EN 23449:1988

EN 23449:1988 is a standard published by the European Committee for Standardization (CEN). Its full title is "Earth-moving machinery - Falling-object protective structures - Laboratory tests and performance requirements (ISO 3449:1984, ed. 3)". This standard covers: 1.1 This Internal Standard specifies a) the laboratory tests for measurement of structural characteristics, and b) the performance requiremets in a representative 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 protest 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 : 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.
