EN ISO 14000 series (#see [8], [9] and [10]$). Provisions need to be restricted to a general guidance. Limit values are specified in national laws. It has been assumed in the drafting of this European Standard that the execution of its provisions is entrusted to appropriately qualified and experienced people. All pressures are gauged unless otherwise stated. NOTE This European Standard requires measurement of material properties, dimensions and pressures. All such measurements are subject to a degree of uncertainty due to tolerances in measuring equipment, etc. It might be beneficial to refer to the leaflet “measurement uncertainty leaflet" SP INFO 2000 27 #[15]$.
