Fans — Determination of fan sound power levels under standardized laboratory conditions — Part 1: Ge...
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.
Corrosion of metals and alloys — Corrosion and fouling in industrial cooling water systems — Part 2:...
ISO 16784-2:2006 applies to corrosion and fouling in industrial cooling water systems
ISO 16784-2:2006 describes a method for preliminary evaluation of the performance of treatment programmes for open recirculating cooling water systems. It is based primarily on laboratory testing but the heat exchanger testing facility can also be used for on-site evaluation. ISO 16784-2:2006 does not include…
Plastics — Methods of exposure to laboratory light sources — Part 1: General guidance and requiremen...
ISO 4892-1:2016 provides information and general guidance relevant to the selection and operation of the methods of exposure described in detail in subsequent parts. It also describes general performance requirements for devices used for exposing plastics to laboratory light sources. Information regarding performance requirements is for producers of artificial accelerated weathering or artificial…
Sludge recovery, recycling, treatment and disposal — Protocol for validating methods for physical pr...
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.
Sludge recovery, recycling, treatment and disposal — Laboratory chemical conditioning procedure
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.
Biotechnology — Massively parallel sequencing — Part 3: General requirements and guidance for metage...
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…
Measurement of radioactivity in the environment — Bioindicators — Part 1: General guide for the samp...
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.
Plastics — Methods of exposure to laboratory light sources — Part 3: Fluorescent UV lamps
ISO 4892-3:2016 specifies methods for exposing specimens to fluorescent UV radiation, heat and water in apparatus designed to simulate the weathering effects that occur when materials are exposed in actual end-use environments to global solar radiation, or to solar radiation through window glass.
The specimens are exposed to fluorescent UV lamps under controlled environmental conditions (…
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.
