EN ISO 2286-2:2016 PDF

Overview

EN ISO 2286-2:2016 specifies standardized laboratory methods for measuring the total mass per unit area, the mass per unit area of the coating, and the mass per unit area of the substrate of rubber- or plastics-coated fabrics. Part of the ISO 2286 series on roll characteristics, this document defines sampling, test-piece preparation, conditioning, measurement and calculation procedures used by manufacturers, test laboratories and specifiers to quantify key material properties.

Key topics and technical requirements

• Scope: Measurement methods for coated textiles to determine total fabric mass and to separate coating and substrate mass contributions.
• Sampling & test pieces: Cut five test pieces spaced diagonally across the usable width (exclude 50 mm from edges and avoid within 1 m of roll ends). A cutter capable of producing a test area of 100 cm2 ± 1 cm2 is recommended.
• Apparatus: Precision balance readable to 1 mg or better. Controlled drying atmosphere capability (relative humidity ≤ 10 % at 65 °C ± 5 °C) if drying is required.
• Conditioning: After any drying, condition specimens per ISO 2231:1989 (method “1”) before mass determination.
• Calculation: Convert mass (g) and area (cm2) to mass per unit area (g/m2) using M = (m × 10 000) / A and report the mean of five determinations to the nearest 1 g/m2.
• Coating removal: Annex A provides specific coating‑removal methods for certain coating compositions so that substrate mass can be determined accurately.
• Reporting: Test report items are defined, including specimen details, conditioning, measured masses and calculated results.

Applications and users

EN ISO 2286-2:2016 is used for:

• Quality control in production of coated fabrics (PVC, rubber-coated textiles).
• Incoming material inspection by manufacturers of tarpaulins, conveyor belts, inflatable products, awnings, and technical textiles.
• Product specification and procurement - to verify supplier claims on areal mass and coating weight.
• Failure analysis and R&D - to correlate coating/substrate mass with mechanical performance, durability and coating adhesion. Primary users: textile and rubber product manufacturers, independent testing laboratories, product engineers, standards and compliance teams.
