The provisions of this document apply to Single-Stage and economised refrigerant compressors of the positive displacement type. Selected test methods are described for the determination of the refrigerating capacity, the power, the isentropic efficiency and the coefficient of performance. These test methods provide results of sufficient accuracy to permit consideration of the suitability of a…
Plain bearings — Hydrodynamic plain journal bearings under steady-state conditions — Part 2: Functio...
This document specifies the characteristic values for selected two-, three- and four-lobe bearings.
The functions plotted and listed in table form below are required for the operationally safe design of hydrodynamic multi-lobed journal bearings according to ISO/TS 31657-1. They are based on the presumptions and boundary conditions indicated there and only apply to stationary operating states. The…
Information technology — Office equipment — Method for the determination of toner cartridge yield fo...
ISO/IEC 19752:2017 is limited to the evaluation of toner cartridge page yield for toner containing cartridges (i.e. all-in-one toner cartridges and toner cartridges without a photoconductor) for monochrome electrophotographic print systems. This document could also be applied to the printer component of any multifunctional device that has a digital input-printing path (i.e. multi-function devices…
This document defines the terms and definitions in the field of biodiversity. It includes terms from the observation of biodiversity loss (climate change, pollution, invasive species, erosion, soil degradation, deforestation, etc.) to the means of action to protect it (measurement, monitoring and assessment, restoration, conservation and protection, and sustainable use). The three dimensions are…
Cellular plastics — Polyethylene — Methods of test
ISO 7214:2012 specifies methods for testing flexible and semi-rigid cellular plastics made from polyethylene. Cellular plastics containing copolymers of ethylene or blends of polymers with polyethylene may also be tested by the procedures of this International Standard provided these materials have characteristics similar to polyethylene as described in ISO 1872-1, or copolymers of ethylene as…
Guidelines for addressing climate change in standards
This document provides guidance to standards developers on how to take account of climate change in the planning, drafting, revision and updating of ISO standards and other deliverables.
It outlines a framework and general principles that standards developers can use to develop their own approach to addressing climate change on a subject-specific basis.
It aims to enable standards developers to…
Railway applications — Heating, ventilation and air conditioning systems for rolling stock — Part 4:...
This document covers the following as a guideline:
- the basic design parameters to be provided to the HVAC unit manufacturer by the rolling stock manufacturer and the railway operator;
- the basic test/inspection items, requirements and methods used by the HVAC unit manufacturer.
This document specifies the contact tracing of the confirmed cases of infectious diseases for a public health emergency (PHE) response. The scope of the document includes:
overview and general procedures of contact tracing
requirements and privacy protection guidance in contact tracing The procedures given in this document may be applicable to the contact tracing except that the procedures…
Passenger car, commercial vehicle, truck and bus tyres — Methods for measuring snow grip performance...
ISO 18106:2016 specifies the method for measuring relative snow grip performance index of a candidate tyre compared to a reference, under loaded conditions for new tyres intended to be used on passenger car, commercial vehicle, truck and bus vehicles on a snow packed surface.
The methods developed here are meant to reduce the variability of the performance measurement. The use of the proper…
ISO 15957:2015 defines the properties of load test dusts used for heating, ventilation, and air conditioning (HVAC) air filters as well as air cleaning equipment in laboratories. Test dusts used for evaluation of efficiency performance are not included.
