ISO/IEC 17067:2013 describes the fundamentals of product certification and provides guidelines for understanding, developing, operating or maintaining certification schemes for products, processes and services. ISO/IEC 17067:2013 is intended for use by all with an interest in product certification, and especially by certification scheme owners.
This document describes integrated measurement methods for short-lived radon‑222 decay products. It gives indications for measuring the average potential alpha energy concentration of short‑lived radon-222 decay products in the air and the conditions of use for the measuring devices. This document covers samples taken over periods varying from a few weeks to one year. This document is not applicable to systems with a maximum sampling duration of less than one week. The measurement method described is applicable to air samples with potential alpha energy concentration of short-lived radon-222 decay products greater than 10 nJ/m3 and lower than 1 000 nJ/m3. NOTE For informative purposes only, this document also addresses the case of radon-220 decay products, given the similarity in behaviour of the radon isotopes 222 and 220.
This document specifies the dimensional requirements and location for a ball coupling device of 80 mm nominal diameter, whose male part is fitted to an agricultural towing vehicle and female part is fitted to a towed, non-balanced vehicle which provides mechanical connection between the two vehicles. It defines vertical loading for different positions. This document specifies a ball coupling device with either a horizontal adjustable version, or a close position version.
This document defines the construction, safety, and performance requirements of modular or factory-matched hydrogen gas generation appliances, herein referred to as hydrogen generators, using electrochemical reactions to electrolyse water to produce hydrogen. This document is applicable to hydrogen generators that use the following types of ion transport medium: — group of aqueous bases; — group of aqueous acids; — solid polymeric materials with acidic function group additions, such as acid proton exchange membrane (PEM); — solid polymeric materials with basic function group additions, such as anion exchange membrane (AEM). This document is applicable to hydrogen generators intended for industrial and commercial uses, and indoor and outdoor residential use in sheltered areas, such as car-ports, garages, utility rooms and similar areas of a residence. Hydrogen generators that can also be used to generate electricity, such as reversible fuel cells, are excluded from the scope of this document. Residential hydrogen generators that also supply oxygen as a product are excluded from the scope of this document.
This document provides an overview of smart contracts in BC/DLT systems; describing what smart contracts are and how they work. It also discusses methods of interaction between multiple smart contracts. This document focuses on technical aspects of smart contracts. Smart contracts for legally binding use and applications will only be briefly mentioned in this document.
This document specifies the conditions required for good keeping of the following groups of citrus fruits during their storage with or without refrigeration, in stores or in various transport equipment (such as containers, railway cars, trucks or ships): — oranges: Citrus sinensis (Linnaeus) Osbeck; — mandarins: Citrus reticulata Blanco; — lemons: Citrus limon (Linnaeus) N. L. Burman; — grapefruits: Citrus paradisi Macfadyen; — limes: — Citrus aurantifolia (Christmann) Swingle; — Citrus latifolia Tanaka. Detailed information concerning cultivars in these different groups is given in Annexes A and B.
This document specifies two methods (high-temperature combustion and high-pressure vessel combustion) for the determination of chlorine in solid mineral fuels. It is applicable to solid mineral fuels. The chlorine in the absorption solution can be determined using different finishes, such as coulometric or potentiometric titration, spectrophotometry or ion chromatography. The method is applicable to determine the chlorine content higher than 0,005 % mass fraction.
This document defines a description of common terms and symbols used in the field of bicycles and two wheeled Electric Power Assisted Cycles (EPACs). The terms are classified under a nomenclature of different parts of bicycles and two wheeled EPACs, and presented in several languages.
This document specifies requirements for establishing, implementing and maintaining prerequisite programmes (PRPs) for transport and storage in the food chain to assist in controlling food safety hazards. This document is applicable to all organizations, regardless of size or complexity, that are involved in transport and storage activities across the food supply chain and that wish to implement PRPs in such a way as to address the requirements specified in ISO 22000. This document is neither designed nor intended for use in other parts of the food supply chain or in isolation. In this document, transport and storage is aligned with ISO/TS 22003:2013, Annex A, Category G. This document includes all food and feed products and food packaging and packaging materials. Live animals are excluded from the scope of this document except when intended for direct consumption, e.g. molluscs, crustaceans and live fish.
