Water quality. Determination of acute toxicity of water samples and chemicals to a fish gill cell line (RTgill-W1) Ingestion-build-183098

Water quality. Determination of acute toxicity of water samples and chemicals to a fish gill cell line (RTgill-W1) Ingestion-build-183098What is this standard about? This document specifies a method for the determination of fish acute toxicity using the permanent cell line from rainbow trout (Oncorhynchus mykiss) gill, RTgill W1. Cells in confluent monolayers in 24 well tissue culture plates are exposed to water samples, such as surface waters or different kinds of effluents, or to chemicals for 24 h and, thereafter, cell viability is assessed based on fluorescent cell viability

BS EN IEC 60947‑7‑4 provides specifications of connectors which is a bonus benefit to its users

It serves the objectives of an exposure assessment that can vary widely and include exposure exploration and determination

and to be immune to faults external to the transformer simultaneously
