The effect of the thermal barrier material on the dimensional tolerances is covered by BS EN 12020-2 although the actual thermal barrier material itself is not (see BS EN 14024)

BS EN 681-1 should be used where appropriate with product standards which specify performance requirements for joints

Testing fresh concrete - Sampling Ingestion-build-221493 Organization that want to implementBS EN 12350 1: 2009 Testing fresh concrete. Sampling BS EN 12350 1 specifies two procedures for sampling fresh concrete, by composite sampling and by spot sampling. The requirement for remixing the sample before tests on the fresh concrete, or before making test specimens, is included in the relevant standards. When mixing and sampling of concrete is done in a laboratory, different procedures may be required. Contents of BS EN 12350 1: Foreword Scope
