BS EN ISO 12017:1996 is a standard related to plastics, specifically focusing on poly(methyl methacrylate) (PMMA) double- and triple-skin sheets. This standard provides test methods for evaluating the properties and performance of PMMA double- and triple-skin sheets. These sheets are often used in various applications, including glazing, signage, and protective barriers. Here's an overview of this standard:
The scope of BS EN ISO 12017:1996 is to establish test methods for assessing the properties and characteristics of PMMA double- and triple-skin sheets. These sheets are multi-layered structures made of poly(methyl methacrylate) and are commonly used in applications requiring transparency, impact resistance, and weatherability.
Purpose: The primary purpose of this standard is to provide a standardized set of test methods for evaluating the performance of PMMA double- and triple-skin sheets. These tests help determine the suitability of these sheets for specific applications and ensure they meet quality and safety standards.
Key Aspects Covered:
Test Specimens: Guidelines for preparing test specimens from PMMA double- and triple-skin sheets for subsequent testing.
Mechanical Properties: Test methods for assessing various mechanical properties, including tensile strength, flexural properties, and impact resistance. These properties are important for determining the material's structural integrity and its suitability for specific applications.
Thermal Properties: Procedures for evaluating thermal properties, such as heat deflection temperature and coefficient of linear thermal expansion. Understanding these properties is crucial for applications where temperature fluctuations are a concern.
Optical Properties: Test methods for assessing optical properties, including light transmission, haze, and color characteristics. These properties are particularly important for applications that require transparency and optical clarity.
Weatherability: Evaluation of the resistance of PMMA double- and triple-skin sheets to outdoor weathering and UV radiation, which can impact their long-term performance.
Chemical Resistance: Procedures for determining the chemical resistance of the material to various chemicals and solvents.
Flammability: Assessment of the flammability characteristics of PMMA double- and triple-skin sheets to ensure they meet safety standards.
Testing Conditions: Specifications for test conditions, including temperature, humidity, and other environmental factors, to ensure consistency and repeatability of test results.
Reporting: Guidelines for reporting the results of the tests, including the specific test methods used, units of measurement, and any relevant statistical information.
