7、 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 technical committee has been established has the right to be represented on that
8、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 matters of electrotechnical standardization. The procedures used to develop this docume
9、nt and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives
10、, Part 2 (see www.iso.org/directives). 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. Details of any patent rights identified during the development

Figure 1 Basic PE system structure 3.10 product equivalent original equipment manufacturer or third party certified product that is a direct replacement in design, make, model, and version (
29、built to the same production drawings) of the original certified product 4 Instruction manual content This clause addresses special considerations for process and additional content of instruction manuals applied to PE system as described in ISO 22201-1 and ISO 22201-2. 4.1 Safety precautions In cre
30、ating an instruction manual, the developer should carry out a risk assessment to identify and address possible hazards for this phase of the life cycle of PE system. (See ISO 14798 for possible hazard assessment methodology). 4.2 Markings, signs, pictograms and written warnings Assemblies containing
31、 SIL rated devices should be labelled or tagged with identification information, in accordance with national requirements, and indicate that the maintainer should refer to the ISO 2016 All rights reserved 3 ISO/TR 22201-3:2016(E) instruction manual for detail instructions and precautions. Where poss
32、ible, readily understandable signs and pictograms taken from applicable ISO standards should be used, for example, ISO 7000:2014, symbol 1640. If the risk assessment indicates that additional specific warnings are required for the purpose of maintenance, these will be affixed directly on the install
33、ation/component or, when this is not possible, in the close vicinity. Markings, signs, pictograms and written warnings should be readily understandable and unambiguous. Signs or written warnings carrying only “DANGER” should not be used. Information affixed directly on the installation/component sho
34、uld be permanent and legible. 4.3 Elements to consider for content of the instruction manual Listed below are elements to consider for contents of the instruction manual. See also A.1 for additional elements of consideration. a) All the necessary operations to ensure the safe and intended functionin
35、g of the installation and its components after the completion of the installation and throughout its life cycle. b) Repair or changing of components which may occur due to wear or tear and does not affect the characteristics of the installation. c) Modernization of the installation, including the ch
36、anging of any characteristic of the installation (speed, load, etc.). d) Rescue operations carried out by fire brigades and emergency personnel. e) The specifications and the intended use of the installation (type of installation, performance, type of goods to be transported, type of users, etc.). f
37、) The environment in which the installation and its components are installed (weather conditions, vandalism, etc.). g) Any restriction of use. h) The result of the risk assessment (see 4.1) for every working area and for every task to be undertaken. i) The specific maintenance instructions provided
38、by the manufacturer of the safety elements. 5 Procedure The instructions for maintenance of PE system are provided by the manufacturer when placed on the market. They should be the result of a risk assessment and written in the official language(s) of the country for the location of the installation
39、. When preparing the content of the maintenance instructions, the following elements should be taken into account in the manual. a) Control documents Control documents are identified and maintained for the life of a PE system that includes SIL rated hardware or software. These documents include: 1)
40、Functional requirements: i) design specifications (system and element/subsystem); ii) production specification;4 ISO 2016 All rights reserved ISO/TR 22201-3:2016(E) iii) version identification and version control. b) Maintenance activity and record keeping of maintenance activity The following maint
41、enance activities, date and explanation of reason for the activity of PE system are recorded and retained by the owner for the life of the PE system installation: 1) preventative maintenance of the safety device (scheduled safety function actuation, proof test, etc.); 2) failure event of the safety
42、device; 3) modification in the PE system device (obsolescence, upgrade, reliability improvement, etc.); 4) modification of the interfaces to the safety device or its environment. c) Validation of replacement or modification process Replacements or modifications that result from the maintenance activ
43、ities in (b) should be made according to the process outlined in A.2 and should not modify the minimum required SIL for the function. Where SIL relevant and non- SIL relevant functions (those indicated in ISO 22201-1 and ISO 22201-2 are in circuits driven by or communicating with SIL rated parts) ar
44、e included in the design of the SIL rating of the PE system, changes made to software or hardware of the non-SIL relevant functions are treated in the same manner as a change to the SIL relevant portion of the PE system.
