This document contains technical safety requirements for the design, equipment and testing of brushless vehicle washing systems and vehicle washing systems with brushes for, indoor and outdoor operation, i.e. roll-over vehicle washing systems, vehicle washing tunnels, manually movable vehicle washing facilities. NOTE 1 Annex D covers the determination and control of Legionella and Pseudomonas aeruginosa concentration in stationary vehicle wash systems. Additionally, it can be applied to all vehicle washing systems that can form aerosols due to their cleaning systems. This document does not apply to hand-guided high pressure cleaners which are covered by EN 60335 2-79:2012, to water recycling systems, buildings and doors for entering the traffic zone, for powered ride-on machines and powered walk-behind machines with a traction drive. This document does not apply to bicycle cleaning systems. NOTE 2 Signals (example doors, lighting systems) can be provided by the vehicle washing system. This document contains requirements for the protection of persons and objects from accidents and damages during use and operation of vehicle washing systems. Persons to be protected are: - operators, - maintenance and monitoring personnel, - persons in the vicinity of vehicle washing systems, - persons sitting in the vehicle during cleaning. Objects to be protected are: - vehicles. Significant hazards associated with vehicle washing systems are listed in Clause 4. These hazards have been established by a risk assessment according to EN ISO 12100 and require measures to eliminate the hazard or to reduce the risk. These measures are specified in Clause 5 of this document. The safety requirements assume that vehicle washing systems are regularly maintained by trained and competent persons according to the manufacturer's information and that the operators, with the exception of users of self-service washing systems, have been instructed in the handling of vehicle washing systems.

Elektroninės sąskaitos faktūros. 1 dalis. Elektroninės sąskaitos faktūros pagrindinių elementų semantinis duomenų modelis

This European Standard establishes a semantic data model of the core elements of an electronic invoice. The semantic model includes only the essential information elements that an electronic invoice needs to ensure legal (including fiscal) compliance and to enable interoperability for cross-border, cross sector and for domestic trade. The semantic model may be used by organizations in the private and the public sector for public procurement invoicing. It may also be used for invoicing between private sector enterprises. It has not been specifically designed for invoicing consumers. This European Standard complies at least with the following criteria: - it is technologically neutral; - it is compatible with relevant international standards on electronic invoicing; - the application of this standard should comply with the requirements for the protection of personal data of Directive 95/46/EC, having due regard to the principles of privacy and data protection by-design, data minimization, purpose limitation, necessity and proportionality; - it is consistent with the relevant provisions of Directive 2006/112/EC [2]; - it allows for the establishment of practical, user-friendly, flexible and cost-efficient electronic invoicing systems; - it takes into account the special needs of small and medium-sized enterprises as well as of sub-central contracting authorities and contracting entities; - it is suitable for use in commercial transactions between enterprises.

Geležinkelio taikmenys. Stabdymas. Stabdžių eksploatacinės charakteristikos

This document defines a harmonized way to assess the braking performance by test of locomotives, passenger coaches, freight wagons, railbound construction and maintenance machines, and self-propelled passenger trains (multiple units) including high speed trains. The document sets out the standardized method for undertaking brake performance tests and the correction factors to be applied to the data obtained for all types of rolling stock. This document also defines the methods to assess the brake performance in terms of stopping distance, and from this the process to determine vehicle(s) deceleration and braked weight. It then deals with conversion of the braked weight to the braked weight percentage of a vehicle or train for operating purposes. It also sets out additional factors when determining the braked weight percentage of a train calculated from specified braked weight, depending on the formation of the train. In Annex D there is a method for determining brake performance of freight wagons fitted with P10 cast iron or LL-blocks using limited testing (force measurement).
