    Voorbeeldzinnen

    1. If water is removed by condensation, the sample gas temperature or dew point shall be monitored either within the water trap or downstream.
    2. The humidity must be maintained to a dew point of 282,5 K ± 3 K (9,5 °C ± 3 °C) and a relative humidity of 45 % ± 8 %.
    3. For sensitive balances, it is recommended that the tolerance for the weighing chamber room air temperature and the dew point be ± 1 K.
    4. Ha may be derived from relative humidity measurement, dew point measurement, vapour pressure measurement or dry/wet bulb measurement using the generally accepted formulae.
    5. The humidity shall be maintained to a dew point of 282,5 K ± 3 K (9,5 oC ± 3 oC) and a relative humidity of 45 per cent ± 8 per cent.
    6. The temperature of the chamber (or room) in which the particulate filters are conditioned and weighed shall be maintained to within 295 K (22 °C) ± 3 K during all filter conditioning and weighing. The humidity shall be maintained to a dew point of 282,5 (9,5 °C) ± 3 K and a relative humidity of 45 ± 8 %.
    7. the emissions are sampled into a sampling bag over the cycle and measured after completion of the test; for HC, the sample bag shall be heated to 464 ± 11 K (191 ± 11 oC), for NOx, the sample bag temperature shall be above the dew point temperature;
