Safety Standard of Machinery, Equipment and Tools Article 15

Mechanical parts, electrical parts, wires, switches or other parts for the safety device of the press or shear machine shall meet the following provisions:1. The body, the linkage material, the lever and other major mechanical parts have sufficient strength.2. Linking parts:(1) Their materials comply with the national standard CNS 3828 “mechanical-structure-usage carbon-steel material” S45C or others having equivalent or more mechanical properties.(2) The surface of linking parts is treated by quenching and tempering, and their hardness must be above 45 to 50 in Rockwell C scale.3. Wire cables:(1) They comply with the national standard CNS 10000 “machinery-control-usage cable” or others having equivalent or more mechanical properties.(2) They are tightly fixed on the slider, levers and others with clips, clamps and so forth.4. Preventing loosing shall be applied to bolts, nuts and others on the safety device that may lead the device being malfunction or fitting parts falling off. Preventing falling off shall be applied to pins on the hinge portion too.5. Relays, limit switches or other major electrical parts shall have sufficient strength and durability to ensure safety device performances.6. The safety device with electrical circuits shall have indicators to display its actuated states, relay malfunction or failure of other circuits.7. Mounting portions for relays, transistors, capacitors, resistors or other electrical parts have vibration-proof performance.8. Circuits in safety device have the performance to prevent the slider accidental action when relays, limit switches or others are failure or power-failure.9. Operating voltage for the electrical circuit shall be less than 160 volts.10. External wires shall meet the national standard CNS 6556 “600V PVC insulated and coated light weight cables” or have equivalent or more insulation, oil-resistance, strength and durability.11. Switches:(1) For a button-switching type of the safety device, it shall have a construction to let buttons selecting switching positions respectively.(2) It can exactly keep holding at each switching position.(3) It is clearly to mark the state of the safety device related to each switch position.
