Overview
The draft international standard oSIST prEN ISO 6599-1:2025:2025, titled Packaging - Conditioning for testing - Part 1: Paper sacks, specifies the procedures for conditioning empty paper sacks prior to and during testing. Developed by ISO/TC 122/SC 3 under the European Committee for Standardization (CEN), this document ensures that paper sacks reach temperature and moisture equilibrium with controlled atmospheres, thereby standardizing test conditions and improving reliability and comparability of test results.
Conditioning atmospheres and test procedures are crucial because paper properties, such as strength and durability, are significantly affected by moisture content and temperature. This standard describes the equipment, suitable conditioning environments, duration of conditioning, and proper recording practices for quality assurance during the testing of paper sacks.
Key Topics
Conditioning Atmospheres:
The standard defines specific temperature and relative humidity conditions for conditioning, including:- 23°C / 50% RH (preferred atmosphere)
- 27°C / 65% RH (for specific climatic conditions)
- 20°C / 65% RH (additional option)
Temperature and Humidity Control:
Conditioning rooms must use automatic systems to maintain uniform temperature and relative humidity with continuous air circulation to ensure all sack surfaces are exposed evenly.Conditioning Procedure:
- Paper sacks without barrier plies require a minimum conditioning duration of 24 hours.
- Paper sacks with barrier plies require at least 7 days of conditioning due to slower moisture equilibration.
- Sacks should be suspended to allow free air circulation to exterior and interior surfaces (if open).
Equipment Requirements:
The conditioning environment must have calibrated instrumentation such as recording hygrometers or calibrated wet and dry thermometers for verification.Test Reporting:
Test reports must include:- Reference to ISO 6599-1:2025 standard
- The conditioning atmosphere designation used
- Duration of conditioning
- Any deviations or unusual observations during conditioning
Applications
This standard is essential for manufacturers, testing laboratories, and quality assurance professionals working with paper sacks used in packaging applications for various industries. Proper conditioning as per ISO 6599-1:2025 helps:
- Achieve consistency in physical property measurements such as tensile strength, tear resistance, and durability of paper sacks under standardized moisture and temperature conditions.
- Ensure comparability of performance data across different batches and suppliers.
- Facilitate compliance with regulatory or client specifications that mandate standardized testing procedures.
- Improve product reliability and performance by understanding material behavior under controlled conditions.
The guidelines are valuable for industries including food packaging, chemicals, construction, and agriculture, where paper sacks are widely used for transporting powders, grains, and other bulk commodities.
Related Standards
oSIST prEN ISO 6599-1:2025:2025 works alongside and references several established ISO standards:
- ISO 187: Specifies standard atmospheres and conditioning procedures for paper, board, and pulp – foundational for this standard’s atmosphere specifications.
- ISO 554: Covers general standard atmospheres for conditioning and testing, providing specifications for temperature and relative humidity control.
- ISO 6590-1: Defines vocabulary and terms specifically for paper sacks, fostering clear communication.
These documents collectively support a comprehensive framework for packaging material testing and conditioning, ensuring harmonized methodologies and terminology globally.

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.
