Issues regarding the retesting of materials entering the site for installation projects
Thread Content
Could everyone help by asking whether the paint used for corrosion prevention, the rock wool for insulation, and the grouting material used for secondary grouting need to be retested upon arrival? If so, which standards specify this requirement?
Here, we generally require the construction contractor to provide the qualification documents of the insulation manufacturer, as well as the certificates of conformity and quality certificates for the insulation materials. It’s not easy to look into this by oneself, right?
