BS 7961:2004

This standard BS 7961:2004 Specification for a device for measuring the static vertical mass (noseweight)at the coupling point of the towed vehicle. is classified in these ICS categories:

• 43.040.70 Couplings
• 43.100 Passenger cars. Caravans and light trailers
• 17.060 Measurement of volume, mass, density, viscosity

This British Standard specifies requirements for devices intended to measure the static vertical mass of towed vehicles. Such devices are commonly known as “noseweight gauges”.

This British Standard only applies to all towed vehicles up to 3 500 kg maximum technical permissible laden mass.

NOTE Normally such towed vehicles are fitted with a 50 mm ball coupling device but the manufacturer of a noseweight gauge may also specify its suitability for use with other coupling devices.
