Assessment Capable Entities (ACE) are organisations that are capable of determining the range of tests required to certify a product and assessing all the test results to ensure the product satisfies The GCF certification criteria.
Suitably qualified members can offer their services as Third Party Assessment Capable Entities (TPACE) to assist associate manufacturer members with the certification of their connected products.
Note that ACE status is separate from Recognised Test Organisation (RTO) status. A manufacturer may use any RTO. But the ACE would need to be satisfied that testing has been properly completed before they choose to accept the results from whichever RTO has been used.
