ASTM E345 is a set of standard test methods for tension testing of metallic foils. This standard provides information on material strength and ductility under uniaxial tensile stress. This information may be useful for material comparisons, alloy development, quality control, and design.
ASTM E345 Standard Test Methods for Tension Testing of Metallic Foil
What is ASTM E345?
What is the Scope of ASTM E345?
This test method covers the tension testing of metallic foil at room temperature in thicknesses less than 0.006 in. (0.150 mm).
- Individual specifications or test methods may be required for a particular material.
- These test methods are utilized for the acceptance testing of commercial shipments.
- ASTM E345 can be used to test copper foil, aluminum foil, and other types of pure metal and alloy foils.
- Wedge grips or pneumatic vise grips are recommended for this test.
ASTM E345 Sample Preparation and Equipment
This test can use two specimen types: Type A and Type B. Type A specimens shall be in accordance with the 1⁄2-in. (12.5-mm) the sheet-type specimen, and Type B specimens shall be in accordance with the 1⁄2-in. (12.5-mm) wide parallel-sided specimen. A tensile testing machine and a connected computer system for recording data are used.
| Specimen Dimensions | ||
| Type A | Type B | |
| mm | mm | |
| Gauge length G | 50 | 125 |
| Width W | 12.50 | 12.5 |
| Thickness T | Thickness of foil | Thickness of foil |
| Radius of fillet R | 19 | |
| Overall Length L | 200 | 230 |
| Length of reduced section, A | 60 | |
| Length of Grip section, B | 50 | |
| Width of grip section, C | 20 | 12.5 |
ASTM E345 Testing Procedure and Requirements
ASTM E345 involves preparing Type A and Type B test specimens and measuring them for testing. Specific measurements include thickness and width. The thickness of specimens taken from soft foils or from foils 0.002 in. (0.05 mm) and thinner shall be determined to an accuracy of 2 % of the thickness by weighing. The width dimension to the nearest 0.001 in. (0.025 mm). Yield strength is measured by the Offset method and the extension-under-load method. Then the test will proceed to measure tensile strength; it is determined by dividing the maximum force carried by the specimen by the specimen’s original cross-sectional area. Then, elongation is measured for the Type A and Type B specimens using different methods. Elongation should be near 0.5 %.
ASTM E345 Results Analysis and Interpretation
Width can be calculated by,
T = W/AD
Where,
T = thickness of specimen or sample,
W = mass of specimen or sample,
A = area of specimen or sample, and
D = density of material,
