BS EN 1114-3:2019

What is BS EN 1114-3 – Plastics and rubber machines about? 

BS EN 1114-3 is the third part of the multi-series standard that provides methods and safety requirements for haul offs. 

BS EN 1114-3 deals with all significant hazards, hazardous situations and events relevant to haul-offs for cable, cable core, profiles and pipes for processing plastic and rubber, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Annex A). 

The following kinds of haul-offs are covered in BS EN 1114-3: 

• Caterpillar haul-offs 
• Belt haul-offs 
• Capstan haul-offs 
• Belt capstan haul-offs 
• Roller haul-offs 

The haul-off can function independently and begins at the product inlet opening and ends at the product outlet. Cutting units that are integrated with or attached to the haul-off are not covered. Take-off devices used on film or sheet lines are not covered. 

Note: BS EN 1114-3 does not apply to haul-offs that are manufactured before the date of its publication. 

Who is BS EN 1114-3 – Plastics and rubber machines for? 

BS EN 1114-3 on Plastics and rubber machines is relevant to: 

• Manufacturers of rubbers and wood adhesives  
• Health and safety bodies 
• Service providers  
• Any entity responsible for testing and safety of machinery  

Why should you use BS EN 1114-3– Plastics and rubber machines? 

In extrusion, the material is forced through a tool of specialized shape called a die to create continuous objects of a fixed cross-sectional profile. 

BS EN 1114-3 specifies requirements for Functional Testing which includes the evaluation of the functions and efficiency of guards and protective devices based on descriptions given in the information for use, safety-related design documents and requirements for use. 

Throughout BS EN 1114-3, you will find references to the machinery to which the standard applies as well as the hazards, hazardous situations, or hazardous events covered by the standard. 

BS EN 1114-3 standard covers all significant hazards, hazardous situations or hazardous events occurring in all phases of the machine life cycle when the haul-offs are used as intended and under reasonably permissible misuse conditions. 

Overall, BS EN 1114-3 is a comprehensive guide to provide safety requirements for machinery mouldings, so users will gain a comprehensive understanding of the process and the end product will be safer, more durable and will decrease chances of any mechanical failure. 

What’s changed since the last update? 

BS EN 1114-3:2019 supersedes EN 1114-3:2001+A1:2008, which is withdrawn and includes: 

• The performance levels of safety-related parts of control systems have been specified by EN ISO 13849-1:2015 
• The annexe for noise measurement has been revised 
• The revision of type-a and type-b standards have been considered 
• The list of significant hazards has been moved to an informative annexe 
• The safety requirements and protective measures have been modified by taking into consideration the technological progress in the plastics and rubber industry and the continuous development of the safety technology
