Liquid-cooling technologies are critical for supporting the burgeoning data center market. By 2030, the direct-to-chip liquid cooling market is expected to exceed $5.6 billion (USD), with a compound annual growth rate of 19.7%.1
Gasket materials are an essential part of liquid-cooling systems, providing protection from contaminants at enclosure joints and connection points. These components, including O-rings and seals, need to support reliability and performance of the cooling system.
To help specifiers identify gaskets and seals that support the performance of liquid cooling systems, UL Solutions offers component certification. Elastomeric and composite gaskets and seals are classified under the JMLU2 category and are evaluated according to UL 62368-1, the Standard for Audio/Video, Information and Communication Technology Equipment - Part 1: Safety Requirements.
Seals and gaskets with UL Certification to the JMLU2 Recognized Components have demonstrated compliance with relevant performance requirements.
UL Certification helps manufacturers prequalify components earlier in the product development cycle, streamlines compliance evaluations and supports faster time to market
Global recognition and market access – Certification supports regulatory acceptance in international audio-visual (A/V), information and communications technology (ICT) and data center markets.
Greater visibility to specifiers – Certified components are easily searchable in Product iQ®, our online location for certification information. This access offers buyers details about material selection and helps accelerate system approvals.
Comprehensive evaluation of long-term performance – We offer liquid compatibility testing that showcases a component’s durability when exposed to system cooling fluids.
Gasket performance
Sealing materials are tested to assess mechanical performance with respect to properties including:
Components are also tested for how they retain these properties after accelerated aging and exposure to various environments.
Additionally, gaskets intended for use in an outdoor enclosure subjected to oil or coolant must be evaluated for oil resistance.
UL 62368-1 requires testing for both self-contained and modular liquid-cooling systems to evaluate tensile strength properties.
Components are also tested as to their ability to retain tensile strength properties following a 40-day conditioning test in which components are submerged in the intended cooling liquid.
The certification process also allows for preselection testing to establish a comprehensive list of qualified liquids in which components may be submerged.
As a trusted safety science leader, UL Solutions provides third-party testing and certification of components to showcase performance and compliance in gaskets and seals.
Our testing program aims to certify your products as UL Recognized Components. Once certified, they can be published in our Product iQ™ Database – showcasing their compliance to OEMs, purchasers and regulatory authorities around the world.
UL Solutions’ extensive certification program for elastomeric materials offers Component Recognition for UL 50E, the Standard for Electrical Equipment Enclosures, facilitating the acceptance of these components in end products.
As a recognized leader in testing and certification, we’ll help ensure that your products meet industry standards — providing third-party Verification of their quality, common physical properties and end-use applications.
