BS EN 13523-24:2017

What is BS EN 13523-24 - Metal’s resistance to blocking and pressure marking about?   

Coil coating makes metal more durable and more corrosion-resistant than most other post painted metal. BS EN 13523-24 is the 24th part of the BS EN 13523 series that contains test methods on coil coated metals. 

BS EN 13523-24 specifies the procedure for determining the resistance to blocking and pressure marking of an organic coating on a metallic substrate. 

Who is BS EN 13523-24 - Metal’s resistance to blocking and pressure marking for?  

BS EN 13523-24 on metal’s resistance to blocking and pressure marking is useful for:  

• Coil coated metal industries  
• Metal coil product manufacturing companies  
• Metal coil transport companies   
• Quality management teams 

Why should you use BS EN 13523-24- Metal’s resistance to blocking and pressure marking?   

Metals are coated with polyesters, polyurethanes, plastisols, polyvinylidene fluorides (PVDF), epoxies, backing coats, primers, and laminate films. Many layers of coating are applied to each product. The pressure generated within a coil or a stack of sheets can affect the coating surface and cause marks of gloss transfer, plasticizer migration, etc. and even blocking/sticking. 

BS EN 13523-24 guides on: 

• Test panels 
• General procedure 
• A rating scheme for blocking/sticking 
• Transfer of gloss and pressure marks 
• A rating scheme for pressure marking 

BS EN 13523-24 helps you assess metal’s resistance to blocking and pressure marking so that end customers get a superior quality product. 

What’s changed since the last update?   

BS EN 13523-24:2017 supersedes BS EN 1352324:2004. BS EN 13523-24:2017  includes some technical changes with respect to BS EN 1352324:2004. These include:  

• The in-laboratory jargon “eye to the sky” and “eye horizontal” are explained to a more technical term  
• The terms “light” and “heavy” in 7.2.2 are explained  
• The text has been editorially revised and the normative references have been updated
