This document specifies the procedures for producing substrates of mortar, glass and anodized aluminium used for testing sealants.
The purpose of these requirements is to ensure the reproducibility of the standardized tests conducted on sealants through the precise definition of both the composition and the method of preparation of the test substrates.
The substrates defined in this document are ## Source - https://isopublicstorageprod.blob.core.windows.net/opendata/_latest/iso_deliverables_metadata/csv/iso_deliverables_metadata.csv Last verified: 2026-08-05.
