QE-DWI300 300 J Falling-Weight Impact Tester
The QE-DWI300 is a controlled drop-hammer impact testing system for evaluating the resistance of thermoplastic pipes, fittings, rigid plastic sheets, and related products to external impact. It combines programmable drop-height positioning, interchangeable impact tups, automatic hammer lifting, and first-impact capture for repeatable laboratory and quality-control testing.

Frequently Asked Questions
What materials can the QE-DWI300 test?
It is primarily configured for thermoplastic pipes, fittings, conduit, rigid plastic sheets, boards, and similar finished products.
What is the maximum available impact energy?
The maximum specified impact energy is 300 J.
Can it test large-diameter pipe?
The standard configuration supports pipes up to 400 mm diameter. An extended configuration for pipes up to 630 mm is available.
How is secondary impact prevented?
A hammer-capture mechanism restrains the falling mass after the first strike, reducing the risk of rebound causing an unintended second impact.
Can the machine test both pipes and sheets?
Yes. Pipes use compatible impact tups and a V-type support. Sheet testing requires the appropriate radiused tup and support fixture.
