BS ISO 10054:1998

This standard BS ISO 10054:1998 Internal combustion compression-ignition engines. Measurement apparatus for smoke from engines operating under steady-state conditions. Filter type smokemeter is classified in these ICS categories:

• 27.020 Internal combustion engines
• 13.040.50 Transport exhaust emissions

This International Standard specifies the characteristics required for apparatus to measure the soot content from the exhaust gas of reciprocating internal combustion compression-ignition (diesel) engines operating under steady-state conditions according to the method of blackening a filter. These measuring apparatus are called "Filter-Type Smokemeters".

This International Standard does not deal with apparatus for measurement under transient conditions; if filter-type smokemeters are used under transient conditions, the results of different types of instruments cannot be compared unless sampling conditions are identical.

This International Standard does not apply to engines for aircraft.
