Puncture Fixture Equipment - Features and Applications

Puncture fixtures are used to evaluate the puncture resistance of materials such as plastic films, fabrics, and geomembranes. ADMET offers customized puncture fixtures, or customers can select fixtures designed according to specific testing methods.

Testing Standards

ASTM D751 Section 18 & Section 22

Fixture Configurations

ASTM D751 includes two distinct sections dedicated to evaluating the integrity of coated fabrics through burst and puncture testing. Section 18 specifies the use of a spherical plunger for determining the bursting strength, whereas Section 22 employs a sharper puncture probe to measure the puncture resistance.

Both assessments are performed in a compressive mode, with the plunger or probe descending towards the specimen, securely positioned within the FS-PT-ASTM D751 specimen holding ring. This holding ring is consistently used for both testing methods as prescribed by ASTM D751.

Testing Standard

ASTM D3787

Fixture Configurations

FS-PT-ASTM D3787 uses a constant-rate-of-traverse (CRT) ball burst test to determine the bursting strength of textiles. It includes a specimen holding ring measuring 44.45 mm (1.75 in) in diameter and a probe with a radius of 12.7 mm (0.5 in). Textiles or fabrics with a high degree of ultimate elongation can be tested using this method. 20 kN and 50 kN fixture options are also available.

Testing Standard

ASTM F1306

Fixture Configurations

The ASTM F1306 standard outlines a test method for measuring the slow rate penetration resistance of flexible barrier films and laminates. ADMET provides the FS-PT-ASTM F1306-SV, designed to test samples up to 35 mm (1.375 inches) in diameter, using a probe with a radius of 1.6mm, as stipulated by the standard. Additionally, for single-column universal testing machines with throat lengths shorter than 203 mm (8 inches), ADMET offers a single-column version of the FS-PT-ASTM F1306 fixtures.
