Overview

SIST EN 13676:2002 is a European Standard developed by CEN that specifies a precise procedure for detecting and estimating pinholes in polymer-coated paper and board intended for food contact. Pinholes-small openings in the polymer layer-can compromise the barrier properties of coated materials, potentially allowing contaminants to penetrate and affecting food safety. This standard applies universally to all types of polymer-coated paper and board, ensuring consistent quality control and compliance with food contact regulations.

Key Topics

  • Purpose: Detect and quantify pinholes in polymeric coatings on paper and board.
  • Scope: Applicable to all polymer-coated paper and board materials used in direct food contact.
  • Definitions:
    • Pinhole: Small hole or opening in the polymer layer sufficient to allow penetrant transfer.
  • Testing Principle:
    The coated sample is exposed on one side to a coloured ethanol-based solution for 5 minutes. Any pinholes allow the dye to penetrate, forming visible coloured spots that can be counted.
  • Reagents Required:
    • Ethanol (96% volume)
    • Dyestuff E131 Blue or Crossing Scarlet MOO
    • Colour solution (0.5% w/v dyestuff in ethanol)
  • Sampling:
    Follows EN ISO 186 for representative sampling, with at least five specimens tested without humidity conditioning unless otherwise specified.
  • Apparatus:
    General laboratory equipment and devices suitable for one-sided testing, such as those described in EN 20535 or ENV 1186-1.
  • Interpretation:
    Number of dye-stained spots (pinholes) per square decimetre is calculated and reported.
  • Reporting:
    Test reports must reference SIST EN 13676:2002 and include sample identification, testing conditions, area tested, results, and any deviations from the procedure.

Applications

SIST EN 13676:2002 is vital for manufacturers, quality control laboratories, and regulatory bodies involved with food packaging materials to:

  • Ensure barrier integrity: Quickly identify defective polymer coatings that could compromise food safety.
  • Support compliance: Meet European food contact material regulations by validating the suitability of coated paper and board.
  • Quality control: Standardize inspection procedures for pinholes during production or prior to shipment.
  • Risk mitigation: Prevent migration of contaminants through coating defects, protecting consumer health.
  • Test development: Facilitate reliable screening methods for food packaging migration testing protocols.

This method offers a straightforward, cost-effective approach to detect critical defects that are invisible to the naked eye but impactful on functional performance.

Related Standards

  • EN 20535: Determination of water absorptiveness in paper and board, relevant for apparatus setup.
  • ENV 1186-1: Guide on the selection of test conditions and methods for overall migration testing of plastics in contact with food.
  • CEN/TC 172: Technical committee responsible for standards relating to pulp, paper, and board.
