This standard specifies the methods for conducting tests on linoleum sheets and tiles to evaluate their physical properties and performance characteristics. It details procedures for checking dimensions, flexibility, indentation resistance, water absorption, and color fastness, serving as a basis for quality control and compliance.
Methods of tests for linoleum sheets and tiles
Quick Reference Values
Standard testing atmosphere temperature27 ± 2 °C
Standard testing atmosphere relative humidity65 ± 5 percent
Flexibility test mandrel diameter (for 2.00 mm thick)20 mm
Indentation test initial load9.8 N
Indentation test total load147 N
Water absorption test sample dimensions50 x 50 mm
Key Formulas
Water Absorption (%) = [(m2 - m1) / m1] x 100 — Where m1 is mass before immersion and m2 is mass after immersion.
Practical Notes
This standard only defines the test methods. The acceptable limits and performance requirements for linoleum are specified in the material specification standard, IS 653.
Strict adherence to sample conditioning as per IS 196 (27±2°C, 65±5% RH) is critical before testing to ensure result accuracy and comparability.
The indentation test (Clause 5) is crucial for assessing the flooring's ability to recover from pressure from furniture legs or other point loads.
