Full title and description

ASTM E2015-04 (2021) — Standard Guide for Preparation of Plastics and Polymeric Specimens for Microstructural Examination. This guide provides recommended procedures and practical guidelines for sectioning, mounting, grinding, polishing, etching, and handling of plastic and polymeric specimens intended for microstructural examination by light and electron microscopy.

Abstract

This ASTM guide describes general, widely applicable specimen‑preparation practices for most semi‑rigid and rigid plastics (and some non‑rigid plastics) to produce reproducible, artifact‑free microstructures suitable for optical and electron‑microscopy. It outlines selection of techniques, mounting methods, mechanical and chemical polishing, and precautions to avoid thermal, mechanical, or chemical alteration during preparation.

Scope

This guide covers recommended procedures and guidelines for preparation of plastic and polymeric specimens for microstructural examination by light and electron microscopy. It is applicable to most semi‑rigid and rigid plastics (including many engineering plastics) and to some non‑rigid plastics. The guide gives general, commonly successful methods but does not prescribe every variation needed for all materials or specialized problems; users must adapt procedures to the material’s properties and the intended microscopy techniques.

Key topics and requirements

• Specimen sectioning: recommended cutting methods to minimize heating and mechanical damage.
• Mounting practices: selection of mounting media and methods appropriate for polymers.
• Grinding and polishing sequences: abrasive types, cloths, and stepwise procedures to achieve a suitable surface finish without introducing artifacts.
• Chemical and mechanical polishing considerations for different polymer classes.
• Etching and contrast enhancement suitable for optical and electron microscopy.
• Precautions to avoid thermal, mechanical, or chemical alteration during preparation and to produce reproducible results.
• Guidance for selecting procedures based on material properties and the microscopy technique to be used.

Typical use and users

Used by materials scientists, metallographers, polymer technologists, quality control laboratories, forensic and failure‑analysis engineers, research laboratories, and academic groups that perform microstructural analysis of polymeric materials. Typical applications include failure investigation, product development, quality assurance, and research into structure–property relationships of plastics and composites.

Related standards

Commonly referenced or complementary standards include ASTM E3 (Standard Guide for Preparation of Metallographic Specimens), ASTM E1558 (Standard Guide for Electrolytic Polishing of Metallographic Specimens), ASTM E2014 (guidance on metallographic laboratory safety and related practices), and terminology/definition standards such as ASTM E7; other polymer‑specific practices (for example D‑series methods) may also be relevant.
