15、y of machinery Emergency stop Principles for design Scurit des machines Arrt durgence Principes de conception EN ISO 13850:2006 ii iii Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing I
16、nternational 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 organizations, governmental and non-governmental, in liaison
17、 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 the ISO/IEC Directives, Part 2. The main task of tech
18、nical 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 the member bodies casting a vote. Attention is draw
19、n 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 13850 was prepared by Technical Committee ISO/TC 199, Safety of machinery, and Technical Committee IEC/TC 44, Safe
20、ty of machinery Electrotechnical aspects. This second edition cancels and replaces the first edition (ISO 13850:1996), which has been technically revised. Notably, it incorporates the following significant changes: a) resetting of the emergency stop command is required to be manual (see 4.1.6); b) e
21、mergency stop devices are required to use mechanical latching (see 4.4.3). EN ISO 13850:2006 iv Introduction The structure of safety standards in the field of machinery is as follows. a) Type-A standards (basis standards) give basic concepts, principles for design, and general aspects that can be ap
22、plied to machinery. b) Type-B standards (generic safety standards) deal with one or more safety aspect(s) or one or more type(s) of safeguard that can be used across a wide range of machinery: type-B1 standards on particular safety aspects (e.g. safety distances, surface temperature, noise); type-B2
23、 standards on safeguards (e.g. two-hands controls, interlocking devices, pressure sensitive devices, guards). c) Type-C standards (machinery safety standards) deal with detailed safety requirements for a particular machine or group of machines. This International Standard is a type-B2 standard as st
24、ated in ISO 12100-1. When provisions of a type-C standard are different from those which are stated in type-A or type-B standards, the provisions of the type-C standard take precedence over the provisions of the other standards for machines that have been designed and built according to the provisio
25、ns of the type-C standard. EN ISO 13850:2006 1 Safety of machinery Emergency stop Principles for design 1 Scope This International Standard specifies functional requirements and design principles for the emergency stop function on machinery, independent of the type of energy used to control the func
26、tion. It is applicable to all machinery except for: machines in which the provision of emergency stop would not lessen the risk; hand-held portable machines and hand-guided machines. It does not deal with functions such as reversal or limitation of motion, deflection, shielding, braking or disconnec
27、ting, which can be part of the emergency stop function. 2 Normative references The following referenced documents are indispensable for the application of this document.

30、zards to persons, damage to machinery or to work in progress, be initiated by a single human action NOTE 1 Hazards, for the purposes of this International Standard, are those which can arise from functional irregularities (e.g. machinery malfunction, unacceptable properties of the material processed
31、, human error), normal operation. NOTE 2 Adapted from ISO 12100-1:2003, definition 3.37. EN ISO 13850:2006 2 3.2 emergency stop device manually actuated control device used to initiate an emergency stop function IEC 60947-5-5:2005, definition 3.2 3.3 machine actuator power mechanism used to effect m
32、otion of the machine IEC 60204-1:2005, definition 3.36 3.4 safety function function of a machine whose failure can result in an immediate increase of risk(s) ISO 121001:2003, definition 3.28 4 Safety requirements 4.1 General requirements 4.1.1 The emergency stop function shall be available and opera
33、tional at all times and override all other functions and operations in all operating modes of the machine without impairing any facilities designed to release trapped persons. It shall not be possible for any start command (intended, unintended or unexpected) to be effective on those operations stop
34、ped by the initiation of the emergency stop function until the emergency stop function is manually reset. When emergency stop devices can be disconnected (e.g. portable teaching pendants) or when machinery can be partially isolated, care should be taken to avoid confusion between active and inactive
35、 control devices. 4.1.2 The emergency stop function shall not be applied as a substitute for safeguarding measures and other safety functions but should be designed for use as a complementary protective measure. The emergency stop function shall not impair the effectiveness of protective devices or
36、of devices with other safety functions. NOTE For this purpose, it can be necessary to ensure the continuing operation of auxiliary equipment such as magnetic chucks or braking devices. 4.1.3 The emergency stop function shall be so designed that, after actuation of the emergency stop actuator, hazard
37、ous movements and operations of the machine are stopped in an appropriate manner, without creating additional hazards and without any further intervention by any person, according to the risk assessment. An “appropriate manner” can include choice of an optimal deceleration rate, selection of the sto
38、p category (see 4.1.4), and employment of a predetermined shutdown sequence. The emergency stop function shall be so designed that a decision to use the emergency stop device does not require the machine operator to consider the resultant effects. EN ISO 13850:2006 3 4.1.4 The emergency stop shall f
39、unction in accordance with either of the following stop categories. Stop category 0 Stopping by means of immediate removal of power to the machine actuator(s), or mechanical disconnection (declutching) between the hazardous elements and their machine actuator(s) and, if necessary, braking. Stop cate
40、gory 1 A controlled stop with power to the machine actuator(s) available to achieve the stop and then removal of power when the stop is achieved. Examples of the removal of power include switching off the electrical power to the electric motor(s) of the machine, declutching the movable elements of t
41、he machine from the source of mechanical energy, and blocking the fluid power supply to the hydraulic/pneumatic machine actuators of the machine. 4.1.5 The choice of either stop category 0 or 1, according to 4.1.4, shall be determined by the risk assessment of the machine (see also IEC 60204-1:2005,
42、 9.2.5.4.2). NOTE Requirements for safety-related functions can be found in ISO 13849-1 and IEC 62061, among others. 4.1.6 Once active operation of the emergency stop device has ceased following an emergency stop command, the effect of this command shall be sustained until it is manually reset. Rese
43、t shall be possible only at that location where the emergency stop command was initiated. The reset of the command shall not restart the machinery but only permit restarting. It shall not be possible to restart the machine until a manual reset of the emergency stop device has been performed at each
44、location at which the emergency stop was activated. 4.2 Electrical emergency stop equipment requirements Electrical equipment used for emergency stop shall be in accordance with the relevant requirements of IEC 60204-1. For the requirements relating to emergency stop devices, see 4.4 and IEC 60947-5
45、-5. 4.3 Operating conditions, environmental influences The components, devices and elements used to achieve the emergency stop function shall be selected, assembled, interconnected and protected such that they are able to operate correctly under the expected operating conditions and environmental in
46、fluences, including taking into consideration the frequency of operation and need for periodic testing, for example, in the case of infrequent operation, and the effects due to, for example, vibration, shock, temperature, dust, foreign bodies, moisture, corrosive materials and fluids. 4.4 Emergency
47、stop device 4.4.1 The emergency stop device shall be designed to be easily actuated by the operator and others who could need to actuate it. EN ISO 13850:2006 4 The types of actuators that may be used include the following: mushroom-type pushbuttons; wires, ropes, bars; handles; in specific applicat
48、ions, foot-pedals without a protective cover. 4.4.2 An emergency stop device shall be located at each operator control station, except where the risk assessment indicates that this is not necessary, as well as at other locations, as determined by the risk assessment. It shall be positioned such that
49、 it is readily accessible and capable of non-hazardous actuation by the operator and others who could need to actuate it. Measures against inadvertent actuation should not impair its accessibility. 4.4.3 The emergency stop device shall apply the principle of direct opening action with mechanical latching. Electrical emergency stop devices shall be in accordance with IEC 60947-5-5. NOTE An example of the application of th
