Overview

ISO 276:2019 is an international standard published by the International Organization for Standardization (ISO) that specifies the requirements and test methods for linseed stand oil used as binders in paints and varnishes. Linseed stand oil is a polymerized form of linseed oil obtained through heat treatment, widely used for its drying and binding properties in coatings and varnish formulations. This third edition of ISO 276 updates the technical criteria and testing procedures to ensure consistent quality and performance of linseed stand oils across various applications.

Key Topics

• Scope and Types
  ISO 276:2019 covers five types of linseed stand oil differentiated primarily by viscosity-from extra-low to extra-high viscosity-to cater to diverse formulation requirements in paints and varnishes.

• Requirements
  Key quality characteristics outlined in the standard include:

  • Viscosity at 20 °C, 23 °C, and 25 °C measured in Pascal seconds (Pa·s) using ISO 12058-1 methods.
  • Turbidity, to ensure clarity and proper appearance, tested per ISO 15715, with allowances for cold-related turbidity that can be removed by heating above 40 °C.
  • Colour, assessed using the Gardner colour scale (ISO 4630), with a maximum allowed value to ensure visual consistency.
  • Acid Value, indicating the free fatty acid content, tested according to ISO 660 or ISO 2114 to assess oil quality and shelf life.
  • Saponification Value, reflecting the total fat content, measured by ISO 3657 or ISO 3681 titrimetric methods.

• Test Methods and Compliance
  The standard mandates specific test methods to evaluate the above parameters to confirm that the oil meets the defined specifications. Each batch of linseed stand oil must be verified to comply with ISO 276 to guarantee consistent performance in end-use applications.

• Reporting
  Detailed test reports are required, including product identification, test results, compliance status, any deviations from methods, and dates of testing, ensuring full traceability and quality assurance.

Applications

Linseed stand oil conforming to ISO 276:2019 plays a critical role in the manufacture of high-performance paints and varnishes. Its polymerized form improves drying times, gloss, hardness, and durability of coatings. Typical applications include:

• Protective Coatings: For wood, metal, and other surfaces requiring a durable, water-resistant finish.
• Artistic Paints: Used by artists in oil painting mediums to improve flow and finishing characteristics.
• Industrial Varnishes: Applied to machinery and equipment for enhanced corrosion protection and aesthetic appeal.
• Furniture Finishing: Provides a hard, glossy surface that enhances the natural beauty of wood while protecting it from wear and environmental damage.

Using linseed stand oil that meets ISO 276 ensures consistent binder quality, which directly influences the performance, longevity, and appearance of paints and varnishes.

Related Standards

ISO 276:2019 references and works in conjunction with several related ISO standards to ensure comprehensive quality evaluation:

• ISO 660 - Determination of acid value and acidity in animal and vegetable fats and oils.
• ISO 2114 - Determination of partial acid value and total acid value in plastics and paints.
• ISO 3657 - Determination of saponification value in fats and oils.
• ISO 3681 - Saponification value determination by titrimetric methods for binders in paints.
• ISO 4618 - Terms and definitions related to paints and varnishes for standardization consistency.
• ISO 4630 - Gardner colour scale for clear liquids.
• ISO 12058-1 - Viscosity determination using falling-ball viscometers.
• ISO 15715 - Method for determining turbidity in binders.

Compliance with ISO 276:2019 alongside these referenced standards ensures that linseed stand oil used in coatings meets internationally recognized quality and safety criteria.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
