The H2HUBB RPC Agreement outlines how H2HUBB approval and recommendation work between H2HUBB and a product company. It explains the process for product submission, independent testing and evaluation by H2HUBB, accreditation fees, accuracy of product claims, and the requirement for ongoing compliance with H2HUBB performance and safety standards. The agreement also describes how approved products may be listed and promoted within the H2HUBB marketplace. Either party may discontinue the agreement with a two-week notice by email. If the agreement is terminated, H2HUBB will remove its recommendation and marketplace listing, and the company must remove all H2HUBB assets and references from its website and marketing materials.

H2HUBB uses independent, instrument-based testing to measure performance and verify claims. Methods may include:

• Custom H2HUBB Unisense H2 Microsensor testing (dissolved hydrogen verification where applicable)
• Alicat Mass Flow Meter verification (hydrogen gas flow rate testing where applicable)
• Electrolysis montioring technology (Voltage meters, amp shuts, etc)
• Supporting measurement tools depending on device type and evaluation scope

Typical evaluation timelines range from 4–12 weeks, depending on product type, queue volume, and whether additional testing or follow-up verification is required.

Marketplace listing occurs after evaluation and testing, and is published in coordination with the RPC. Once approved, products are added to the appropriate marketplace category (and Premier Products when applicable).
