Specification of technical grade sulphur hexafluoride (SF<sub>6</sub>) and complementary...
IEC 60376:2018 defines the quality for technical grade sulphur hexafluoride (SF6) and complementary gases such as nitrogen (N2) and carbon tetra-fluoride (CF4), for use in electrical equipment. Detection techniques, covering both laboratory and in-situ portable instrumentation, applicable to the analysis of SF6, N2 and CF4 gases prior to the introduction of these gases into the electrical…
Testing methods for pervious concrete — Part 2: Density and void content
This document specifies a procedure for testing the density and void content of freshly mixed and hardened pervious concrete specimens for pavement in the laboratory or cored from field placements.
This document also specifies formulae for calculating the density and void content of pervious concrete.
Protective clothing for firefighters — Physiological impact — Part 2: Determination of physiological...
This document specifies a method for evaluating the thermo-physiological impact of protective fabric ensembles and potentially protective clothing ensembles in a simulated activity under defined relevant conditions for firefighters.
This document is intended to be used to assess the thermo-physiological impact of protective fabric ensembles and potentially protective clothing ensembles but not…
Water quality — Sampling — Part 3: Preservation and handling of water samples
This document specifies general requirements for sampling, preservation, handling, transport and storage of all water samples including those for biological analyses.
It is not applicable to water samples intended for microbiological analyses as specified in ISO 19458, ecotoxicological assays, biological assays and passive sampling as specified in the scope of ISO 5667‑23.
This document is…
Vacuum technology — Vacuum gauges — Characterization of quadrupole mass spectrometers for partial pr...
This document describes procedures to characterize quadrupole mass spectrometers (QMSs) with an ion source of electron impact ionization and which are designed for the measurement of atomic mass-to-charge ratios m/z < 300.
This document is not applicable to QMSs with other ion sources, such as chemical ionization, photo-ionization or field ionization sources and for the measurements of higher…
Reciprocating internal combustion engines — Exhaust emission measurement — Part 6: Report of measuri...
ISO 8178-6:2018 specifies a data format for reporting the measurement results of exhaust emissions from RIC engines for mobile, transportable and stationary use, excluding engines for motor vehicles primarily designed for road use. It includes basic information of the engine being tested. Equivalent data formats including those that are electronically generated can be used as long as the required…
ISO 28319:2018 specifies requirements and test methods for laser welding and the filler materials thereto used in the dental laboratory for welding of metallic restorations and appliances.
For filler materials used in laser welding, this document also specifies the information given in the instructions for use, marking and labelling.
ISO 16332:2018 specifies a fuel/water separator comparison test under defined and simplified laboratory conditions.
This test is intended for pressure side fuel/water separators as well as for suction side fuel/water separators. Pressure side fuel/water separators are tested with fine droplets and suction side filters are tested with coarse droplets using the same test rig layout.
The rated flow…
Requirements for the design, development, and validation of laboratory-developed tests used for the ...
1 Scope
1.1 General
This Standard specifies the minimum requirements and best practices for the development, validation, and use of laboratory-developed tests in clinical and research laboratories for the screening, diagnosis, and management of clinical conditions.
It does not provide specific details on how to achieve these requirements since they are provided in many other sources which are…
Surface chemical analysis — Total reflection X-ray fluorescence analysis of water
ISO 20289:2018 provides a chemical method for technicians working with Total Reflection X-ray Fluorescence (TXRF) instrumentation to perform measurements of water samples, according to good practices, with a defined degree of accuracy and precision. Target users are identified among laboratories performing routine analysis of large numbers of samples, which also comply with ISO/IEC 17025.
ISO…
