TEST EQUIPMENT FREQUENCY OF CALIBRATION (i) Blaine’s apparatus Daily with licensee’s own Standard cement

sample and weekly with standard cement samples supplied by NCCBM.

(ii) Compressive strength testing machine.

Once in a month with Licensee’s own Proving Ring and the Proving Ring shall be Calibrated once in two years from the Accredited independent agency or NPL or Proving Ring manufacturer.

(iii) Autoclave Pressure Gauge Once in a month by licensee’s own dead weight pressure gauge tester OR once in six months from accredited independent agency or by manufacturer of such gauges.

(iv) Vibration Machine

Once in a month by licensee’s own Tachometer. The tachometer shall be calibrated once in a year from accredited independent agency.

(a) Name of the manufacturer and his registered trade mark, if any. (b) The words 'Ordinary Portland Cement, 33 Grade'. (c) Net Quantity in kg. (d) The words 'Use no Hooks'. (e) Address of Manufacturer. (f) Type and percentage of performance improver(s) added, in case of

addition of performance improvers. (g) Batch /Control unit number in terms of the week, month and year of

packing. NOTE: (i) For each calendar year the first week shall be counted as 7 days

from 1st of January and subsequent weeks numbered serially accordingly. In such an event, the bags shall be marked as W01 ……. W51.. etc.

6.0 BATCH: For the purpose of this scheme all cement of one consignment received

shall constitute one batch.

6.1 Only ISI Marked Ordinary Portland Cement, 33 grade shall be used for packing. At a particular time only one batch of cement shall be packed. Another batch of cement shall be packed only after completion of packing of the first batch. At all stages of packing, the packer shall maintain appropriate controls and checks to ensure that there is no chance of mixing two different batches of the cement.

6.2 Test Certificate of each original batch of cement shall be obtained from the supplier and test results recorded.

7.0 LEVELS OF CONTROL: The tests, as indicated in Table 1 attached and at the

levels of control specified therein, shall be carried out on the whole production of the factory which is covered by this scheme and appropriate records and charts maintained in accordance with paragraph 2.0 above.

7.1 On the basis of tests and inspection, the decision regarding conformity or otherwise of the control unit to a given requirement shall be made.

7.2 Weighment: 12 filled bags shall be taken at random every hour in each shift of

operation and weighed and appropriate records maintained (See Form 3 for record). The bags shall be so chosen for weighment that bags from each nozzle are taken for weighment. Records of such weighment shall be as per Form No.3.

8.0 REJECTIONS: A separate record shall be maintained giving information relating

to the rejection of the production not conforming to the requirements of the specification and the method of its disposal. Such material shall in no circumstances be stored together with that conforming to the specification.
