Control Indicators for the Inspection Characteristic

Use

You use control indicators for the inspection characteristic, to influence the further processing of the inspection characteristic. With this control indicator, you define, for example, the characteristic type, specification limits, the type of results recording and whether the inspection characteristic must be inspected.

Integration

Depending on which control indicators you set for the inspection characteristic, you can influence the type of results recording, defects recording, whether a control chart is to be run, the sample size and the documentation for the inspection results. The link between master inspection characteristics and class characteristics enables the automatic transfer of inspection results to the batch classification , provided that you inspect with a material specification or task list. The class characteristics from the batch class are automatically valuated at inspection completion, on the basis of the inspection results.

Features

The following control indicators are available, depending on the characteristic type (quantitative or qualitative characteristic):

Characteristic Type	Indicator	What You Should Know
Quantitative	Upper specif. limit Lower specif. limit Check target value	You define, whether the target value lies within the tolerances and which limits are to be inspected. Depending on which indicators you have set, you can enter additional quantitative data and a tolerance key.
Quantitative	Confirm values	You define whether measured values are to be inspected and confirmed.
Quantitative	Calculated charac.	You define whether the inspection results are determined by the inspection of the inspection characteristic itself, or by other inspection characteristics within the same operation.
Quantitative/ qualitative	Sampling procedure	You define whether a sampling procedure must be assigned when the master inspection characteristic is used in the task list or in the material specification (optional for an inspection with a material specification).
Quantitative/ qualitative	SPC characteristic	You define whether a control chart is to be run.
Quantitative/ qualitative	Additive sample	When samples are calculated, you define whether the size of the partial sample is increased by the quantity that is required for the inspection of this characteristic.
Quantitative/ qualitative	Destructive insp.	You specify whether the sample is to be destroyed after inspection. This means that is no longer available. This quantity is used in the usage decision as the proposed quantity for the posting to sample.
Quantitative/ qualitative	Summ. recording Single result No charac. recording Classed recording Defects recording	You define the type of results recording for the master inspection characteristic.
Quantitative/ qualitative	Required charac. Optional charac. After accept. After rejection	You define whether the inspection characteristic must always be inspected, or whether it is only to be inspected under certain conditions.
Quantitative/ qualitative	Scope not fixed Fixed scope Smaller scope Larger scope	You define the inspection scope. For example, you specify whether the number of inspected units at results recording can be smaller or greater than the precalculated number of units to be inspected.
Quantitative/ qualitative	No documentation Docu. if rejected Docu. required	You define if and when additional text is to be entered, when you record results, for documentation purposes.
Quantitative/ qualitative	Long-term inspection	You define that the inspection is to take place over a long period of time. The usage decision can already have been made and the vendor can have been evaluated.
Quantitative/ qualitative	Scrap share/ q-score	You define whether the fraction of nonconforming units for this characteristic is taken into account, when the scrap share for the inspection lot is calculated (this only occurs if specific quality scores are used when the usage decision is made).
Quantitative/ qualitative	RR change docs	You define whether change documents are to be written for results recording based on characteristics.
Quantitative/ qualitative	Test-equi assignment	You define whether you can assign test equipment to the master inspection characteristic in the task list.
Quantitative/ qualitative	Print Do not print Do not print at skip	You define whether and under which conditions the master inspection characteristic is printed on the inspection instruction.
qualitative	Charac. attribute	You define whether you reference codes from a selected set in results recording, or whether you valuate manually with accepted or rejected. If you set this indicator, it affects the assignment of code groups and codes .
qualitative	Defects confirmation	You define whether defects are to be recorded if the characteristic is rejected.

Note Note

The following critical indicators (indicators that can lead to inconsistencies if a master inspection characteristic that is used in a task list or in a material specification is changed without history) cannot be changed: Sampling procedure, SPC characteristic, Test-equi assignment, Calculated charac., Charac. attribute, Lower specif. limit, Upper specif. limit .

If the master inspection characteristic is linked to a numeric class characteristic, you cannot change the following control indicators: Lower specif. limit, Upper specif. limit, Confirm values, Classed recording .

If the master inspection characteristic is linked to a numeric class characteristic with reference to a selected set, you cannot change the Charac. attribute control indicator.

If a master inspection characteristic is referenced in a material specification or included in a task list as a reference characteristic and you make a change without history, a change to the control indicators can lead to inconsistencies. You should therefore make a consistency check on the task lists and material specifications, in which this master inspection characteristic is included as a reference.
