This publication constitutes the refereed lawsuits of the ninth overseas convention on complex info platforms Engineering, CAiSE'97, held in Barcelona, Spain, in June 1997. the amount offers 30 revised complete papers chosen from a complete of 112 submissions; additionally integrated is one invited contribution.
Praxis und Wissenschaft sind sich einig, dass die elektronische Beschaffung indirekter G? ter (Nicht-Produktionsmaterial) wenig Wettbewerbsvorteile schafft. Die weitaus gr? ?eren Herausforderungen und Einsparpotenziale liegen in der Beschaffung direkter G? ter (G? ter, die in die Leistungen eingehen).

Teacher control panels should only be active through a hold-to-run switch and should include an emergency stop button. (b) From the potential energy of counterbalance weights should the supporting chain or cable break. d). (c) Air receivers rupturing if operating pressures exceed safe working pressures. (d) Air hoses where misdirected air jets can penetrate the skin and from the whipping movement of an unrestrained end of a flexible hose. (e) Steam boilers and pipework where the escaping steam has a high potential heat capable of causing serious burns.
It was superseded by BS ISO 14121:1999 which is being completely revised. BS EN ISO 12100 parts 1 & 2: 2003 covers various aims of design that need to be considered and the techniques available for achieving those aims. BS EN ISO 13849 is concerned with ensuring an adequate level of safety through setting performance levels (PL) and specifying categories of equipment. It contains a risk graph for determining the needed performance levels and also tabulates the relationship between PLs and SILs.
For simplicity, the safeguards shown are based on the ‘unit’ approach of guarding each hazard separately. e. areas of potential hazard coloured red and safe conditions with guards in place are coloured green. 1 Rotary movement (a) Plain shaft No matter how smooth the shaft, when it is rotating it will ‘pick up’ loose clothing and materials which will become entangled around it. An explanation of this phenomenon is given in Appendix 4. Where there is no suitable place to attach a fixed guard, plain shafts can be protected by means of a loose sleeve fitted over the exposed part of the shaft with a minimum of 12 mm (12 in) clearance.
