Option DVGW W 400-2 - 222600

DVGW Worksheet W 400-2 provides technical rules for water distribution systems, especially with regard to construction and testing. Established pressure test procedures, such as the contraction procedure or standard procedure, are specified in worksheet W 400-2. 

Our pressure test devices contain menu-guided test sequences for the proper execution of the procedures regulated in worksheet W 400-2:

• Contraction procedure
• Accelerated standard procedure
• Standard procedure
• Influence minimized Standard procedure

The smart memo guides you through the test in an automated process, displays measurement data and progressions, and stores and documents all relevant test data.

With the update of the worksheet (August 2022), stricter requirements will be placed on the measurement technology than before. In the course of further developments in the field of sensor technology and measurement technology, whereby significantly higher measurement value accuracy and stability are possible and common, this is a sensible adaptation of the regulations to the state of the art. You can find more information on the new requirements and changes due to the update of the regulations in our blog.
