Overview

ISO 6451:1982 specifies a rapid method for checking fusion of polyvinyl chloride (PVC) coatings on plastics coated fabrics. Intended as a quick screening test for PVC-coated textiles, the method identifies whether a PVC coating has adequately fused to the substrate. It is not suitable for coatings made from aqueous PVC dispersions.

Key topics and requirements

• Scope: Rapid fusion-check test for PVC coatings on coated fabrics (excludes aqueous dispersion PVC coatings).
• Reagents and apparatus:
  • Acetone, analytical grade.
  • Glass vessel large enough to hold test assemblies (can be covered).
  • Glass rod, diameter 5 mm.
  • Metal clips to secure test pieces.
• Test pieces:
  • Normally three test pieces per coated face.
  • Typical dimensions depending on thickness: 20 mm × 40 mm or 20 mm × 70 mm.
  • Take samples from center and from positions at least 200 mm from the edges; use six pieces when coated on both sides (three per face).
• Procedure (summary):
  • Visually inspect PVC layer for existing cracks/holes and record.
  • Fold each test piece over the 5 mm glass rod with the coating outward and secure with a metal clip.
  • Immerse assemblies in acetone at standard laboratory temperature for 15 minutes.
  • Remove and visually examine the bent area for new cracks or holes. Disregard lacquer removal or superficial surface effects.
• Interpretation and reporting:
  • If fresh cracks or holes appear in the bent area, fusion is incomplete (fail).
  • Test report must include reference to ISO 6451:1982, product identification, test temperature, result (fusion complete/incomplete), any deviations, date, and test-piece length.

Applications and users

ISO 6451:1982 is a practical, low-cost screening method used for:

• Quality control in manufacturing of PVC-coated fabrics (awnings, tarpaulins, upholstery, technical textiles).
• Incoming inspection by procurement teams to confirm coating integrity.
• R&D and material evaluation to quickly compare fusion quality across formulations or processes.
• Conformity checks in independent testing laboratories and by compliance officers.

Typical users: quality assurance technicians, lab analysts, materials engineers, textile/coating manufacturers, and buyers specifying coated-fabric performance.

Related standards

• ISO 6451:1982 was prepared by ISO/TC 45 (Rubber and rubber products). Other ISO standards on coated fabrics, PVC testing, and physical/chemical test methods may be relevant; consult the ISO catalogue or national standards bodies for related or successor standards.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards institutes (ISO member bedies). The work of developing Interna-
tional Standards is carried out through ISO technical committees. Every member body
interested in a subject for which a technicai committee has been set up 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 6451 was developed by Technical Committee ISO/TC 45,
Rubber and rubber products, and was circulated to the member bodies in November
1980.

Avant-propos
L’ISO (Organisation internationale de normalisation) est une fédération mondiale
d’organismes nationaux de normalisation (comités membres de I’ISO). L’élaboration
des Normes internationales est confiée aux comités techniques de I’ISO. Chaque
comité membre intéressé par une étude a le droit de faire partie du comité technique
correspondant. Les organisations internationales, gouvernementales et non gouverne-
mentales, en liaison avec I’ISO, participent également aux travaux.
Les projets de Normes internationales adoptés par les comités techniques sont soumis
aux comités membres pour approbation, avant leur acceptation comme Normes inter-
nationales par le Conseil de I’ISO.
La Norme internationale ISO 6451 a été élaborée par le comité technique ISO/TC 45,
hastomères et produits à base d’élastomères, et a été soumise aux comités membres
en novembre 1980.
Les comités membres des pays suivants l’ont approuvée :
Afrique du Sud, Rép. d’ Égypte, Rép. arabe d’ Royaume-Uni
