What is BS EN 1417 – Plastics and rubber machines about? 
BS EN 1417 deals with all significant hazards, hazardous situations and events relevant to two-roll mills for the processing of rubber and/or plastics, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).
BS EN 1417 covers two-roll mills as defined in 3.1.
BS EN 1417 does not deal with the design of a local exhaust ventilation system that may be necessary in specific applications of the machine not known by the manufacturer.
BS EN 1417 is not applicable to two-roll mills manufactured before the date of its publication as a European Standard.

Why should you use BS EN 1417– Plastics and rubber machines? 
machine with two counter-rotating cylinders (known as mill rolls) which are not covered, which may be smooth or grooved, and whose axes are on substantially the same horizontal plane are called two-roll-mills.
BS EN 1417 specifies safety requirements for two-roll-mills which include 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 1417, 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 1417 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 1417 is a comprehensive guide to provide safety requirements for plastic and rubber machinery, so users will gain a comprehensive understanding of the process, and the end product will be safer, more durable, and will decrease the chances of any mechanical failure.
