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.
Food products — Characteristics of fresh and dry baker’s yeast
This document specifies characteristics of fresh and dry baker’s yeast, particularly those relating to general product properties, application performance, physical and chemical properties, microbiology, and nutritional value information. This document is primarily intended for use by the baking industry, but is also aimed at laboratory and food testers
