Biotechnology — Cell counting — Part 1: General guidance on cell counting methods
ISO 20391-1:2018 defines terms related to cell counting for biotechnology. It describes counting of cells in suspension (generally cell concentration) and cells adhered to a substrate (generally area density of cells). It provides key considerations for general counting methods (including total and differential counting, and direct and indirect counting) as well as for method selection,…
Liquid hydrogen — Land vehicle fuel storage system
ISO 13985:2006 specifies the construction requirements for refillable fuel tanks for liquid hydrogen used in land vehicles as well as the testing methods required to ensure that a reasonable level of protection from loss of life and property resulting from fire and explosion is provided.
It is applicable to fuel tanks intended to be permanently attached to land vehicles.
Textile and laminate floor coverings — Assessment of static electrical propensity — Walking test
ISO 6356:2012 specifies a method of evaluating the electrostatic propensity of textile and laminate floor coverings under controlled conditions. Since the potential generated varies with humidity, shoe materials, walk surface and individuals' mannerisms, the values generated by this test will not necessarily duplicate actual field experience, but will provide a relative comparison of the…
