BS EN ISO 11963:2019

What is ISO 11963 about?

ISO 11963 provides dimensions, characteristics and types of plastic polycarbonate sheets.

ISO 11963 specifies the requirements for solid, flat extruded sheets of polycarbonate (PC) for general applications. It applies specifically to sheets made of poly(p,p′-isopropylarene-diphenyl carbonate). The sheets can be coloured or colourless, and they can be transparent, translucent, or opaque. The sheets can also be those that have a special weather-protective layer on one or both surfaces.

ISO 11963 applies only to thicknesses equal to or greater than 1,5 mm.

Who is ISO 11963 for?

ISO 11963 on polycarbonate sheets is relevant to:

• Manufacturers of Polycarbonate sheets
• Chemical Engineers
• Researchers and scientists
• Distributors and suppliers of polycarbonate sheets

Why should you use ISO 11963?

Polycarbonate is a thermoplastic material that comes in transparent sheets. It is strong and absorbs little moisture, so it is highly resistant to impact and water damage.

ISO 11963 specifies all requirements of polycarbonate plastic such as masking, appearance, colour, and dimensions, and measures thickness deviations in particular shapes.

Test methods provided by ISO 11963 are designed to assess the durability and quality of polycarbonate samples, and information related to the testing can be provided to the testing operations.

Overall, ISO 11963 is a comprehensive guide to processing and manufacturing polycarbonate plastic, so users will gain a comprehensive understanding of the process and the end product will be safer, more durable and more environmentally friendly.

What’s changed since the last update?

BS EN ISO 11963:2019 supersedes BS EN ISO 11963:2012, which is withdrawn and includes:

• Relative humidity rule (50 ± 10) % was deleted from 5.4.1. Dimension change by the moisture absorption is very small, and the polycarbonate materials do not need to state adjustment of relative humidity in the dimensional measurement.
• Relative humidity rule was changed from (65 ± 5) % to (50 ± 10) % in 6.7.2. Polycarbonate materials are not humidity-sensitive materials in weathering.
