Understanding ASTM D638 – Tensile Testing of Plastics

The ASTM D638 standard outlines the method for preparing and testing plastic specimens under tensile stress. This includes defining specimen shapes (Type I through Type V), dimensions, and acceptable tolerances.

Key Highlights of ASTM D638:

Specimen Types: Vary depending on material thickness and application
Gauge Length: Typically 50 mm for Type I specimens
Test Speed: Defined based on material type
Application: Commonly used for thermoplastics and thermosets

Kiyo R&D Center and Laboratory prepares these specimens using high-precision CNC and die cutting systems to ensure flawless conformance with ASTM norms.

ISO 527 – Determining Tensile Properties of Plastics

ISO 527 is the international counterpart that governs the tensile testing of plastics. While similar in function to ASTM D638, ISO 527 introduces different dimensions, test speeds, and procedures based on the material and intended use.

Key Aspects of ISO 527:

Specimen Shape: Type 1A is commonly used
Gauge Length: Typically 75 mm for ISO standard tests
Crosshead Speed: Defined based on elongation at break
Material Scope: Covers reinforced and non-reinforced plastics

At Kiyo R&D Center, ISO 527 test specimens are prepared under strictly controlled conditions, ensuring full compliance for credible, globally accepted results.

The Specimen Preparation Process at Kiyo R&D Center

Our tensile specimen preparation process includes the following meticulous steps:

Material Selection and Conditioning: Ensuring that raw material is representative and conditioned as per standard requirements.
Specimen Cutting: Utilizing precision dies or CNC routers to shape the specimens exactly as per ASTM D638 and ISO 527 dimensions.
Surface Finishing: Smooth edges are ensured to avoid stress concentrators that could affect test results.
Labeling and Documentation: Each specimen is coded for traceability and included in a comprehensive test batch log.
Quality Check: All dimensions are verified using calibrated measuring tools before proceeding to the testing phase.

Why Standardized Specimen Preparation Matters

Incorrect specimen dimensions, poor surface finish, or non-compliance with preparation standards can lead to skewed results. Standardization ensures:

Reproducibility of results
Global acceptance of test data
Validity in R&D, certification, and quality control

When choosing a lab for tensile specimen preparation in Chennai, insist on facilities like Kiyo R&D Center and Laboratory that understand the importance of following ASTM D638 and ISO 527 to the letter.
