AS 3584.4:2021 pdf free download – Diesel engine systems for underground coal mines Part 4: Emissions.
This document specifies the test equipment, test cycles, performance and reporting requirements for
type testing of exhaust emissions for diesel engine systems (DES) to be used in underground coal mines.
This document applics to—
(a) (ire-protected DES as defined In AS 3584.1; and
(b) explosion-protected DES as delined in AS 3584.2.

(c) For EsDES, with minimum oF 0.6% CH4 induced into the air intake—
(i) at NRSC Test Mode 1; and
(II) at NRSC Test Mode 5 (varIable speed engines only).
2.4.6 Measurement of pollutants
For each mode, the concentrations of the following pollutants shall be measured before and alter all treatment:
(a) Carbon Dioxide (CO2)
(la) Carbon Monoxide (CO).
(c) Nitric Oxide (NO).
(d) Nitrogen Dioxide (NO2).
(e) Hydrocarbons (total HC or non-methane HCs as a propane equivalent).
(1) Oxygen (Ox).
(g) Ammonia (NH3) (where SCR type NO5 reduction systems are used).
At the tailpipe, with and without ‘T’pe 2 (removable) filter devices, if used—
(I) elemental carbon (EC):
NOTE 1 Determined by the NIOSH 5040 method for analysis of total carbon (TC) elemental carbon (EC) and organic carbon (OC),
(ii) diesel particulate matter (PM); and
(iii) particle size distribution.
NOTE 2 An instrument having a size range capability from 5 nm to 1 000 nm may be appropriate For this measurement.
NOTE 3 A graphical representation otthe mobility diameter of particles should he provided.
NOTE 4 Where equipment Is available, particle number may be measured in place of the particle size
distribution and reported by suitable graphical representations.
2.4.7 Specific emissions
The specific emissions for each gaseous emission shall be obtained from the test cycle to Clatises 2.4.1.
2.4.2 or 2A3. using the weighting factors in the relevant Table 1 or Table2. with the values of NO and NO2 combined to give total NO and as follows in Equations 3 to 5.
