In terms of fluid technology there is no closed regulatory system in terms of safety technological requirements. Rather, these are distributed over a series of rules, regulations and standards of the institutions for statutory accident insurance and prevention, with some of them handled in great detail and some tackled very generally.
The most important rules and regulations of the institutions for statutory accident insurance and prevention include:
- ZH 1/457 and ZH 1/52 and ZH 1/74;
- VBG 7n5.2 Hydraulic presses,
- VBG 8 Winches, Lifting and Hoisting Devices,
- VBG 16 Compressors,
- VBG 40 excavators, loaders, etc.
There are also DIN standards and guidelines:
- DIN 24 295 Pumps and pumping sets,
- DIN 24 346 Hydraulic systems,
- DIN 31 000 General safety guidelines,
- VDI guidelines 3229 Technical design of machine tools, pneumatic equipment,
* VDI guidelines 3230 Technical design of machine tools, hydraulic equipment.
Separate regulations apply for the particularly dangerous accumulators:
- DIN 24 552 Hydraulic accumulators in hydraulic systems,
- AD data sheet A2 Safety equipment to prevent overpressure; safety valves,
- Accumulator ordinance dated 27.2.1980.
- Technical rules for accumulators, in particular TR 3/404.
The increasing role of electronics in controls of hydraulic systems is forcing system designers to also consider the safety regulations for electrical engineering, as defined in the German Accident Prevention Regulations UVV VGB 1 and 7 for general mechanical engineering. VDE 0113 and VDE 0160 also apply.
