BS EN ISO 7823-1:1996 is a European Standard that specifies the types, dimensions, and characteristics of cast poly(methyl methacrylate) sheets. Poly(methyl methacrylate), commonly known as PMMA or acrylic, is a versatile thermoplastic material used in various applications, including signage, displays, lighting, and glazing. This standard helps establish specifications for cast PMMA sheets, ensuring their quality and consistency.
Here are some key points covered by BS EN ISO 7823-1:1996:
The standard defines the scope, which is specific to cast poly(methyl methacrylate) sheets. It does not cover other forms or processing methods of PMMA.
Types: It classifies cast PMMA sheets into different types based on their characteristics, such as optical properties, color, and surface finish.
Dimensions: The standard specifies the dimensions of cast PMMA sheets, including thickness, width, and length. These dimensions help ensure uniformity in the size of sheets produced.
Characteristics: BS EN ISO 7823-1:1996 provides information on various characteristics of cast PMMA sheets, which may include aspects like transparency, color, surface quality, and flatness.
Tolerances: The standard outlines tolerances for dimensions and characteristics to ensure that the manufactured sheets meet specified requirements.
Marking and Labeling: It provides guidelines for marking and labeling cast PMMA sheets to indicate compliance with the standard and to provide necessary information to users.
Sampling and Testing: The standard may specify sampling and testing procedures to verify that the sheets meet the defined characteristics and quality standards.
Manufacturers and users of cast PMMA sheets can refer to BS EN ISO 7823-1:1996 to ensure that the sheets they produce or use conform to established standards. This helps maintain consistency in the quality of PMMA sheets and ensures their suitability for various applications.
