ISO 11752:2000/Amd 1:2006

Overview

ISO 11752:2000/Amd 1:2006 is an important amendment to the international standard focusing on flexible cellular polymeric materials, specifically moulded and extruded sponge or expanded cellular rubber products. This document outlines updated procedures for the compressibility testing of finished parts, ensuring improved accuracy and consistency in material performance evaluation. The amendment reflects advancements in test equipment specifications and calibration standards, enhancing the reliability of compression tests used in quality control.

Key Topics

• Scope of Materials: Covers flexible cellular polymeric materials including sponge and expanded cellular rubber products that are moulded or extruded.
• Compressibility Test Method: Specifies the test procedure to assess compressibility on finished products, crucial for applications requiring resilience and cushioning properties.
• Updated Normative References:
  • Replaces older standards such as ISO 471 with ISO 23529 for general test piece preparation and conditioning.
  • Updates specifications for test equipment, referencing ISO 5893:2002 and ISO 7500-1:2004, establishing classes for force and deflection measurement that enhance accuracy.
• Test Equipment Calibration: Emphasizes verification and calibration of testing machines according to ISO 7500-1:2004 to ensure test force measurement reliability.
• Measurement Tolerance Changes: Adjusts or removes previous error limits, reflecting the adoption of more precise equipment standards.

Applications

The ISO 11752:2000/Amd 1:2006 standard is vital for industries utilizing flexible cellular polymers where compressive properties impact product performance, including:

• Automotive and Transportation: Components like seals, gaskets, and vibration dampers require validated compressibility to ensure durability and safety.
• Footwear Manufacturing: Shoe soles and cushioning layers depend on reliable compression characteristics for comfort and longevity.
• Construction and Insulation: Sponge rubber used in sealing and insulation benefits from standardized compressibility data to meet performance criteria.
• Medical Devices: Pads and cushioning materials must meet strict compressibility parameters to ensure functionality.
• Consumer Goods: Products such as protective packaging utilize expanded cellular rubber needing consistent compression behavior.

Adherence to this updated standard enhances quality assurance processes, enabling manufacturers to deliver finished parts that meet defined compressibility criteria and perform predictably under load.

Related Standards

• ISO 23529 – Rubber: General procedures for preparing and conditioning test pieces for physical test methods, replacing ISO 471.
• ISO 5893:2002 – Rubber and plastics test equipment: Specification for tensile, flexural, and compression test machines, defining performance requirements for deflection measurement.
• ISO 7500-1:2004 – Metallic materials: Verification and calibration of force-measuring systems in tension/compression testing machines, ensuring test equipment accuracy.
• ISO 11752:2000 – Original standard covering compressibility test methods for flexible cellular polymeric materials before amendment.

These related standards collectively facilitate accurate, repeatable testing and support industries in maintaining international quality benchmarks for cellular rubber products.

By following the revised testing methodologies and calibration requirements set forth in ISO 11752:2000/Amd 1:2006, organizations involved in the production and application of flexible cellular rubber materials can assure customers of product performance while aligning with globally recognized quality standards.
