This document provides standard procedures for the collection, handling and storage of soil for subsequent biological testing under aerobic conditions in the laboratory. It applies to the collection, handling and storage for assessing the effects of soil on microorganisms, invertebrates (e.g. survival, reproduction, growth, behaviour) and plants (e.g. development, growth). This document is not…

This document provides a system for the identification and presentation of information about freight containers. The identification system is intended for general application, for example in documentation, control and communications (including automatic data processing systems), as well as for display on the containers themselves. The methods of displaying identification and certain other data (…

1.1 This document — amplifies the general principles for designing experiments for the numerical estimation of the precision of measurement methods by means of a collaborative interlaboratory experiment; — provides a detailed practical description of the basic method for routine use in estimating the precision of measurement methods; — provides guidance to all personnel concerned with designing,…

This document applies to the basic safety and essential performance of respiratory high-flow therapy equipment, as defined in 201.3.220, hereafter also referred to as ME equipment or ME system, in combination with its accessories: —   intended for use with patients who can breathe spontaneously; and —   intended for patients who would benefit from improved alveolar gas exchange; and who would…

The ISO 11929 series specifies a procedure, in the field of ionizing radiation metrology, for the calculation of the "decision threshold", the "detection limit" and the "limits of the coverage interval" for a non-negative ionizing radiation measurand when counting measurements with preselection of time or counts are carried out. The measurand results from a gross…

ISO 11783, as a whole, specifies a serial data network for control and communications on forestry or agricultural tractors and mounted, semi-mounted, towed, or self-propelled implements. Its purpose is to standardize the method and format of transfer of data between sensors, actuators, control elements and information storage, and display units, whether mounted on, or part of, the tractor or…

ISO 24490:2016 specifies the minimum requirements for the design, manufacture and testing of centrifugal pumps for cryogenic service. ISO 24490:2016 does not apply to reciprocating pumps. This International Standard also gives guidance on the design of installations (see Annex A). It does not specify requirements for operation or maintenance. NOTE For general requirements for materials used in…

This part of ISO 23611 provides guidance for the design of field studies with soil invertebrates (e.g. for the monitoring of the quality of a soil as a habitat for organisms). Detailed information on the sampling of the most important soil organisms is provided in the other parts of this International Standard (ISO 23611-1 to ISO 23611-5). This part of ISO 23611 is used for all terrestrial…

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…

This document defines measuring methods for the determination of basic measurements of surgical standard instruments. This document does not apply to instruments for use on the central nervous system and on the central cardiovascular system. NOTE 1 Instruments for use on the central nervous system and on the central cardiovascular system are measured differently due to complex geometries which…
