Press Release No 13 – June 2013 CE Marking becomes mandatory
The UK was one of four countries in the European Union where CE marking of construction products has been voluntary. However, a new Regulation has replaced the old Construction Products Directive and lays out conditions for its implementation. It has become mandatory for construction products falling under the scope of the Regulation to have a declaration of their performance, and to carry the CE marking to demonstrate this, before they can be put on the market. This is a legal requirement. The CE Mark had to be affixed by the end of June 2013.
It is applicable to the use of harmonized EN (European Norme) product standards. For some products, depending upon the level of assessment and verification of constancy of performance (AVCP) that is deemed necessary, a Notifying Body assesses the producer’s capability to manufacture the product and issues a certificate that would allow affixing of the CE Mark. EN 13808 Bitumen and bituminous binders — Framework for specifying cationic bituminous emulsions falls into this category.
It is necessary to identify the key test properties, characterized by class in the product standard. They are based on the essential characteristics, but may include voluntary properties, depending on the intended use and on the local climatic conditions. Test properties must relate to the performance of at least one of the essential characteristics of the product. Care should be taken to make property class selections which are compatible and realistic.
For the purpose of CE Marking, key properties from EN 13808 may include:
for the Bitumen Emulsion
- Breaking behaviour (e.g. breaking value using Forshammer filler)
- Viscosity (efflux time/ dynamic viscosity)
for the Binder recovered, stabilised and aged
- Consistency at intermediate temperature (penetration)
- Consistency at elevated temperature (e.g. softening point)
- Cohesion – modified binders only (e.g. by pendulum test)
Test reports on the properties that are relevant to the intended use of the product must be kept by the manufacturer for at least ten years.
Manufacturers must implement all of the requirements of Factory Production Control (FPC) or quality system that includes making the necessary checks and carrying out the appropriate tests at the required frequency.
The Notified Body makes an initial inspection of the plant to ensure that FPC has been implemented satisfactorily and that test properties that are appropriate to the product comply with the requirements (selected classes) of the product standard. The Notified Body is also responsible for making continuous surveillance of Factory Production Control.
A “Declaration of Performance” (DoP) is drawn up by the manufacturer. The main task here is to list the classes of the test properties that are appropriate to the intended use of each product. This is consistent with the information that follows the CE marking symbol and that has to be included on commercial documents. A shortened CE marking with the minimum information should be affixed on packaging or be given on a Delivery Note.
In summary, Road Emulsion Association members have undertaken the following to place cationic bitumen emulsions in accordance with EN 13808 on the market:
- Identified the products for sale
- Selected the test properties and classes for each product, appropriate for the intended use
- Provided test reports that show test results corresponding to selected classes
- Implemented the requirements of FPC
- Appointed a Notified Body to inspect the plant and check FPC
- Prepared a DoP for each product
- Affixed the CE Mark
