ISO 9117-1:2009 specifies a test method for determining under standard conditions whether a single coat or a multi-coat system of paint, varnish or related material has reached the through-dry state after a specified drying period.
The test procedure may also be used to determine the time taken to achieve that state.
Beschichtungsstoffe - Trocknungsprüfungen - Teil 1: Bestimmung des Durchtrocknungszustandes und der Durchtrocknungszeit (ISO 9117-1:2009)
Diese Internationale Norm gehört zu einer Reihe von Normen, welche die Probenahme und die Prüfung von Lacken, Anstrichstoffe und ähnlichen Beschichtungsstoffen behandelt. Sie legt ein Prüfverfahren fest, nach dem bestimmt werden kann, ob ein Ein- oder Mehrschichtsystem eines Anstrichstoffes oder eines ähnlichen Beschichtungsstoffes unter Standardbedingungen nach einer festgelegten Trocknungszeit den Durch¬trocknungszustand erreicht hat, d. h. eine ja/nein-Prüfung. Das Prüfverfahren kann auch dazu benutzt werden, die für die Erreichung dieses Zustandes erforderliche Zeit zu bestimmen.

L'ISO 9117‑1:2009 spécifie une méthode d'essai permettant de déterminer, dans des conditions normalisées, si un système monocouche ou multicouche de peinture, vernis ou produit assimilé a atteint l'état sec à cœur, après un temps de séchage spécifié.
Il est également possible d'utiliser cette méthode d'essai pour déterminer le temps nécessaire pour atteindre cet état.

Overview
EN ISO 9117-1:2009 - Paints and varnishes - Drying tests - Part 1: Determination of through-dry state and through-dry time (ISO 9117-1:2009) defines a standardized test method to assess whether a single coat or multi-coat coating has reached a through-dry state after a specified drying period. The procedure can also be used to determine the through-dry time (the elapsed time from application to through-dry). This European adoption by CEN provides harmonized laboratory conditions for quality control, product development and specification compliance.
Key topics and technical requirements
- Scope and purpose: Establishes how to determine if a coating is dry throughout its thickness under standard conditions; optionally used to find the time to reach that state.
- Test principle: A coated test panel is subjected to a controlled local load (gauze over a rubber disc) for a specified period and then rotated 90°; the film is examined for damage to judge through-dry state.
- Apparatus and materials:
- Baseplate and free-sliding plunger with plunger head (≥25 mm diameter).
- Rubber disc: ~22 mm diameter, ~5 mm thick, hardness ~50 ±5 IRHD.
- Woven monofilament polyamide gauze (specified thread/aperture), fresh for each test.
- Weights to give a total mass of approximately 1 500 g and a stopwatch.
- Test panels and sampling: Use representative samples per ISO 15528; prepare panels per ISO 1514 and ISO 1513. Typically three panels are used (six if both state and time are determined).
- Procedure essentials:
- Dry/age panels horizontally with free air circulation, shielded from drafts/direct sunlight under specified conditions.
- Apply gauze/plunger, load for (10 ± 1) s, rotate plunger head 90° in ~2 s, then inspect visually.
- Repeat on additional panels; report “through-dry state achieved” or “not achieved”.
- Reporting: Include coating method, dry film thickness, drying/stoving and aging conditions, and the test result. Film thickness measurement references ISO 2808.
Practical applications and users
- Who uses it: Paint and varnish manufacturers, QC/QA laboratories, coating formulators, industrial applicators, specifiers and certification bodies.
- Why it’s used:
- Routine quality control to confirm a batch or coating process produces a through-dry film.
- Comparative evaluation during product development and formulation optimization.
- Contract/specification compliance checks and acceptance testing for single- and multi-coat systems.
- Supporting data for performance claims (e.g., handling, stacking, further processing).
- Practical tips: Follow referenced standards for sampling, panel preparation and thickness measurement; use fresh gauze each test and ensure stable drying conditions as agreed between parties.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 9117-1 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 9,
General test methods for paints and varnishes, in collaboration with CEN/TC 139, Paints and varnishes.
It cancels and replaces ISO 9117:1990, which has been technically revised. The main changes are:
a) failure is defined in terms of damage, rather than damage or marking;
b) the former Annex A concerning required supplementary information has been integrated in the test report.
