• Reference conditions for concentrations are set at a pressure of 101.3 kPa and a standardised temperature of 25 °C.
• The document specifies reference methods for various pollutants: ISO 7996 for nitrogen dioxide, EN 12341 for the matter fraction of suspended particulate matter, the UV photometric method as described in SANS 13964 for ozone, and ISO 4224 for Carbon Monoxide.
