BS EN 16150 gives guidance on procedures for the pro-rata Multi-Habitat-Sampling (MHS) of benthic macro-invertebrates in wadeable rivers and streams

Tissue paper and tissue products - Determination of optical properties. Measurement of brightness and colour with D65/10° (outdoor daylight) Ingestion-build-258901 reliability qualification requirements1 Scope This part of ISO 12625 specifies testing procedures for the instrumental determination of brightness and colour of tissue paper and tissue products viewed under outdoor daylight conditions. It also gives specific instructions for the preparation of test pieces (single ply, multi ply products) and for the optical measurements of products, where special precautions may be necessary. NOTE The properties called C 2 brightness and colour are
