and testsNOTESee 5.1.3 and EN 837-1.5.1.2 Compliance and conformityA visual and measurement check shall be made with one sample to determine that the component corresponds to thedescription in the drawings, parts lists, description of functions, operating and installation instructions.5.1.3 CorrosionOne sample shall be conditioned in accordance with 5.2.8 followed by an accuracy check in accordance withEN 837-1.SIST EN 12094-10:2003

C and (++5002) °C after conditioning at the testtemperature for (2 ± 0,5) h.5.2.8 CorrosionA specimen shall be suspended freely in its normal installation attitude.The test set-up comprises a container 5 l in volume, made of heat-resistant glass and with a corrosion-resistantcover which is shaped to prevent condensate dripping onto the specimen. (If a container 10 l in volume is used, thequantities of chemicals given below shall be doubled.) The container is heated electrically and the side walls arecooled with water. A thermostat regulates the heating so as to maintain a temperature of approximately 45 °Cinside the container. During testing water is passed through a cooling coil wrapped around the container, it shallflow fast enough that its temperature at the discharge point is below 30 °C.The combination of heating and cooling is designed to ensure that vapours will condense on the surface of thespecimen. The sulphur dioxide atmosphere is generated in the 5-litre container with a solution of 20 g of sodiumthiosulphate (Na2S2O3 x 5H2O) in 500 cm3 of distilled water, to which 20 cm3 of dilute sulphuric acid is addeddaily. The dilute sulphuric acid comprises 128 cm3 of one molar sulphuric acid (H2SO4) dissolved in 1 l of distilledwater. The test specimen shall be removed from the container after 8 days; the container shall be cleaned. Thenthe procedure described above is repeated for a further period of 8 days.After a total of 16 days, the specimen is removed from the container and allowed to dry for seven days at atemperature of (20 ± 5) °C at maximum relative humidity of 70 %.6 MarkingPressure gauges shall be marked in accordance with EN 837-1:1996, 9.6.7.Pressure switches shall be marked with:a) name or trademark of the manufacturer or supplier;b) model designation (type);c) some mark(s) or code(s) (e.g. serial number or batch code), by which, at least, the date or batch and place ofmanufacture (if several places of manufacture) can be identified by the manufacturer; andd) set-point pressure.The markings shall be non-detachable, non-flammable, permanent and legible.Where the requirements of ZA.3 give the same information as above, the requirements of this clause 6 have beenmet.SIST EN 12094-10:2003
