DESCRIPTION

BS 6949:1991


This standard BS 6949:1991 Specification for bitumen-based coatings for cold application excluding use in contact with potable water is classified in these ICS categories:
  • 25.220.60 Organic coatings

This British Standard specifies performance and marking requirements for a range of bitumen-based, solvent-borne coatings. It covers coatings for cold application by either brushing, spraying, rolling or dipping processes intended to give a coat for the corrosion protection and waterproofing of substrates including iron and steel.

Two types, each with three classes, are included. All of these are suitable only for applications where the coating will not be in contact with potable water (see BS 3416).

The level of gloss of the finished film is not specified in this British Standard.

NOTE 1 These bitumen coatings, are neither intended to withstand hot conditions, as on boilers, smoke stacks, etc., for which special coatings should be obtained, nor to resist contamination with mineral oils or paint solvents, all of which conditions will cause softening of the film.

NOTE 2 Guidance on the use of bitumen-based coatings is given in Appendix A, BS 5493 and BS 6150.

NOTE 3 The titles of the publications referred to in this standard are listed on the inside back cover.


Requirements for two types, each with three classes, of coatings not suitable for use with potable water.
