- Chemical
& Physical Testing :
Materials used for equipments and structurals i.e. M.S.Plates,
Bars, Seamless Pipes, Forgings etc shall be tested as per
IS:2062 from approved laboratories viz. Fan Services, Nasik;
Premier Electrodes, Nasik etc. All plates shall be ultrasonically
tested.

& Stress Relieving Tests :
Hardening & Stress Relieveing Tests for Wheels, Gear
Box Castings, Gears and Pinions etc. is done as per IS:1570
from reputed laboratories viz. Unique Treatments, Nasik.
- Welding
All butt welds on structural members subject to tension
are radiographically tested as per IS:4853 from Radiographic
Services, Mumbai. All other non-load taking welds are to be
visually examined and as per ASME - Section VII.
- Ultrasonic
Testing :
As
per IS:3664 for thickness greater than 50mm.
