ASTM WK80281
Revision of D7522/D7522M-21 Standard Test Method for Pull-Off Strength for FRP Laminate Systems Bonded to Concrete or Masonry Substrates
Rationale
This revision to D7522 adjusts the rate at which the load is applied to the specimen. The language has been harmonized with that found in related standard D7234 – Pull-Off Adhesion Strength of Coatings on Concrete. Pull-off tests are completed with a self-contained apparatus, and we have heard from users of D7522 and the manufacturers of the apparatus that is difficult to apply a continuous smooth loading at the low rates specified in the current standard.
