Enamel Quality
Vitreous Enamel is an extraordinary material. Extraordinary in its  performance as well as in its appearance. Therefore it is important that enamelled products are produced with the right skills and technik.
So the European Enamel Association (EEA) made it to its business, to develop, maintain and audit "Quality Requirements“, which are continuously harmonised between the EEA member associations.

EEA Quality Requirements, how do they work?
It is important to have a good understanding of the intent and the scope  of the EEA Quality Requirements. The EEA Quality Requirements are the necessary requirements for the enamel layer of enamelled products.
A simple example illustrates the implication of this statement: An enamelled washing machine, displaying the EEA sign does not necessarily wash properly. The EEA sign guarantees that the enamel layer fulfills the EEA reqirements, like colour stability, scratch resistance,  adherence, corrosion resistance and resistance against detergents needed to clean laundry.
Therefore it is important to realise that the EEA sign only covers the quality of the enamel layer.
Exceptions to this rule
For many products a well-applied enamel coating is essential for the  functionality of the product. A cooking pan with a base which is not  flat, may be well enamelled, but will not perform well on an electrical  heating plate. It is even possible that that the non-uniform heating of  the base damages the enamel. Because surface flatness is an essential  condition for a proper use of the pan and at the same time for the  durability of the enamel layer, EEA specifies quality requirements for  surface flatness of cookware.
Another example refers to heat exchanger  pannels. These pannels are packed in large industrial installation. During the packing in  the baskets no damage may occur, since the pannels will corrode after  installation. Therefore requirements have been included for the  enamelled plates after packing.
Enamel has to comply with many requirements. In the EEA Quality Requirements the following subjects are included:

  • all procedures for testing, obtaining and retaining the EEA sign

  • uniform and internationally standardised definitions of all terminology, used in the requirements

  • quality requirements for enamelled products with EEA sign

  • test methods to be used to test the products. In principle these are  test methods described in international standards, such as ISO- and CEN standards. In cases where no ISO or CEN standards exist, well-known  national standards or EEA specifications are referred to quality of the basic materials, such as steel, cast iron, enamel frit and ways to test the properties of these materials

  • the characteristic properties of (good) enamel layer, such as  corrosion resistance, gloss, hardness, heat - and thermal shock  resistance, but also cleaning- and antibacterial properties and the  impact of material and process on the environment

  • The product categories for which a sign can be obtained and the specific requirements for these categories
This is an extensive list, asking a lot from the producer and from the  product. It is a list that can be updated and extended regularly. Each  party wanting an addition or adjustment of the requirements can apply to  the EEA. The Executive Committee of the EEA decides on the adjustments  and additions of the quality requirements. Every 3 years the  requirements will be updated to the “state of the art”. A request for  adjustment or extension of the requirements is certainly not restricted  to the enamel producers wanting to obtain an EEA sign for their  products. A customer, regularly purchasing enamelled ware and desiring  standardised requirements can also make a request.
