ASTM D6241, ISO 12236 PUNCTURE JIG Static Puncture Testing of Geotextiles and related products
ASTM D 6241(ISO 12236):“This test method is an index test used to measure the force required to puncture a geotextile and geotextile-related products.
The relatively large
size of the plunger provides a multidirectional force on the geotextile.” TEST METHOD:“A test specimen is clamped without tension between circular plates and secured in a tensile or compression testing machine, or both. A force is exerted against the center of the unsupported portion of the test specimen by a steel plunger attached to the load indicator until rupture occurs. The maximum force is the value of the puncture strength.”
APPARATUS: TESTING MACHINE- Fits the requirement of specification D 76.
PLUNGER? Flat diameter of 50mm ±1mm with 2.5 radial edge ±0.5mm
Clamping Apparatus? Consisting of concentric plates
with an internal diameter of 150mm and external diameter of 250mm. Capable of clamping the test
specimen without slippage (limit slippage of test specimen to 5mm)
SALT CO., LTD.’s Geotextile puncture jig fit to ASTM D 6241 standard was created using pneumatic method.
By using this method on the jig, test
preparation time was greatly reduced and is capable of clamping the test sample
with a great amount of force.
