AS 2294.3-1997

Specifies the means for evaluating the characteristics of falling object protective structures (FOPS) under static loading and prescribes performance requirements for a representative sample under such loading. It is to be read in conjuction with AS 2294.1 and AS 2294.4. This Standard is identical with and has been reproduced from ISO 3449:1992.

1.1 This International Standard specifiesa) the laboratory tests for measurement of structural characteristics, andb) the performance requirements in a representive test,of a falling-object protective structure (FOPS).1.2 The laboratory tests are a means of testing the characteristics of the structures used to protect the operator from localized impact penetration and, indirectly, of the load-carrying capacity of the supporting structure to resist impact loading.1.3 This International Standard establishes a consistent, repeatable means of evaluating characteristics of FOPS under loading and prescribes performance requirements for these structures under such loading in a representative test.NOTE 1 For the purposes of this International Standard, "representative test" means a test of a specimen whose material, dimensional, and processing requirements are typical of those FOPS currently being produced.1.4 This International Standard applies to the following types of operator-controlled machines, regardless of the type of steering system used, as defined in ISO 6165:- crawler loaders, wheel loaders and backhoe loaders:- crawler tractors and wheel tractors;- graders;- tractor-scrapers.1.5 This International Standard does not apply to- self-propelled compactors;- drills;- paving machines;- machines having a power rating less than 15 kW (20 hp);- belt loaders;- excavators;- cranes;- drag lines.
