Purpose

This component allows you to include devices in sample lots. Lots can be created for devices subject to certification from the electricity, gas, water and district heating divisions. Sample lots are divided into external and internal lots. This allows you to inspect devices on the basis of legal requirements or internal quality standards.

A fixed number of sample devices is drawn from each lot. If the sample devices pass inspection, the entire lot will be renewed.

Due to the individual responsibilities of the different instances worldwide (calibration authorities, for example), a general certification of this sampling procedure is not possible. You should therefore check the permissibility of this procedure before you implement it.

Different requirements for the described procedures (in particular with regard to the drawing of samples) are not provided for as standard. You can however use the interface described below for this purpose. These interfaces provide support for enhancing or modifying the standard procedure.

Implementation Considerations

This component is optional. You require it if you wish to create sample lots.

Integration

If a lot fails, normally all devices are placed in the periodic replacement list (unless a device has already been removed) and certified individually. To do this, you need the Periodic Replacement (IS-U-DM-IS-PR) and Certification (ISU-DM-IS-CT) components.

The scope of the inspections is determined by the Inspection Point Group (IS-U-DM-TD-IG) component of the relevant device category. You can then enter inspection results using the Inspection Results Management (IS-U-DM-IS-IS) component. Neither component is required for the sampling procedure, however.
