This document specifies the minimum requirements for the safe and independent access and use of lifts by persons, including persons with disabilities. It covers the needs of persons with disabilities according to Annex A. NOTE For guidance on solutions for increased accessibility and usability, see Annex D.

This document specifies requirements and tests for the construction, performance and safety of class 1,5 Capillary Thermal-Mass Flow sensor gas meters (hereinafter referred to as meter(s)). This applies to meters having co-axial single pipe, or two pipe connections, that are used to measure volumes of fuel gases of the 2nd and/or 3rd family, as given in EN 437:2018. In general, the term "thermal mass flow meters" applies to a flow-measuring device using heat transfer to measure and indicate gas flowrate, as defined in ISO 14511. NOTE 1 Although the word "mass" is present in the definition of the measurement principle, gas meters covered by this document provide measurement of gas at base conditions of temperature and pressure. These meters have a maximum working pressures not exceeding 0,5 bar and a maximum flowrate not exceeding 160 m3⋅h−1 over a minimum ambient temperature range of −10 °C to +40 °C and a gas temperature range as specified by the manufacturer with a minimum range of 40 K. This document applies to meters indicating volume at base conditions, which are installed in locations with vibration and shocks of low significance. It applies to meters in: - closed locations (indoor or outdoor with protection, as specified by the manufacturer) with condensing humidity or with non-condensing humidity; or, if specified by the manufacturer: - open locations (outdoor without any covering) both with condensing humidity or with non-condensing humidity; and in locations with electromagnetic disturbances likely to be found in residential, commercial and light industrial use. For meters which indicate unconverted volume reference can be made to Annex C. Unless otherwise stated, all pressures given in this document are gauge pressures. Requirements for electronic indexes, valves and additional requirements for batteries incorporated in the meter and any other additional functionalities are given in EN 16314:2013. Unless otherwise stated in a particular test, the tests are carried out on meters that include additional functionality devices intended by the manufacturer. Clauses 1 to 13 are for design and type testing only.

This document references existing quality and test methodologies for recycled PVC to be used in PVC-U profiles for windows and doors. It contains a description of the controlled loop as such, the definition of those material transformation steps which are relevant for product quality, in particular recycling input and output and profile manufacturing input and output. Traceability tools are specified to characterize this loop as a controlled loop. With regard to PVC waste treatment, the present document relates to existing standards such as EN 15343, EN 15346 and EN 15347. With regard to semifinished and/or finished products, it refers to the European Standard PVC-U window profiles (see EN 12608 1) and to the European Standards for windows and doors (see EN 14351 1, EN 14351-2 and EN 16034). The controlled loop treatment of PVC profiles will be aligned to the general understanding of life cycles as outlined in EN 15804.

This document specifies: - the dimensional, mechanical, hydraulic and acoustic characteristics with which sanitary tapware aerators (with and without flow regulation) should comply; - the procedures for testing these characteristics. This document is applicable to: - Sanitary tapware aerators intended to be mounted on tapware used with sanitary appliances in toilets, bathrooms and kitchens (e.g. single taps, combination tap assemblies, mechanical mixing valves, thermostatic mixing valves); —-Sanitary tapware aerators used under the following pressure and temperature conditions: Note 1: Sanitary tapware aerators can only be connected downstream of the obturator of the sanitary tapware product. Note 2: For the purposes of brevity, sanitary tapware aerators will be detailed only as aerators in the rest of this document. Note 3: The tests described in this document are type tests (laboratory tests) and not quality control tests carried out during manufacture.

This document specifies data exchange and communications for meters in a generic way. This document establishes a protocol specification for the Application Layer for meters and establishes several protocols for meter communications which can be applied depending on the application being fulfilled. This document also specifies the overall structure of the OBject Identification System (OBIS) and the mapping of all commonly used data items in metering equipment to their identification codes.” NOTE Electricity meters are not covered by this document, as the standardization of remote readout of electricity meters is a task for CENELEC/IEC.

This document deals with Portland-composite cement CEM II-C/M, not covered by EN 197-1, and a new type of Composite cement CEM VI, also not covered by EN 197-1, whose intended use is the preparation of concrete, mortar, grout etc. This document does not cover: - common cement covered by EN 197-1; - very low heat special cement covered by EN 14216; - supersulfated cement covered by EN 15743; - calcium aluminate cement covered by EN 14647; - masonry cement covered by EN 413-1.
