| # Standard Test Procedure Characteristics (qmptc0115m000) Use this session to define the quality requirements for characteristics. The characteristics defined for a quality ID apply to all the quality combinations to which the quality ID is assigned. In the details session, you link multiple characteristics or aspect/characteristics combinations to a quality ID. You can add properties for a quality ID like test, norm, limits method, and effective date. Note The default data of characteristics can be changed. Related topics Standard test procedure and testing combinations Standard Test Procedure The code to which data is linked that is necessary to check the quality requirements of an item. Since one standard test procedure can be used for a group of products that require the same quality standards and tests, a standard test procedure can considerably reduce time. Aspect An aspect is a specification of a feature. Characteristic A reference to a particular quality or distinctive mark of an item or an item part/component. For example, diameter, length, weight. Description The description or name of the code. Origin Order Sequence This is a sequence number that allows you to define the same characteristic multiple times, but each time with a different expiry date. Characteristic Type The following types of characteristics are available: Possible Values. Method The following methods are available: Possible Values. Characteristic Unit The unit in which an item's characteristic is expressed, for example, meters, kilograms. Characteristic for Algorithm If this check box is selected, this characteristic can be used as a variable or as a constant in the algoritm of another characteristic. Test The test that is used by default for measuring the characteristic. Fixed Characteristic Value A characteristic value that is determined once. The fixed characteristic value is compared to the test results entered in the following session: Inspection Order Test Data (qmptc1115m000) Note This field only applies if the Method field is set to Fixed. If the Characteristic Type field is set to Integer, the Fixed Characteristic Value field is rounded off to the nearest integer.
Example
User entry | Rounded value
5 | 11
4 | 10
6 | 11
Algorithm An expression that is used to compute a characteristic by means of other variables or fixed characteristics. Note You can use the Algorithm field, only if you entered Algorithm in the Method field. Option Set A group of possible values of a characteristic. For each value (option) you can indicate whether it is acceptable or not. The options blue and red form an option set Example
Characteristic | pH value
Test | Litmus test
Options | blue = acceptable
red = not acceptable
Note You can enter an option set if the Characteristic Type field is on Option. Effective Date The date on which you can perform a test to inspect items. Expiry Date The date on which you can no longer perform a test to inspect the characteristic for this quality ID. Characteristic Standard The standard normally used for characteristics. For example, a DIN standard Limit Type The type of value that is measured. Allowed values Possible Values Value Type The value type of the characteristic. Allowed values Value Type Chart Name The code of the chart name to which the nominal values are applicable. Note This field is available only if the Nominal option is selected in the Value Type field. Chart Type The code of the chart type for which the nominal values are applicable. Note This field is available only if the Nominal option is selected in the Value Type field. Tolerance Standard The code of the tolerance standard linked to the nominal value range. Note This field is available only if the Nominal option is selected in the Value Type field. Nominal Value The nominal value of the characteristic, expressed in the characteristic unit. Note This field is available only if the Nominal option is selected in the Value Type field. Norm The norm is the desired quality for this characteristic, expressed in the characteristic unit. Note This field does not apply if you enter Fixed in the Method field or Option in the Characteristic Type field. Upper Limit Type in the highest characteristic value, expressed in the characteristic unit, for which the quality is acceptable. Note The Upper Limit field must be greater than or equal to the value in the Norm field. Lower Limit Type in the lowest characteristic value, expressed in the characteristic unit, for which the quality is acceptable. Note The Lower Limit field must be greater than or equal to the value in the Norm field. Upper Tolerance Type in the maximum percentage that a value can be higher than the norm in the Norm field. Lower Tolerance Type in the percentage that a value can be lower than the norm in the Norm field. |
