Water quality. Determination of the toxicity of water samples on the embryo-larval development of Japanese oyster (<i>Crassostrea</i> <i>gigas</i>) and mussel (<i>Mytilus</i> <i>edulis</i> or <i>Mytilus</i> <i>galloprovincialis</i>)1 Scope This International Standard specifies a method for determining the effects of chemical and aqueous samples on the embryo larval development of marine bivalves. It allows the determination of the concentration levels that result in an abnormality in embryo larval development. This test is suitable for salinity ranges between 20 and 40 for mussels and between 25 and 35 for oysters. This method applies to chemical substances and preparations,

on the adhesion of the coating to either the preceding coat or the substrate

Why should you use BS AU 233 - Starter motor electrical connections for passenger cars

BS EN ISO 17637:2016 supersedes BS EN ISO 17637:2011 which is withdrawn

Users of BS EN 12763 can get guidance on the quality control measures and use the references for testing and inspection procedure for pipes and fittings

ISO 88713 on the determination of released-particle count in elastomeric parts is relevant to:

a lower compression strain is used: for a nominal hardness from 80 IRHD to 89 IRHD and for a nominal hardness from 90 IRHD to 95 IRHD

Excavators and other construction machines as defined in ISO 6165 are excluded
