Water quality — Determination of acute lethal toxicity to marine copepods (Copepoda, Crustacea)
This International Standard describes a method for the determination of the acute toxicity to one of three specified
species of marine copepod (Copepoda, Crustacea) of
a) chemical substances which are soluble, or can be maintained as a stable suspension or dispersion, under the
conditions of the test;
b) industrial or sewage effluents, treated or untreated, after decantation, filtration or…
Agricultural vehicles — Mechanical connections on towed vehicles — Dimensions for hitch rings
This International Standard specifies dimensional requirements for the attachment of agricultural, non-balanced
trailers and implements by means of hitch rings to the rear of towing vehicles equipped with a hook specified in ISO
6489-1. Its purpose is to ensure the interchangeability of the mechanical connections on agricultural towed
vehicles.
This International Standard is applicable to rings…
Meteorology — Radiosonde — Part 3: Laboratory test method for solar radiation error of temperature s...
This International Standard proposal specifies technical requirements and evaluation method for temperature correction on temperature measurement in radiosonde due to solar radiation in sounding experiment. This International Standard is applicable to the correction of temperature measurement traceable to SI unit in radiosonde boom sensors according to variations of pressure and air speed under…
Meteorology — Radiosonde — Part 2: Laboratory test method for errors in radiosonde humidity sensor c...
The purpose of this International Standard is to provide a test method for the calibration of radiosonde humidity sensors with varying temperature and relative humidity using laboratory setups. The main scope of this International Standard is as follows:
a) Technical requirements for laboratory setups needed for the calibration of radiosonde humidity sensors.
b) Test procedure for calibrating…
Spices and condiments — Preparation of a ground sample for analysis
Basis for this method is the laboratory sample obtained by the method specified in ISO 948. The principle of determination consists in grinding the laboratory sample, which has been previously mixed, to obtain particles of the size specified in the International Standard appropriate to the spice or condiment concerned or, if not so specified, to obtain particles of size approximately 1 mm.
Space systems — Solar cells — Calibration procedures
This document specifies the requirements for primary and secondary calibration procedures of single-junction and multi-junction space solar cells. The main body of this international standard specifies the requirements for Air Mass Zero (AM0) standard primary and secondary calibration.
Presentation of Lexicographic Entries in General Language Dictionaries – Fundamentals and Recommenda...
This international standard focuses on the presentation of lexicographic articles in language dictionaries, either monolingual, bilingual or multilingual, following a lexicographic lemma-oriented approach, being addressed for human end-users. Concerning the modelling of the underlying data, the ISO 1951:2007 follows the ISO 24613 series.
The document provides recommendations to deal with the…
Industrial systems, installations and equipment and industrial products — Structuring principles and...
This part of 81346 International Standard, published jointly by IEC and ISO, provides, in combination
with IEC 81346-1 and IEC 81346-2, rules and recommendations on the structuring of systems and
the information on systems in area of technical products and equipment of manufacturing systems.
It also provides classification scheme of infrastructure objects in such system for use in function -…
