levels of local turbulence

as (although some remain dual-numbered) many are now only known by their BS EN ISO reference

parallelism and squareness of working faces (solid iron block squares)

BS EN 1742 specifies a method of determining the shear strength under short-term loading between the different layers of prefabricated multilayer components made of autoclaved aerated concrete (AAC) according to prEN 12602 or lightweight aggregate concrete with open structure (LAC) according to prEN 1520
