Other Testing Capabilities

Water Pressure Test

APT Laboratory has the capability of water pressure testing hydro-mechanical components in a variety of configurations to 15,000 PSI.

Distilled water is often used to proof pressure test assemblies to avoid expensive cleaning processes after testing.

Chamber is 2 feet by 2 feet by 1.5 feet deep.

Pneumatic Pressure Test

The test sample is fitted with the appropriate test adapter and is installed onto a flexible hose. The line is purged of air using Nitrogen gas. The test sample is then submerged in water and pressurized with Nitrogen gas until the specified test pressure is achieved. This pressure is maintained for a specified period of time and is monitored for leakage as indicated by bubbles escaping from the test sample.

Salt Spray Testing:

Salt Spray testing is performed to the test parameters of ASTM-B-117. Testing is available for exposure times varying from a few hours up to thousands of hours. Salt Spray testing is generally used in conjunction with other tests such as flexure and / or impulse. Specific test parameters may require salt spray exposure before, at intervals during or after other mechanical testing

Stress Corrosion Testing:

Stress Corrosion Testing is conducted using a constant load deflection test fixture. Typically specimens are loaded to various levels of applied stress using a mechanical fixture and measured using a strain gage. It is common to test several specimens at various stress levels.

The effects of corrosion on stressed specimens are introduced using salt spray cabinets. The amount of stress, time exposed to corrosion and the concentration of salt is determined by the test parameters.

Mechanical Induced Stress

 

Mechanical Strength Testing:

Joint strength testing is conducted in accordance with AS18280 and similar procurement specifications. Axial load testing of test specimens and assemblies in either tension or compression can be performed including fabrication of specialized test fixtures.

Tube twisting, torque testing, repeated assembly and disassembly testing.

Test Specimen Cross Sectioning & Mounting:

A number of different sectioning techniques are available to support failure analysis, weld evaluation, microhardness testing and mechanical testing. Precision sectioning can be performed on small parts or for parts requiring examination of small areas of interest.

Microscopic Examination & Documentation:

Cross sections can be cut from areas of interest in the sample being evaluated and the physical configuration can be examined at various magnifications. Any findings can be documented using digital photography.

Test Program Management:

In addition to our inhouse capabilities we have close working relationships with several other accredited local laboratories where we can outsource testing. Our expert staff manages and monitors such outsourcing with detailed instructions and on site observations of the tests being run. All data is closely evaluated and reported. Some of the types of tests we have outsourced are:
