ASTM E8 Overview: Metal Tensile Testing with ADMET Systems

In this video, we break down ASTM E8, a standard for tension testing of metallic materials, and what it takes to run the test from start to finish. We cover the ADMET universal testing systems best suited for E8 testing, the types of metal samples and specimen geometries used, why and where E8 testing is applied across industries, and a complete demonstration of sample setup, pulling the specimen to break, and reading the resulting test data.

Frequently Asked Questions

ASTM E8 (Standard Test Methods for Tension Testing of Metallic Materials) and ASTM A370 (Standard Test Methods and Definitions for Mechanical Testing of Steel Products) are both widely used tensile testing standards, but they differ in scope and application:

ASTM E8 covers tension testing procedures for metallic materials broadly including steel, aluminum, copper, and other alloys. It defines specimen geometries, testing speeds, and calculation methods for properties like yield strength, tensile strength, elongation, and reduction of area.

ASTM A370 is specific to steel products and references ASTM E8 for its core tension testing procedures, but adds requirements unique to steel such as bend testing, hardness testing, impact (Charpy) testing, and product-specific specimen requirements for bar, plate, tubing, and wire.

In short: ASTM E8 is the general tension-testing methodology, while ASTM A370 is a steel-specific standard that incorporates E8’s tension testing methods alongside additional mechanical test methods (bend, hardness, impact) needed to fully qualify steel products.

ASTM E8 (Standard Test Methods for Tension Testing of Metallic Materials) and ISO 6892-1 (Metallic Materials, Tensile Testing, Part 1: Method of Test at Room Temperature) are the two most widely used tensile testing standards worldwide: E8 in the U.S. and ISO 6892-1 internationally.

The core methods are similar, but they differ in specifics: strain rate control (E8 allows crosshead speed or strain rate methods depending on the phase of test, while ISO 6892-1 defines strain-rate-controlled methods more strictly, including specific rate ranges for the elastic and plastic regions), specimen dimension tolerances, and terminology (for example, “percent elongation” in E8 vs. “percentage elongation after fracture” in ISO 6892-1).

In short: ASTM E8 and ISO 6892-1 test the same mechanical properties using broadly similar setups, but differ in strain-rate control requirements, specimen tolerances, and terminology, so results from one standard aren’t always directly interchangeable without verifying the testing parameters used.

Mechanical wedge grips are the most common choice for tensile testing metals, as their self-tightening wedge action increases clamping force as the load increases, providing a secure hold on rigid metal specimens throughout the test. For higher-volume or higher-force testing, hydraulic wedge grips offer faster, more consistent clamping with less operator variability.

The right grip also depends on specimen geometry: flat metal coupons typically use flat-faced wedge grips, while round bar or rod specimens require V-groove or notched-face wedge grips to prevent slipping. Grip selection should always match the specimen’s material, thickness, and expected load to ensure accurate, safe results.

Yes. ADMET offers both environmental chambers and high-temperature furnaces for materials testing across a wide range of temperatures.

ADMET environmental chambers can be configured for elevated- and low-temperature testing, with standard temperature ranges from -80°C up to +280°C or +350°C. For more extreme temperatures, ADMET’s high-temperature split tube furnaces operate from 300°C up to 1700°C and can be used for tensile, compression, bend, and fatigue testing.

ADMET also offers the grips, fixtures, pull rods, cooling accessories, and high-temperature extensometers needed to configure a complete testing system for your application.

The appropriate solution depends on your required temperature range, material, specimen geometry, test method, and applicable testing standard.

Yes. ADMET’s grips and fixtures are built to work with virtually any manufacturer’s test frame, so custom fixturing isn’t limited to ADMET-branded systems. We start by understanding your specific application, including material, specimen geometry, and test method, to guide you to the right fixture design and help avoid common issues like slippage, misalignment, and inconsistent results. If you’re unsure how a fixture or grip will perform on your specimen, we also offer sample testing. Send us your samples, and our engineers will test them using our range of grip solutions to help you move forward with confidence.

Yes. ADMET testing systems can be configured to accurately test miniature, thin, and fragile metal specimens using appropriately sized load cells, precision grips, fixtures, and extensometers.

Whether you’re testing thin sheet metal, fine wire, micro-scale tensile specimens, or other challenging sample geometries, ADMET can recommend the right testing system configuration for your application.

For unique specimen sizes, shapes, or materials, our engineer can also design custom grips, fixtures, and testing solutions to help ensure accurate and repeatable results.

Yes. ADMET’s MTESTQuattro software can automate the control, data collection, calculations, and reporting required for ASTM E8 tensile testing.

The software can control the prescribed loading or strain rates, acquire load, position, and extensometer data, and transition between control stages during the test. MTESTQuattro can control the test by extensometer strain rate through yield and then automatically switch to crosshead position control after the extensometer is removed. The software will also calculate and report whichever ASTM results you prefer to see on your report.

Yes. ADMET is accredited to ISO/IEC 17025:2017 by A2LA (cert # 7128.01). ADMET offers calibration services to customers who operate both ADMET equipment and systems made by other manufacturers. Below is a partial list of internationally recognized procedures

ADMET follows to calibrate testing equipment:
– ASTM E4 – Tension/Compression Force Calibration
– ASTM E2309 – Crosshead Displacement Calibration
– ASTM E2658 – Crosshead Speed Calibration
– ASTM E83 – Extensometer Calibration
