Overview
EN ISO 6599-1:2026 - Packaging - Conditioning for testing - Part 1: Paper sacks is a key international standard developed by CEN and ISO. This document defines the conditioning atmospheres and the prescribed procedures for conditioning samples of intact, empty paper sacks before and during testing. Proper conditioning ensures that all paper sacks tested are in a consistent physical state, allowing for accurate and comparable test results. Moisture content and temperature have a significant impact on the physical properties of paper, making this standard vital for reliable packaging testing and performance assessments.
Key Topics
- Conditioning Atmospheres: Specifies standardized temperature and humidity levels, including preferred atmospheres such as 23°C/50% RH, to equilibrate paper sack samples before testing.
- Conditioning Method: Outlines how to suspend and expose sacks to controlled conditions to achieve equilibrium between the sack’s materials and the atmosphere.
- Minimum Conditioning Periods:
- At least 24 hours for sacks without barrier plies.
- At least 7 days for sacks with one or more barrier plies, due to different moisture absorption characteristics.
- Equipment Requirements:
- Conditioning rooms equipped with precise temperature and humidity control systems.
- Use of calibrated instruments for monitoring and recording environmental conditions.
- Reporting Requirements:
- Documents the atmosphere used, the conditioning duration, and any deviations or observations during the process.
Applications
This standard has broad practical applications for laboratories, manufacturers, and quality assurance in the packaging industry, specifically for paper sacks. Key uses include:
- Testing Consistency: By bringing all samples to a standardized state, test results such as strength, durability, and moisture resistance become reliably comparable.
- Product Development: Packaging designers and engineers use this conditioning method to predict how paper sacks will behave in different climates or storage conditions.
- Quality Control: Ensures batches of paper sacks meet specified performance criteria by eliminating variability caused by uncontrolled environmental factors.
- Regulatory Compliance: Helps manufacturers and testing facilities align with both national and international packaging regulations, supporting market access and customer confidence.
Related Standards
EN ISO 6599-1:2026 references and aligns with several other important standards for packaging and material testing:
- ISO 187: Paper, board and pulps - Standard atmosphere for conditioning and testing and procedure for monitoring the atmosphere and conditioning of samples.
- ISO 554: Standard atmospheres for conditioning and/or testing - Specifications.
- ISO 6590-1: Packaging - Vocabulary - Part 1: Paper sacks.
These related standards provide the necessary framework for environmental control, terminology, and test atmosphere requirements that support the consistent conditioning and evaluation of paper-based packaging.
By adhering to EN ISO 6599-1:2026, stakeholders in the packaging industry can maintain high standards of testing accuracy and product quality, addressing both technical and regulatory demands for paper sacks used worldwide.

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.
