IS 10496 : 2024 Feed Water, Boiler Water and Condensate Water for High Pressure Boilers - Specification
| ICS 13.060.50, 27.060.30 | CHD 13 |
1 SCOPE
1.1 This standard prescribes requirements for feed water, boiler water, steam and condensate for watertube boilers.
1.2 The requirements prescribed are for boilers operating at pressures above 5.9 MN/m2 (5.9 × 106 Pa) during normal operation of the unit with normal water level in boiler and with nominal output at nominal pressure. Any serious deviation from the above shall be discussed in advance with the boiler manufacturer.
