In the following abstract an overview is given about the basic rules and standards for large diameter plastic pipes. The main focus made from German/European view on the thermoplastic pipe materials Polyethylene and Polypropylene.
In the list the standards are marked according their relation to:
It is of prime importance for the industry to be geared to the established standards.
Without adequate standards there would be no orientation on the free market. This concerns designer, planer, fabricators, operator, testing institutes as well as the manufacturers and his quality management. Of course this does apply also for large diameter thermoplastic pipes. Especially, because thermoplastic materials are with around 70 years of experience still a young material group, which results in immense drive and innovation.
In the standardization of plastic pipes there are many national activities, whereas the pursuit of transparency slowly brings unification of technical standards. Subsequently we concentrate on standards and rules of following institutions:
...means “American Society for Testing and Materials” and was founded 1898 by a group of scientists and engineers. The membership is composed of manufacturers, operators, governments and graduates form more then 100 countries.
...means “German Association for Water, Wastewater and Waste”, arose from the ATV, which was founded in 1948.
...means „British Standards Institution“ and was found in 1901.
...means European Committee for Standardization, was found in 1961 and represents more than 30 countries with the objective of coordination of national standards. Those are published as EN.
...means „German Institute for Standardization“ and was found in 1917. DIN is, with more than 30.000 documents, one of the most important organization for standards of the world today.
...means „German association for welding and similar methods” and is one of the most important institutions for the range welding of plastics. The rules of DVS are worldwide known and accepted. Also guidelines for static calculations of pipe systems or tanks are included.
...means „International Organization for Standardization“, was found 1946 in London. By now 150 countries are represented in the ISO.
If standards are harmonized also the nomenclature is unified - for example look at “DIN EN ISO 899” At all CEN member countries and in ISO as well you find at number 899 the same standard “Plastics – Determination of creep behavior”.
But also rules of national associations have international importance for standardization of thermoplastic pipes. Often found in tender specifications are rules from e.g.:
DVGW - German Technical and Scientific Association for Gas and Water
AWWA - American Water Works Association
