• the tBU inspection body performs a continuous surveillance, assessment and approval of the factory production control (Factory Control Assessment);
• the TENAX products comply with the published specifications;
• the TENAX products comply with the essential requirements of the relevant European construction legislations.

According to the European Directive, starting from October 2002, the products for construction without CE marking will not be accepted for sales within European market. The European Union's 'New Approach directives' are mandatory on all member countries to enact through national legislation. This legislation requires manufacturers to display CE Marking on their product, packaging and accompanying literature. Where a new approach directive is in force, it is (with few exceptions) an offence to place a product on the market without CE Marking. The manufacturer is legally responsible for ensuring that the product confirms to the requirements of the directive and for applying CE Marking.
CE Marking is one important measure that the E.U. has adopted to establish the single market and faster economic development for the member states. The objective of the directives is to simplify the movement of goods into and within the E.U.. This may eventually lead to the free movement of goods throughout Europe as more and more European countries are expected to join the E.U.. The European Commission thus refers to the CE Marking as a "Passport" which allows products to be freely circulated within the E.U. single market. Consumers will consider CE Marking on a product as an indication of conformance to lay down minimum standards, and therefore a minimum level of quality, which other products may lack. CE Marking is thus for many consumers a "Symbol of Quality."
CE Marking is the symbol as shown on the bottom of this page. The letters "CE" are the abbreviation of French phrase "Conformité Européene" which literature means "European Conformity".
CE Marking on a product is a manufacturer's declaration that the product complies with the essential requirements of the relevant European health, safety and environmental protection legislations, in practice by many of the so-called Product Directives, which contains the "essential requirements" and/or "performance levels", and "Harmonized Standards" to which the products must conform. Harmonized Standards are the technical specifications (European Standards or Harmonization Documents), which are established by several European standards agencies.
