DGOF floated tender and we quoted and got the order from DGOF for the first time. 3 plates 3000 x 1200 matched and assembled mounted on special MS Fabricated Stand. A highly engineered product at that time. Plates were made mounted on stand duly assembled and scraped to the required accuracy. As per order the plate has to be inspected by DGS&D inspector. The inspector visited and inspected and accepted the plate for flatness accuracy. However, he said the plate has to pass for deflection test. Indian Standard for Surface Plate did mention deflection test. PV (GMT founder) accepted inspector's point and GMT made a Beam Comparator which is used for deflection test. This was designed and made strictly as per standard. The deflection was measured and our plate conformed to standard. PV was very impressed by the inspector of DGS&D, Mr. V. Subramaniam GMT used his services after his retirement and bought a number of standards for our library viz. IS and DIN.
