3 terms and definitions
Column F terms and definitions apply to this standard.
3.1
Overfill prevention system
A system consisting of an anti-overflow sensor and an anti-overflow socket connected by a cable.
3.2
Overfill prevention optic sensor
A sensor installed at the top of the tank to determine whether the liquid level in the tank exceeds a specified height.
3.3
Overfill prevention socket
Interface for anti-overflow system and external connection.
4 Requirements
4.1 Basic requirements
4.1.1 Each component of the anti-overflow system shall meet the requirements of this standard and shall be manufactured according to the product drawings and technical documents.
4.1.2 The raw materials, purchased parts, and outsourced parts applied to each component of the anti-overflow system shall meet the requirements of relevant standards and be collapsed through experience.
Before use.
4.2 Materials
4.2.1 The selection of housing material and sealing material must fully consider its compatibility with the medium in contact.
4.2.2 The housing of the sensor and socket in the anti-overflow system should be made of aluminum alloy or stainless steel, and should not be made of cast iron and non-metallic materials
