EN 12978:2003+A1:2009 (E) 5 Introduction This European product related Standard has been prepared to meet the needs of manufacturers, users and safety enforcement authorities, with the primary purpose of providing design and performance requirements for various types of sensitive protective equipment employing different methods of sensing, for installation on power operated doors used by vehicular and pedestrian traffic. This document is a type C-standard as stated in EN 1070. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this document. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard. Sensitive protective equipment (safety devices) for manufacturing machinery are specified in EN 1760-1, EN 1760–2, EN 61496-1 and IEC 61496-2, which are ”Type B2” standards as specified in EN 292-1. Sensitive protective equipment (safety devices) for power operated doors are not used in the same circumstances as safety devices for manufacturing machinery such as: a) be suitable for use by, and to give protection to, untrained persons, and in particular applications may be used to protect elderly persons, disabled persons and children; b) be suitable for use outdoors, possibly in severe climatic and environmental conditions; c) be capable if required, to form an integrated part of the door construction and/or perform additional functions, e.g. providing a means of sealing the door; d) incorporate appropriate features for power operated door applications. Some safety devices for manufacturing machinery have e.g. a re-start interlock feature which, if used on power operated doors, could cause the door to operate incorrectly and could lead to heat losses, without increasing the level of safety. Some provisions of this standard are different from the provisions specified in EN 1760-1, EN 1760-2, EN 61496-1 and IEC 61496-2. Where sensitive protective equipment (safety devices) are designed and built for use on power operated doors, the provisions of this standard take precedence. This standard can not ensure that all possible hazardous situations will be eliminated. A particular attention should be given to the risk analysis when small children and /or elderly persons have to be detected. With the aim of clarifying the intention of the standard and avoiding doubt when reading it, following assumptions were made when producing it: components are kept in good repair or working order; negotiation occurred between the manufacturer and the user concerning the specificity of the use and place of use of the safety device. SIST EN 12978:2003+A1:2009
EN 12978:2003+A1:2009 (E) 6 1 Scope 1.1 General This European Standard applies for design, construction and testing of sensitive protective devices where the device is used to detect pedestrians including in particular applications, slow moving elderly persons, slow moving disabled persons and children who may be exposed to injury by power operated doors, gates and barriers, electrically powered from a public supply and intended for installation in areas in the reach of persons, and for which the main intended uses are giving safe access for goods and vehicles accompanied or driven by persons in industrial, commercial, public or residential premises. This standard also covers safety devices for commercial doors such as rolling shutters and rolling grilles when used as doors on retail premises which are mainly provided for the access of persons rather than vehicles or goods. !Noise is generally not a relevant hazard for this type of machinery." This standard deals with all significant hazards listed in annex A and specifies requirements to eliminate or minimise them. This standard covers the requirements for electrical powered safety devices using mains supply provided for installation on or used in conjunction with powered doors in order to avoid hazardous situations which can be encountered when a door is used normally. The sensitive protective device is designed to give a change in the output signal switching device which may be used to provide protection for the person being at risk. It applies to ready to use sensitive protective device and integrated sensitive protective device (mounted on or connected to a power operated door in normal use). This standard only applies to door safety devices manufactured after the date of publication. 1.2 Exclusions This European Standard does not apply to protective equipment for installation on doors which are intended for a different use than the one described above such as: lock gates and dock gates; doors on lifts; doors on vehicles; doors mainly for the retention of animals; theatre textile curtains; railway barriers; barriers used solely for vehicles. This standard does not apply to devices used only for the normal control and stopping, including emergency stopping, of power operated doors. This standard does not apply to safety equipment or safety devices for use on machinery other than doors. This standard does not cover operation in environments where the electromagnetic disturbances are outside the range of those specified in EN 61000-6-4 or for domestic domestic garage doors those of EN 55014-2. This standard does not cover products to be used in potential explosive atmosphere or on armoured doors. SIST EN 12978:2003+A1:2009
EN 12978:2003+A1:2009 (E) 7 This standard does not cover programmable devices (see IEC 61508 series). This standard does not deal with shock resistance of component (example IK code). The above exclusions are based on technology used at the publication time of this standard. 1.3 Door types and applications Doors, and gates can be sliding, sidefolding, tilting, pivoting, rolling, vertical lifting, etc. with many variances for each type. If not specified otherwise, the word ”door” refers to any of these types and variances of doors, and gates. This standard does not specify configuration of the sensitive protective device in relation to the door to be protected. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.
