UL PERFORMANCE MATERIALS
UL YELLOW CARD FOR PLASTICS ADD MORE PROPERTIES, WIN NEW CUSTOMERS
WHAT IS A UL YELLOW CARD?
The Yellow Card is a globally respected digital product information card that lists multiple safety and performance-related properties for a polymeric material tested by UL to appropriate standards.
It is the ideal recognition for manufacturers of materials or components to promote products and their properties to global markets and existing or potential customers. The card provides substantial information on safety certification and performance testing in a very compact, simple and easy-to-read format.
It provides verification that a material is appropriate for specific applications and helps ensure that the manufacturer is using a tested and certified material, as well as being monitored at regular intervals by an independent test laboratory.
UL TESTING CAN INCLUDE:
• I gnition and burning characteristics from thermal and electrical sources • E lectrical, physical and mechanical characteristics
• T he effect of exposure to elevated temperatures, cold, water, ultraviolet rays, chemical fluids, etc.
A Yellow Card is automatically issued when polymeric materials receive a UL Recognized Component Mark. Certified materials are added to the UL iQ TM and UL’s Prospector® databases – bringing immediate visibility to your Yellow Cards as thousands of designers, engineers, and suppliers search and utilize our databases monthly to verify important safety and performance critical features.
As a As a plastics manufacturer, you undertake rigorous measures to ensure your prod
products meet the safety standards as well as quality and performance requ
requirements of OEMs. That’s where the UL Yellow Card comes into play – as a
as a safety and quality guarantee, and a low-maintenance marketing tool.PERFORMANCE & CERTIFICATION. SIMPLIFIED.
HISTORY OF THE YELLOW CARD – THE START OF A NEW AGE OF SAFETY When the “golden age” of plastics started in the early 1940s,
UL began to investigate the combustibility of new synthetic polymers. The first Yellow Cards recorded all components certified under UL’s Component Recognition Program, including plastics, switches and all other devices intended for use in finished products. Companies used the 3x5 inch cards on yellow stock to promote the safety of their products to customers. By the late 1960s, in addition to the manufacturer’s name and the material grade designation, the Yellow Card included the UL 94 Flame Rating. In 1972, UL published the first “Yellow Book, a directory for all client test data and the predecessor of the current UL iQ TM database.

UL Yellow Cards are not limited to certification – they can be a highly effective marketing tool. The best method to add value to a Yellow Card is to increase its coverage beyond safety
certification parameters. Material manufacturers can boost product discoverability by including the performance properties their customers are looking for – all backed up with reliable t h ird-party verification by UL.
UL Yellow Cards are listed in various UL databases, which are used by end product manufacturers to find providers of verified materials and components. If they search for specific material properties and don’t find your products, they’ll choose another provider.
YELLOW CARDS HELP
MANUFACTURERS FIND YOU
UL IQ TM DATABASES
The UL iQ TM family of free databases is a suite of relational databases that allow users to search for UL Certified Components and review relevant safety certification and material performance data. A website link can be added to an existing yellow card, allowing users to quickly access a provider-specific website. The URL can lead to your company website, product brochure, contact information page, or any other website page. Each yellow card can have one unique product link. iq.ul
PROSPECTOR® DATABASE
UL’s Prospector® is the premier database for manufacturers to quickly find the precise materials they need. Bringing together thousands of
suppliers, Prospector offers an online service to sort and search materials by properties, applications, safety data, performance characteristics and more. Prospector offers a Yellow Card plug-in – enabling you to showcase your compliance and performance test data in the trusted UL Yellow Card format on your own company website.
ULProspector
ADD PERFORMANCE CREDENTIALS, BOOST VISIBILITY.VISIBILITY.
For example, with a Yellow Card, material manufacturers can provide reliable evidence that their products meet important industry requirements, such as the ROHS Directive or a non-halogen and non-chlorine & non-bromine certification.
THE WHITE CARD
PROMOTE YOUR INTER-NATIONAL QUALIFICATIONS
The White Card, an extension at the bottom of a Yellow Card, allows you to promote your product‘s performance credentials to the global markets. It relates to international standards, while the information on the Yellow Card is typically relevant to North America.

HOW TO READ A YELLOW CARD
A Yellow Card contains multiple specialized terms and abbreviations. See below for an explanation of the terms and abbreviations most commonly found on UL Yellow Cards.
Note: For some tests a Performance Level Category (PLC) may be assigned. This is typically a numeric rating from 0 – 5, where each number represents a range of property values, and 0 represents the best rating available.
94
Tests for Flammability of Plastic Materials for Parts in Devices and Appliances, now harmonized with IEC 60695-11-10, 60695-11-20, ISO 9772 and ISO 9773. There are twelve UL 94 specified flame classifications assigned to materials based on the results of these small-scale flame tests.
The test method for the determination of resistance to ignition of plastic materials from an electrically
heated wire is described in the Standard ASTM D 3874.
The HAI test determines a material’s ability to withstand electrical arcing either directly on or just above the surface of the plastic material. This can occur in the presence of open switch contacts or in the event of the failure of an electrical connection.
The maximum service temperature for a material where a class of critical property will not be unacceptably compromised through chemical thermal degradation over the reasonable product lifeti
me. Electrical RTI is associated with critical electrical insulating properties. Mechanical impact RTI is associated with critical impact resistance, resilience and flexibility properties. Mechanical strength RTI or mechanical without impact is associated with critical mechanical strength where impact resistance, resilience, and flexibility are not essential.
ASTM D 3638 (IEC 60112) Method: This test is used as a measure of the susceptibility of the material to tracking.
The test method for the determination of the dielectric breakdown and strength of insulating materials, described in the Standard ASTM D 149 (IEC 60243).
Test method to determine the susceptibility of the test material to track or form a visible carbonized conducting path over the surface when subjected to high-voltage, low-current arcing.
For measuring changes in linear dimensions of plastics, described in the Standard ASTM D 1042 (ISO 2796).
Described in the Standard ASTM D 2303, used as a measure of the susceptibility of a material to track.
Testing according to ASTM D 257 (IEC 60167), procedures for the determination of d-c volume resistance, volume resistivity, surface resistance, and surface resistivity of electrical insulating materials.
Testing to ASTM D495, based on the number of seconds that a material resists the formation of a surface-conducting path when subjected to an intermittently occurring arc of high-voltage, low-current characteristics.
