Full title and description

ASTM E1855-20 — Standard designation E1855, issued by ASTM International in 2020. This entry summarizes the scope, intent, and typical application of the E1855-20 standard. It is intended as a product/overview page; the official normative text and precise test procedures are available from ASTM International.

Abstract

ASTM E1855-20 is a published ASTM International standard (designation E1855, year 2020) that provides a standardised approach for a specific laboratory test or practice within the E-series of ASTM standards. The standard defines required apparatus, specimen preparation, test procedures, calibration and reporting conventions to ensure reproducible results across laboratories. This overview describes the standard's purpose, primary topics, intended users, and how it relates to other standards in the field.

General information

• Status: Active (published as E1855-20).
• Publication date: 2020.
• Publisher: ASTM International (formerly American Society for Testing and Materials).
• ICS / categories: Materials testing and laboratory methods; relevant to ASTM E-series test methods and practices.
• Edition / version: Designation E1855-20 (year-based suffix indicates 2020 issue/revision).
• Number of pages: Approximately 4–12 pages (depends on printing/format). For the definitive page count consult the official ASTM publication.

Scope

This standard establishes a repeatable procedure for a narrowly defined test or practice used in material characterization, product evaluation, or laboratory quality control. The scope covers definitions, required apparatus and materials, specimen conditioning, step-by-step test procedures, calibration and verification steps, calculation/reporting formats, and notes on precision and bias where provided by the committee. It is intended to produce comparable data between laboratories when followed as written.

Key topics and requirements

• Clear definition of purpose and applicability of the test/practice.
• Detailed list of required equipment, instruments and calibration requirements.
• Specimen preparation and conditioning procedures to minimise variability.
• Stepwise test methodology including timing, environmental controls, and operator actions.
• Data reduction, calculations and reporting templates (units, significant figures, acceptance criteria).
• Notes on precision, reproducibility and any known limitations or interferences.
• Safety considerations and recommended personal protective equipment.

Typical use and users

Users of E1855-20 typically include materials testing laboratories, quality control engineers, product development teams, research organisations, and certification bodies that require standardised, reproducible test data. The standard is applied when consistent test methodology is needed for comparison of materials, validation of manufacturing processes, compliance testing, or when reporting results in technical specifications and procurement documents.

Related standards

E1855-20 is part of the broader family of ASTM E-series standards and is commonly used alongside other ASTM test methods and practices relevant to laboratory procedures, sample conditioning and materials characterization. Laboratories should consult companion and general practice standards (for example, those covering equipment calibration, statistical treatment of test results, and laboratory safety) to ensure full compliance with best practices.

FAQ

Q: What is this standard?

A: ASTM E1855-20 is an ASTM International standard issued in 2020 (designation E1855) that defines a standard test method or practice used in laboratory evaluation and materials testing. This page provides an overview; the official standard text must be obtained from ASTM for authoritative details.

Q: What does it cover?

A: It covers the scope and procedures for a specific laboratory test or practice: required apparatus, specimen preparation, step-by-step methods, calibration, calculations, reporting requirements, and notes on precision and limitations. The exact technical content and step-by-step instructions are contained in the official ASTM document.

Q: Who typically uses it?

A: Testing and calibration laboratories, quality engineers, materials scientists, research organisations, and product development teams who need standardised procedures to produce reproducible test data and to support specifications, compliance and comparative evaluations.

Q: Is it current or superseded?

A: E1855-20 refers to the version published in 2020. Users should verify the current status (active, reaffirmed, revised, or withdrawn) with ASTM International or their standards administrator to confirm whether a newer revision exists.

Q: Is it part of a series?

A: Yes. The designation places it in the ASTM E-series, which groups standards related to materials testing, mechanical testing, and laboratory practices. It is common practice to use E1855-20 alongside other E-series standards and general practices for testing and reporting.
