Žemės darbų mašinos. Sauga. 1 dalis. Bendrieji reikalavimai

This document specifies the general safety requirements for earth-moving machinery, hereinafter also referred to as machines, described in EN ISO 6165:2012, except horizontal directional drills. NOTE 1 Horizontal directional drills are covered by EN 16228 1 and EN 16228 3. This document gives the common safety requirements for earth-moving machinery families (see EN ISO 6165:2012, 3.4) and is intended to be used in conjunction with relevant parts of EN 474-2 to EN 474-13. These machine specific parts (EN 474 2 to EN 474−13) do not repeat the requirements from EN 474 1:2022 but supplement or modify the requirements for the family in question. NOTE 2 The requirements specified in this part of the standard are common to two or more families of earth- moving machinery. This document does not provide requirements for main electrical circuits and drives of machinery when the primary source of energy is an external electrical supply. This document does not provide performance requirements for safety related functions of control system(s). This document does not deal with towing of trailers. This document does not deal with demolition machinery. This document deals with significant hazards, hazardous situations and events relevant to earth-moving machinery, when used as intended and under conditions foreseen but also taking into account any reasonably foreseeable misuse thereof (see Annex A). The following significant and relevant hazards are not covered in this document: — Laser; — Lightning. This document specifies the appropriate technical measures to reduce risks arising from the significant hazards, hazardous situations and events during the whole foreseeable lifecycle of the machinery as described in EN ISO 12100:2010, 5.4. This document is not applicable to earth-moving machinery which are manufactured before the date of publication of this document by CEN. NOTE 3 For travelling on public roads, national traffic regulations apply (e.g. braking, steering, lighting, towing, etc.) until harmonized requirements are available.

Oftalmologinė optika. Kontaktiniai lęšiai ir jų priežiūros priemonės. Konservantų sugerties ir išskyrimo nustatymas (ISO/DIS 11986:2025)

ISO 11986:2017 provides general procedures for the selection of methods, preparation of samples, and the conduct of testing for the uptake and release of preservatives from contact lenses. NOTE 1 Due to the manifest difficulties of reproducibility when coating contact lenses with mineral and organic deposits encountered during lens wear, these methods are only applicable to new and unused contact lenses. NOTE 2 Preservative depletion by a contact lens in the limited volume of a lens case could compromise disinfection performance. This document does not measure disinfection performance.

Komentavimo iki data 2025-07-03

Neardomieji bandymai. Neardomųjų bandymų personalo regos aštrumo įvertinimas (ISO/DIS 18490:2025)

ISO 18490:2015 specifies the form of the optotype, the quality requirements for the chart, the test procedure, and the acceptance level for near vision acuity of NDT personnel. It also addresses the qualification requirements for personnel permitted to carry out the test. ISO 18490:2015 only addresses near vision acuity under defined conditions similar to those encountered during routine NDT inspection. It does not address an individual's overall visual acuity and users are advised to consider the need for a general eye examination by specialist medical personnel to ensure general vision acuity is appropriate for job function. ISO 18490:2015 does not address colour vision requirements.

Komentavimo iki data 2025-07-01

Visureigiai krautuvai. Saugos reikalavimai ir patikrinimas. 7 dalis. Elektrinės sistemos

This document specifies electrical safety requirements for electrical systems of rough-terrain variable-reach trucks and slewing rough-terrain variable-reach trucks powered by one or more electric motors (hereafter referred to as trucks), namely pure electric and hybrid electric trucks, including when hydraulic systems are electrically powered. This document applies to electrical systems with maximum voltage greater than 32 up to 1500 V DC or greater than 21 up to 1000 V AC r.m.s. This document deals with all significant hazards, hazardous situations and events relevant to the trucks when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer. The significant hazards (see EN ISO 12100:2010, Annex B) dealt with in this document are listed in Annex A. This document does not deal with hazards which could occur: - during construction; - when operating trucks in potentially explosive atmospheres. This document does not cover: - electrical systems of trucks with maximum working voltage up to 32 V DC or 21 V AC r.m.s (see relevant requirements in EN 1459-1 or EN 1459-2, as applicable); - electric regenerative braking systems; - electrical systems of externally-powered trucks designed for operation only when mains-connected. NOTE Electrical systems of trucks designed to be both externally-powered and self-propelled are covered in this document when not mains-connected. This document does not deal with sales literature. This document does not address hazards specifically related to: - trucks designed to operate with varying levels of autonomy (autonomous trucks), including trucks which move autonomously to the charging station, or when truck has embedded safety-systems with fully or partially self-evolving behaviour or logic using machine learning approaches; - trucks with communication network connection. This document is not applicable to trucks manufactured before the date of its publication.

Laboratorijose naudojami vietinio ištraukimo įtaisai. Lankstinės siurbiamosios žarnos. 2 dalis. Perdavimas naudoti ir bandymas vietoje

This document applies to test methods designed to be used at the place of installation of the AEA, usually a laboratory and for various laboratory applications that require local extraction. They are used for commissioning after installation, for maintenance and for qualification purposes. For certain customer requirements additional or modified test methods can be necessary. This document includes product functional performance referring to product standard detailed in EN 16589-1. Occupational health and safety assessments methods are not included in this document. This document does not consider performance requirements for the extract air system associated with the AEA installation and therefore extract system performance is not part of the scope. This document does not confirm or establish a capture zone of an AEA capture device only the functional extract capacity and mechanical functions of the AEA.

This document describes test methods and methods for classification of wood and wood-based products for which a stage in the production process results in an improvement of the reaction-to-fire classification in accordance with EN 13501-1 for use in interior and exterior situations (use classes 1, 2, and 3 as defined in EN 335:2013). NOTE The classes of this document are not performance classes and do not give guidance for how long the reaction to fire classification of wood or wood-based product will last. This document applies to - wood and wood-based products (specific wood species, wood treated with preservatives and modified wood, for example thermally and chemically modified wood) that have been treated with fire-retardant chemical(s) applied either by a penetrating process or by a superficial process, such as with a film forming fire-retardant coating. - wood-based products that incorporate fire retardant chemical(s) as part of the production process. This document also covers fire-retardant wood and wood-based products that have a non-fire-retardant coating. Mechanical properties, aesthetic properties, dimensional stability properties, service life and biological durability of fire-retardant wood and wood-based products are not covered by this document. NOTE 2 This document is relevant for, but not limited to, products covered by these products standards: EN 13986, EN 14081-1, EN14374, EN 14915 and EN 16351.
