Keeping Standards up-to-date Standards are living documents which reflect progress in science, technology and systems. To maintain their currency, all Standards are periodically reviewed, and new editions are published. Between editions, amendments may be issued. Standards may also be withdrawn. It is important that readers assure themselves they are using a current Standard, which should include any amendments which may have been published since the Standard was purchased. Detailed information about Standards can be found by visiting the Standards Australia web site at www.standards.com.au and looking up the relevant Standard in the on-line catalogue. Alternatively, the printed Catalogue provides information current at 1 January each year, and the monthly magazine, The Australian Standard, has a full listing of revisions and amendments published each month. We also welcome suggestions for improvement in our Standards, and especially encourage readers to notify us immediately of any apparent inaccuracies or ambiguities. Contact us via email at [email protected], or write to the Chief Executive, Standards Australia International Ltd, GPO Box 5420, Sydney, NSW 2001.

This Standard was issued in draft form for comment as DR 99041.

PREFACE This Standard was prepared by the Standards Australia Committee ME-020, Internal Combustion Engines, to supersede AS 1019—1985, Internal combustion enginesSpark emission control devices. The objective of this revision is to reconfirm the existing requirements and to present the Standard in the current editorial style.

When this Standard was originally being prepared, tests were carried out by the Agricultural Engineering Centre at Werribee which showed that turbochargers acted as spark arresters on compression-ignition engines; these results clarified the test methods which are reflected in the Standard. The terms ‘normative’ and ‘informative’ have been used in this Standard to define the application of the appendix to which they apply. A ‘normative’ appendix is an integral part of a Standard, whereas an ‘informative’ appendix is only for information and guidance.

This Standard specifies requirements for the materials, design, construction and performance of spark arresters for controlling the emission of sparks from internal combustion engines. A method of testing the performance of spark arresters is set out in Appendix A. This Standard does not cover the following: (a)

The risk of ignition of combustible materials by hot surfaces of the engine, the exhaust pipe, or the spark arrester.

(b)

Aspects of installation.

(c)

Applications in explosive atmospheres which may require flame arresting, exhaust gas cooling or isolation.

(d)

The effect of the spark arrester on engine noise levels.

NOTE: Recommended maintenance procedures are given in Appendix B.

2 REFERENCED DOCUMENTS The following Standards are referred to in this Standard: AS 1152

Specification for test sieves

1449

Wrought alloy steels—Stainless and heat-resisting steel plate, sheet and strip

3 DEFINITION For the purpose of this Standard, the following definition applies: 3.1 Spark arrester A device, system or method which controls the emission from an engine exhaust of particles potentially capable of igniting combustible material in the vicinity by virtue of their size and temperature. 4 RATING Spark arresters shall be rated according to— (a)

the type of engine to which the spark arrester is fitted (i.e. spark-ignition engine or compression-ignition engine); and

(b)

the highest net power output of the engine equipped with the standard production auxiliaries necessary for its operation for the particular application.

5 MATERIALS Materials used in the construction of spark arresters shall be suitable for the conditions of use (e.g. high temperature, acidic corrosion, weather). In particular, the following requirements apply: (a) Screens, where used, shall be made of stainless steel AS 1449/304L or AS 1449/316L or equivalent. © Standards Australia
