This document describes a test method for the determination of the compressive strength of specimens of hydraulically bound mixtures. This document applies to specimens manufactured in the laboratory or prepared from cores.

This document provides requirements and test methods for flexible, factory made, buried district heating pipe systems with metallic service pipes and bonding between the layers of the pipe assemblies and thermal insulation materials of polyurethane or polyisocyanurate foam, the casing being made of polyethylene.It shall be used in conjunction with part 1.This document is valid for maximum media temperatures up to 120 °C and, occasionally peak temperatures up to 140 °C for maximum 300 h/a, and a design pressure up to 2,5 MPa for a design lifetime of at least 30 years.This document covers surveillance systems.In conjunction with the other parts of EN 15632, this document is applicable to pipes, fittings, their joints and to joints with components made of non-plastics materials intended to be used for district heating installations.NOTE For higher temperatures or for the transport of other fluids, for example potable water, additional requirements and testing is needed. Such requirements are not specified in this document.

This European Standard provides requirements and test methods for flexible, pre-insulated, directly buriedheating pipes with plastics service pipes and bonding between the layers of the pipes.This European Standard is valid for maximum operating temperatures of 95 °C and maximum operatingpressures up to 10 bar for a design lifetime of at least 30 years.This European Standard does not cover surveillance systems.NOTE For higher temperatures or for the transport of other fluids, for example potable water, additional requirementsand testing is needed. Such requirements are not specified in this European Standard.

This document provides classification, general requirements and test methods for flexible, factory made, buried district heating pipe systems.This document is intended to be used in conjunction with part 2, 3 or 4, as applicable.Depending on the pipe assembly (see Table 4), this document is valid for maximum media temperature of 95 °C (part 2 and 3) and maximum media temperature of 120 °C (for part 4) and design pressures of 0,6 MPa to 2,5 MPa.The pipe systems are designed for a service life of at least 30 years. For pipe systems with plastic service pipes, the respective temperature profiles are defined in EN 15632-2 and EN 15632-3.NOTE For the transport of other liquids, for example potable water, additional requirements may be applicable.

This document defines the requirements for qualification, acceptance, delivery and inspection of 100° countersunk head, 100° countersunk reduced head and protruding head close tolerance pins, shear type in aluminium alloy 7050T73 and collars of aluminium alloy 3003 and of aluminium alloy 6061T7 for use as permanent fasteners in aerospace applications.

This European Standard specifies the requirements for the installation of automotive LPG components that comply with prEN 12805 and prEN 12806.These requirements are to ensure safe operation of such components.This standard does not cover type approval of a LPG motor vehicle.NOTE Type approval requirements are covered in UN/ECE Regulations and EU legislation.

The scope for this European Standard is limited to:- payment method: Central account based on EFC-DSRC;- physical systems: OBU, RSE and the DSRC interface between them (all functions and information flows related to these parts);- DSRC-link requirements;- EFC transactions over the DSRC interface;- data elements to be used by OBU and RSE used in EFC-DSRC transactions;- security mechanisms for OBU and RSE used in EFC-DSRC transactions.
