Furthermore, It is desirable that, after the initial adjustnent; a volume ofat least 1/100 of the volume of the standard welght remains empty: 6, Material Standard welghts are in general made of grey cast Iron. They may be made of one or more other materials, provided the provisions of paragraph & are observed: The materlal used must be of such hardness and strength that they wlthstand the bads and shocks Ilable to occur under normal conditions of use: 7 . Surface condltlon The standard welghts may be coated with materials suitable tor providing protectlon against corrosion by rendering thelr surface impermeable. This coating must wlthstand shocks ad atmospheric conditions: Zinc-plating Is a example of a coating which meets with these specifications: 8.

The absolute error for various denominations of standard weights shall be as given In Annexure I, These maxlmum perisslble errors for the standard welghts must therefore be compatible wlth the number of scale divisions on the machines whldh they " areintendto verify: Furtherore; the density of standard welghts must be such that a varlatlon of + 10 per cent ambient alr density, with respect to its reference value, does not produce a variation, In the result of weighlng the standard weight In alr; exceeding 1/4 of its maxlmum permissible error By way of appllcation of these requirements, the follwlng table glves examples of the relation amongst (a) the maxlmum number of scale dlvlslons ` n on welghing machines under verlfkation (assumed to be in accuracy dass III); (b) the maxlmum permissible positlve or negatlve relative error on standard welghts used for inltial verification of these machines; and (c) the corresponding lower limit for the density of the standard weights:

(For value of Qn and Qmax) The pressure loss within the meter may be measured with the help of manometer or differential pressure gauge or pressure gauges provided each at up-stream and down-stream: While the meter(s) are being tested for accuracy at Qn an Qmax' the readings between the Up-stream and down-stream in the pressure gauges P and P or manometers shall be taken for the purpose of computing the value of loss of pressure wlthin the meter; In case one meter is being tested the difference between the pressure gauge reading of PI and P2 or the dlfferential pressure shown by the dlfferential pressure gauge/manometer shall be the loss of pressure withln the meter In case loss of pressure is being measured for more than one meter at time, the difference between the readings of P and Pz be divlded by number of meters to obtain the loss 0f pressure in an individual meter; This, however; shall contain the line loss(es) contrlbuted by the connecting pieces between the two meters: For an accurate approach Iine loss(es) may be measured by joining the up ad down-stream spacers/pipe faces together in the absence of the meter/s (carefully avoiding protrusion into the pipe bore or misalignment of the two faces), and measuring the plpe pressure loss/line losses of the measuring section for each test at appropriate flow rates: While computing loss of pressure, across 1 or N number of meters tested in series, the loss registered by spacers/pipes in line losses be subtracted from the total value of pressure loss registered by difference between the readings of pressure gauge at Up-stream and down-stream to obtain the value of loss of pressure across 1 Or N number of meters; 3. Pressure Tlghtness Test The meter(s) shall be subjected to hydrostatic continuous water pressure Of (1) 1.6 MPa for 15 minutes, and (2) 2.0 MPa for 1 minute: Note Only when the meter has qualified for (1) above; it should be subjected for the test for (2) abxve: After:mounting the meter(s) on the test bench, the pump or the pumping medium should be switched on to let the-water flow through the meter(s) and
