Rubber and rubber products — Determination of biobased content — Part 2: Biobased carbon content
ISO 19984-2:2017 specifies measuring methods for the determination of biobased carbon contents in rubber and rubber products, including polyurethanes. The methods focus on carbon atoms in rubber or rubber products, and determine whether the carbon-containing component is biobased or not judging from the concentration of 14C, radiocarbon isotope.
ISO 19984-2:2017 applies to rubber and rubber…
Information technology — Portable Operating System Interface (POSIX®) base specifications — Issue 8
ISO/IEC/IEEE 9945:2009 defines a standard operating system interface and environment, including a command interpreter (or "shell"), and common utility programs to support applications portability at the source code level. ISO/IEC/IEEE 9945:2009 is intended to be used by both application developers and system implementers and comprises four major components (each in an associated volume…
General requirements for establishing muscular strength databases
The proposed ISO standard (on the line of ISO 15535) is being prepared to help different researchers/ national standard bodies in generating internationally compatible strength databases. The standard will include data collection design and requirements, sampling techniques, sample size, sample composition, and basic demographic description of participants. It will also specify database format…
Soil and waste — Determination of chromium(VI) in solid material by alkaline digestion and ion chrom...
This document specifies the determination of Cr(VI) in solid waste material and soil by alkaline digestion and ion chromatography with spectrophotometric detection. This method can be used to determine Cr(VI)-mass fractions in solids higher than 0,1 mg/kg.
NOTE In case of reducing or oxidising waste matrix no valid Cr(VI) content can be reported.
Steel and cast iron — Determination of nickel content — Flame atomic absorption spectrometric method
The method is applicable to nickel contents between 0.002 % (m/m) and 0.5 % (m/m). Specifies principle, reagents, apparatus, sampling, procedure, expression of results and test report. Annex A gives additional information on the international co-operative tests, and Annex B represents the precision data graphically.

- specifies the processes from ISO/IEC/IEEE 15288 that implement systems engineering management for the life cycles of technical solutions,
- describes a required information item, termed the Systems Engineering Management Plan (SEMP) for the technical management and execution of the systems engineering of technical solutions,
- provides requirements and…
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…
