    Beskrivelse
    This International Standard deals with performance requirements for protective paint systems for offshore and related structures (i.e. those exposed to the marine atmosphere, as well as those immersed in sea or brackish water). Such structures are exposed to environments of corrosivity category CX (offshore) and immersion category Im4 as defined in ISO 12944-2, with special stresses as given in 4.3 and Annex B of ISO 12944-2:1998. ISO 12944-9 can also be used for other structures, provided that the paints or protective paint systems selected comply with this International Standard. This International Standard places emphasis on high-durability paint systems, with the aim of minimizing maintenance and hence reducing safety considerations and environmental impact. The temperature range applicable for these paint systems is considered to be between -20 °C and +120 °C, and the performance testing is aimed at verifying suitability of the paint systems for this temperature range. The use of paint systems outside this temperature range shall be subject to agreement by the end user. Such agreement may include testing at the applicable temperatures. The paint systems for submerged service (Im4) are aimed at ambient operating temperatures up to a maximum of 50 °C. For higher operating temperatures, specific evaluation and performance documentation is needed. The selection of performance requirements should be considered in conjunction with the cathodic protection design parameters.

    This European Standard specifies requirements for limiters (or limiting devices) which are incorporated into safety systems for water-tube boilers as defined in EN 12952-1. A limiter (or limiting device) can be either: – a safety accessory as defined in the Pressure Equipment Directive, Article 1, clause 2.1.3, and needs to include the safety logic and final actuator, or – one element of a safety system, for example, a self-monitoring water level sensor used as part of a safety accessory as defined in the Pressure Equipment Directive, Article 1, clause 2.1.3. The overall boiler protection function shall be provided in association with additional safety logic (where appropriate) and a final actuator. The design requirements and examination of functional capability for the limiters are covered in this European Standard. For an explanation of the extent of the limiter (or limiting device) see Figure A.1.

    Beskrivelse
    This European Standard describes a method to determine the friction characteristics of geosynthetics (geotextiles and geotextile-related products, geomembranes), in contact with soils, at low normal stress, using an inclining plane apparatus. This test method is primarily intended as a performance test to be used with site specific soils but may also be used as an index test with standard sand. Test data obtained for geogrids tested with a rigid support are not necessarily realistic as the results depend on the friction support.

    This standard specifies safety requirements and their verification for the design and construction of power take-off (PTO) drive shafts and their guards linking self-propelled machinery (or tractor) to the first fixed bearing of recipient machinery, by describing methods for the elimination or reduction of risks which need specific requirements. This standard concerns only the PTO drive shafts and those guards which are mechanically linked to the PTO drive shaft by at least two bearings. In addition, it specifies the type of information on safe working practices to be provided by the manufacturer. This standard does not deal with: - the guards totally covering, but not mechanically linked to the PTO drive shaft. As these devices are not at present widely established on the market, they should be dealt with in a future revision of this standard; - the mechanical characteristics of PTO drive shafts, overrun devices and torque limiters; - general hazards.

    Status
    Forslag om nyt arbejdsemne vedtaget
    Beskrivelse
    This European Standard specifies performance requirements for fluid heating solar collectors with respect to mechanical resistance to climatic loads, reaction to fire and external fire performance, weather tightness, release of dangerous substances, electrical safety, operating pressure, sound level, thermal output and collector efficiency. Fluids included are anti-freeze fluids, thermo oil, air and water which are not intended for human consumption. The intended use of the solar collector is to heat up the working fluid. This European Standard also includes provisions for assessment and verification of constancy of performance to these requirements. This European Standard covers only the solar collector consisting of its components: e.g. absorber, frame, insulation and glazing; It does not cover the fluid. It is applicable to glazed and unglazed solar collectors, flat plate solar collectors, evacuated tubular solar collectors, concentrating solar collectors, tracking solar collectors and thermal-electrical hybrid solar collectors (so called PVT collectors). It is not applicable to those solar collectors, in which the thermal storage unit is an integral part of the solar collector to such an extent, that the heat production process cannot be separated from the storage process for the purpose of making measurements of these two processes.

    Beskrivelse
    This European Standard specifies performance test methods for control equipment. Furthermore, this document contains requirements on accuracy, durability and reliability of control equipment. The tests described in this document are limited to electrically activated components delivered with or for the system by the final supplier. For the purposes of this document controller and control equipment for solar heating systems and auxiliary heaters, if part of the system, are restricted to the following: a) Controllers as: 1) system clocks, timers and counters; 2) differential thermostats; 3) multi-function controllers. b) Sensors as: 1) temperature sensors; 2) irradiance sensors (for short wave radiation); 3) pressure sensors; 4) level sensors; 5) flow meters; 6) heat meters. c) Actuators as: 1) pumps; 2) solenoid and motor valves; 3) relays. d) Combinations of controllers, sensors and actuators listed above. An additional objective of the procedures described in this document is to verify control algorithms and, together with the accuracy of sensors, to determine control parameters. In addition to verifying the functioning of a controller, its equipment and actuators, the determined parameters may be used for numerical system simulations. Typically, electrical anodes are not part of the control equipment and are not controlled by the control equipment. However, because they are electrical appliances, electrical anodes are included in this document. This document is valid for control equipment of solar heating systems for the purpose of hot water preparation and/or space heating. If the solar system is connected to or part of a conventional heating system, the validity is extended to the entire system. In combination with the standards EN 12976-1, EN 12976-2 as well as EN 12977-1, EN 12977-2, EN 12977-3 and EN 12977-4, this document is valid for e) factory made solar heating systems, f) small custom built solar heating systems, g) large custo ...
