UL-Marking Services
The “UL” Mark is the single most accepted Certification Mark in the United States and is a “VOLUNTARY MARK”, not a “MANDATORY MARK”. It is also a “RESPECTABLE MARK”.
Difference between Listing, Recognition and Classification?
LISTING SERVICE -
A service whereby UL determines that a manufacturer has demonstrated the ability to produce a product that complies with UL requirements with respect to reasonably foreseeable risks associated with the product. As part of the service, UL authorizes the manufacturer to use the UL Listing Mark on products that comply with UL requirements and establishes Follow-Up Service conducted by UL as a check of the means the manufacturer exercises to determine compliance with UL requirements.
RECOGNITION SERVICE -
A service whereby UL determines that a manufacturer has demonstrated the ability to produce a component for use in an end product that complies with UL requirements. It takes into account the performance and constructional characteristics of such end product insofar as this can be determined and the areas that require additional consideration for application of the component to the product. UL authorizes the manufacturer to use the UL Recognized Marking.
CLASSIFICATION SERVICE -
A service whereby UL determines that a manufacturer has demonstrated the ability to produce a product that complies with UL requirements for the purpose of classification or evaluation with respect to one or more of the following:
(1) Specific risks only, e.g., casualty, fire or shock,
(2) Performance under specified conditions,
(3) Regulatory codes,
(4) other standards, including international standards, or
(5) such other conditions as UL may consider desirable. UL authorizes the manufacturer to use the Classification Mark on products that comply with UL requirements and establishes follow-up service as a check of the means the manufacturer exercises to maintain compliance with UL requirements.
CE-Marking involves:
The UL Mark is the single most accepted Certification Mark in the United States, appearing on 22 billion products annually.
A UL evaluation of a complete product to the applicable UL Standard is needed to determine how these components function as a system in your end product. The use of Recognized Components reduces the complexity of the evaluation and can save you time and money.
What do the numbers on the UL label mean?
The numbers on the UL Label are reference numbers assigned by UL and allow UL to control who the specific labels have been assigned to and for what type of products. This information is considered proprietary between UL and our customer to whom the UL label numbers were assigned.
