1 SCHEME OF TESTING AND INSPECTION FOR CERTIFICATION OF ACCORDING TO IS 11722:1986 (Including Amendment No. 1 to 5) 1. LABORATORY A laboratory shall be maintained which shall be suitably equipped and staffed where different tests given in the specification shall be carried out in accordance with the methods given in the specification. 2.
