Description

This Part of BS 6956 specifies requirements for the physical and sealing properties of jointing compounds for use with water, low pressure saturated steam, 1st family gases (excluding coal gas) and 2nd family gases. The jointing compounds are for use with screwed joints on pipework up to 50 mm nominal bore with threads up to R2 as specified in BS 21 and for use with the following:

cold water up to a working pressure of 7 bar²⁾ (gauge);
hot water up to a working pressure of 7 bar (gauge) and a working temperature of up to 100 °C;
1st (excluding coal based) and 2nd family gases up to a working pressure of 7 bar (gauge) and a working temperature of up to 150 °C;

NOTE 1 These are typically referred to as Towns Gas and Natural Gas respectively.
low pressure saturated steam up to a working pressure of 7 bar (gauge)

NOTE 2 For classification of 1st and 2nd family gases see BS 4947.

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

NOTE 4 For applications outside these limitations the manufacturer should be consulted.
