Full title and description

ASTM G190-15 — Standard Guide for Developing and Selecting Wear Tests. A brief ASTM guide that provided general information and recommended considerations for developing and selecting laboratory wear tests appropriate to an intended application, without prescribing a single test method or procedure.

Abstract

This guide (G190-15) summarized factors to consider when designing or choosing wear tests — e.g., intended wear mechanism, contact geometry, loads, environment, lubrication, test duration, measurement and data reporting — and emphasized that selection/development requires expert judgment rather than a one-size-fits-all flowchart. The document was concise (5 pages) and intended as general guidance rather than a prescriptive test standard.

General information

• Status: Withdrawn (withdrawn without replacement by ASTM in 2021).
• Publication date: May 1, 2015 (designated G190-15).
• Publisher: ASTM International (Committee G02 — Wear and Erosion).
• ICS / categories: 19.020 — Test conditions and procedures in general.
• Edition / version: G190-15 (2015 edition).
• Number of pages: 5 pages.

Scope

This guide covered general information for the development and selection of a wear test for an intended application. It did not define specific test procedures; rather it described key elements and decision factors to help an expert design or choose an appropriate wear test. The guide was withdrawn in November 2021 because the committee concluded it did not provide sufficiently useful, prescriptive guidance for selecting a particular wear test and overlapped with more detailed resources.

Key topics and requirements

• Overview of wear mechanisms and matching test design to expected mechanism (abrasive, adhesive, fretting, erosive, tribochemical, etc.).
• Considerations for contact geometry and kinematics (point, line, area contacts; sliding, rolling, reciprocating motion).
• Loading conditions: static vs dynamic loads, contact pressure, and load control methods.
• Environment and lubrication: dry vs lubricated testing, temperature, humidity, corrosive media.
• Specimen preparation, alignment, reproducibility, and statistical considerations for repeatability and uncertainty.
• Measurement and reporting recommendations: wear metrics (mass loss, volume loss, wear rate), surface characterization, and test duration/endpoint selection.
• Guidance-level (non-prescriptive): the guide recommends expert judgment rather than providing a single selection tree or mandatory procedures.

Typical use and users

Intended users were tribologists, materials and mechanical engineers, laboratory test developers, and quality/assessment engineers who need high-level guidance when planning wear testing programs. Because the guide was brief and non-prescriptive, users seeking detailed test methods were expected to consult specific ASTM wear test methods, specialized manuals, or technical literature.

Related standards

Related ASTM items and resources include detailed wear test methods and terminology standards maintained by Committee G02 (examples: G99 — Pin-on-Disk, G133 — Linear Reciprocating Wear, and G40 — Terminology relating to wear and erosion) and the ASTM Manual MNL 56 (Guide to Friction, Wear, and Erosion Testing) by Ken Budinski, which the committee cited as a more comprehensive reference. Note that G190 was withdrawn without replacement; users should reference active, specific wear test standards for prescriptive procedures.

FAQ

Q: What is this standard?

A: ASTM G190-15 was a short guide titled "Standard Guide for Developing and Selecting Wear Tests" that provided high-level guidance for choosing or developing laboratory wear tests.

Q: What does it cover?

A: It covered general considerations — wear mechanisms, contact geometry, loading, environment/lubrication, specimen preparation, measurement and reporting — but did not prescribe specific test procedures.

Q: Who typically uses it?

A: Tribologists, materials engineers, test lab personnel and others planning wear testing programs who want a concise checklist of factors to consider. For detailed procedures, users are expected to rely on specific ASTM test methods or comprehensive manuals.

Q: Is it current or superseded?

A: G190-15 is withdrawn — the ASTM record shows the guide was withdrawn in November 2021 and the committee determined it had limited utility for selecting specific tests; it was withdrawn without a direct replacement.

Q: Is it part of a series?

A: G190 was maintained under ASTM Committee G02 (Wear and Erosion) alongside many specific wear test standards and terminology standards, but it was a standalone guide rather than one of a numbered prescriptive-method series.

Q: What are the key keywords?

A: Wear testing, tribology, test selection, wear mechanisms, erosion, ASTM, test development, G190.
