Define how a decision is made to accept or reject inspection
characteristics (valuation mode). These decisions are used in the
Integrate your own function modules that allow you to make the
decision whether to accept or reject inspection
You must decide which one of the basic forms you want to use.
These forms are as follows:
This is required for attributive characteristics (that is,
characteristics for which no values are recorded). These are
characteristics you simply accept or reject. This type of decision
is also used in all other cases, where an automatic valuation is
not possible or allowed.
Code valuation: a decision on the basis of qualitative
The decisions are stored in the catalog for characteristic
A decision based on a sampling plan for discrete
characteristics (attributive inspection) with the following
Number of defects
Number of nonconforming units
This also includes a decision based
on the tolerance specifications for the measured values of
A decision based on a sampling plan for quantitative
characteristics (variable inspection) with the following
Complying with the distribution limits of the characteristic
Complying with the mean value limits of characteristic values
(checking the tolerance specifications)
This is a special application of the s-method, where k = 0.
A decision based on a control chart.
You can assign suitable, different valuation rules to these
basic forms and thereby define different valuation modes, such
Code valuation. This valuation is based on the attributes of
Valuation based on the number of defects
Valuation based on the number of nonconforming units
The valuation of quantitative
characteristics according to whether they lie within the tolerances
of the measured results is also included under this heading.
Valuation based on tolerance specifications for the mean value.
This valuation uses the attributes of variable (quantitative)
characteristics by comparing the mean value with the limits of the
Valuation modes for procedures using sampling schemes:
Valuation according to sampling plan for:
Attribute inspection, for discrete characteristics (in
accordance with ISO 2859)
Variable inspection, for continuous characteristics (in
accordance with ISO 3951)
The system supports a single-sided
and double-sided s-method.
Valuation based on the limits of a control chart
Valuation modes for procedures using independent multiple
Valuation according to the:
Worst case principle
Last case principle
Best case principle
The valuation modes for procedures with independent multiple
samples are suitable for the valuation of characteristics in:
Inspections during production
Valuation based on inspection point results
Valuation of results for partial lots
Inspection of physical samples
Inspection of maintenance objects
In the standard system, the table of valuation rules is designed
so that all commonly used valuation modes are supported at
The tables have the
delivery class G. The following name range is reserved

other valuation modes are used in your company. If necessary, you
must also define and program appropriate valuation rules for these

b) Assign the valuation rules to the
relevant valuation modes.
The valuation mode is stored in the sampling procedure.
If you work with independent, multiple samples, enter an additional
valuation rule in the sampling procedure to link the characteristic
decisions for individual samples to an overall decision.
The valuation of an inspection characteristic is usually made up
of several steps that take place at the following levels:
Valuation of original values or value classes
In summarized results recording original values or value classes
are not valuated.
Valuation of samples
If the system does not allow for multiple samples, there is no
valuation at sample level
Valuation of a characteristic
The valuation rules mentioned above are active at characteristic
or sample level. At original value, or value class level, the
valuation rules that are dependent on the control key for the
characteristic are fixed automatically by the
Code valuation for qualitative characteristics with
Valuation based on tolerance specifications for quantitative
The valuation rule is stored in the valuation mode and can be
included in this way in the sampling procedure.
There are two valuation rules for independent multiple samples; one
for characteristic-based decisions for individual samples and one
for characteristic-based decisions for all samples.
Inspections during production can cover several inspection
points and partial lots; valuation rules are also required for
You may also require additional valuation rules, for example for
characteristic valuation in an inspection of physical samples or
