AThe reference measuring instrument for the measurement of piezoelectric and dielectric small-signal data such as frequencies, impedances, coupling factors, capacitances and loss factors, is the Precision Impedance Analyzer 4194A from Agilent Technologies (formerly HP).
DC measurements with voltages of up to 1200V are carried out in an automated test routine on actuators to determine the strain, hysteresis and dielectric strength. AC measurements in the high-power acoustic range are used to determine acoustic performance.
Geometric and visual testing processes
In general, calibrated measuring equipment of appropiate precision is used
to verify the geometry of the components.
Ceramic components must be conform to visual specifications and
Unless specified otherwise, it is held that visual peculiarities do not
necessarily affect the functioning of the component.
Quality monitoring, quality level
PI Ceramic works with quality management systems and is certified in
accordance with ISO 9001-2000.
We carry out all tests of the electrical, mechanical and visual properties
in accordance with standardized sampling methods. The level of testing is in
accordance with DIN ISO 2859 Part 1.
If the customer so requires, it can also be agreed that this includes providing copies of the respective release documents, metrology reports or, in special cases, individual test reports on samples or entire batches.
