28、 bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organiza

29、tions, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in th

30、e ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of t

31、he member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 13856-3 was prepared by Technical Committee ISO/TC 199, Safety of

32、machinery and by Technical Committee CEN/TC 114, Safety of machinery in collaboration.This second edition cancels and replaces the first edition (ISO 13856-3:2006), which has been technically revised.ISO 13856 consists of the following parts, under the general title Safety of machinery Pressure-sens

35、, and general aspects that can be applied to all machinery;b) Type-B standards (generic safety standards) dealing with one safety aspect or one type of safeguard that can be used across a wide range of machinery: type-B1 standards on particular safety aspects (e.g. safety distances, surface temperat

36、ure, noise); type-B2 standards on safeguards (e.g. two-hand controls, interlocking devices, pressure-sensitive devices, guards);c) Type-C standards (machine safety standards) dealing with detailed safety requirements for a particular machine or group of machines.This document is a type-B2 standard a

37、s stated in ISO 12100.The requirements of this document can be supplemented or modified by a type-C standard.For machines which are covered by the scope of a type-C standard and which have been designed and built according to the requirements of that standard, the requirements of that type-C standar

38、d take precedence.The safeguarding of machinery (see ISO 12100:2010, 3.21) can be achieved by many different means. These means include guards which prevent access to the hazard zone by means of a physical barrier (for example, interlocking guards according to ISO 14119 or fixed guards according to

39、ISO 14120) and protective devices (for example, electro-sensitive protective equipment according to IEC 61496-1 or pressure-sensitive protective devices according to this part of ISO 13856).Type-C standards makers and designers of machinery/installations should consider the best way to achieve the r

40、equired level of safety taking into account the intended application and the results of the risk assessment (see ISO 12100).The required solution can also be to combine several of these different means. The machinery/installation supplier and the user examine together carefully the existing hazards

41、and constraints before making their decision on the choice of safeguarding.Pressure-sensitive protective devices are used in a wide range of applications with different conditions of use relating, for example, to extremes of loading or electrical, physical and chemical environments. They are interfa

42、ced with machine controls to ensure that the machine reverts to a safe condition if the sensitive protective equipment is actuated.This part of ISO 13856 is restricted to the design of pressure-sensitive protective devices so that they can be used when the risk assessment carried out by the machine

43、manufacturer and/or relevant type-C standard, when available, shows this to be appropriate.This part of ISO 13856 does not specify the dimensions and the configuration of the effective sensing surface of the pressure-sensitive protective devices in relation to any particular application. However, th

44、ere is a requirement for the manufacturer of any safeguard to provide sufficient information to enable the user (i.e. the machinery manufacturer and/or user of the machinery) to specify an adequate arrangement.The forces for the activation of the pressure-sensitive protection devices specified in th

45、is part of ISO 13856 are based on the information available at the time of publication. These forces will be kept under review so that the results of further research into forces that can be applied to the human body without causing significant injury can be taken into account. While these forces pr

46、ovide a practical means for the design and testing of the pressure-sensitive device, they cannot prevent injury in all applications. When specifying the actuating force for a specific device or application many factors should be taken into account. These include the contact area, the contact speed,

47、the material used and the part of the body affected.

48、 ScopeThis part of ISO 13856 establishes general principles and specifies requirements for the design and testing of those pressure-sensitive protective devices, with or without an external reset facility, that are not specified in either ISO 13856-1 or ISO 13856-2, and the majority of which are pro

49、duced for specific applications and are not available as “off-the-shelf” items.This part of ISO 13856 also gives specific requirements for the following pressure-sensitive protective devices:a) pressure-sensitive bumpers;b) pressure-sensitive plates;c) pressure-sensitive wires (trip wires).It deals with the design of a pressure-sensitive device with regard to safety and reliability rather than its suitability for particular applications.NOTE 1 For the relationship between safety and reliability, see ISO 13849-1:2006, 4.2.NOTE 2 The machinery
