Standard Title: Evaluation of Adhesion Properties of Sealants - Strip Peel Method
Standard Number: GB/T XXXXX-XXXX (ISO 23658:2020, MOD)
Scope: This document describes the test method for evaluating adhesion properties of sealants with a minimum elongation at break greater than 25% to various substrates including but not limited to glass, aluminum, aluminum-plastic panels, and stone. It is applicable for the evaluation of sealant adhesion using the bead peel method.This document outlines methods for evaluating adhesive properties of sealants in relation to a variety of base materials, focusing on a test known as the strip peel method. The standard includes guidelines for sample preparation, aging procedures, and specific steps for conducting the peel tests. It applies specifically to situations where the sealant material's elongation at break exceeds 25%. Detailed sections cover pre-treatment processes for both sealants and substrates, alongside instructions on how to prepare test specimens using either manual or mold-based techniques.
Key components of this standard include considerations for environmental conditions during specimen preparation and aging phases, as well as detailed procedures for conducting the peel tests themselves. The document also provides guidance on interpreting results based on various failure modes observed in peel tests.
