Full title and description

ISO 4675:2017 — Rubber- or plastics-coated fabrics — Low-temperature bend test. This International Standard specifies a laboratory method to determine the ability of fabrics coated with rubber or plastics to resist the effect of low temperature when subjected to bending after specified periods of exposure.

Abstract

ISO 4675:2017 defines a standardized low‑temperature bend test for rubber‑ or plastics‑coated fabrics. The method covers specimen preparation, apparatus (bending jig and low‑temperature chamber), conditioning, exposure at defined temperatures, the bending procedure and criteria for assessment of coating damage (cracks: depth, number and length). The procedure is intended for coated textile materials within a defined thickness range; results are intended for comparison and specification but are not a universal predictor of in‑service performance because application conditions vary.

Scope

Specifies a method for determining the ability of rubber‑ or plastics‑coated fabrics to withstand bending at low temperatures after defined exposure periods. The standard applies principally to coated fabrics with a coating/substrate thickness in the range 0.10 mm to 2.20 mm; for materials outside this thickness range the standard notes necessary modifications to the test arrangement. The procedure provides comparative data for specification and quality control but does not claim a universal relationship to every in‑service condition.

Key topics and requirements

• Definition of test principle: exposure at specified low temperature followed by a fixed bending procedure.
• Apparatus requirements: low‑temperature chamber, bending jig (dimensions and fixtures) and measurement tools.
• Specimen preparation and size, and recommended time interval between manufacture and test.
• Conditioning and environmental atmosphere requirements prior to testing.
• Specified temperature(s) and exposure durations; procedures for thicker materials requiring modified equipment.
• Assessment criteria for coating damage: depth of crack, number of cracks and length of cracks; pass/fail and reporting conventions.
• Test report content: identification, test conditions, results and any deviations from the method.
• Limitation statement: result interpretation should consider application‑specific conditions—no automatic correlation with service performance.

Typical use and users

Used by coated‑fabric manufacturers, quality control and testing laboratories, product designers and R&D teams, procurement/specification writers and conformity assessors who need a repeatable method to assess low‑temperature flexibility and cracking behavior of rubber‑ or plastics‑coated textiles. It is commonly used when materials are intended for low‑temperature service or to compare formulations and production batches.

Related standards

ISO 4675:2017 replaces ISO 4675:1990. Related and complementary standards include national or international low‑temperature bend/impact test methods (for example ASTM D2136 in some markets), and other ISO test standards for coated fabrics such as ISO 2231 (standard atmospheres for conditioning and testing), ISO 2286‑3 (thickness measurement methods), ISO 4674 (tear resistance methods), ISO 2411 (coating adhesion) and ISO 1421 (tensile testing). ISO 4646 (low‑temperature impact test) and other coated‑fabric durability tests are also relevant when assessing cold performance under different mechanical actions.

FAQ

Q: What is this standard?

A: ISO 4675:2017 is an International Standard that specifies a laboratory method — the low‑temperature bend test — to assess how rubber‑ or plastics‑coated fabrics respond to bending at low temperatures.

Q: What does it cover?

A: It covers specimen preparation, required apparatus, conditioning, exposure at specified low temperatures, the bending procedure, criteria for assessing coating damage (depth, number and length of cracks) and the required elements of the test report. It is intended for coated fabrics within a nominal thickness range of 0.10 mm to 2.20 mm, with guidance for thicker materials.

Q: Who typically uses it?

A: Manufacturers of coated fabrics, independent testing laboratories, R&D and product development teams, quality assurance personnel, spec writers and buyers who need a standardized, repeatable method to compare low‑temperature flexibility and cracking behavior.

Q: Is it current or superseded?

A: ISO 4675:2017 is the current published version (3rd edition) and replaces ISO 4675:1990. Users should confirm they are using the 2017 edition when specifying or performing the test.

Q: Is it part of a series?

A: ISO 4675:2017 is part of the family of ISO test methods and standards covering rubber‑ or plastics‑coated fabrics developed by ISO technical committees (ISO/TC 45 and its subcommittees). It is commonly used alongside other ISO and national standards addressing conditioning, thickness measurement, tensile properties, tear and abrasion resistance, and low‑temperature impact testing.
