Overview
ISO 2286-1:2016 specifies standardized methods for determining the length, usable width and net mass of a roll of rubber‑ or plastics‑coated fabrics. It defines the required apparatus, measurement procedures and reporting elements used for consistent roll characterization in production, inspection and contractual verification.
Key topics and technical requirements
- Scope: Measurement procedures apply to rolls of rubber‑ or plastics‑coated fabrics and form Part 1 of the ISO 2286 series.
- Apparatus:
- Measuring surface: flat, horizontal, ≥ 5 m long and at least as wide as the roll; longitudinal edges marked in 1 m lengths with at least one section marked at 1 cm intervals.
- Measuring scale: longer than fabric width, graduated in millimetres.
- Balance: accurate to the nearest 100 g.
- Length determination:
- Trim roll ends to be perpendicular to the roll axis (minimum trimming).
- Unroll without introducing tension, mark edges at fixed divisions, and measure sequential lengths along the measuring surface.
- Final length measured to the nearest 100 mm, unless otherwise agreed. The method is the referee method in disputes.
- Alternative mechanical, electromechanical or photoelectric measuring equipment may be used but can be unsuitable for extensible substrates (e.g., knitted).
- Usable width:
- Measure while unrolled and free of tension at 10 m intervals using the measuring scale.
- Record to the nearest 5 mm; for rolls
