Description: Components have the same design features and structure. These can be grouped together based on similar manufacturing techniques and quality assurance controls.; Name: Type connection socket A1
Description: a group of construction elements with the same construction features and the same construction, which can be collated for the construction type approval and quality conformity controls as a result of similar manufacturing methods. they are generally allocated to a construction type specification. Note: in certain cases, construction element from different construction type specifications can be viewed as belonging to the same type and hence collated for the construction type approval and quality conformity controls; Name: Construction type of the connection, muff A1
Description: maximum value of the mass of the liquid at design temperature divided by its volume, when stating the density, the unit of density used, together with the temperature, shall be explicitly given, for example kilogram per cubicmeter or gramme per mililiter at t°C (see the note), the standard reference temperature for international trade in petroleum and its products is 15°C (see ISO 5024), but other reference temperatures may be required for legal metrology or other special purposes.; Name: maximum density at design temperature
