ASTM D6195-22 PDF

Full title and description

ASTM D6195-22 — Standard Test Methods for Loop Tack. This document specifies two standardized procedures for measuring the loop tack (quick-stick) of pressure‑sensitive adhesives using either a tensile tester (Test Method A) or a dedicated loop tack tester (Test Method B). The test quantifies the maximum force required to separate a formed adhesive loop from a 1 in.² stainless‑steel contact area under controlled conditioning and test speeds.

Abstract

These test methods provide a repeatable, quantitative measure of the initial bonding or tack of pressure‑sensitive adhesive articles (tapes, labels, transfer adhesives, etc.). Specimens are formed into a loop with adhesive outwards, contacted lightly to a standardized stainless‑steel surface, then removed; the peak removal force is recorded and reported, typically as an average of multiple replicates for quality control and R&D use.

Scope

Provides two test methods for loop tack measurement: Test Method A (using a tensile tester with a 175 mm specimen strip) and Test Method B (using a loop tack tester, typically with a 125 mm strip). The specimen loop is contacted to a 1 in. × 1 in. (25 mm × 25 mm) stainless‑steel surface and removed; the peak force required for separation is recorded. The methods include specimen preparation, conditioning, surface cleaning, test speed and reporting conventions used for quality control, product development, and comparative testing.

Key topics and requirements

• Test methods: Test Method A (tensile tester) and Test Method B (loop tack tester) for different equipment setups.
• Contact area: 1 in.² (25 × 25 mm) stainless‑steel adherend (specified stainless steel grades per referenced ASTM materials).
• Specimen sizes: typical lengths 175 mm (Test A) and 125 mm (Test B) with nominal widths (commonly 25 mm / 1 in).
• Conditioning: standard conditioning at 23 ± 2 °C (73 ± 3.6 °F) and 50 ± 5 % RH for at least 24 hours unless otherwise specified.
• Test speed: commonly performed at 12 in/min (300 mm/min) for descent and withdrawal unless otherwise noted.
• Reporting: record peak removal force, mode of failure, and average (with number of replicates — typically three or more) plus any deviations from standard conditions.
• Referenced practices: cross‑references to ASTM practices for force verification and interlaboratory precision (for example, E4, E177, E691) and related adhesive/label industry standards.

Typical use and users

Used by adhesive and tape manufacturers, label producers, quality control and R&D laboratories, converters, and test labs to characterize the quick‑stick (tack) of pressure‑sensitive adhesives for product development, incoming inspection and specification compliance. Common application areas include packaging tapes, self‑adhesive labels, medical tapes/dressings, electronics tapes/films, and automotive adhesive films.

Related standards

Referenced and related documents commonly cited with D6195 include: ASTM E4 (force verification), E177 (precision and bias), E691 (interlaboratory precision practice), ASTM A666 (stainless steel specification for test panels), FINAT FTM‑9 (Quick‑Stick) and industry loop tack tests from TLMI (L‑IB1 / L‑IB2). These documents provide complementary procedures, materials and precision guidance.
