It should, however, be noted that the Gesetz ber Einheiten im

10、 Messwesen (German Law on units in metrology) prohibits the use of the unit “pphm” for official and commercial purposes in Germany. Conversion: At standard conditions of atmospheric pressure and temperature (101 kPa, 273 K), a concentration of 1 pphm is equivalent to a partial pressure of ozonized a

11、ir of 1,01 mPa. Amendments This standard differs from DIN EN ISO 14113:2009-01 as follows: a) in Subclause 7.5, the temperature value has been corrected; b) the standard has been editorially revised.
