Type Approval documentation

Tests carried out

Each gauge and temperature calibrator has been calibrated at factory and is delivered with a valid calibration certificate. 2907, 2908 and GaugeCalXP pressure sources have been pressure- and leakage tested of up to 100% of design pressure. 150% pressure test (or higher) has been performed for all gauge designs.

Marking of product

Each model is marked with manufacturer name, model name and serial number.

Certificate retention survey

The scope of the retention/renewal survey is to verify that the conditions stipulated for the type are complied with, and that no alterations are made to the product design or choice of systems, software versions, components and/or materials.

The main elements of the survey are:

· Ensure that type approved documentation is available

· Inspection of factory samples, selected at random from the production line (where practicable)

· Review of production and inspection routines, including test records from product sample tests and control routines

· Ensuring that systems, software versions, components and/or materials used comply with type approved documents and/or referenced system, software, component and material specifications

· Review of possible changes in design of systems, software versions, components, materials and/or performance, and make sure that such changes do not affect the type approval given

· Ensuring traceability between manufacturer's product type marking and the type approval certificate

Retention survey is to be performed at least every second year and at renewal of this certificate.
