ASTM D2289-84 PDF

Full title and description

ASTM D2289-84 — "Method of Test for Tensile Properties of Plastics at High Speeds". This test method establishes procedures for measuring tensile properties of plastics over a broad range of testing speeds, extending from conventional tensile test speeds to speeds at which stress‑wave propagation and high strain‑rate effects become important.

Abstract

Provides a short, standardized test procedure to obtain tensile stress‑strain behavior of moulding and extrusion plastics at elevated test speeds. The method describes specimen preparation, apparatus requirements for high‑speed tensile machines, recommended speed ranges, conditioning, measurement and reporting of results. The intention is to capture rate‑dependent tensile properties relevant to impact and crash‑type loading situations.

Scope

Specifies a tensile test method for plastics at high testing speeds (high strain rates), intended to determine tensile strength, elongation at break and rate‑dependent characteristics where conventional slow‑speed tests (for example ASTM D638) may not represent performance under dynamic or impact conditions. The standard covers specimen configuration, machine and gripping requirements for high‑speed machines, selection of test speeds, and recommended reporting.

Key topics and requirements

• Specified range of test speeds and strain‑rate definition (to capture static through high‑speed regimes).
• Recommended specimen types and dimensions for reproducible dynamic tensile results.
• Apparatus and machine performance requirements for high‑speed tensile testing (hydraulic/high‑energy systems, dynamic force measurement, grips).
• Conditioning and environmental control prior to testing to ensure comparability.
• Calibration, data acquisition rates, and checks for stress‑wave and inertial effects.
• Data reduction, reporting of tensile strength, modulus (where applicable), elongation, and clear statement of test speed/strain rate.
• Safety and machine‑guarding considerations for high‑energy dynamic tests.

Typical use and users

Used historically by materials laboratories, plastics manufacturers, automotive and aerospace R&D groups, and testing houses performing dynamic or impact‑relevant tensile characterization. Typical users include quality control engineers, materials scientists, product designers requiring high‑strain‑rate mechanical data, and academic researchers studying rate‑dependent behavior of polymers.

Related standards

Closely related to ASTM D638 (standard tensile test for plastics at conventional speeds) and ASTM D618 (conditioning of plastics for testing). International and industry standards addressing high strain‑rate tensile testing include ISO 18872 (tensile properties at high strain rates), ISO 8256 (tensile‑impact), SAE J2749 and VDA recommendations for dynamic tensile testing; these are commonly used or referenced in place of older withdrawn procedures.

FAQ

Q: What is this standard?

A: ASTM D2289-84 is a test method titled "Method of Test for Tensile Properties of Plastics at High Speeds" that provided procedures for measuring tensile behavior of plastics under elevated testing speeds and strain rates.

Q: What does it cover?

A: It covers specimen selection, high‑speed tensile apparatus requirements, recommended test speeds/strain rates, conditioning, data acquisition and reporting to characterize rate‑dependent tensile properties relevant to impact and dynamic loading.

Q: Who typically uses it?

A: Materials test laboratories, plastics and polymer manufacturers, automotive and aerospace R&D, and academic researchers interested in high‑strain‑rate mechanical behavior of plastics. It served users needing tensile data beyond conventional (low speed) test regimes.

Q: Is it current or superseded?

A: ASTM D2289-84 was withdrawn (withdrawal recorded in 1990) and is not an active ASTM standard. For contemporary work on high‑rate tensile behavior, practitioners commonly use later or international standards such as ISO 18872, SAE J2749, ISO 8256 or relevant ASTM practice/standards that address dynamic testing and specimen conditioning.

Q: Is it part of a series?

A: It belongs to the ASTM D series covering plastics test methods and is conceptually linked with other tensile and conditioning standards (for example ASTM D638 and ASTM D618). While D2289-84 itself was a standalone test method, it complements the broader family of mechanical test standards for plastics.

Q: What are the key keywords?
