BS EN ISO 11833-1:2019

What is ISO 11833-1 about? 

ISO 11833-1 is the first part of the multi-series European standard and provides dimensions, characteristics and types of plastic polycarbonate sheets  

ISO 11833-1 specifies the requirements for flat extruded sheets and pressed sheets of unplasticized poly(vinyl chloride) (PVC-U) and the test methods to be used to measure the required values. 

ISO 11833-1 applies only to sheets of thickness, not less than 1,0 mm. 

Note: ISO 11833-1 does not cover biaxially stretched PVC-U sheets. 

Who is ISO 11833-1 for? 

ISO 11833-1 on Unplasticized poly(vinyl chloride) sheets is relevant to: 

• Manufacturers of Unplasticized poly(vinyl chloride) sheets 
• Chemical Engineers 
• Researchers and scientists 
• Distributors and suppliers of polycarbonate sheets  

Why should you use ISO 11833-1? 

PVC is a common, strong but lightweight plastic used in construction. It is made softer and more flexible by the addition of plasticizers. 

ISO 11833-1 specifies all requirements of PVC-U such as masking, appearance, colour, and dimensions, and measures thickness deviations in particular shapes. 

Test methods provided by ISO 11833-1 are designed to assess the durability and quality of PVC-U samples, and information related to the testing can be provided to the testing operations. 

Overall, ISO 11833-1 is a comprehensive guide to processing and manufacturing PVC-U, 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BS EN ISO 11833-1:2019 supersedes BS EN ISO 11833-1:2012, which is withdrawn and includes: 

• The title has been editorially revised to read "Plastics — Unplasticized poly(vinyl chloride) sheets — Part 1: Types, dimensions and characteristics for sheets of thickness not less than 1 mm" 
• The "colour" requirements (former 5.3) have been incorporated with the "appearance" requirements in 6.2 (former 5.2) 
• The requirements for measurement at any other temperature (t °C) than 23 °Chas been added to 7.3.1 (former 6.3.1) 
• The method of handling the results of 7.4.1, 7.4.2 and 7.4.3 (former 6.4.1 to 6.4.3) have been added 
• “Testing of sheets with a thickness between 1,0 mm and <1,5 mm shall be subject between the interested parties” has been added in 7.5.1 (former 6.5.1); 
• A new Table 7 "Frequency and measurement positions of appearance tests and dimensional measurements" has been added and the subsequent tables have been renumbered.
