Overview

EN 26591-2:1992 (identical with ISO 6591-2:1985) defines the description and method of measurement for empty sacks made from thermoplastic flexible film. The standard specifies how to describe plastic sacks by type and dimensional designation, the measurement equipment and procedure, sampling requirements, calculation and reporting of results. It is intended for use with plastic sacks as referenced in ISO 6590-2.

Key topics and technical requirements

  • Scope and purpose: Method for measuring and expressing dimensions of empty thermoplastic flexible-film sacks (plastic sacks).
  • Dimensional designation: Sacks are described by successive indication of type and dimensions using up to eight figures (for example b/e/a/c or b/a/v/f/i depending on sack type). Common dimension symbols:
    • b = width, a = length, e = gusset width, c = bottom width
    • v = valve width, f = valve length, i = valve sleeve length, n = heat-seal distance
  • Types covered: Open-mouth heat-sealed, open-mouth pasted, gusseted, valved (heat-sealed or pasted) and hexagonal/rectangular bottoms - with standard diagrammatic designations for each.
  • Valve position: Defined relative to front-side print (top/bottom, left/right) to standardize valve location descriptions.
  • Measurement equipment: Simple ruler or instrument graduated in millimetres, capable of 1 mm accuracy.
  • Sampling: Follow ISO 7023; take at least 10 sample sacks for measurement.
  • Procedure: Lay sack flat, smooth wrinkles, measure specified dimensions at indicated points, measure at least 10 sacks to 1 mm accuracy.
  • Calculation and expression: Report the arithmetic mean of determinations, expressed in millimetres to the nearest millimetre.
  • Test report: Must include sample identification, reference to this standard, results (nearest mm), any unusual observations, and any optional operations or influences that may have affected results.

Applications and who uses it

  • Packaging manufacturers and converters for specifying and verifying sack dimensions during production.
  • Quality control and testing laboratories performing dimensional checks and issuing test reports.
  • Procurement and specification writers who need unambiguous dimensional designations for purchasing and tender documents.
  • Standards bodies and regulatory authorities that reference consistent measurement procedures for trade and compliance.
  • Designers and engineers developing packaging for bulk and industrial goods where valve location and sack geometry affect filling and handling.

Foreword IS0 (the international Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 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, govern- mental 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 IS0 Council. They are approved in accordance with IS0 procedures requiring at least 75 % approval by the member bodies voting. International Standard IS0 6591/2 was prepared by Technical Committee ISO/TC 122, Packaging. Users should note that all International Standards undergo revision from time to time and that any reference made herein to any other International Standard implies its latest edition, unless otherwise stated. @ International Organization for Standardization, 1985 Q Printed in Switzerland SIST EN 26591-2:1999
