Benefits
- Supplied as standard with a solenoid-operated carrier release mechanism for simple operation.
- Unique pneumatic carrier return system to ensure the carrier is safely returned to its set drop height for the next test to be performed.
- Twin guide rail system is used to ensure a smooth repetitive drop of the load carrier perpendicular to the sample being tested.
- Full electrical interlock system enhances user safety by preventing operation of the apparatus if a safety guard is open.
- Load carriers are available for different energy ranges and fitted with low friction bearing guides, which prevent velocity and potential energy being lost as the carrier descends.
- Impact tups are supplied to international test standard methods or to customers’ individual requirements, which can include simulation of failure modes seen in actual service conditions, or analysis for in-house quality control standards.
- On the standard machine, pipe diameters up to 400mm can be easily tested.
- Complies to various international standards, such as ISO 6603, ISO 3127, ASTM D2444, etc.
- 110 or 240 volt available.
- Operating pressure 100 PSI (7 bar).
- Product user manual.
- CE declaration certificate.
- Traceable calibration certificate.
- One year return to base warranty.
- Fixtures for conducting Izod and Charpy tests are also available.
- For specific component testing, bespoke clamping fixtures can be designed and manufactured to your individual testing requirements and parameters.
How to conduct a test
Prepared samples are placed in the enclosed chamber on their supporting fixture, which can be adjusted vertically to accommodate different test sample sizes. If the optional pneumatic clamping fixtures are used, the integrated safety system of the apparatus ensures the clamp doesn’t operate until the cabinet door is in the closed position.
Testing methods on the Universal Falling Weight Impact Tester (Drop Test Machine)
Round the Clock Method – Lengths of pipe from a batch or production run are subjected to blows from a known mass that falls from a specified height as per test standards ISO3127 & EN744.
Staircase Method – Lengths of pipe are subjected to blows from a known mass and shape but is dropped from differing heights depending on the results of each blow as per test standard EN1411.
Fixtures – By changing the supports and clamping mechanisms, along with the shape of the Tup, and variable weights the Ray-Ran Universal Falling Weight Impact Tester can be manufactured to meet any test specification or customer’s requirement making the equipment truly bespoke. Typical test fixtures available include
Pipe Testing “V” rest – The test is used for the examination of pipe sections and tubing for impact strength properties as complete segments of pipe. Sample diameters from as little as 12mm Ø up to 400mm Ø can be tested on the standard machine. The pipe is supported in a 120° angled “V” support as is impacted by the load carrier in a single drop. The support rests can be manufactured to any test standard or customer requirement.
Flat Plate / Plaque Testing – Testing of flat plates or plaques such as laminates and composites can easily be tested using the flat plate clamping fixture. It’s offered with various support rings to test to various international test standards and customers’ own specific testing requirements; and can be either manually or pneumatically operated.
