Specifies requirements for the design and fabrication of equipment to be lined and the application and inspection of the lining along with provisions for any repairs. It applies to rubber for lining steel and concrete equipment. Guidance is given on the properties of typical linings of this category including vulcanizing.

This Part of BS 6374 specifies requirements for the lining of equipment for the process industries using cold rubber.

It includes requirements for the choice of lining and its application and also requirements for inspection of the lining and the rectification of faults. It applies to equipment fabricated in metal or concrete. The materials considered include natural and synthetic rubbers applied as unvulcanized or prevulcanized sheet.

Brushed or sprayed rubber linings are not included.

NOTE 1 The linings may be applied at the applicator’s works or on site.

Requirements for design and fabrication of the equipment and the state of preparation necessary for the surfaces to be lined are specified in section 2.

Requirements for storage, handling, transportation and installation of the lined equipment are specified in section 8.

NOTE 2 The titles of the publications referred to in this standard are listed on the inside back cover.
