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.
Scope
1.1 This International Standard specifies
a) the laboratory tests for measurement of structural characteristics, and
b) 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.
