Seminar for special machine builders I – Conception, realisation and design of leak and flow test stations

In some industries, it has long been standard practice to carry out a 100% end-of-line test as part of quality control to ensure leak-tightness or flow. The products and requirements encountered in practice are correspondingly diverse. The properties of the product must also be taken into account when designing the adaptation.This online seminar provides valuable tips and recommendations as well as an overview of the selection criteria for testing technology, taking project planning data into account.

Table of contents

• Basics of leak and flow testing
• Industrial leak testing methods
• Test methods with compressed air: pressure decay measurement, differential pressure method, laminar flow measurement
• Selection criteria for testing technology and components
• Practical tips on material selection and test station design
• Influence factors and interference in practice
• Project planning data, system design and industrial interfaces
• Adaptation of different test part types (e.g. products with pressure compensation elements, encapsulated or flexible test parts)
• Product-specific sealing concepts
• Stability of the test process

Target group

Special machine builders who are involved in the integration of leak or flow test stations – from beginners to experienced users who want to extend their knowledge.

The CETA range of test devices includes leak and flow testers with pressure sensors as well as mass flow testers for quality assurance. The CETATEST 625 mass flow tester works with the calorimetric (thermal) measuring principle and enables precise determination of mass flow rates – from the smallest leakage rates to larger flow rates. One advantage is the output of the measured values according to standardised reference conditions. This enables a reliable and comparable evaluation of the test results.

The CETA mass flow tester series is presented in this online seminar. In addition to the functional principle, practical examples and possible applications are also explained.

Table of contents

• Mass flow tester CETATEST 625
• Measuring principle of calorimetric mass flow measurement
• Measuring ranges and operating mode
  Indirect mode and post-flow method for low mass flow rates
  Direct pressurisation via pressure regulator 
• Measuring unit Nml/min and reference condition
• Use of test leaks and master jets for calibration checks
• Applications in industrial leak testing

Target group:

This online seminar is aimed at planners and machine builders who are interested in the CETA mass flow tester series, the measuring principles and practical applications.

Leak testing in the production line – Practical approaches for determining the test parameters test pressure and leakage rate

Many products are exposed to a variety of influences during operation. In some cases, this also requires tightness against dirt and moisture. These requirements are described in the definition of IP protection classes, for example.

The IP protection class tests are type tests. In these tests, prototypes are tested in the laboratory for tightness against the ingress of particles. The result is summarised in a test certificate which, strictly speaking, is only valid for the sample tested.

The routine test serves as proof of consistent product and manufacturing quality. In the production of large quantities and in some sectors, it is common for products to be 100% tested for tightness against moisture during production.

The leak test integrated into the production process cannot be carried out under the conditions of laboratory testing. Appropriate specifications (test pressure and leakage rate) must be defined here. The test parameters and the test method are often defined in the specifications. However, this is not always the case, so suitable parameters must be defined that are appropriate to the operating conditions of the product and its area of application. Important aspects of routine testing during production and practical approaches to defining the test parameters are presented.

Table of contents

• Type tests and routine tests
• IP protection class and production practice
• Industrial leak test methods
• Approaches for selecting the test pressure
• Approaches for selecting the leakage rate
• Limitations and practical comments

Target group

This online seminar is aimed at product developers, industrial engineers and quality managers who are interested in methods for determining the test parameters (test pressure and leakage rate) for the industrial leak test process. This seminar is also important for those, who define the specification or evaluate the test parameters for suitability.
