Suomen Standardisoimisliitto SFS

This European Standard specifies requirements on construction, design, performance, marking and user information for earplugs.In particular, it specifies the sound attenuation of the earplugs, measured in accordance with EN ISO 4869-1.Ergonomic aspects are addressed by taking into account, within the requirements, the interaction between the wearer, the device and where possible the working environment in which the device is likely to be used (see Annex ZA and EN 458).

This European Standard specifies requirements for construction, design, performance, marking and user information for earmuffs attached to head protection and/or face protection devices, hereinafter referred to as ‘mounted earmuffs’.In particular, it specifies the sound attenuation of mounted earmuffs, measured in accordance with EN ISO 4869-1.Because one model of earmuffs designed to be attached to head protection and/or face protection devices can be fitted to a number of other models and sizes, this part of the standard sets out a series of physical and acoustic requirements for earmuffs when fitted to the specified model(s) or size(s) of head protection and/or face protection device.All requirements apply to earmuffs fitted to one of the specified models or sizes of head protection and/or face protection device (the basic combination). An abbreviated set of requirements apply applies to the same model of earmuffs when fitted to the other specified models or sizes of head protection and/or face protection device (the supplementary combinations).Information shall be given on the range of models of carriers tested with the earmuffs which satisfies this European Standard.Ergonomic aspects are addressed by taking into account, within the requirements, the interaction between the wearer, the device and, where possible, the working environment in which the device is likely to be used (see Annex ZA and EN 458).

This document defines assurance-related terms and establishes an organized set of concepts and relationships to form a basis for shared understanding across user communities for assurance. It provides information to users of the other parts of ISO/IEC/IEEE 15026 including the combined use of multiple parts. The essential concept introduced by ISO/IEC/IEEE 15026 (all parts) is the statement of claims in an assurance case and the support of those claims through argumentation and evidence. These claims are in the context of assurance for properties of systems and software within life cycle processes for the system or software product. Assurance for a service being operated and managed on an ongoing basis is not covered in ISO/IEC/IEEE 15026 (all parts). A variety of potential users of ISO/IEC/IEEE 15026 (all parts) exists including developers and maintainers of assurance cases and those who wish to develop, sustain, evaluate or acquire a system that possesses requirements for specific properties in such a way as to be more certain of those properties and their requirements. ISO/IEC/IEEE 15026 (all parts) uses concepts and terms consistent with ISO/IEC/IEEE 12207 and ISO/IEC/IEEE 15288 and generally consistent with the ISO/IEC 25000 series, but the potential users of ISO/IEC/IEEE 15026 (all parts) need to understand the differences from concepts and terms to which they may be accustomed. This document attempts to clarify these differences. The primary purpose of this document is to aid users of the other parts of ISO/IEC/IEEE 15026 by providing context, concepts and explanations for assurance, assurance cases and integrity levels. While essential to assurance practice, details regarding exactly how to measure, demonstrate or analyse particular properties are not covered. These are the subjects of more specialized standards of which a number are referenced and included in the Bibliography.

This document provides directions for measuring and calculating the electricity consumption of any format of digital production press, whose modes, other than production printing mode, play a significant role in the comprehensive energy consumption. It excludes digital presses designed to print substrates other than paper or plastic and conventional printing presses fitted with digital inkjet printing heads. It can be used to compare the energy efficiency figures for different machine combinations: best-quality (slowest), highest-productivity (fastest) or other alternative combinations.
