What is DIN ISO 11469 and why is it important for plastics products
DIN ISO 11469 is a standard that specifies a system of uniform marking of products that have been fabricated from plastics materials. The standard is based on the international standard ISO 11469:2016[^1^] [^2^], which was last reviewed and confirmed in 2022[^2^]. The purpose of the marking system is to help identify plastics products for subsequent decisions concerning handling, waste recovery or disposal[^1^] [^2^].
The marking system consists of two elements: a basic mark and an optional mark. The basic mark indicates the generic identification of the plastics material, using the symbols and abbreviated terms given in ISO 1043-1, ISO 1043-2, ISO 1043-3 and ISO 1043-4[^1^] [^2^]. For example, PE for polyethylene, PP for polypropylene, ABS for acrylonitrile-butadiene-styrene, etc. The optional mark provides additional information on the composition or properties of the plastics product, such as polymer blends or alloys, special additives, fillers, reinforcements, recyclates, etc[^1^] [^2^]. For example, PE+PP for a blend of polyethylene and polypropylene, PE-LD for low-density polyethylene, PE-RT for polyethylene of raised temperature resistance, etc.
The method of marking is subject to agreement between the manufacturer and the user of the plastics product. The standard does not specify the process or processes to be used for marking, nor the precise details of the marking, such as the minimum size of the item to be marked, the size of the lettering, or the appropriate location of the marking[^1^] [^2^]. However, the standard recommends that the marking should be legible and durable under normal conditions of use and storage[^1^] [^2^]. The standard also states that the marking system is not intended to supplant, replace or interfere with the requirements for labelling specified in product standards or legislation[^1^] [^2^].
DIN ISO 11469 is important for plastics products because it facilitates their identification and classification for various purposes. For example, it can help consumers to choose products that are suitable for their intended use and compatible with their existing equipment. It can also help waste management operators to sort and separate plastics products for recycling or disposal. Furthermore, it can help authorities to monitor and regulate the production and trade of plastics products in accordance with environmental and safety standards[^3^] [^4^].
DIN ISO 11469 also provides some examples of marking for different types of plastics products, such as pipes, films, sheets, bottles, containers, etc. The examples illustrate how to apply the basic and optional marks according to the standard. However, they are not intended to be exhaustive or mandatory[^1^]. The users of the standard should consult the relevant product standards or regulations for specific marking requirements.
Some examples of marking for plastics products are[^1^]:
>PE< for a single-constituent product made of polyethylene
>PE+PP< for a polymer blend product made of polyethylene and polypropylene
>PE-LD< for a single-constituent product made of low-density polyethylene
>PE-RT< for a single-constituent product made of polyethylene of raised temperature resistance
>PP-MD30< for a single-constituent product made of polypropylene containing 30% by mass of a mineral powder additive
>PVC,PUR,ABS< for a product made of three components, the visible one being a thin coating of poly (vinyl chloride) over a polyurethane containing an insert of acrylonitrile-butadiene-styrene that is the major component by mass
>PET (REC50)< for a single-constituent product made of poly (ethylene terephthalate) containing 50% by mass of recyclate
The marking system specified by DIN ISO 11469 is based on the international standard ISO 11469:2016, which is also adopted by other countries and regions. However, there may be some variations or differences in the marking requirements or practices among different markets. Therefore, it is advisable to check the local regulations or standards before exporting or importing plastics products to ensure compliance and avoid confusion[^2^] [^3^] [^4^]. 248dff8e21
