ASTM D3359-23 PDF

Full title and description

Standard Test Methods for Rating Adhesion by Tape Test — procedures (two test methods, A and B) for assessing the adhesion of relatively ductile coating films to metallic substrates by applying and removing pressure‑sensitive tape over cuts made through the film to the substrate.

Abstract

ASTM D3359-23 defines two simple, widely used tape/knife adhesion tests — Method A (X‑cut) and Method B (cross‑cut lattice) — to provide a qualitative rating of coating adhesion on a 0–5 scale. The methods are intended primarily for coated metallic substrates and are intended to indicate whether adhesion is adequate for a user’s application rather than to produce precise bond‑strength values.

Scope

These test methods cover procedures for assessing adhesion of relatively ductile coating films to metallic substrates by scoring the film and applying/removing pressure‑sensitive tape. Test Method A (X‑cut) is primarily intended for coatings and coating systems greater than 125 μm (5 mils) total thickness; Test Method B (cross‑cut lattice) is primarily intended for coatings less than 125 μm (5 mils), using 6 or 11 cuts in each direction depending on film thickness. The methods provide a qualitative ranking (0–5) and are not intended to provide precise quantitative bond‑strength values.

Key topics and requirements

• Two test methods: Method A (X‑cut) and Method B (cross‑cut lattice).
• Thickness guidance: Method A for >125 μm (5 mils); Method B for ≤125 μm (with 1 mm or 2 mm spacing options — 11 cuts for thin films, 6 cuts for thicker thin films).
• Rating scale: 0–5 (often represented as 0A–5A or 0B–5B depending on method) based on amount of coating removed by tape.
• Test apparatus and technique requirements: sharp cutting tool/blades or templates for consistent cuts, specified tape application and dwell/removal method, and controlled peel angle/rate; operator skill and tape selection materially affect results.
• Limitations: primarily intended for metal substrates and relatively ductile coatings; not sensitive to fine differences in high adhesion levels; tape choice, substrate, environment and operator technique influence outcomes.

Typical use and users

Used by coatings manufacturers, quality control and production teams, independent test laboratories, NDT/inspection staff, and field technicians to quickly screen adhesion performance of paint and organic coatings on metal substrates. Commonly used for acceptance testing, incoming inspection, process control and field checks where a rapid qualitative adhesion assessment is required.

Related standards

Related and comparable methods include ISO 2409 (cross‑cut test), and other ASTM practices referenced in D3359 such as Practice D7091 (dry film thickness measurement) and other preparation/specification standards for substrates and coatings. Users often apply D3359 alongside substrate preparation and coating test standards to interpret results.

FAQ

Q: What is this standard?

A: ASTM D3359-23 is a standardized pair of tape/knife adhesion test methods (Method A and Method B) for rating the adhesion of coating films to metallic substrates on a qualitative 0–5 scale.

Q: What does it cover?

A: It covers procedures for making controlled cuts through a cured coating, applying pressure‑sensitive tape, removing the tape under prescribed conditions, and rating the amount of coating removed to assess adhesion; Method A (X‑cut) is for thicker coatings, Method B (cross‑cut) for thinner coatings (with specific cut counts and spacing).

Q: Who typically uses it?

A: Coatings manufacturers, QC/production labs, independent testing labs, inspectors, and field technicians who need a quick, repeatable adhesion screening test.

Q: Is it current or superseded?

A: D3359-23 is the current active edition (approved Feb 1, 2023; published by ASTM in 2023) and revises the prior D3359-22 edition.

Q: Is it part of a series?

A: It is maintained under ASTM Committee D01 (Paint and Related Coatings, Materials, and Applications), Subcommittee D01.23, and is part of the suite of ASTM standards for paint/coating testing and inspection; several complementary ASTM practices and test methods are often used together with D3359.

Q: What are the key keywords?

A: Adhesion, tape test, cross‑cut, X‑cut, pressure‑sensitive tape, film thickness, coating inspection, ASTM D3359.
