Описание (английский):

Specifies the main characteristics of connections used for checking response times and pressure levels for braking equipment fitted on road vehicles, and gives the open space requirements that shall surround the pressure test connection and the protection against corrosion. Passenger cars and their derivatives are excluded. This second edition cancels and replaces the first edition (1976).

Overview

ISO 3803:1984 specifies the main characteristics for a hydraulic pressure test connection used to check response times and pressure levels of braking equipment fitted on road vehicles (excluding passenger cars and their derivatives). The second edition (1984) replaces the 1976 edition and establishes dimensional, installation, accessibility and corrosion-protection requirements to ensure reliable, leak‑free brake system testing.

Key topics and requirements

Field of application: Applies to hydraulic braking systems on road vehicles (passenger cars and derivatives excluded).

Dimensional characteristics: Defines key geometry in millimetres (examples in the standard include 22 mm across flats and an M18 × 1.5 thread). Other unspecified dimensions are chosen per application.

Installation position:

Thread for the test apparatus must be positioned above the brake-line connections (i.e., pointing upwards).
The test connection can be located between the master cylinder and wheel cylinders.
Seal ring should be captive in the sealing cap to ensure leak-free operation.

Accessibility and open space:

Test connections must be readily accessible so connecting the test apparatus does not kink brake lines or subject the test point to torsion/bending stresses.
Design must protect inspectors from injury during use.

Leakage prevention: Connections must allow removal of the sealing cap, attachment of test apparatus and execution of tests without introducing additional mechanical stress that could compromise sealing.

Corrosion protection:

Pressure test connections must resist corrosion.
Must withstand the Neutral Salt Spray (NSS) test specified in ISO 3768 for at least 96 hours.

Applications

ISO 3803 is practical for:

Designing and specifying brake-system test points on commercial vehicles, trucks and buses.

Manufacturing pressure test fittings, sealing caps and test adapters that interface with brake diagnostic equipment.

Workshop procedures and inspection protocols for hydraulic brake performance checks.

Vehicle assembly and service manuals to ensure test connections are accessible and corrosion‑resistant.
