AS 2788:2002 pdf free.Pneumatic fluid power—General requirements for systems.
4 Requirements
4.1 General
The requirements stated in 4.1.1 to 4.5 apply to all systems within the scope of this
International Standard.
4.1.1 Instructions
Pneumatic systems shall be installed and used in accordance with the instructions and
recommendations of the system supplier.
4.1.2 Language*
The supplier and purchaser shall agree on the language to be used for machine marking and applicable documentation. The supplier shall be responsible for ensuring that any translation has the same meaning as the original text.
4.2 Hazards*
When agreed between purchaser and supplier, an assessment of the hazards listed in annex B shall be performed. This assessment may include the influence of the pneumatic fluid power system with other parts of the machine, system or environment. Standards listed in annex B may be used in this assessment.
So far as is practicable, the hazards identified shall be eliminated by design and, where this is not practicable, the design shall incorporate safeguards against such hazards.
4.3 Safety requirements
4.3.1 Design considerations
When designing pneumatic systems, all intended operations and use of the systems shall be considered.
Pneumatic systems shall be designed and components selected, applied, mounted and adjusted to provide uninterrupted operation, extended life and safe operation.
In the event of a failure, safety of personnel shall be the prime consideration, and damage to equipment and the environment minimized. Possible modes of failure and intended operations and use shall be considered.
4.3.2 Component selection
All components in the system shall be selected or specified to provide for safety in use, and they shall operate within their rated limits when the system is put to its intended use. Components shall be selected or specified to operate reliably under all intended uses of the system. Particular attention shall be paid to the failure mode of components that could cause a hazard in the event of their failure or malfunction.
4.3.3 Unintended pressures
All parts of the system shall be designed or otherwise protected against pressures exceeding the maximum working pressure of a system or any part of the system or the rated pressure of any specific component.
Systems shall be designed, constructed and adjusted to minimise surge pressures and intensified pressures. Surge pressures and intensified pressure shall not cause hazards.
Attention should also be paid to the consequences of blockages, pressure drops or leaks which could affect safe operation of components.
4.3.4 Mechanical movements
Mechanical movements, whether intended or unintended (including effects from, for example acceleration, deceleration or lifting/holding of masses), shall not result in a situation which is hazardous to persons.AS 2788 pdf download.
