UL Recognized Gasket Materials – PDF Version

Since 1894, Underwriters Laboratories has provided safety testing and assessment of electrical products, equipment, and parts. As a fully independent organization, Underwriters Laboratories (UL) is trusted by the Occupational Safety and Health Administration (OSHA) for its ability to provide thorough and reliable 3rd party product safety testing for electrical and mechanical products, and their components around the world.

Engineers are encouraged to use UL rated components to improve safety and improve likelihood of UL approval of final product. This includes components like gaskets. UL gaskets, like those at Monmouth Rubber & Plastics, provide the safety and structural integrity that products need to go to market.

What Testing is Performed on UL Gaskets?

Underwriters Laboratories has a set of industry standards that it uses to test electronic components, including gaskets. UL Gaskets are tested using the Standard for Safety of Gaskets and Seals, also known as “UL 157.” This applies to most types of gaskets, including:

• Elastomer Gaskets
• Thermoplastic Gaskets
• Composite Gaskets
• Coated Fabrics

As well as many common forms, including:
• O-Rings
• Sheets
• Slabs
• Rolls
• Shaft Seals
• Diaphragms
• Special Forms

The UL 157 Standards for Safety of Gaskets and Seals includes many critical safety tests, including a tensile strength and elongation test, an accelerated air-oven aging test, a compression set test, a low temperature test, a hardness test, an immersion test, a detergent/cleaner test, a bursting strength test, and several others.

The following are all of our UL Gaskets with UL 157 Listings:

Other UL Listings for Gaskets and Materials

UL Gasket Testing may not be limited to UL 157. The following are several other possible listings for gaskets, rubber, and related components.

• UL 50 and 50E – Enclosures for Electrical Equipment

UL 50 is the standard applied to how effective a component is for protecting electrical enclosures from penetration by foreign objects. “Objects” includes dirt, water, dust, humans – anything that could affect the safety or efficacy of the electronic parts. U L 50E is a higher level standard than just UL50.

50E standard applies to enclosures for electrical equipment intended to be installed and used in non-hazardous locations in accordance with the Canadian Electrical Code, Part I, CSA C22.1, the provisions of the National Electrical Code, NFPA 70, and the provisions of Mexico’s Electrical Installations, NOM-001-SEDE,

UL 50 standards are a complementary standard for cellular gasket materials that are used in periodic recompression applications, rather than continuous compression applications. NOTE: Enclosure design may play a role in longevity of UL 50 gaskets. Although a UL Gasket may be UL 50 or UL 50E rated, it may not account for the effects of the final product design.

The following are all of our UL Gaskets with UL 50 Listings:

  • UL 94 – Standard for Tests of Flammability These requirements cover tests for flammability of polymeric materials used for parts in devices and appliances. They are intended to serve as a preliminary indication of their acceptability with respect to flammability for a particular application.
  • The methods described in this Standard involve standard size specimens and are intended to be used solely to measure and describe the flammability properties of materials, used in devices and appliances, in response to a small open flame or radiant heat source under controlled laboratory conditions

Like UL 50, not all UL Gaskets are tested for UL 94 standards. But Underwriters Laboratories regularly tests for flammability, to determine which gaskets are fire resistant. There are several burn tests that may be performed, including:

  • Horizontal Burning Test (UL 94HB)
  • 50W Vertical Burning Test (UL 94V-0)
  • 500W Vertical Burning Test (UL 94 5VA)
  • Radiant Panel Flame Spread Test
  • Thin Material Vertical Burning Test (UL 94VTM)
  • Horizontal Burning Foam Material (UL 94HBF)

Not all material manufacturers perform the UL 94 test. Some use historical testing to determine if a component is “capable” of passing the UL 94. Although often times the product is capable, it is not recognized to have passed the test. In addition, UL 94 testing is affected by product thickness. Engineers should take this into consideration with their designs.

Some of the products at Monmouth that qualify for a UL 94 rating include:

Additional UL Gasket Listings and Information

 

Certain UL gaskets may require additional testing depending on the type of design. Some of the listings that may be considered include:

  • UL 1570 (Fluorescent Lighting Fixtures)
  • UL 1571 (Incandescent Lighting Fixtures)
  • UL 1572 (HID Lighting Fixtures)
  • UL 8750 (LED Lighting Fixtures)
  • UL 1598C (LED Retrofit Fixtures)
  • UL 60947 (Industrial Control Equipment, Formerly UL 508)

The UL 508 rating, which applied to UL Gaskets in Industrial Control Equipment, is currently being phased out in favor of UL 60947. All UL 508 listed components should continue to qualify for the new UL 60947 standards.

UL 508 migration to UL60947-4-1A
The standard for Industrial Control Equipment UL 508 is being harmonized with relevant IEC standards for Low-Voltage Switchgear and Control Gear IEC 60947. Effective Jan. 27, 2017, all UL 508 certified products must meet the new UL 60947-4-1A standard. This does not invalidate any existing UL508 certifications. According to UL, “While the UL 508 and UL 60947 series standards do not look the same, when taking into account the national differences included in the harmonized standards, they are essentially technically identical.” As such, this harmonization does not represent a substantial change in design requirements for UL 508 products. It is also important to note that the UL 508A Standard for Safety Industrial Control panels is not directly affected by the UL 508 to UL60947-4-1A migration.
