Full title and description

ISO 2813:1994 — Paints and varnishes — Determination of specular gloss of non-metallic paint films at 20°, 60° and 85°. This edition specifies a reflectometer-based test method for measuring specular gloss of non‑metallic coatings using three geometries (20°, 60° and 85°). It includes Technical Corrigendum 1 (1997).

Abstract

The standard defines procedures, instrument geometries and reporting conventions for the measurement of specular gloss on plane, opaque, non‑textured paint films. The 60° geometry is the general-purpose measurement; 20° is recommended for high‑gloss films and 85° for low‑gloss films. The method is not intended for metallic paints.

Scope

This test method specifies the measurement of specular gloss of non‑metallic paint and varnish films on plane, opaque substrates using a reflectometer at 20°, 60° and 85° geometries. It provides guidance on instrument aperture, specimen preparation, measurement procedure, calibration and reporting. It excludes measurement of metallic (effect) paints.

Key topics and requirements

• Measurement geometries: 20°, 60° and 85° and when to use each geometry (20° for high gloss; 60° general; 85° for low gloss).
• Instrument and aperture specifications, calibration against gloss standards and zero reference.
• Specimen conditioning, surface preparation and recommended number of readings/locations per specimen.
• Reporting format including geometry used, instrument type, number of readings, mean value and any deviations or remarks.
• Limitations: not suitable for metallic or strongly textured coatings; visual assessment may differ from instrument measurements.

Typical use and users

Used by paint and coating manufacturers, quality control laboratories, test houses, automotive and industrial coating specifiers, contractors and research institutes to quantify surface gloss for quality control, product development and specification compliance. It is applied where reproducible, comparable numeric gloss values are required.

Related standards

Related documents and standards include later editions (ISO 2813:2014), regional/adopted versions (EN ISO 2813 series), and other coatings test methods such as haze measurement (ISO 13803) and various national equivalents (e.g., GB/T standards).

FAQ

Q: What is this standard?

A: An ISO international standard (ISO 2813:1994) that specifies a method to determine the specular gloss of non‑metallic paint and varnish films at three geometries (20°, 60°, 85°).

Q: What does it cover?

A: Procedures for instrument geometry, calibration, specimen preparation, measurement technique and reporting for specular gloss measurements; it excludes metallic and strongly textured coatings.

Q: Who typically uses it?

A: Coatings manufacturers, QC and R&D laboratories, test houses, specification writers, and industries (automotive, furniture, architectural) that require objective gloss measurement.

Q: Is it current or superseded?

A: ISO 2813:1994 has been withdrawn and superseded by ISO 2813:2014 (later consolidated edition). For current requirements and the expanded content, refer to ISO 2813:2014.
