Emballages - Conditionnement pour essais - Partie 1: Sacs en papier (ISO/FDIS 6599-1:2026)

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

kSIST FprEN ISO 6599-1:2026 – Packaging - Conditioning for Testing - Part 1: Paper Sacks provides standardized procedures for conditioning intact, empty paper sacks before and during testing. Developed by SIST and aligned with ISO/FDIS 6599-1:2026, this international standard defines the atmospheric conditions and methodology required to ensure consistent and reliable test results for paper sack packaging.

Establishing temperature and humidity equilibrium is essential in packaging testing, as the physical properties of paper sacks are significantly influenced by environmental conditions. By standardizing the conditioning process, kSIST FprEN ISO 6599-1:2026 enables fair comparison and accurate performance assessment across the packaging industry.

Key Topics

• Conditioning Atmospheres: Specifies standard conditioning atmospheres (e.g., 23°C/50% RH, 27°C/65% RH, 20°C/65% RH) to ensure uniformity during testing.
• Equipment Requirements: Outlines specifications for climate-controlled rooms and measuring instrumentation, including the use of recording hygrometers and periodic calibration checks.
• Conditioning Procedures: Details minimum duration for conditioning-at least 24 hours for sacks without barrier plies, and at least 7 days for those with one or more barrier plies.
• Test Reporting: Describes mandatory elements for documentation, such as reference to the standard, conditions used, duration of conditioning, and any deviations or noteworthy observations.
• Definitions and Terminology: Incorporates terminology from ISO standards to ensure clarity regarding terms like "relative humidity" and "conditioning."
• Relevance of Moisture Content: Emphasizes the impact of moisture and temperature on paper sack performance during standardized packaging tests.

Applications

The standardized conditioning procedures outlined in kSIST FprEN ISO 6599-1:2026 have broad practical value in the packaging sector, including:

• Quality Control: Ensures that material property tests on paper sacks are conducted under repeatable conditions, supporting quality assurance in manufacturing processes.
• Product Development: Allows packaging engineers to accurately evaluate new paper sack designs or materials under defined environmental conditions.
• Regulatory Compliance: Assists organizations in meeting national and international regulatory requirements for packaging testing and certification.
• Supply Chain Consistency: Facilitates reliable, comparable test results across different laboratories and production sites, promoting fair competition and interoperability.
• Sustainability Initiatives: Supports environmentally sensitive product assessments by allowing consistent evaluation of biodegradable paper sacks.

By following the guidelines set by this standard, businesses and laboratories can ensure that the physical properties of paper sacks-such as strength, durability, and performance in real-world conditions-are assessed in a scientifically sound and consistent manner.

Related Standards

For comprehensive packaging testing and conditioning, the following standards are referenced and closely related:

• 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

Together, these international standards provide the foundation for effective packaging testing and ensure global harmonization in packaging quality assessment. By aligning with kSIST FprEN ISO 6599-1:2026, stakeholders across the packaging value chain can promote reliable and high-quality paper sack performance 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.
