identification in the world. It is an independent, for-profit professional organization that conducts experiments for public safety. Since its founding in 1894, UL has published nearly 1,800 safety, quality and sustainability standards, more than 70% of which have become American National Standards, and UL is also the developer of Canadian National Standards.
UL certification is a non-mandatory certification in the United States, mainly testing and certification of product safety performance, and its certification scope does not include the EMC (electromagnetic compatibility) characteristics of products.
◉ Certification Mark
1. UL Listed Mark
Mainly used in general end products that consumers can buy directly from the market, such as home appliances, computers, heaters, fuses, power strips, smoke detectors, fire extinguishers and other products. Any product with the UL listed mark indicates that a representative sample of the product complies with the relevant UL safety standards. This series of flags includes three flags for the United States, Canada and the United States and Canada.
2, UL classification mark
When a product has a specific hazard, specific attribute, limited or special use condition, or even a product regulated by law, the UL classification mark needs to be used. Classification markings address one or more of the following requirements: specific risks, such as casualties, fire, etc.; performance under specific conditions; specific code requirements; specific standards, etc. Common products such as fire doors, fire hydrants, medical equipment, ice machines, etc. This series of flags includes three flags for the United States, Canada and the United States and Canada.
3. UL recognized parts mark
It is mainly used in component products used in finished assembly plants or other component factories, such as plastics, capacitors, printed circuit boards, complex high-tech components and industrial control components. UL Component Certification helps component suppliers create added value by providing an objective method to demonstrate that components meet applicable regulatory requirements, and can help reduce time-to-market for products using UL-approved components.
4. UL upgrade certification mark
The upgraded version of the UL certification mark integrates multiple UL certifications in different regions into a unified mark, realizing that one certification mark "carries" multiple certification information in different regions. Each logo has a unique identification code that provides more detailed certification information for a specific product. UL's upgraded certification mark can integrate more new certification categories, provide traceability and smart mark functions.
5. UL verification mark
The UL Verification Mark provides objective, science-based third-party testing and verification for manufacturers' marketing claims for their products, such as product performance, quality, and function claims.
6. UL GREENGUARD certification mark
UL GREENGUARD is a certification for low release of chemical substances in indoor products, ensuring that the release of chemical substances from products meets the minimum limit requirements. UL GREENGUARD is available for more than 480 product types in 26 industries, including building materials, upholstery, furniture, cleaning supplies and electronic equipment.
7. UL ECOLOGO certification mark
ECOLOGO certification is a multi-attribute certification standard based on UL's product life cycle. It conducts third-party audit and certification of products, and finally certifies the green performance of products. The certification evaluates more than 350 codes and standards, including a number of programs for green building, environmental codes, responsible sourcing, green certification, and more.
8. UL Environmental Declaration Verification Mark
UL environmental declaration verification is to verify the environmental protection indicators of a certain aspect of the product. Qualified enterprises or manufacturers can use the UL environmental declaration verification mark in product packaging and marketing materials. Specifically, it includes: bio-based ratio, recyclable material content, rapid recycling material, zero waste to landfill, VOC content, etc.
9. UL Environmental Product Declaration Mark
UL Environmental Product Declarations are developed in accordance with the Product Category Rules (PCR) to provide manufacturers with a credible environmental transparency report containing all environmental information about a product throughout its life cycle (LCA), from material selection to post-use-life disposal and so on.
◉ Product Range
UL is mainly responsible for public safety inspections of electrical, electronic equipment, mechanical products, lamps, building materials, fire protection equipment and chemicals.
◉ UL certification For Electrical Products
The UL certification of electrical products is divided into three types: listing, approval and classification:
Listed is applicable to complete products and various components and devices that are replaced or installed on-site by qualified personnel, such as complete household appliances;
Recognized (Re cognized ) applies to the components and raw materials of the product. These components cannot directly constitute a complete product by themselves, or their use is limited, such as safety components used in household appliances - switches, fuses, capacitors, seals There are two types of approved tracking services: R-type and L -type; L-type is mainly used for products related to life safety, such as fire extinguishers, detectors, electrical equipment, wires, etc. For products belonging to category L. Manufacturers must order the mark directly from UL and affixed to the product. Class R products are mainly electrical equipment, such as TVs, fans, hair dryers, ovens, etc.
Classification is applicable to the specific hazards of products, or the evaluation of products that implement standards other than UL standards. The flame retardant registration of materials in household appliances belongs to the category of classification services.
◉ Authenticationinformation
1. Product Name: Provide the full name of the product.
2. Product model: List all product models, varieties or classification numbers that need to be tested in detail
3. Product nameplate: including product model, electrical parameters, manufacturer information, production date, UL logo
4. The intended use of the product: for example: home/commercial, indoor/outdoor, etc.
5. Parts list: detail the components and models (file numbers), rated values, and manufacturers that make up the product
6. Electrical properties: for electronic and electrical products. Provide electrical schematic diagram (circuit diagram), PCB LAYOUT
7. Structure diagram: For most products, the structure diagram or exploded diagram, ingredient list, etc. of the product should be provided.
8. Product instruction manual and installation manual, etc.
9. UL special application form corresponding to specific products
◉ Certificationprocess
1. Submit the test application form
2. Provide samples and materials
3. Sample detection
4. Issue a test report
5. Factory inspection
6. Obtain UL authorization and certificate
7. Four annual factory audits
◉ CUL Certification
The CUL mark is the UL mark used to distribute products in the Canadian market. Products with this mark have been verified to comply with Canadian safety standards, which are basically the same as the standards cited by UL in the United States. Of course, the standards of some products are also different. For example, there are two sets of standards for hand-held power tools: UL45 applies only in the United States. UL745-1 applies to the United States and Canada. The two standards are similar, both derived from the International Electrotechnical Association IEC60745--Safety standard for hand-held motor-driven tools. The CUL mark is widely used in household appliances, computer equipment, ventilation equipment, household anti-theft systems and other types of products.
Enterprises may encounter Canadian customers when exporting, requiring products to have CUL certification. After CUL certification, the product meets the safety requirements of all provinces in Canada. There is an advantage to applying for CUL at the same time as applying for UL, because many test items of UL and CUL are repeated, so when applying for CUL, you only need to do a few less items, and then add one more application process, so that you can use it at a lower cost. Obtain two-country certification at one time in a relatively short period of time
