BS 6472-1 offers guidance on how people inside buildings respond to building vibration: the judgement criteria are more stringent at higher frequencies than in the superseded standard due to changes in the vertical frequency weighting

Degree of compactability BS EN 12350 4 specifies a method for determining the consistence of fresh concrete by determining the degree of compactability. It is not applicable to concrete of which the maximum size of aggregate exceeds 63 mm. If the degree of compactability is less than 1,04 or more than 1,46, the concrete has a consistence for which the degree of compactability test is not suitable. Contents
