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.
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.
This document specifies requirements and test methods for powered polymerization activators in the 380 nm to 515 nm wavelength region intended for chairside use in polymerization of dental polymer-based materials.
This document applies to quartz-tungsten-halogen lamps and light-emitting diode (LED) lamps. Powered polymerization activators could have internal power supply (rechargeable battery…
Protective clothing for firefighters — Laboratory test methods and performance requirements for wild...
This document specifies methods of test and minimum performance requirements for personal protective clothing, designed to protect the wearer's body, except for the head, hands, and feet, that is worn during wildland firefighting and associated activities. This clothing is not intended to provide protection during fire entrapment. This document covers the general design of the garment, the…
Water quality — Sampling — Part 15: Preservation and handling of samples of sludge, sediment and sus...
ISO 5667-15:2009 provides guidance on procedures for the preservation, handling and storage of samples of sewage and waterworks sludge, suspended matter, saltwater sediments and freshwater sediments, until chemical, physical, radiochemical and/or biological examination can be undertaken in the laboratory.
The procedures in ISO 5667-15:2009 are only applicable to wet samples of sludge, sediment…
Solar energy — Calibration of a pyranometer using a pyrheliometer
Its use is mandatory for the calibration of secondary standard pyranometers according to ISO 9060, and is recommended for the calibration of pyranometers which are used as reference instruments in comparisons. Is intended for use by test institutions or test laboratories equipped with well-maintained pyrheliometers and is applicable to all pyranometers. The object is to promote the uniform…
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.
