ISO 13347-4:2004 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 the fan, which can be tested in accordance with ISO 13347-4:2004, are limited only by the practical…

ISO 16071:2015 specifies the test method, the reagents, and the procedure to be used in an accelerated atmospheric corrosion test constituting a 6 h exposure to a slightly acidified solution of 1 % NaCl twice weekly, followed by a condition of controlled humidity cycling between 95 % RH and 50 % RH at a constant temperature of 35 °C. It does not specify the dimensions of the tests specimens, the…

This International Standard specifies test methods for determining the physical properties of synchronous belts used in driving engine parts, such as camshafts, fuel injection pumps, balancing shafts. These test methods are intended to provide a means of characterizing synchronous belt properties for belts which are evaluated and qualified by dynamic laboratory and field testing. NOTE The…

ISO 13347:2004 deals with the determination of the acoustic performance of industrial fans. In addition, it may be used to determine the acoustic performance of fans combined with an ancillary device such as a roof cowl or damper or, where the fan is fitted with a silencer, the sound power resulting from the fan and silencer combination.

This international standard is intended to provide a protocol for the interlab validation of methods for the characterization of sludge/biosolids physical properties considered that in most cases fresh sludge samples cannot be circulated to several laboratories in different countries for validation purposes as uncontrolled variations of their characteristics would occur.

This international standard specifies a chemical conditioning procedure for sludge/biosolids thus allowing results obtained in different places and laboratories, and on different times to be compared when selecting type and dosage of a conditioning product at laboratory scale.

This document specifies general requirements and guidance for metagenomics-dedicated sample preparation, generating and analyzing metagenomics sequence data obtained from massive parallel sequencing platforms. The specified metagenomics process includes the following stages: a) Sampling strategy and process, including type, storage, transportation, extraction, quality; b) Nucleic acid library…

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.

This document describes the general principles pertaining to the sampling strategy, to the collection and conditioning of samples, to their transport to the laboratory and to the pre-treatment operations to be carried out prior to analysis.
