ASTM F1306 Standard | Slow Speed Puncture Test Machine for Flexible Barrier Films & Multi-Layer Laminates | UnitedTest

UnitedTest manufactures ASTM F1306-compliant penetration resistance testers for food packaging, barrier film factories and material QC labs worldwide.

ASTM F1306 Standard Test Method for Slow Rate Penetration Resistance of Flexible Barrier Films and Laminates measures slow puncture performance of flexible plastic barrier films and composite laminates. The test runs under controlled constant low crosshead speed with biaxial stress applied to specimens, capturing three vital failure metrics: peak puncture force, rupture penetration displacement, and total puncture energy consumed to break the film sample.

Our dedicated ASTM F1306 penetration fixture matches standard clamping, probe speed and data recording rules, delivering repeatable puncture resistance data for packaging material formulation R&D and batch quality inspection.

ASTM F1306 evaluate the slow puncture/penetration resistance of flexible barrier plastic films, multi-layer composite laminates under biaxial stress at a constant low speed. It captures three core failure indicators: peak puncture force, penetration displacement at rupture, and total puncture energy consumed to break the film.

Test Principle

A square film specimen is rigidly clamped in a circular fixture to restrict sliding and generate uniform biaxial tension during penetration.

A standard hemispherical metal probe (3.2 mm diameter) descends vertically at a fixed slow crosshead speed to continuously squeeze and stretch the film.

The film undergoes elastic and plastic elongation first; when internal stress exceeds material limit, visible perforation (full penetration hole) forms, accompanied by an instantaneous sharp drop of load force to near zero on the force-displacement curve.

The test system records the full force-displacement curve throughout the whole process. Key parameters are extracted from the curve: maximum force (peak puncture resistance), probe travel distance from initial contact to rupture, and the integral area under the curve (total puncture work/energy).

For multi-layer laminates, multiple small force drops appear as individual layers break sequentially; the final load collapse to near zero is defined as complete material failure.

Tes Specimen Requirements

Specimen Dimension: 76 mm × 76 mm (3 in × 3 in) square sheet.

Multi-Layer Laminates Distinction: For asymmetric layered structures (e.g., ABC vs ABA), label inner and outer package sides separately, as penetration performance differs by loading direction.

Sample Quantity: Minimum 5 valid specimens per material/orientation for statistical averaging.

Required Test Equipment for ASTM F1306 Penetration Resistance test of plastic film

Universal Testing Apparatus (UTM)	A UnitedTest tensile/compression universal testing machine equipped with real-time data recording and acquisition function, capable of stable low-speed crosshead operation. The load range must be selected so specimen rupture force falls within 20%–80% of the full load scale to guarantee measurement precision.
Puncture test fixture	Standard Penetration Probe General-purpose probe: 3.18 mm (0.125 in) diameter hemispherical tip, spherical radius 1.6 mm, 6° taper shaft, overall length 13 mm, material hardness 50–56 Rc. This probe is required for interlaboratory comparative testing to ensure consistent biaxial stress state. If alternative probes are used, the fixture clamping diameter-to-probe diameter ratio must be ≥10:1.
Puncture test fixture	Specimen Clamping Fixture Circular ring fixture with a 35 mm internal test opening (fixed for cross-lab comparison). Pneumatic or mechanical clamping structure to fully lock specimens without slippage during stretching. Overall fixture dimension reference: 127 mm × 102 mm, dimensional tolerance ±0.51 mm.

Test Parameters

Crosshead descending speed: fixed at 25 mm/min (1.0 in/min).

Data acquisition resolution: minimum 0.1 mm data point interval for penetration displacement.

Chart recorder setting (if analog equipment used): chart speed 500 mm/min.

Probe linear tolerance: ±0.10 mm; angular tolerance doubled unless otherwise marked.

Fixture test aperture fixed at 35 mm for standard interlab correlation.

Standard Test Procedures of ASTM F1306 Penetration Resistance test

1, Equipment Calibration: Verify UTM and load cell are within valid calibration cycles; select matching load range.

2, Probe Installation & Centering: Mount the hemispherical probe, adjust position to align perfectly with the center of the fixture’s circular opening.

3, Sample Cutting & Thickness Measurement: Cut 76×76 mm specimens, measure three central thickness values per piece and record.

4, Specimen Clamping: Lay film flat in the fixture, fully tighten clamping mechanism to eliminate wrinkles and slippage; move crosshead down to a position just above the film without touching it.

5, System Reset: Reset force and displacement data collection channels to zero, set travel stop limits on the tester.

6, Initiate Test: Start crosshead downward movement. Terminate the test immediately once visible perforation occurs or load drops instantaneously to near zero, then retract crosshead to original position.

7, Data Recording: Log sample ID, peak break force (N), total break energy (J), penetration displacement at initial rupture (mm), and average film thickness.

8, Repeat Cycles: Complete testing on 5 replicate specimens for each material and surface orientation.

Calculation formula:

Peak Force: N = R × L = (D/W) × L

Probe Penetration Depth: P= (D × S)/C

Puncture Energy: J= I × L × (S/Z)

EN 14477 is an increasingly important testing standard due to the increasing popularity of lithium-ion batteries. Lithium-ion batteries include a separator material - the membrane between the battery’s anode and cathode - which has become increasingly thinner as manufacturers seek to improve conductivity and minimize the amount of space that it occupies. These separator films are commonly made from polymers and must be mechanically strong enough to withstand the winding operation during assembly of the battery. From a material evaluation standpoint, understanding the mechanical properties such as puncture resistance is important when determining which material is optimal.

ASTM F1306 Penetration Test of Flexible Barrier Films and Laminates

A single column tensile tester is a sophisticated material testing instrument designed for measuring mechanical properties of various materials under tension, compression, bending, shear, and other loading conditions. As the name suggests, it features a single vertical column supporting a moving crosshead that applies force to test specimens.

ASTM F1306 Penetration Resistance test of plastic film describes a method with very similar objectives for measurement of flexible barrier films and laminates. It uses an indenter with a tip radius of 1.6 mm and a conical shaft with a 6° angle.

Q1: What is the core purpose of ASTM F1306 test?

A1: It is a quasi-static puncture test standard to measure slow penetration resistance of flexible barrier films and laminates under biaxial stress. It quantifies three key failure indicators: peak puncture force, probe penetration distance at rupture, and total puncture energy, to evaluate how easily packaging films get pierced under slow, sustained compression from sharp contents.

Q2: Why is ASTM F1306 critical for flexible barrier packaging materials?

A2: Barrier failure risk control: Once perforated, films lose oxygen/moisture/odor barrier performance, shortening food shelf life or causing contamination of medical sterile products.

Simulate real logistics damage: Slow penetration mimics stacking pressure, long-term contact with sharp food edges, and static friction during storage—scenarios high-speed impact tests cannot replicate.

Multi-dimensional material evaluation: It delivers force (piercing hardness), displacement (ductility/stretchability), and energy (overall toughness) data, which differentiates brittle thin films from tough multi-layer laminates.

Standardized comparison: Unified probe, fixture, speed and conditioning rules eliminate lab-to-lab deviation for R&D formulation screening and incoming quality inspection.

Q3: What is the standard penetration probe specified in ASTM F1306 for general testing?

A3: A 3.18 mm (0.125 in) diameter hemispherical probe with 1.6 mm spherical radius, 50–56 Rc hardness. This design creates uniform biaxial stress and is mandatory for cross-laboratory data comparison. If custom probes are used, the fixture opening-to-probe diameter ratio must be at least 10:1.

Q4: What size specimen do I need to cut for the test? Any thickness requirements?

A4: Specimens must be 76 mm × 76 mm (3 in × 3 in) square sheets. Thickness uniformity must be within ±2% or ±0.0025 mm (whichever value is larger). Measure thickness at three central positions per specimen following ASTM F2251 and record the average.

Q5: What is the difference between repeatability limit (r) and reproducibility limit (R) in the standard precision section?

A5: Repeatability limit (r): The maximum allowable difference between two test results from the same operator, same machine, same day. Results differing more than r are considered non-equivalent (95% confidence).

Reproducibility limit (R): The maximum allowable difference between results generated in different labs, by different operators with different equipment. Larger R indicates higher cross-lab measurement variability.

Q6: What fixed crosshead speed is required for ASTM F1306 testing?

A6: The universal tester crosshead must run at 25 mm/min (1.0 in/min). This low slow speed is the core definition of “slow rate penetration” and cannot be arbitrarily changed for standard comparative testing.

Q7: How many replicate specimens are required for a valid test report?

A7: A minimum of 5 valid replicate specimens per material and surface orientation (inner/outer side of laminate). Do not arbitrarily discard samples with minor defects, as this will skew statistical results. Sampling strategy can refer to ASQ/ANSI Z1.9.

Q8: How to judge complete material failure (perforation) during testing, especially for multi-layer laminates?

A8: Perforation is defined as either a visible naked-eye hole in the film, or an instantaneous sharp drop of load to near zero on the force curve. For multi-layer laminates, multiple small force drops appear as separate layers crack; only the final load collapse to near zero counts as full specimen failure.

Q9: What similar puncture test standards can be confused with ASTM F1306, and what are the key differences?

A9: ASTM D5748: Stretch wrap protrusion puncture test — designed for pallet stretch films with different fixture geometry, not general barrier laminates.

ASTM F811: Dynamic puncture test — high-speed impact loading, opposite to F1306’s slow quasi-static penetration.

EN 14477 (EU static puncture): Uses sharp thin probes instead of F1306’s hemispherical tip, simulating different piercing scenarios.

Q10. Why does "slow-rate penetration" matter at all? Most people think of puncture as a drop/dart impact.

F1306 = slow, progressive pressure (25 mm/min). Simulates handling, stacking, product edges pressing into film over time, filling-line stress.

D1709 (free-falling dart) = high-speed impact. Simulates a box dropping.

Many real-world package failures are notdrops — they're a sharp product corner + weight + vibration slowly working through the laminate. F1306 catches the stretch-to-break behaviour (ductile vs brittle) that impact tests completely miss.

Q11: What if I use a penetration probe other than the standard 3.18 mm hemispherical tip?

A11: Cross-laboratory comparison data will no longer be comparable. If alternative probes are necessary for application-specific simulation, the fixture clamping diameter to probe diameter ratio must be at least 10:1, and all probe geometry details must be fully documented in the test report.

Q12: Why does the standard require a 35 mm circular test opening in the clamping fixture?

A12: This fixed aperture creates consistent biaxial tensile stress distribution across specimens during penetration, eliminating variable stress states caused by different opening sizes. It is a mandatory requirement to align with the historical round-robin precision data from six laboratories.
