ICC-ES AC320 - Acceptance criteria for fiber-reinforced polymer composite or unreinforced polymer connectors anchored in concrete

Testing · NAC-037-TL

In short

ICC-ES AC320 - Acceptance criteria for fiber-reinforced polymer composite or unreinforced polymer connectors anchored in concrete. Amstelfy's laboratory in Amstelveen performs this US qualification protocol for FRP and polymer connectors for sandwich panels: tension and shear capacity, durability and creep. Testing is on the ISO/IEC 17025 accreditation scope NAC-037-TL, which lets European manufacturers prepare US evaluation-report programmes without shipping samples overseas.

Route to market

US and international evaluation-report programmes (ICC-ES, IAPMO UES, ACI 318 qualification) accept data from ISO/IEC 17025-accredited laboratories. Amstelfy runs these programmes in the Netherlands so European manufacturers avoid shipping samples overseas; the evaluation report itself is issued by the evaluation service.
