3 Foreword This standard has been prepared by DIN Working Committee NA AA Zeitbezogene Begriffe für Verpackungsmaschinen of Section Nahrungsmittelmaschinen of the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee). This standard serves to promote mutual understanding between manufacturers and users of packaging machines and packaging lines with respect to the selection and calculation of key figures (also referred to as indicators ) for the description of the operating behaviour of these machine systems. For this purpose it differentiates between general and technical key figures and formulates requirements for the collection of technical key figures in acceptance tests. The system of key figures developed in DIN 8743: has been fully re-worked for this purpose. The standard can also be applied analogously to other technically related processing machines. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. DIN [and/or DKE] shall not be held responsible for identifying any or all such patent rights. Amendments This standard differs from DIN 8743: as follows: a) the title of the standard has been modified; b) the time model has been revised and expanded; c) a differentiation is no longer made between packaging machines and packaging lines. Instead, uniform reference is made to machine systems which are defined by their system boundaries. As a result, no structures for packaging machines or lines are defined and no differentiation is made between key figures for packaging machines and packaging lines; d) references to important factors influencing the collection of technical key figures have been added, and minimum requirements for the performance of acceptance tests for the collection of key figures have been formulated; e) a differentiation has been made between technical key figures and general key figures. Previous editions DIN 8743: ,

4 Introduction The operation of packaging machines and packaging lines is subject to numerous influences on the part of the machines and linking devices themselves, the upstream and downstream systems, the contents of the packaging, the packaging, the auxiliary packaging, the production organization, the service and maintenance personnel and the ambient conditions at the installation site. As a result, the packaging process is not disruption-free. During the operation of the packaging machine or packaging line, periods in which production takes place according to plan and to the required standard of quality stochastically interchange with periods in which disruptions lead to losses (e.g. due to scrap or production stoppages). This operating behaviour of a packaging machine or packaging line can be characterized by key figures, established from partial times on the basis of the structure of the machine working time and the output produced, or producible, during these periods. This standard defines a time model and an output model derived from this time model. These can be used to define general key figures and technical key figures for describing the operating behaviour of packaging machines and packaging lines. For this purpose, the technical key figures only take into consideration lost time and output losses that can be attributed to each packaging machine or packaging line examined. Technical key figures are often based on agreed characteristics that are checked as part of an acceptance test. In practice, the system boundaries forming the basis of the acceptance test and that of the organizational and technical boundary conditions clearly influence the value determined for each key figure. This standard specifies requirements for the proper performance of an acceptance test, the modalities of which should be agreed by the participating parties prior to the acceptance test being carried out. 4

5 1 Scope This standard is applicable for packaging machines falling within the scope of DIN EN 415-1, referred to in the following as machine systems. This standard can also be applied by analogy to other related processing machines. This standard does not contain safety requirements. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. DIN EN 415-1, Packing machines safety Part 1: Terminology and classification of packing machines and associated equipment 3 Terms, definitions and symbols 3.1 Terms and definitions For the purposes of this standard the following terms and definitions apply machine system system machines and lines with defined system boundaries regarding introduction of processing materials (contents of the packaging and/or packaging/auxiliary packaging), operating materials, the release of output s, waste or scrap processing material referring to packaging machines: contents of the packaging, packaging, auxiliary packaging or package output processing material after passing through the machine system A packaging process consists of sub-processes in accordance with the basic tasks of packaging (i.e. forming, filling, sealing, wrapping) as well as the sub-tasks such as the cleaning of the packaging or labelling. In the context of this standard, the packaging process comprises the respective machine system with the defined system boundaries. An output can be an intermediate product of the packaging process, a package or a loading acceptance recognition of fulfilment of agreed characteristics of the machine system acceptance test test production to determine selected characteristics of the machine system acceptance period agreed duration of an acceptance test disruption unplanned event that compromises or interrupts the production of quality output s 5

Note 3 to entry: This time category includes calculated loss times due to a reduced working speed as compared with the set performance as well as scheduled and unscheduled times without performance that are not attributable to disruptions (e.g. due to start-up or emptying times or supply of processing materials (contents of packaging, packaging or auxiliary packaging)) quality time t Q time period in which the machine system produces in a manner conforming to the required standard of quality Mathematical variable loss time t L sum of unplanned down time, scrap time and performance loss time Mathematical variable loss time caused by machine system t LS sum of loss times that can be attributed to the machine system 7

Organizational causes include e.g. a shortage of product or packaging, unavailability of service or maintenance personnel, performance losses due to packaging or product qualities that do not comply with specifications, power failures, shortages of supply media output sum of all output s in a defined time period quality output q Q output of output s conforming to quality produced in the operating time scheduled output q O scheduled quality output Planning variable agreed output q OA agreed output of output s conforming to quality in a defined time period manufactured output q M actual output of produced output s including scrap output losses q L difference between scheduled output and quality output 8 Mathematical variable output losses caused by machine system q LS output losses that can be attributed to the machine system output losses not caused by machine system q LE output losses that cannot be attributed to the machine system

The key figures given here are appropriate for describing the operating behaviour of the machine system during the operating time when used as intended. The key figures are established on the basis of time and output losses that have been determined empirically or in simulations. This standard differentiates between general key figures and technical key figures. General key figures describe the operating behaviour without having to distinguish, when establishing loss outputs or loss times, whether their causes lie in the machine system itself or outside of the considered machine system, i.e. external to the machine system. In contrast to this, output losses and loss times caused external to the machine system are not taken into consideration for technical key figures. Thus, to establish technical key figures it is necessary that when determining output losses and loss times their causes are also clarified. In practice this involves additional effort as, for instance, displayed disruptions of the machine system can be caused by technical disruptions of upstream or downstream machine systems, by operating errors or by the flawed quality of the processing materials. 4.2 Calculation bases For the calculation of the general key figures and the technical key figures the rules for calculation presented in 3.2 as well as the time model given in Annex A and the output model given in Annex B shall be used. 15

16 4.3 General key figures for describing the operating behaviour To describe the operating behaviour of machine systems at least the following general key figures shall be determined: Quality performance p Q Efficiency E, where E = Q P The determination of further general key figures shall be agreed separately, if necessary. NOTE 1 These key figures refer to the operating time. They take into consideration disruptions of the machine system as well as performance and quality losses. Here, no distinction is made as to whether disruptions in the machine system or performance or quality losses have been caused by the machine system itself or the causes lie outside of the considered machine system. NOTE 2 Disruptions that result in the machine system no longer being able to go into production during operating time are not taken into consideration. These are included in key figure A (availability) and OEE. 4.4 Technical key figures for describing the operating behaviour To describe the operating behaviour of machine systems at least the following technical key figures shall be determined: technical quality performance p QS ; technical efficiency E S ; technical availability R S. The determination of additional technical key figures shall be agreed separately, if necessary. NOTE These key figures refer to the operating time. They take into consideration disruptions to the machine system as well as performance and quality losses provided their causes do not lie outside of the considered machine system. Disruptions that result in the machine system no longer being able to go into production during operating time are not taken into consideration. 5 System acceptance For the system acceptance the key figures given in 4.4 shall be determined in an acceptance test in accordance with Annex C. Lack of agreement regarding individual points requiring mutual agreement in accordance with Annex C is itself not a reason for a deferral of the acceptance test, nor is it a reason to call into question the validity of the acceptance test. As a deviation from the above, acceptance of systems without constant set performance that are product output controlled, or otherwise externally controlled, may be performed as follows, with all points requiring to be fulfilled: 16 1) Determination of technical quality performance at specified nominal performance (short-term test run under specified conditions), and 2) Acceptance test subject to the requirements described in Annex C only for determining the technical availability, also taking into account scrap time caused by the machine system. NOTE Individual machines are frequently integrated in entire complexes. For this purpose, the set performance of the machine is often governed by the upstream or downstream machine systems. In an acceptance test under practice-related conditions, the system does not allow the set performance to be maintained constant for these types of integrated machine systems. For this reason it is not generally possible to determine the efficiency of such machine systems in accordance with this standard.

Number and tasks of service personnel The number and tasks of the qualified operators required for the acceptance test shall be agreed upon. It shall be agreed whether personnel of the user, of the supplier or external personnel will be employed. Qualified personnel shall be provided by the user, unless otherwise agreed.
