Plastics-coated fabrics for upholstery - Part 1: Specification for PVC-coated knitted fabrics

This document specifies requirements for coated fabrics for upholstered furniture for interior use, obtained by applying to one side of a weft-knitted base cloth a substantially continuous coating of a suitably plasticized polymer of vinyl chloride, or a copolymer the major constituent of which is vinyl chloride. Such coatings are known as poly(vinyl chloride) (PVC) coatings. This document covers fabrics coated with solid PVC. It also covers two grades with coatings consisting of a layer of expanded PVC.

Overview

ISO 7617-1:2024 - "Plastics-coated fabrics for upholstery - Part 1: Specification for PVC‑coated knitted fabrics" is the fourth edition (2024) international standard that defines requirements and test procedures for PVC-coated weft‑knitted base fabrics intended for interior upholstered furniture. It covers fabrics with solid PVC coatings and two grades that use a layer of expanded PVC. The standard sets out sampling, preliminary inspection, testing and compliance rules to ensure consistent quality, durability and safety of PVC‑coated upholstery fabrics.

Key Topics

• Scope and applicability: PVC‑coated knitted fabrics for interior upholstery; solid and expanded PVC coating grades.
• Sampling and traceability: Guidance on sampling by manufacturing batch or random sampling where batch identity is not available.
• Preliminary inspection:
  • Visual inspection for uniformity, flaws and cracks; minimum distance of 5 cm for cutting specimens from visible flaws.
  • Pinhole examination at ×6 magnification with a mean pinhole density limit (see standard).
  • Fusion check to verify coating adhesion to the knitted base (per ISO 6451).
  • Bend test - coated face outward 180° without noticeable whitening (whitening must be reported).
• Dimensions and roll characteristics: Usable width, roll length and thickness requirements (referenced to ISO 2286 series).
• Physical and mechanical requirements:
  • Mass of coating per unit area, tensile and bursting strength, tear resistance, abrasion resistance, flex resistance and surface properties (tests referenced to ISO 1421, ISO 3303-2, ISO 4674-1, ISO 5470-2, ISO 32100).
  • Properties after accelerated ageing (ISO 1419) and fire behaviour requirements.
• Marking and test reporting: Mandatory information for product marking and structured test reports. Annexes specify specimen selection and resistance-to-print-wear methods.

Applications

ISO 7617-1:2024 is used for:

• Specifying and verifying the quality of PVC‑coated upholstery fabrics for sofas, chairs, automotive interiors and contract seating.
• Quality control and incoming inspection by textile mills, converters and fabric suppliers.
• Product procurement and acceptance criteria for furniture manufacturers and contract specifiers.
• Laboratory testing and certification bodies performing mechanical, ageing, abrasion and colour‑fastness tests.
• R&D and formulation control for PVC coating manufacturers seeking compliance and market acceptance.

Related Standards

Key normative references and related tests include:

• ISO 6451 (fusion check)
• ISO 2286‑1/2/3 (roll characteristics)
• ISO 1421 (tensile strength)
• ISO 4674‑1 (tear resistance)
• ISO 5470‑2 (abrasion - Martindale)
• ISO 1419 (accelerated ageing)
• ISO 32100 (flex resistance)
• EN 15977 (related mechanical property methods)

For suppliers, laboratories and specifiers, ISO 7617-1:2024 provides a practical framework to ensure durability, appearance and safety of PVC‑coated knitted upholstery fabrics.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO 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,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at

4 Sampling
If individual rolls can be identified with manufacturing batches, at least one sample shall be taken from each
batch in the consignment. Each sample shall be regarded as being representative of its source and suitable
measures shall be taken to preserve the identity between the samples and batch numbers.
If individual rolls cannot be identified in this way, the number of samples to be regarded as being
representative of the bulk shall be fixed by agreement between the interested parties. Such samples shall be
drawn at random.
5 Testing and compliance
Samples shall first be subjected to the preliminary examination described in 6.1, which enables grossly
defective coated fabrics to be rejected immediately. If the samples satisfy this examination, testing shall
continue as follows:
— Tests shall be carried out on a set of test specimens selected from each sample in accordance with
Annex A. If testing shows that the test specimens meet the requirements of Tables 1 to 4, the bulk of the
coated fabric represented by the sample shall be deemed to meet the requirements of this document.
— If any of the set of specimens tested do not meet any of the appropriate requirements given in Tables 1 to
4, the tests can be repeated based on an agreement between the interested parties. For this purpose,
two further samples shall be taken from the same source as the original sample, and test specimens
shall be taken from each sample so that duplicate tests can be conducted. If all the re-test results meet
the appropriate requirements of Tables 1 to 4, then the bulk represented by the samples from which
the specimens for re-testing were taken, together with the original samples, shall be deemed to meet
the requirements of this document. If any of the results of the re-tests do not meet the appropriate
requirements of Tables 1 to 4, then the bulk represented by those samples shall be deemed not to meet
the requirements of this document.

6 Requirements
6.1 Preliminary inspection
6.1.1 General
A preliminary inspection shall be carried out as specified in 6.1.2 and 6.1.3, before conducting a detailed
examination and expensive tests, in order to ensure that the samples do not exhibit easily detectable
unacceptable faults. If such faults are detected, the inspection shall be stopped and the sample shall be
considered as not meeting the requirements
