This document specifies the conditioning atmospheres and the method for conditioning samples of intact, empty paper sacks before and during testing.
Emballages — Conditionnement pour essais — Partie 1: Sacs en papier
La présente partie de l'ISO 6599 spécifie les atmosphères et la méthode de conditionnement des échantillons de sacs en papier, intacts et vides, avant et au cours des essais. Si uniquement des essais conventionnels sur papier doivent être faits sur le matériau du sac, des échantillons de matériau doivent être découpés et conditionnés comme spécifié dans l'ISO 187. La présente partie de l'ISO 6599 est applicable à tous les types de sacs en papier, vides, tels que spécifiés dans l'ISO 6590/1.

Overview
ISO/FDIS 6599-1:2026 is an international standard developed by ISO that provides clear guidelines for conditioning paper sacks prior to testing. Proper conditioning ensures that physical testing of empty, intact paper sacks yields accurate, consistent, and comparable results. The standard defines the required atmospheres (temperature and humidity), describes the appropriate equipment, specifies procedures for conditioning, and outlines the minimum time periods needed for equilibrium before testing is performed.
Standardized conditioning is critical because the physical properties of paper sacks, including strength and durability, are highly sensitive to moisture content. Achieving temperature and moisture equilibrium under controlled conditions allows for reliable quality assessment and comparison across different production batches or supplier sources.
Key Topics
Conditioning Atmospheres:
Specifies standard atmospheres (temperature and relative humidity) for conditioning, such as:- 23°C ± 1 / 50% RH ± 2% (preferred)
- 27°C ± 1 / 65% RH ± 2%
- 20°C ± 1 / 65% RH ± 2%
Equipment Requirements:
Calls for use of controlled-environment rooms equipped with automatic temperature and humidity regulators and continuous monitoring equipment, such as calibrated recording hygrometers.Conditioning Methods:
- Suspension of sacks during conditioning to ensure even air exposure.
- Omission of preconditioning to reduce potential errors, especially for specific construction types.
- Distinct minimum conditioning periods:
- 24 hours for sacks without barrier plies
- 7 days for sacks with barrier plies
Test Reporting:
Provides a checklist of information to be included in conditioning and test reports, such as sample details, atmospheric conditions, conditioning duration, standard references, detailed results, deviations, features observed, and test date.
Applications
Quality Control:
Enables manufacturers and testing laboratories to establish consistent baseline conditions for testing paper sacks, removing environmental variables that could affect test outcomes.Procurement and Supplier Qualification:
Ensures that buyers can objectively compare performance data for paper sacks from different suppliers, fostering a fair and transparent supply chain.Compliance and Certification:
Used as part of product certification processes to demonstrate adherence to international best practices in packaging material testing.Product Development:
Provides a standardized approach for research and development teams to evaluate and improve the performance of new paper sack designs or materials.Global Trade:
Harmonized conditioning and testing practices help remove technical barriers in international trade by aligning requirements across regions.
