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,…
Sustainable mobility and transportation — Roadside feeding electric road system — Part 1: Service ro...

Horizontal methods for molecular biomarker analysis — Methods of analysis for the detection of genet...
This International Standard describes a procedure for the detection of a DNA sequence of a construct used to (genetically) enhance the growth of fish commonly found in aquaculture. The genetically modified AquAdvantage Atlantic salmon (Salmo salar) carries this construct and can be detected based on a real-time PCR targeting the border between the growth hormone coding sequence (CS-GHc2) of…
Corrugated fibreboard — Determination of flat crush resistance
This International Standard specifies a method for the determination of the flat crush resistance of corrugated fibreboard used in the manufacture of shipping containers.
This International Standard is applicable to single-faced and single-wall (double-faced) corrugated fibreboard.
This International Standard is not applicable to double-wall (double-double-faced) corrugated fibreboard and to…
ISO 1953:2015 specifies reference methods for the size analysis of coal by manual sieving (wet or dry), using test sieves of aperture sizes between 125 mm and 45 μm. A guide to sampling is given in Annex A.
This International Standard is applicable to all hard coals. It is not applicable to coke or other manufactured fuels.
In the case of pulverized coal which has been ground so that a high…
Water quality — Estimation of measurement uncertainty based on validation and quality control data
This International Standard specifies methods for the estimation of measurement uncertainty of chemical and
physicochemical methods in single laboratories based on validation data and analytical quality control results
obtained within the field of water analysis.
NOTE 1 The principles of the estimation of uncertainty specified in this International Standard are consistent with the
principles…
