Scope
This part of ISO 7628 specifies the dimensions and marking for thermoplastics tubing for use in air braking systems on road vehicles.
The tubing defined in this part of ISO 7628 belongs to two possible categories:
— tubing for use up to a maximum working pressure of 1 000 kPa;
— tubing for use up to a maximum working pressure of 1 250 kPa;
and within a temperature range of - 40 ℃ to + 100 ℃.
Coiled tubing for use between tractors and trailers is not covered by this part of ISO 7628.
ISO 7628-2 deals with installation on the vehicle and test requirements.
note: 1) 1 kPa = 10 bar
2) Reduction of the lower temperature limit will be considered for a future revision of this part of ISO 7628.
