Plastics — Marine biodegradation testing — Preparation of optimized intertidal seawater and sediment
This document specifies procedures for preparing seawater and sediments used in test methods to assess the biodegradation of plastic materials in the marine environment. The screened sediment and sediment-rinsed seawater are prepared to sustain aerobic testing at laboratory scale. The described method is designed to separate sediment-rinsed seawater and sand-gravel sediments from intertidal…
Medical laboratories — Concepts and specifications for the design, development, implementation and u...
The proposed standard document specifies requirements for ensuring quality, safety and performance of laboratory-developed tests (LDT). It outlines the general principles and assessment criteria by which LDT shall be designed, developed, manufactured, validated and monitored for internal use by medical laboratories.
While the proposed standard follows a current best practice and state-of-the art…
Textile floor coverings — Water impermeability test
ISO 20251:2016 specifies a laboratory test method for determining the water impermeability of textile floor coverings.
This method cannot be used to characterize a wall-to-wall installation of textile floor covering tiles.
