SIST EN ISO 6591-1:2026

Overview

SIST EN ISO 6591-1:2026 is an international standard focused on the packaging industry, specifically for empty paper sacks. Developed in collaboration with ISO and CEN, this standard outlines the precise dimensions and the method of measurement for empty paper sacks. The aim is to support consistency, quality control, and reliable communication across manufacturers, suppliers, and users in the packaging sector. The 2026 edition replaces the previous standard (SIST EN 26591-1:1998), reflecting updates for improved clarity and relevance to modern industrial needs.

Key Topics

• Scope and Definitions: The standard clearly defines the dimensions of empty paper sacks, including length, width, bottom width, gusset width, valve length and position, and other relevant measurements. Specific terms are aligned with established packaging vocabularies.
• Measurement Methods: Detailed methods are provided for conditioning, measuring, and recording sack dimensions. All measurements are performed to a precision of 1 millimetre using calibrated tools.
• Types of Paper Sacks: The document covers a variety of empty paper sacks-including open mouth sewn sacks, pasted sacks, gusseted sacks, and sacks with valves. Guidance is given for measuring each sack type according to its structure.
• Sampling Procedures: Recommendations ensure that samples are representative of the whole batch, following best practices for testing uniformity and compliance.
• Reporting Requirements: Results must be clearly documented, including full identification of samples, conditioning conditions, measured dimensions, and any deviations or observations.
• Up-to-date References: The standard references related ISO documents for vocabulary, conditioning, and sampling to ensure compatibility and coherence across the packaging industry.

Applications

SIST EN ISO 6591-1:2026 delivers practical value across various applications in the paper packaging sector:

• Quality Control: Standardized measurement procedures help manufacturers monitor product uniformity and quality across different production batches.
• Procurement & Supply Chain: Provides a reliable basis for product specification and acceptance between suppliers and purchasers of empty paper sacks.
• Regulatory Compliance: Ensures packaging meets national and international legal and safety requirements, reducing the risk of disputes or misunderstandings.
• Design and Development: Supports research and development efforts by establishing precise benchmarks for sack design and dimensioning.
• Testing and Certification: Enables independent testing laboratories to deliver consistent, internationally recognized certifications to paper sack producers.

Paper sacks are widely used in industries such as food, chemicals, construction materials, and general goods. Adopting this standard enhances operational efficiency, reduces waste, and reinforces supply chain confidence.
