NBN EN ISO 1307:2008

ISO 1307:2006 specifies the sizes of rubber and plastics hoses and the minimum and maximum inside diameters permitted for each hose size. For this purpose, hoses are divided into four types according to the process by which they are manufactured. The standard also specifies tolerances on cut lengths of rubber and plastics hose for industrial and automotive applications. This standard is intended to be used with the relevant hose product standard unless there is justification for using a different hose size or unless a hose size needs a different inside-diameter range for a particular application.
