1- "This unknown element", the glass block!
With this short summary we wish to provide concise and complete information about the standards and regulations that govern glass block production, use and marketing.
The GLASS BLOCK is "transparent" and, similarly, all the indications and information available at the time of purchasing and/or handling must also be transparent.
The packaging is consequently of primary importance since it says a lot about the "contents" and many of the indications are MANDATORY for the purpose of ensuring correct identification of the product.
January 1st 2007 was an important date as it marked the entering into force of the regulations that explicitly govern these obligations!
Glass blocks: features and standards
Glass blocks are identified, characterised, regulated, and classified by a variety of different features and regulations.
They are coded at a European level by the EN standards (that have different names in the different Member Countries of the European Union, e.g. UNI in Italy, DIN in Germany, etc.) and by the ISO standards which are valid all over the world.
The difference between the two is that once the EN standards have been issued and adopted at a national level by all the EU Member States they become official and are therefore binding (with legal force) for all effects and purposes within the European Union. On the other hand, ISO standards are only valid as “recommendations” worldwide. It must be noted that EN and ISO standards do not diverge substantially with regard to contents or purpose (ISO standards normally adopt EN contents).
There are numerous EN standards pertaining to the glass block sector that have different purposes and objectives. The diagram alongside illustrates the main current standards: it is important to note that technical commettees are still at work and several standards are still in progress.
SEVES TECHNICAL AND SALES DEPARTMENTS ARE IN ANY CASE ALWAYS AVAILABLE FOR ASSISTING THEIR CUSTOMERS BY PROVIDING ALL THAT IS NECESSARY TO ENSURE CORRECT DESIGN AND INSTALLATION OF THEIR GLASS BLOCKS.
