Test Dimensions¶

Test Dimensions indicate that the orderer requires the manufacturer to verify that the dimensions of the produced part adhere to the specifications. Sometimes the orderer even requires a test of all produced parts (i.e., a 100% test).

With WERK24 you can check your drawings for theses features and even automatically create First Article Inspection Reports.

Criticality¶

Sometimes the orderer defines that criticality of the Test Dimensions (e.g., Critical to Function or Critical to Price). WERK24 gives you access to this information. See W24TestCriticality for details.

Label¶

While not required, some orderer define a label for the specific Test Dimension, so that the First Article Inspection Reports that they receive from their suppliers all follow the same scheme. This information is available through the label attribute

Rate¶

When the orderer defines a test rate for the part, this information is available through the rate attribute. Common test ratios are 50% and 100%.

Models¶

Test Dimensions can be accessed by requesting the Measures: W24AskVariantMeasures

Requesting the Test Dimensions¶

from werk24 import Hook, W24AskVariantMeasures, W24Measure

    )
