1 Scope This European Standard applies to winter service machines which are defined in clause 3. This European Standard deals with all significant hazards (see clause 4) identified through a risk assessment pertinent to winter service machines when they are used as intended and under the conditions foreseen by the manufacturer. This European Standard does not deal with significant hazards […]

6.2 Steady-state conditions 6.2.1 Steam pressure, steam and feed water temperature or, for hot water generator, the flow and return temperatures, together with the relevant flow rates, shall be held as steady as possible and at levels close to normal operating conditions. These measurements shall be taken at the boiler exit or as closed as practical at the (same) test […]

1 Scope This Part of this European Standard applies to all water-tube boilers as defined in EN 12952-1 which are heated by combustion of one or more fuels or by hot gases for the generation of steam and/or hot water. This Part of this European Standard applies to those components between the feedwater inlet and the steam outlet of the […]

5 Requirements 5.1 Steam boiler 5.1.1 Each steam boiler and each isolatable heated compartment (e.g. reheater, superheater, economizer) shall be provided with at least one suitable safety device which shall ensure against excessive pressure. The total certified discharge capacity of all safety devices mounted on the boiler shall be at least equal to the maximum continu- ous rating (MCR) of […]

1 Scope This European Standard gives specific procedures for industrial X-radiation and gamma radiography for discontinuity detection purposes, using film techniques. These procedures are applicable to castings produced by any casting process, especially for steel, cast iron, magnesium, zinc, copper, nickel, aluminium, titanium and any alloys of them. This European Standard does not apply to: the testing of welded joints; […]

1 Scope This European Standard specifies the requirements for the ultrasonic examination of steel castings (with ferritic structure) for highly stressed components and the methods for determining internal discontinuities by the pulse echo technique. This European Standard applies to the ultrasonic examination of steel castings which have usually received a grain refining heat treatment and which have wall thicknesses up […]

1 Scope This European Standard specifies a method, based on EN ISO 8990 and EN ISO 12567-1, to measure the thermal transmittance of frame and sash components of windows and doors, including mullions and transoms. The thermal bridging effect of window or door components (handles, hinges, closing devices, etc.) is included. The test procedure is designed to take into account […]

1 Scope This Part of this European Standard specifies the particular materials, manufacturing and testing requirements for stranded steel wire ‘hauling’ and ‘carrying-hauling’ ropes for cableway installations designed to carry persons. The particular hazards covered by this Part are identified in Clause 4. The rope grade is limited to 1960. Minimum breaking forces for the more common classes, sizes and […]

1 Scope This European Standard specifies a test method for the design of slurry mix based on the determination of the minimum binder content of the mix under wet track abrasion conditions. This European Standard applies to slurry surfacing to be used in surface layers. NOTE For some course mixtures the precision is poor due to loss of aggregates comes […]

1Scope This European Standard contains definitions of termsrelated to scrap of aluminium and aluminium alloyswhich are helpful for the communication within the aluminium industry and between the industry and theauthorities. Definitions of general terms which are helpful for thecommunication within the aluminium industry are laiddown in EN 12258-1. NOTE1ln some terms and definitions “aluminium” isused for “”aluminium and aluminium alloys”. […]
