What is EN ISO 14746:2014?

EN ISO 14746:2014 is an international standard that pertains to the identification of plastics. It specifies a coding system for the classification and designation of different types of plastic materials used in industry and commerce.

The Importance of EN ISO 14746:2014

Having a universal coding system for plastics is essential for several reasons. Firstly, it allows for easy identification and differentiation of various types of plastic materials, which aids in recycling and waste management efforts. Secondly, it ensures that manufacturers and consumers have clear and accurate information about the properties and characteristics of plastic products.

The standard also plays a crucial role in quality control and product traceability. By using the coding system outlined in EN ISO 14746:2014, manufacturers can maintain consistency and ensure that the correct materials are being used in their products. This standardization facilitates compliance with regulations and improves overall product safety.

Understanding the Coding System

The coding system provided by EN ISO 14746:2014 consists of a five-character code, which represents various attributes of the plastic material. The first character denotes the main polymer class, such as polyethylene (PE) or polypropylene (PP). The second and third characters represent additional polymers or modifiers if present. The fourth character signifies additives, and the fifth character identifies the processing method used.

For example, a code starting with "PP" indicates that the plastic material is made primarily of polypropylene. If the code also includes an "H" in the third position, it means there is a modifier present. The use of these codes simplifies communication and ensures accurate understanding among stakeholders throughout the plastic supply chain.

Benefits and Limitations

The adoption of EN ISO 14746:2014 brings numerous benefits to the plastics industry and society as a whole. It enables effective material sorting, increasing the efficiency of recycling processes and reducing environmental impact. The standardized coding system also facilitates product innovation and development, as it allows manufacturers to clearly identify and select suitable plastic materials for their specific needs.

However, it is important to note that EN ISO 14746:2014 covers only identification coding and does not provide information on other properties or attributes of plastics, such as mechanical strength or chemical resistance. Therefore, while it is a valuable tool in material classification, additional standards and specifications may be required to fully evaluate and utilize the suitability of a particular plastic material for different applications.
