Emballages - Sacs - Méthode d'échantillonnage de sacs vides pour essais (ISO 7023:1983)

La présente Norme internationale spécifie une méthode pour l'obtention d'un échantillon représentatif de sacs d'emballage vides pour essais. La présente Norme internationale est applicable dans le cas d'un échantillonnage destiné à établir la qualité moyenne d'une expédition limitée de sacs vides. La méthode ne convient pas à un échantillonnage pour un contrôle de production. La méthode s'applique à tous les types de sacs vides.  
NOTE -- Il faut noter que l'échantillon est seulement représentatif des sacs disponibles pour l'échantillonnage. Il faudra être très prudent dans l'extrapolation des résultats d'un tel échantillonnage à une expédition plus importante.

Overview

SIST EN 27023:1997, titled "Packaging - Sacks - Method of sampling empty sacks for testing", is a European standard adopted from ISO 7023:1983. Developed by CEN (European Committee for Standardization), this standard defines a systematic method to select random samples of empty sacks for quality testing. It ensures representative sampling of sacks from a consignment or lot to assess average quality, regardless of sack type. The method employs a two-stage random sampling procedure involving units and potentially subdivided elements to achieve reliable, unbiased test samples.

Key Topics

  • Scope and Purpose
    EN 27023 applies to all types of empty sacks and is primarily used to evaluate the average quality of sack consignments, not for direct production control.

  • Sampling Procedure

    • Two-Stage Sampling:
      1. Selection of a prescribed number of units (e.g., bundles, bales, pallet loads) from the total lot.
      2. Selection of sacks either directly from units or from elements within units, depending on the unit’s subdivision.
    • Random Selection: Every sack or subunit has an equal chance of selection to ensure representativeness.

  • Tables for Guidance
    EN 27023 provides tables to determine how many units and sacks should be sampled based on lot size, aligning with ISO 3951 sampling principles.

  • Definitions
    Clarifies terms such as ‘lot,’ ‘unit,’ ‘element,’ and ‘sample’ to standardize understanding and application.

  • Precautions and Marking
    Emphasizes careful handling of sacks during sampling to prevent changes in properties. Requires proper marking and documentation of selected sacks for traceability.

  • Re-sampling Rules
    Specifies procedures to follow if re-sampling is necessary due to accidents or other reasons, maintaining consistency with the initial sampling method.

  • Test Reporting
    Mandates detailed reports including sampling references, parties involved, sampling conditions, lot characteristics, and any deviations from the standard.

Applications

EN 27023 is vital for organizations looking to:

  • Quality Assurance in Packaging
    Utilize a standardized method to objectively evaluate the quality of empty sacks delivered or manufactured, helping to maintain packaging integrity.

  • Supplier and Vendor Compliance
    Perform random sampling on consignments to verify adherence to agreed specifications.

  • Inspection and Testing Labs
    Apply consistent sampling techniques to generate valid and reproducible test results that reflect lot quality.

  • Logistics and Warehousing
    Control and sample incoming sacks inventory before use in packaging operations, reducing risk of product damage.

  • Regulatory and Trade
    Facilitate fair trade and contractual compliance by using internationally recognized sampling protocols.

Related Standards

  • ISO 7023:1983
    The original international equivalent standard that EN 27023 is based on, outlining the fundamental sampling method for empty sacks.

  • ISO 3951
    Provides detailed sampling procedures and charts used to determine the number of sacks to sample for inspection by variables and percent defective rates.

  • ISO 106
    Describes paper and board sampling methods, complementing sack sampling in packaging quality control environments.

By adhering to EN 27023, stakeholders involved in the packaging supply chain can ensure rigorous control over sack quality through standardized, reproducible sampling practices. This supports overall packaging performance, reduces defects, and ensures customer satisfaction.

Foreword ISO (the International Organization for Standardization) is a worldwide federation of national Standards bodies (ISO member bodies). The work of developing International Standards is carried out through ISO technical committees. Every member body interested in a subject for which a technical committee has been authorized 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. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the ISO Council. International Standard ISO 7023 was developed by Technical Committee ISO/TC 122, Packaging, and was circulated to the member bodies in February 1982. lt has been approved by the member bodies of the following countries : Australia Germany, F.

INTERNATIONAL STANDARD ISO 7023-1983 (E) Packaging - Sacks - Method of sampling empty Sacks for testing 1 Scope and field of application This International Standard specifies a method of obtaining a representative Sample of empty Sacks for testing. This International Standard is applicable when sampling in Order to assess the average quality of a consignment of empty Sacks. The method is not suited to sampling for production control. The method applies to all types of empty Sacks. NOTE - It should be noted that the Sample is representative only of those Sacks available for sampling. Considerable caution should be ex- ercised when extrapolating the results from such sampling to a larger consignment. 2 References ISO 106, Paper and board - Sampling for testing. ISO 3951, Sampling procedures and Charts for inspection by variables for percen t defective. 3 Definitions For the purpose of this International Standard, the following definitions apply. 3.1 lot : The aggregate of Sacks which are of a Single kind with specified characteristics, on which a judgement is desired (usually as to compliance with specification) and which are available for sampling. NOTES 1 The number of Sacks comprising a lot may be indicated on the in- voice or agreed upon by the contracting Parties. 2 When the number of Sacks available for sampling is less than the lot size agreed or indicated on the invoice, the total number of Sacks available may be taken as a lot subject to the caution given in the note to clause 1. 3.2 unit : The unit may be in the form of a bundle, bale, pallet load, Container load, etc. One or more nominally identical units constitute a lot. 3.3 element : The element may be in the form of a b
