30、E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards 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

31、technical committee has been established has the right to be represented on that committee. International organizations, 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 matter

32、s of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the 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

33、 to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the 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 fo

34、r identifying any or all such patent rights.ISO 13856-1 was prepared by Technical Committee ISO/TC 199, Safety of machinery and by Technical Committee CEN/TC 114, Safety of machinery in collaboration.This second edition cancels and replaces the first edition (ISO 13856-1:2001) which has been technic

35、ally revised.ISO 13856 consists of the following parts, under the general title Safety of machinery Pressure-sensitive protective devices: Part 1: General principles for design and testing of pressure-sensitive mats and pressure-sensitive floors Part 2: General principles for design and testing of p

36、ressure-sensitive edges and pressure-sensitive bars Part 3: General principles for design and testing of pressure-sensitive bumpers, plates, wires and similar devices ISO 2013 All rights reserved vBS EN ISO 13856-1:2013ISO 13856-1:2013(E)IntroductionThe structure of safety standards in the field of

37、machinery is as follows:a) Type-A standards (basic safety standards) giving basic concepts, principles for design, 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

38、 wide range of machinery: Type-B1 standards on particular safety aspects (e.g. safety distances, surface temperature, 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

39、 detailed safety requirements for a particular machine or group of machines.This document is a type-B2 standard as 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 hav

40、e been designed and built according to the requirements of that standard, the requirements of that type-C standard 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 m

41、eans of a physical barrier (for example, interlocking guards according to ISO 14119 or fixed guards according to 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 1385

42、6).Type-C standards makers and designers of machinery/installations consider the best way to achieve the required 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 differen

43、t means: the machinery/installation supplier and the user examine together carefully the existing hazards 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 relatin

44、g, for example, to extremes of loading or electrical, physical and chemical environments. They are interfaced with machine controls to ensure that the machine reverts to a safe condition if the sensitive protective equipment is actuated.ISO 13856 is restricted to the design of pressure-sensitive pro

45、tective devices so that they can be used when the risk assessment carried out by the machine manufacturer and/or relevant type-C standard, when available, shows this to be appropriate.vi ISO 2013 All rights reservedBS EN ISO 13856-1:2013Safety of machinery Pressure-sensitive protective devices Part

46、1: General principles for design and testing of pressure-sensitive mats and pressure-sensitive floors1 ScopeThis part of ISO 13856 establishes general principles and specifies requirements for the design and testing of pressure-sensitive mats and pressure-sensitive floors normally actuated by the fe

47、et for use as devices for protecting persons from hazardous machinery. The minimum safety requirements for the performance, marking and documentation are given.This part of ISO 13856 is applicable to pressure-sensitive mats and pressure-sensitive floors, regardless of the type of energy used (e.g. e

48、lectrical, hydraulic, pneumatic or mechanical), designed to detect persons weighing more than 35 kg, and persons (e.g. children) weighing more than 20 kg.It is not applicable to the detection of persons weighing less than 20 kg.It does not specify the following because they are application-specific:

49、a) dimensions or configuration of the effective sensing area of pressure-sensitive mat(s) or pressure-sensitive floor(s) in relation to any particular application;b) when pressure-sensitive mats or floors are appropriate in a particular situation;c) performance levels (PLs) for safety-related parts of control systems (SRP/CSs) other than providing a minimum level.This part of ISO 13856 gives guidance to assist the user (i.e. machinery manufacturer and/or user of the machinery) in providing an adequate arra
