Safety of machinery. Prevention of unexpected start-up1 Scope This document specifies requirements for designed in means aimed at preventing unexpected machine start up (see 3. 2) to allow safe human interventions in danger zones (see Annex A). This document applies to unexpected start up from all types of energy source, i. e.: power supply, e. g. electrical, hydraulic, pneumatic; stored energy due to, e. g. gravity, compressed springs; external influences, e. g. from wind. This document does not specify

mechanical characteristics and water impermeability

or types still in production

The solder is then exposed to prescribed conditions of humidity and the resulting corrosion
