Packaging - Drop test - Part 1: Paper sacks (ISO 7965-1:2024)

This document specifies a method of vertical impact testing on a filled paper sack by dropping. It is performed either as a single test to investigate the effects of vertical impact or as part of a sequence of tests designed to measure the ability of a sack to withstand a distribution system that includes a vertical impact hazard.
This document specifies the testing procedure and how the results of tests are presented. It is based on ISO 2248 but is specifically related to paper sacks.

Packmittel - Stoßprüfung im freien Fall - Teil 1: Papiersäcke (ISO 7965‑1:2024)

Dieses Dokument legt ein Verfahren zur vertikalen Stoßprüfung im freien Fall an befüllten Papiersäcken fest. Diese Prüfung wird entweder als Einzelprüfung durchgeführt, um die Einflüsse eines vertikalen Stoßes nach freiem Fall zu untersuchen, oder als Teil einer Prüffolge zur Ermittlung der Widerstandsfähigkeit eines Sacks im Rahmen eines Verteilungssystems, das eine vertikale Stoßbeanspruchung einschließt.
Dieses Dokument legt das Prüfverfahren fest und wie die Prüfergebnisse dargestellt werden. Seine Grundlage ist ISO 2248, jedoch besonders auf Papiersäcke bezogen.

Emballages - Essai de chute - Partie 1: Sacs en papier (ISO 7965-1:2024)

Le présent document spécifie une méthode d’essai de résistance au choc vertical de sacs en papier pleins lâchés en chute libre. Il s’agit d’essai isolé destiné à étudier les effets du choc vertical ou qui fait partie d’une série d’essais destinés à mesurer la capacité d’un sac à résister aux conditions d’un système de distribution comprenant un risque de choc vertical.
Le présent document spécifie le mode opératoire d’essai et la façon dont les résultats des essais sont présentés. Il est basé sur l’ISO 2248, mais a spécifiquement trait aux sacs en papier.

Embalaža - Preskus s prostim padom - 1. del: Papirnate vreče (ISO 7965-1:2024)

Ta dokument določa metodo za preskušanje napolnjene papirnate vreče ob navpičnem udarcu s prostim padom. Izvaja se kot samostojni preskus za raziskovanje učinkov navpičnega udarca ali kot del zaporednih preskusov za merjenje zmožnosti vreče glede prenašanja distribucijskega sistema, ki vključuje nevarnost navpičnega udarca.
Ta dokument določa preskusni postopek in način predstavitve rezultatov preskusov. Temelji na standardu ISO 2248, vendar se posebej navezuje na papirnate vreče.

Overview - EN ISO 7965-1:2024 (Packaging - Drop test - Part 1: Paper sacks)

EN ISO 7965-1:2024 / ISO 7965-1:2024 specifies a method for vertical impact testing of filled paper sacks by dropping. The standard is intended to assess how a paper sack responds to a vertical impact - either as a single investigation or as part of a sequence that simulates a distribution system including vertical impact hazards. It defines the test principle, required apparatus, sampling/conditioning, test procedures, methods for presenting results, and the content of the test report.

Key topics and technical requirements

• Scope: Tests apply specifically to filled paper sacks to evaluate resistance to vertical impacts during distribution.
• Principle: A filled sack is released from a predetermined height to strike a rigid, horizontal impact surface; drop height and package orientation are set in advance.
• Apparatus essentials (Clause 5):
  • Means to set and ensure correct drop height
  • Lifting arrangement that does not damage the sack
  • Platform and release mechanism ensuring unobstructed fall
  • Impact surface: horizontal, flat and rigid
• Sampling and conditioning:
  • Sampling for average quality follows ISO 7023
  • Paper sacks are conditioned for testing as described in ISO 6599-1 due to paper’s hygroscopic nature (Clause 7)
• Test procedures (Clause 8–9):
  • Filling and placement rules before dropping
  • Methods include progressive drop height and constant drop height
  • Tests may be performed as flat or butt impacts (side constant-height test excluded for constant method)
  • Reporting of sack breakage and other outcomes
• Test report: Clause 10 lists required information to present results consistently.

Applications and who uses this standard

• Packaging designers and material engineers validating paper sack strength and design.
• Quality control and testing laboratories conducting routine drop testing and supplier acceptance tests.
• Logistics, warehousing and distribution planners simulating handling impacts in supply chains.
• Manufacturers and purchasers specifying performance criteria for sacks in supplier contracts.
• Regulatory and compliance teams ensuring packaging meets recognized test methods.

Related standards

• ISO 2248 (basis for the method)
• ISO 6590-1 (sacks vocabulary and types)
• ISO 6599-1 (conditioning for testing - paper sacks)
• ISO 7023 (sampling empty sacks)

This standard helps ensure consistent, repeatable drop test results for paper sacks, supporting risk reduction in handling and distribution and enabling clear technical specifications for packaging performance.
