ISO 6599-1:2026 - Packaging — Conditioning for testing — Part 1: Paper sacks
ISO 6599-1:2026 - Emballages — Conditionnement pour essais — Partie 1: Sacs en papier
Overview
ISO 6599-1:2026 establishes the standards for conditioning intact, empty paper sacks for testing within the packaging industry. Published by the International Organization for Standardization (ISO), this part of the ISO 6599 series outlines the required conditioning atmospheres and the procedures to ensure consistency, reliability, and reproducibility in testing paper sacks. The standard is utilized internationally by packaging manufacturers, testing labs, and quality assurance professionals to help determine the physical properties of paper sacks under controlled humidity and temperature conditions.
Proper conditioning is essential because the moisture content of paper significantly affects its mechanical and physical properties. By standardizing the conditioning process, ISO 6599-1:2026 ensures valid comparison of results across organizations.
Key Topics
Conditioning Atmospheres
Specifies temperature and relative humidity settings recommended for conditioning, including:- 23°C ±1°C / 50% ±2% RH (preferred)
- 27°C ±1°C / 65% ±2% RH
- 20°C ±1°C / 65% ±2% RH
Conditioning Method
- Samples of intact, empty paper sacks are exposed to controlled atmospheres until they reach temperature and moisture equilibrium.
- Sacks are suspended to allow free air circulation to all surfaces.
Minimum Conditioning Periods
- Sacks without barrier plies: at least 24 hours.
- Sacks with barrier plies: at least 7 days.
Equipment Requirements
- Conditioning rooms must be equipped to maintain uniform temperature and humidity, monitored with regularly calibrated recording hygrometers.
Reporting Requirements
- The test report must detail relevant parameters such as the atmosphere used, conditioning duration, deviations from the procedure, and observed anomalies.
Applications
ISO 6599-1:2026 is widely applicable within the packaging industry, particularly for manufacturers and laboratories involved in the production and testing of paper sacks. Typical uses include:
Quality Assurance
Ensures that paper sacks meet performance requirements under standardized conditions before shipment.Product Development & R&D
Provides a reliable basis for comparing sack materials or designs, supporting innovation and material selection.Regulatory & Compliance Testing
Helps manufacturers and exporters demonstrate product consistency and compliance with international requirements.Interlaboratory Testing
Facilitates consistent sample preparation and testing conditions across different laboratories, supporting the accuracy of comparative evaluations.
Reliable conditioning as specified in ISO 6599-1:2026 minimizes test variability and supports the fair assessment of physical attributes such as strength, durability, and resistance to environmental factors.
Related Standards
Organizations seeking comprehensive guidance may refer to these additional standards:
- ISO 187:2022 - Paper, board, and pulps - Standard atmosphere for conditioning and testing and procedure for monitoring the atmosphere and conditioning of samples
- ISO 6590-1 - Packaging - Vocabulary - Part 1: Paper sacks (for terminology)
- Related documents in the ISO 6599 series addressing other types of packaging and further procedures for conditioning and testing
By adhering to ISO 6599-1:2026 and its related standards, professionals ensure robust, consistent, and internationally accepted testing procedures for paper packaging materials. Following these guidelines is essential for maintaining high product quality, regulatory compliance, and facilitating international trade in packaging products.
