Leak and flow testing in the production process

CETA exhibits at the Fakuma and MEDICA trade fairs

CETA Testsysteme GmbH is solution partner and manufacturer of test equipment in the field

of industrial leak and flow testing for more than 35 years. The test devices are used in the

manufacturing process during routine testing. As a rule, every product is tested (100 % end-

of-line testing).

Within the scope of a comprehensive project clarification, all data relevant for the testing

process are determined. This serves to ensure technical feasibility. For this purpose,

preliminary tests with original test parts of the customer are sometimes necessary. This

ensures that the test device offered fully meets the customer's requirements. And with the

CETA User Experience Package, customers are given the opportunity to conduct their own

tests. This approach has proven itself many times over and has contributed to a high level of

customer satisfaction. Several thousand CETA test devices are now in use worldwide by

well-known industrial customers.

The demand for product-specific leak and flow tests is increasing, especially in the medical

technology and plastics industries. The driving forces are product guidelines, stricter

requirements for documenting product quality, and the reduction of risks through inline testing

integrated into the production process.

Many plastic products (e.g. containers, pipes, closures, flap valves) must be tight against the

ingress or leakage of media. To ensure this, they are leak tested during the manufacturing

process in the production cycle. The range of product volumes to be tested varies from 0.1

ml to 1,000 l. Among the products for which the flow is tested are membranes, filters and

pipes. With CETA flow testers, a range from 3 ml/min to 220 l/min can be covered by different

laminar flow elements.

Medical devices must function reliably under a wide variety of conditions. Media-carrying

products (e.g. pipettes, syringes, catheters, filter elements, tube connectors, insulin pumps,

valves) must be tight against liquid leakage, while other products require tightness against

liquid or moisture ingress (such as cameras, endoscopes, sensors, actuators, displays,

control elements, packaging). And the correct flow must be ensured reliably and precisely

(e.g. for cannulas, membranes, filter elements, pipettes, valves).

With the test devices of CETA Testsysteme GmbH leak rates down to 10 -6 mbar*l/s and flow

rates up to 220 l/min can be detected. Compressed air, nitrogen or hydrogen (forming gas: 5

% hydrogen, 95 % nitrogen) are used as test media. A variety of available industrial

interfaces support the customer in documenting the test results.

CETA Testsysteme will present practical solutions at the following trade fairs in Q4 2023:

Solutions for leak testing of plastic products will be presented at the international plastics

trade fair Fakuma (Oct. 17-21, 2023, Friedrichshafen, Germany). A practical demonstration

will show the leak testing of an encapsulated plastic product. And at the world's largest

medical trade fair, MEDICA (Nov. 13-16, 2023, Düsseldorf, Germany), the focus will be on

leak and flow testing of medical devices. At the CETA booth, the leak test of a medical device

with a table jig will be demonstrated in a hands-on manner. In addition, a lecture on "Leak

and Flow Testing of Medical Devices in the Manufacturing Process" will be held on

14.11.2023, integrated into the stage program of the community stand of the state of North

Rhine Westfalia.
