8、 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
9、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 te
10、sts. The system of key figures developed in DIN 8743:2004-06 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 o
11、f 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 8743:2004-06 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
12、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 mach
13、ines 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 techni
14、cal key figures and general key figures. Previous editions DIN 8743: 1987-01, 2004-06 DIN 8743:2014-01 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 syst
15、ems, 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
16、 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
17、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 d
18、efine 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 lin
19、e 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 determi
20、ned 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. DIN 8743:2014-01 5 1 Scope This standard is applicable for packaging m
21、achines 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 p
