ISO 1420 Rubber or plastics coated fabrics Resistance to penetration by water
The ISO 1420 standard is a critical protocol used in the textile testing sector for evaluating the resistance of rubber or plastic-coated fabrics to the penetration of water. This test is particularly relevant where waterproofing and durability are paramount, such as in automotive upholstery, industrial covers, and marine applications.
The primary objective of this test is to determine how effectively a fabric can prevent water from penetrating its surface under controlled conditions. The standard defines the methods for testing the resistance by applying a specific volume of water over the specimen and measuring the amount that penetrates through it after a specified period. This helps manufacturers ensure their products meet the required standards in terms of waterproof performance.
The test setup typically involves placing a known weight or volume of water on top of the coated fabric sample, which is clamped into position between two plates. The water is allowed to rest for a set duration before the amount that has passed through the material is measured and compared against the initial volume. Any leakage can be quantified and reported in terms of milliliters per square meter (ml/m²).
Proper specimen preparation is crucial for accurate testing results. Samples should be cut to standard dimensions, dried thoroughly, and conditioned according to ISO 12047-2 to ensure consistency with other laboratory conditions. This ensures that the test accurately reflects real-world performance rather than being influenced by environmental factors.
The instrumentation used in this test includes a water supply system capable of delivering the specified volume of water at room temperature, a stopwatch for timing the exposure period, and a scale or measuring device to quantify the amount of water that has penetrated through the fabric. The test results are reported in terms of milliliters per square meter (ml/m²), providing a direct measure of the fabric's resistance to water penetration.
This testing method is widely used across industries, particularly where waterproofing and durability are essential. For instance, automotive manufacturers rely on this standard to ensure that seats and upholstery remain dry in various weather conditions. Similarly, in industrial settings, rubber-coated fabrics must withstand harsh environmental conditions without allowing water penetration.
Compliance with ISO 1420 is often a regulatory requirement for certain products or applications where waterproofing standards are mandatory. This ensures that the end users of these materials can rely on their durability and performance over extended periods.
