BS EN ISO 21302-2:2019

What is ISO 21302-2 - Determination of properties PB-1 about?  

ISO 21302-2 is the second part of the multi-series ISO 21302. ISO 21302-2 specifies the methods of preparation of test specimens, and the test methods to be used in determining the properties of polybutene-1 (PB-1) moulding, and extrusion materials. Requirements for handling test material, and for conditioning both the test material before moulding, and the specimens before testing are specified in ISO 21302-2. 

Who is ISO 21302-2 - Determination of properties PB-1 for? 

ISO 21302-2 on the preparation of test specimens, and determination of properties PB-1 is useful for: 

• Polybutene-1 (PB-1) manufacturer 
• Polybutene-1 (PB-1) testing laboratories 
• Industrial parts 
• Medical devices 
• Electrical/electronics 
• Chemical processing 
• Automotive under-hood applications 

Why should you use ISO 21302-2 - Determination of properties PB-1?  

ISO 21302-2 provides you with methods for the preparation of test specimens, and determines the properties of PB-1 as to obtain reproducible, and comparable test results.  

ISO 21302-2 guidelines ensures reliable procedures, and conditions for the preparation of test specimens, and procedures for measuring properties of the materials from which these specimens are made. Properties, and test methods that are suitable, and necessary to characterize PB-1 moulding, and extrusion materials are listed in ISO 21302-2. 

What’s changed since the last update?  

BS EN ISO 21302-2:2019 supersedes ISO 89862:2009. BS EN ISO 21302-2:2019 includes some technical changes with respect to ISO 89862:2009. These include: 

• The symbol of general properties, and additional properties has been added 
• The type, and size of tensile sample ISO 5274(1B type test) has been modified to ISO 20753 (A1 or A2 type test) 
• The type, and size of the relative permittivity, dissipation factor, volume resistivity and surface resistivity samples have been modified from ≥ 80 × ≥ 80 × 1 to ≥ 60 × ≥ 60 × 2 
• The type, and size of the electric strength sample has been modified from ≥ 80 × ≥ 80 × 1 or ≥ 80 × ≥ 80 × 3 to ≥ 60 × ≥ 60 × 1 
• The type, and size of the water absorption sample has been modified from 50 × 50 × 3 or ø50 × 3 to 60 × 60 × 1
