SAFETY OF MACHINERY - TWO-HAND CONTROL DEVICES - FUNCTIONAL ASPECTS AND DESIGN PRINCIPLES (ISO 13851:2002, IDT)
This Malaysian Standard specifies the safety requirements of a two-hand control device and the dependency of the output signal from the input signals. This Malaysian Standard describes the main characteristics of two-hand control devices for the achievement of safety and sets out combinations of functional characteristics for three types. It does not apply to devices intended to be used as enabling devices, as hold-to-run devices or as special control devices.
