What is BS EN 60068-2-17 - Sealing test methods about?
BS EN 60068-2-17 is a standard that covers sealing test methods, ensuring safety, sealing strength, and leakproof operations in industrial applications.
In BS EN 60068-2-17, Test Q: Sealing, includes several tests that use different conditioning procedures appropriate for different applications.
Test Q in BS EN 60068-2-17 may be subdivided into the following two sub-groups, distinguished by their detection methods, viz:
- Internal detection, which measures changes in electrical characteristics produced by the test medium (liquid or gas) introduced into the specimens through the leak
- External detection, whereby the escape of the test medium through the leak is observed
In BS EN 60068-2-17, Qk and Qm are used to determine leaks in containers (metallic cases, housings, etc.); Test Qc is a bubble test again including three methods with different sensitivities [leaks not less than 1 Pa·cm3/s (10–5 bar·cm3/s)]
In BS EN 60068-2-17, test method 1 is primarily applicable to specimens of small volume whose surfaces are not likely to impair the results by too high retention of adsorbed helium (such as braids, joints, organic materials, paint, etc.) unless they have been suitably neutralized before the detection phase.
In BS EN 60068-2-17, test method 2 is intended for specimens that have been filled, during manufacture or for the requirements of this test, with a mixture containing a large proportion of helium.
In BS EN 60068-2-17, test Method 3 (jet and pocket methods) is intended for specimens to be mounted on bulkheads or panels.
Note 1: BS EN 60068-2-17 method should be used judiciously, because it is possible to release into the room sufficient helium to swamp the spectrometer, resulting in the suspension of the test until the room has been ventilated.
Note 2: BS EN 60068-2-17 method should not be used where a numerical acceptance limit for leak rate is specified.
Who is BS EN 60068-2-17 - Sealing test methods for?
BS EN 60068-2-17 on sealing test methods applies to:
- Environmental testing agencies
- Simulation testing services
- Testing personnel and inspectors
- Quality assurance services
Why should you use BS EN 60068-2-17 - Sealing test methods?
Environmental testing is the process of determining product performance in specific environments. Sealing tests apply to various specimens and applications such as airtightness of bushes, container sealing gross leaks, container sealing fine leaks, and more.
BS EN 60068-2-17 provides users guidance on sealing tests for internal detection and external detection, enabling users to choose the appropriate method as per their use case.
BS EN 60068-2-17 provides users guidance on Test Qa: Sealing of bushes, spindles and gaskets, Test Qc: Container sealing, gas leakage, Test Qd: Container sealing, seepage of filling liquid, Test Qf: Immersion, Test Qk: Sealing tracer gas method with mass spectrometer and more.
BS EN 60068-2-17 also provides users with a step-by-step procedure for the test methods, enabling users to do the method correctly for acquiring accurate results.
With obedience and compliance to BS EN 60068-2-17, users can assess and implement different sealing test methods to ensure the prevention of leaks, sealing strength and prevention of hazards in industrial applications.
