Introduction –  \nwhat are we informing you about?  \nWith this brochure, Endress+Hauser would like to explain the classification of certain characteristics in technical design drawings. The intention is to enable the test scope to be derived from the significance of the relevant markings.  \nNote:  \nTechnical design drawings also encompass technical supply conditions (TLBs) and circuit board layouts.  \nThe brochure is used across the whole of the Endress+Hauser SE+Co. KG company group.  \n2. Framework conditions  \n2.1 Fundamentals  \nCharacteristics are defined as all information used to technically describe a product, such as material, a product‘s properties, dimensions and so on.  \n2.2 Risk consideration  \nTo select the identification, the approval requirements and the empirical values are used as a basis. An analysis is performed of the significance of failure toadhere to a characteristic in terms of function, assembly capability, standards etc. The characteristic must then be identified as appropriate in the design drawing.  \n2.3 Identification categories  \nOverall, a distinction is made between three categories of identification:  \n• Critical characteristic  \n• Major characteristic  \n• Minor characteristic  \nThe individual meanings of the relevant categories are listed in the following.  \n2.4 Execution and significance of identification  \nCritical characteristic:  \nCharacteristics with this identification are dimensions or specifications whose failure would in all likelihood:  \n• Lead to hazardous or unsafe situations for persons using, repairing or depending on the affected unit.  \n• Lead to non-compliance with applicable standards or statutory requirements.  \n• Result in environmental damage.  \n• Lead to a system or plant failure.  \nIn the case of critical characteristics, a 100% inspection must be carried out to ensure adherence to requirements.  \nCritical characteristics are identified in design drawings as follows: In the above example these are circled in blue.  \nprevious identification  \nkritisches Merkmal /critical feature  \nMajor characteristic:  \nCharacteristics with this identification are dimensions or specifications in the design drawing which affect:  \n• Function  \n• Assembly capability  \nMajor characteristics must be included in the inspection instructions as characteristics to be tested.  \nMajor characteristics are identified in design drawings as follows: In the above example these are circled in green.  \nprevious identification  \nHauptmerkmal /main feature  \nMinor characteristics  \nMinor characteristics are not identified and are all other dimensions and specifications which are neither major nor critical characteristics.  \nprevious identification  \nEndress+Hauser Level+Pressure  \nEndress+Hauser SE+Co.
