BS 4840-1:1985

What is BS 4840-1 – PUR foam specification for transport about?   

Rigid polyurethane (PUR) foam is recognized for properties that make it the preferred material to transport temperature-sensitive merchandise.  

BS 4840-1 specifies requirements for the composition, physical properties and dimensional tolerances of PUR foam in slabs (blocks, boards and sheets) for the thermal insulation of transport containers and insulated vehicle bodies. 

Who is BS 4840-1 - PUR foam specification for transport for?  

BS 7344 on ‘PUR foam specification for transport’ is useful for:  

• The plastics industry 
• The rubber industry 
• The transport / logistics / shipping industry 
• The chemical industry 
• Manufacturers of PUR foam slabs 
• Product design engineers / innovation teams 
• Quality control / testing personnel 
• Refrigeration / insulation researchers 

Why should you use BS 4840-1 – PUR foam specification for transport?   

During transport, temperature sensitive merchandise such as food, pharmaceuticals, and fine chemicals need to be kept at constant temperatures even when external temperatures vary markedly. Besides high insulation and hygiene, PUR is the preferred insulation material due to its light weight, high loading capacity, and ease of unloading. 

BS 4840-1 guides you with aspects of PUR foam slabs such as: 

• Designation 
• Composition and form 
• Sampling 
• Physical properties 
• Dimensional tolerances 

Appendices provide you with details such as: 

• Guidance for designers 
• Burning properties of PUR foam 
• Guidance intended to minimize fire hazards 
• Method for the determination of apparent water absorption  

Detailed tables illustrate various aspects of PUR foam slabs to make the specification clearer. 

BS 4840-1 guidelines help you to manufacture high quality PUR foam slabs for the packaging, insulation, and transportation needs of users. This helps temperature-sensitive products remain intact in during transportation.
