This European Standard specifies a communication protocol for networked control systems. The protocol provides peer-to-peer communication for networked control using web-services. The standard describes services in layer 2 and layer 3. The layer 2 (data link layer) specification also describes the MAC sub-layer interface to the physical layer. The physical layer provides a choice of transmission media. The layer 3 (network layer), as described in EN 14908-1, is integrated in UDP/IP communication using IPv4 and IPv6 protocols.

This document: - specifies methods for the measurement of airborne and structure-borne sound produced in waste water and rain water installations under laboratory conditions; - defines the expression of the results. It is applicable to waste water piping systems and parts thereof, but not to the actual sources of the wastewater, e.g. lavatories, toilets and bathtubs or any active units. It applies to pipes with natural ventilation and made of any common material in commonly used diameters (up to 150 mm). The results obtained can be used for the comparison of products and materials. It may serve in estimating the behaviour of waste water systems in a building under certain conditions. Nevertheless, this standard does not provide a normalized procedure for calculating the acoustical properties of such installations in a building. This revision will also consider the effect of an enclosure.

This procedure is a method for evaluating the carbonation resistance of concrete using test conditions that accelerate the rate of carbonation. After a period of preconditioning, the test is carried out under controlled exposure conditions using an increased level of carbon dioxide. NOTE The test under reference conditions takes a minimum of 112 days comprising a minimum age of the specimen prior to conditioning of 28 days, a minimum conditioning period of 14 days and an exposure to increased carbon dioxide levels of 70 days. This procedure is not a method for the determination of carbonation depths in existing concrete structures.

This European Standard specifies methods for the calculation of the thermal and fluid dynamic characteristics of chimneys serving one heating appliance. The methods in this part of this European Standard are applicable to negative or positive pressure chimneys with wet or dry operating conditions. It is valid for chimneys with heating appliances for fuels subject to the knowledge of the flue gas characteristics which are needed for the calculation. The methods in this part of this European Standard are applicable to chimneys with one inlet connected with one appliance. The methods in Part 2 of this European Standard are applicable to chimneys with multiple inlets and one inlet with multiple appliances. Part 3 describes methods for the development of diagrams and tables for chimneys serving one heating appliance.

This part of EN 13384 specifies methods for calculation of the thermal and fluid dynamic characteristics of chimneys serving more than one heating appliance. This part of EN 13384 covers both the cases, either a) where the chimney is connected with more than one connecting flue pipe from individual or several appliances in a multi-inlet arrangement; or b) where the chimney is connected with an individual connecting flue pipe connecting more than one appliance in a cascade arrangement. The case of multiple inlet cascade arrangement is covered by the case a). This part of EN 13384 deals with chimneys operating under negative pressure conditions (there can be positive pressure condition in the connecting flue pipe) and with chimneys operating under positive pressure conditions and is valid for chimneys serving heating appliances for liquid, gaseous and solid fuels. This part of EN 13384 does not apply to: - chimneys with different thermal resistance or different cross-section in the various chimney segments. This part does not apply to calculate energy gain; - chimneys with open fire places, e.g. open fire chimneys or chimney inlets which are normally intended to operate open to the room; - chimneys which serve different kinds of heating appliances regarding natural draught, fan assisted, forced draught or combustion engine. Fan assisted appliances with draught diverter between the fan and the chimney are considered as natural draught appliances; - chimneys with multiple inlets from more than 5 storeys. (This does not apply to balanced flue chimney.); - chimneys serving heating appliances with open air supply through ventilation openings or air ducts, which are not installed in the same air supply pressure region (e.g. same side of building). For positive pressure chimneys this part only applies if any heating appliance which is out of action can be positively isolated to prevent flue gas back flow.

This European Standard specifies requirements and test methods for rain caps that are used as components, subject to flue gas, in order to prevent rain entry into the chimneys. Rain caps already tested together with system chimney products or other chimney components, e.g. terminals, are not covered by this standard. Rain caps incorporating a bird guard are also included. It also specifies the requirements for marking, manufacturers’ instruction, product information and evaluation of conformity.

This European standard specifies the requirements and test methods for flue dampers that are used as components, carrying flue gas, in order to limit the flow in a chimney. Flue dampers may be manually adjusted, sited in connecting flue pipes or chimneys, in order to reduce the burning rate (solid fuel stoves/fireplaces) or to work as a shut-off slide preventing back flow of soot during cleaning of the chimney, or mechanically driven for reducing/closing the flue, in order to reduce the Stand-by losses or to prevent the backflow of the flue gas e.g. in case of multi-served chimneys. This European standard covers only flue dampers incorporated in a housing and installed inside a building. Flue dampers already tested together with system chimney products or other chimney components, e.g. flue liners, connecting flue pipes, are not covered by this standard. This European standard also specifies the requirements for marking, manufacturers’ instruction, product information, Assessment and Verification of Constancy of Performance (AVCP), cleaning and maintenance.
