Cometech QC-636 Drop Weight Impact Tester | 100 J, 5 kg Striker, A/B Method, BS EN 1621-1 / EN 1621-2
- Drop weight impact tester for evaluating the impact-absorbing capacity of cushioning materials used in protective gear and packaging (sports armor, transport packaging).
- Standard 5 kg drop striker falls from 100 cm to deliver ~50 J; machine reads the energy absorbed by the specimen after impact.
- Supports both Impact Method A (EN 1621-1) and Method B (EN 1621-2); striker and anvil sets are interchangeable between A and B configurations.
- Electric weight lifting with electromagnet control and fail-safe mechanism — weight will not release during a power outage.

Overview
Cometech QC-636 Drop Weight Impact Tester is designed for cushioning and protective material testing using the free-fall drop weight method.
The 5 kg striker (including the impact head) is lifted electrically to a set height; at standard height of 100 cm it delivers approximately 50 J of impact energy vertically onto the specimen.
The machine then reads the residual energy after the specimen absorbs impact, which gives a direct measure of the material's cushioning performance.
It conforms to BS EN 1621-1:2012 (motorcycle protective armor — limbs) and BS EN 1621-2:2014 (motorcycle protective armor — back) standards.
Method A (EN 1621-1) vs Method B (EN 1621-2)
- Method A striker: Flat, polished face 40×80 mm; round edges r=5 mm. Anvil: Hemispherical polished steel, radius 50 mm, height 180 mm.
- Method B bar impactor: Hemispherical face 60°, radius 12.5 mm, height 30.8 mm. Anvil: Polished steel, radius 150 mm, height ~190 mm.
- Both impact method sets (striker + anvil) are included; they can be interchanged on the same machine frame.
Key Features
- Electric weight lifting — no manual raising required.
- Electromagnet weight control with power-outage fail-safe (weight cannot drop during power loss).
- Low-resistance linear guide tracks for smooth, consistent drop.
- Dedicated software included for test data display and analysis.
- Max. drop height 210 cm (adjustable).
Standards
- BS EN 1621-1:2012
- BS EN 1621-2:2014
