BS EN ISO 17855-2:2016

What is ISO 17855-2 - PE moulding and extrusion about?  

Polyethylene (PE) is a preferred material due to its durability and dynamic applications. This part of ISO 17855 specifies the methods of preparation of test specimens and the test methods to be used in determining the properties of PE moulding and extrusion materials. Requirements for handling test material and for conditioning both the test material before moulding and the specimens before testing are given. Properties and test methods that are suitable and necessary to characterize PE moulding and extrusion materials are listed. The properties have been selected from the general test methods in ISO 10350-1. Other test methods in wide use for or of particular significance to these moulding and extrusion materials are also included in this part of ISO 17855, as are the designatory properties specified in ISO 17855-1.  

To obtain reproducible and comparable test results, it is necessary to use the methods of preparation and conditioning, the specimen dimensions and the test procedures specified herein. Values determined will not necessarily be identical to those obtained using specimens of different dimensions or prepared using different procedures.

Who is ISO 17855-2 - PE moulding and extrusion for? 

ISO 17855-2  on PE moulding and extrusion is useful for: 

• Manufacturers of injection moulded products 
• Manufacturers of plastics and thermoplastics products 
• Manufacturers of automotive parts, electronic components 
• Manufacturers of products where PE components are used 
• The pharmaceutical and medical Industry 
• Product development teams 
• Quality control teams 

Why should you use ISO 17855-2 - PE moulding and extrusion?  

PE is available in clarity ranging from transparent to opaque, in an unlimited number of colour possibilities and applications for this versatile material include housewares, toys, food containers and closures, and automotive parts. ISO 17855-2 discusses the preparation of test specimens and the determination of properties so that you can decide on the uses of the material accordingly. The section on the preparation of test specimens guides you through the treatment of the material before moulding, injection moulding and compression moulding. 

The atmosphere for conditioning and testing of specimens has been discussed in detail in ISO 17855-2. Using ISO 17855-2 you would be able to prepare test specimens and determine properties of PE moulding and extrusion materials so that you can provide your customers with suitable products.
