Plastics — Determination of the aerobic biodegradation of plastic materials exposed to seawater usin...
This document describes a laboratory test method to determine the aerobic biodegradation of plastic materials exposed to seawater using accelerated conditions.
Furthermore, this document describes the general requirements of the apparatus and the procedures for using this test method. The biodegradation is determined by measuring the oxygen demand in a closed respirometer or by measuring the CO2…
Fans — Determination of fan sound power levels under standardized laboratory conditions — Part 3: En...
ISO 13347-3:2004 applies to industrial fans as defined in ISO 5801 and ISO 13349. It is limited to the determination of airborne sound emission for the specified set-ups. Vibration is not measured, nor is the sensitivity of airborne sound emission to vibration effects determined.
The sizes of fan which can be tested in accordance with ISO 13347-3:2004 are limited only by the practical aspects of…
Coal — Froth flotation testing — Part 3: Release evaluation
ISO 8858-3:2004 describes a laboratory method for release evaluation of the froth flotation characteristics of hard coal, of particle size less than 0.5 mm. It is applicable to coal in powder form or in the form of a slurry.
To develop a list of standardised core terms and definitions to be used by ISO/TC 336 Laboratory Design to enable a consistent and unambiguous understanding of the standard's requirements and its practical application.
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.
Medical electrical equipment — Clinical performance evaluation of clinical thermometers
This document specifies the requirements and methods for the clinical investigation of ME equipment used to measure the body temperature in indirect measurement mode.
This document covers both intermittently and continuously measuring clinical thermometers.
NOTE For clinical thermometers in direct measurement mode determining the technical accuracy in accordance with IEC 80601-2-56 is…
Reciprocating internal combustion engines — Measurement method for exhaust silencers — Sound power l...
ISO 15619:2013 specifies the measurement method and requirements for exhaust silencers which is installed on reciprocating internal combustion engines, including laboratory measurement and site measurement.
Truck and bus tyres — Verifying tyre capabilities — Laboratory test methods
Of the test methods presented (strength test for the structure, endurance test), only some may be required depending on the type of tyre to be tested. The tests are carried out in a laboratory under controlled conditions. Applies to all truck and bus tyres.
