Falling Weight Impact Tester is specially designed to determine the resistance to external blows of thermoplastic pipes and polymer test samples and components.
The apparatus conforms to the ISO3127, BS EN744 and EN 1411 test standards."Round the Clock Method" Lengths of pipe from a batch or production run are subjected to blows from a known mass which falls from a specified height.
Test standard ISO 3127 & 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.
Test standard EN1411.By changing the Supports and clamping mechanisms, along with the shape of the Tup, and variable weights tests to other standards such as ASTM D5628, D5420, D3029, D2444 can be carried out. |
- Specially designed to evaluate the
impact properties of polymer test
samples and components.
- Variable drop heights up to
2,000mm, giving a maximum
impact velocity of 6.264m/s.
- Variable drop weights between
1.25kg and 10kg.
- Maximum impact energy 196
Joules.
- Drop weight solenoid released
and automatically returned
using a pneumatically operated
rodless cylinder.
- The weight carrier can be
fitted with different tup designs.
- Picture shows version for testing
pipes and incorporating a
variable height “vee” rest for
pipes from 16mm to 400mm dia.
Also, fitted with anti-rebound
device to prevent the weight
striker hitting the pipe more
than once.

Impact Resistance by Falling Weight.
The impact energy is calculated from the drop height and drop weight, as follows :
Impact Energy = drop weight(kg) * drop height (m) * g
g= acceleration due to gravity = 9.81 m/s/s |
| Smaller & larger drop heights available, Larger bases to accept larger pipe diameters, Tup (Striker) shapes to customers requirements, Load carriers to customer's requirements, Optional weight sets available, Low Temperature Chambers, Tups to Customers specifications. |
