Full title and description

St ISO 3039-1975 rus — "Corrugated fibreboard — Determination of the grammage of the component papers after separation" (original ISO title). This document specifies a test method for determining the surface mass (grammage) of the individual papers from which corrugated fibreboard is made, after the component papers have been separated.

Abstract

The standard defines sampling, conditioning, separation of component layers, drying and weighing procedures and calculation of grammage for test pieces (minimum area specified) so that the grammage of each component paper can be determined. It is applicable to all types of corrugated fibreboard and references ISO/R 186, ISO 187 and ISO 536 for sampling, conditioning and grammage determination procedures.

Scope

This method applies to all types of corrugated fibreboard. It covers preparation of specimens taken from unprinted/uncoated areas where possible, separation of component papers, conditioning (per ISO 187), drying where required, and determination of grammage by weighing test pieces of defined area (reference method ISO 536). The procedure is intended to provide the grammage of each constituent paper layer after separation.

Key topics and requirements

• Sampling of corrugated fibreboard specimens (reference to ISO/R 186).
• Preparation and minimum dimensions of test pieces (specified minimum area for accuracy).
• Separation technique for component papers without altering mass.
• Conditioning and drying requirements prior to weighing (ISO 187 referenced).
• Weighing accuracy and equipment sensitivity required to determine grammage to the stated precision.
• Calculation method to convert measured mass and area to grammage (g·m−2) following ISO 536 principles.

Typical use and users

Laboratories and quality-control departments in corrugated board and paperboard manufacturing, packaging testing laboratories, converters and procurement/specification teams use this method to verify constituent paper grammages, investigate board composition, support recycling/quality claims and for conformity testing in procurement or research. National standards bodies and test houses reference the method when assessing layered board composition.

Related standards

ISO 3039:1975 was later revised and replaced by ISO 3039:2010 (new edition covering the same subject with expanded details). The 1975 method also cross-references ISO/R 186 (sampling of paper/board), ISO 187 (conditioning of test samples) and ISO 536 (determination of grammage). Several national adoptions or related national standards (for example regional standards/DSTU or GOST adaptations) have been issued referencing ISO 3039:1975.

FAQ

Q: What is this standard?

A: ISO 3039:1975 is an ISO test method titled "Corrugated fibreboard — Determination of the grammage of the component papers after separation" that describes how to separate component papers from corrugated board and determine their grammage.

Q: What does it cover?

A: It covers specimen preparation, separation of layers, conditioning/drying, weighing and calculation procedures to obtain the grammage (g·m−2) of each constituent paper layer of corrugated fibreboard. The method refers to ISO/R 186, ISO 187 and ISO 536 for sampling, conditioning and basic grammage determination details.

Q: Who typically uses it?

A: Packaging manufacturers, paper and board mills, independent testing laboratories, quality assurance teams, researchers and standards bodies use the method to verify the composition and constituent paper masses of corrugated board. Typical use cases include material specification checks, failure analysis and recycling classification.

Q: Is it current or superseded?

A: The 1975 edition has been withdrawn and superseded by ISO 3039:2010 (the later edition provides the current published method). Users requiring the up-to-date text should consult ISO 3039:2010.

Q: Is it part of a series?

A: It is part of the body of ISO standards for paper and board testing under ISO/TC 6 and is related to other ISO methods for sampling, conditioning and grammage measurement (ISO/R 186, ISO 187, ISO 536) and to national adoptions/translations of the method.

Q: What are the key keywords?

A: corrugated fibreboard, grammage, component papers, separation, paper testing, ISO 3039.
