Introduction
This European Standard calls for the use of substances and procedures that may be injurious to health and/or
the environment if adequate precautions are not taken. It refers only to technical suitability and does not
absolve the user from legal obligations at any stage.
Protection of the environment is a key political issue in Europe and elsewhere. Protection of the environment
is taken in a very broad sense. What is meant is the total life cycle aspects of, e.g. a product on the
environment, including expenditure of energy and during all phases from mining of raw materials, fabrication,
packaging, distribution, use, scrapping, recycling of materials, etc.
NOTE Annex F indicates which clauses in this standard address environmental issues.
Provisions have to be restricted to a general guidance. Limit values are specified in national laws.
It is recommended that manufacturers develop an environmental management policy. For guidance see
ISO 14000 series
It has been assumed in the drafting of this European Standard that the execution of its provisions is entrusted
to appropriately qualified and experienced people.
All pressures are gauge pressures unless otherwise stated.
NOTE This standard requires measurement of material properties, dimensions and pressures. All such
measurements are subject to a degree of uncertainty due to tolerances in measuring equipment etc. It may be beneficial
to refer to the leaflet “measurement uncertainty leaflet (SP INFO 2000 27 uncertainty pdf)”,
