Описание (английский):

ISO 1421:2016 specifies two methods for the determination of the tensile strength of fabrics coated with rubber or plastics. - Method 1 ? the strip test method, which is a method for the determination of tensile strength and elongation at break. - Method 2 ? the grab test method, which is a method for the determination of tensile strength only. The methods apply to test pieces in equilibrium with specific standard atmospheres for testing and to wet test pieces. Both methods require the use of a constant rate of extension (CRE) tensile-testing machine.

Overview

ISO 1421:2016 specifies standardized laboratory methods to determine the tensile strength and elongation at break of rubber‑ or plastics‑coated fabrics. It defines two test procedures - the strip test (Method 1) for tensile strength and elongation at break, and the grab test (Method 2) for tensile strength only. Both methods apply to conditioned test pieces and to wet test pieces, and both require a constant rate of extension (CRE) tensile‑testing machine.

Key Topics and Requirements

Test methods

Method 1 - Strip test: measures maximum force, elongation at maximum force and, if required, force and elongation at break.
Method 2 - Grab test: measures maximum force (tensile strength) only.

Apparatus

Use a CRE tensile‑testing machine capable of recording force and extension with specified accuracy (machine performance per ISO 7500‑1).
Force measurement error: ±1 %; jaw separation error: ±1 mm (as specified).
Jaw geometry: strip test jaws not less than specimen width (preferably ≥ 60 mm); grab test jaws include a 25 mm × 25 mm clamping area (±0.5 mm).
Optional extensometer for strain measurements; capstan or self‑locking jaws recommended when slippage or jaw breaks are a concern.

Specimen preparation and conditioning

Test pieces cut longitudinally and transversely; minimum sample counts specified (e.g., five per direction).
Conditioning in standard atmospheres referenced to ISO 2231:1989 (e.g., recommended exposure times: 16 h for one‑side coated, 24 h for both‑sides coated).
Procedures for testing wet specimens, including immersion and use of distilled/deionized water and surfactant.

Timing

Minimum time between manufacture and testing: 16 h; standard limits for comparability and product testing are specified.

Applications and Who Uses It

ISO 1421:2016 is used by:

Manufacturers of rubber‑ or plastics‑coated fabrics for quality control, batch verification and product development.

Third‑party testing laboratories and certification bodies to demonstrate compliance with client specifications.

Specifiers, procurement teams and regulatory bodies that require reproducible mechanical property data for safety, durability and material selection.

R&D teams assessing coating formulations, substrate compatibility and end‑use performance.

Practical benefits include consistent tensile data for design decisions, reliable comparison between materials and vendors, and defensible test reports for contractual and regulatory purposes.
