Determination of the particulates Sample Clauses

Determination of the particulates. The determination of the particulates requires a dilution system. Dilution may be accomplished by a partial flow dilution system or a full flow dilution system. The flow capacity of the dilution system shall be large enough to completely eliminate water condensation in the dilution and sampling systems, and maintain the temperature of the diluted exhaust gas between 315 K (42 °C) and 325 K (52 °C) immediately upstream of the filter holders. De-humidifying the dilution air before entering the dilution system is permitted, if the air humidity is high. Dilution air pre-heating above the temperature limit of 303 K (30 °C) is recommended, if the ambient temperature is below 293 K (20 °C). However, the diluted air temperature shall not exceed 325 K (52 °C) prior to the introduction of the exhaust in the dilution tunnel.

The particulate sampling probe shall be installed in close proximity to the gaseous emissions sampling probe, and the installation shall comply with the provisions of paragraph 2.3.5. To determine the mass of the particulates, a particulate sampling system, particulate sampling filters, microgram balance, and a temperature and humidity controlled weighing chamber, are required.

Determination of the particulates. Paragraphs 1.2.1. and 1.2.2. and figures 4 to 15 contain detailed descriptions of the recommended dilution and sampling systems. Since various configurations can produce equivalent results, exact conformance with these figures is not required. Additional components such as instruments, valve, solenoids, pumps and switches may be used to provide additional information and co-ordinate the functions of the component systems. Other components which are not needed to maintain the accuracy on some systems, may be excluded if their exclusion is based upon good engineering judgement.

The flow capacity of the dilution system shall be large enough to completely eliminate water condensation in the dilution and sampling systems, and maintain the temperature of the diluted exhaust gas at or below 325K (52°C) immediately upstream of the filter holders.

However, the diluted air temperature must not exceed 325K (52°C) prior to the introduction of the exhaust in the dilution tunnel. For a partial flow dilution system, the particulate sampling probe must be fitted close to and upstream of the gaseous probe as defined in paragraph 4.4. and in accordance with annex 4, appendix 4, paragraph 1.2.1.1., figures 4-12, EP and SP. 2.1.1.). To determine the mass of the particulates, a particulate sampling system, particulate sampling filters, a microgram balance and a temperature and humidity controlled weighing chamber are required. For particulate sampling, two methods may be applied: the individual modes of the test cycle. This method allows more lenient sample procedures but uses more filters.

Determination of the particulates. The determination of the particulates requires a dilution system capable of maintaining the temperature of the diluted exhaust gas at or below 325 K (52 °C) and preventing water condensation, a particulate sampling system, specified particulate sampling filters and a microgram balance which shall be placed in an air-conditioned weighing chamber. Dilution may be accomplished by a full-flow dilution or a partial-flow dilution system. Annex 4, appendix 4 describes the analytical systems in current use. Other systems which have proved to give equivalent results may be used. E/ECE/324 Rev.1/Add.48/Rev.3 Regulation No. 49 page 39 Annex 4 - Appendix 2
