Wall ties are covered by Council Directive 89/106/EEC, colloquially EU Construction Products Directive. Consequently wall ties are subject to a common European standard requesting CE-marking.
Wall ties are covered by product standard DS/EN 845-1 Specification for ancillary components for masonry - Part 1: Ties, tension straps, hangers and brackets. The standard can be downloaded from Danish Standard.
Certificate of Compliance and CE-marking are available for the individual wall tie products.
