US qualification standard
ASTM C1581/C1581M - Standard test method for determining age at cracking and induced tensile stress characteristics of mortar and concrete under restrained shrinkage
In short
ASTM C1581/C1581M - Standard test method for determining age at cracking and induced tensile stress characteristics of mortar and concrete under restrained shrinkage. Amstelfy's laboratory in Amstelveen performs this ASTM method for mortar and concrete: restrained shrinkage (ring test). 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.
What we assess
- restrained shrinkage (ring test)
Products covered
- mortar and concrete

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.
