Our test methods enable us to investigate your elastomeric gaskets and seals to the ANSI/UL 157, the Standard for Gaskets and Seals. In addition to evaluating your products for certain common physical properties, we’ll also evaluate them for specific end-use application requirements — providing you with an in-depth, fully rounded report.
To learn more about our gaskets and seals testing services, we’ve provided brief descriptions of each category and corresponding Category Code Number (CCN).
Gaskets and Seals (JMLU2)
This is our main gasket and seal category that covers elastomeric and composite gasket materials in various forms including O-rings, seals, shaft seals, flexible cellular gaskets, facings, sheet materials, special forms and poured-in-place gaskets. All materials are investigated with respect to properties including tensile strength, elongation, compression set, tensile set, hardness and low temperature. We’ll also test the retention of these properties after accelerated aging and exposure to various environments.
This category is designed to provide a profile of the material properties. These properties can help your product designers and engineers find materials that meet your requirements and comply with safety standards associated with your products. Materials may also be evaluated to specific end-product standard requirements as requested.
Gasket Materials (JMST2)
This category covers elastomeric materials supplied in sheet form or as formed or cut gaskets. These gaskets are evaluated for use in specific end-product applications.
Seal Rings (JOHX2)
This category covers O-rings, shaft seals, and other types of seals and special forms. These seals are evaluated for use in specific end-product applications.
Composite Gasket Materials (JMST)
This category covers composite gasket materials made from natural materials — cork, plant fibers or other fibrous materials — and a binder. Gaskets may be supplied in sheet form or as formed or cut gaskets. These gaskets are intended primarily for sealing finished, bolted joints on assemblies handling specific flammable and combustible liquids and/or gases.
