Sludge and solid environmental matrices — Determination of dry residue or water content and calculat...
The method specified can be applied to all types of soil samples. Different procedures are specified for air-dried soil samples, e.g. samples pretreated according to ISO 11464, and for field-moist soil samples. Its principle is drying soil samples to constant mass at 105 °C and using the difference in mass of an amount of soil before and after the drying procedure to calculate the dry matter and…
Information technology — Office equipment — Method for measuring first print out time for digital pr...
ISO/IEC 17629:2014 specifies a method for measuring first print out time of digital printing devices. It is applicable to digital printing devices and multifunctional devices. It is intended to be used for black and white (B&W) as well as colour digital printing devices and multifunctional devices of any underlying marking technology. It includes instructions for test charts, test setup…
Glass in building — Determination of the emissivity
This document specifies a procedure for determining the emissivity at room temperature of the surfaces of glass and coated glass.
The emissivity is necessary for taking into account heat transfer by radiation from surfaces at the standard temperature of 283 K in the determination of the U value and of the total solar transmittance of glazing.
The procedure, being based on spectrophotometric…
Tritium and carbon-14 activity in gaseous effluents and gas discharges of nuclear installations — Pa...
ISO 20041-2 describes analysis methods for the determination of tritium and carbon-14 activities by liquid scintillation counting and calculation methods to determine the tritium activities discharged as tritiated water vapour (HTO) and tritium in other chemical compounds (non-HTO) as wells as carbon-14 activities discharged as carbon dioxide (14CO2) and carbon-14 in other chemical compounds (non…
Air quality — Bulk materials — Part 2: Quantitative determination of asbestos by gravimetric and mic...
ISO 22262-2:2014 specifies procedures for quantification of asbestos mass fractions below approximately 5 %, and quantitative determination of asbestos in vermiculite, other industrial minerals and commercial products that incorporate these minerals.
ISO 22262-2:2014 is applicable to the quantitative analysis of:
a) any material for which the estimate of asbestos mass fraction obtained using ISO…
