Owner/EIL/ LSTK contractor or indirectly through the sub-Suppliers.1.2 Any post order deviation from this specification must be approved by Owner/EIL in theDeviation/ Waiver Permit format (No. 5-0000-0180-F1) enclosed with Material Requisition.1.3 This specification covers the procedures and methodology to be adopted to assure that thechemical composition of the material is consistent with the material specifications as specifiedin purchase documents using 'Alloy Analyzer' at the time of final inspection before dispatch.1.4 The scope of this specification shall include but shall not be limited to Positive MaterialIdentification (PMI) to be performed on Materials listed below:1.4.1 For alloy Steel materials as below:

Alloy Steel Pipes including Clad PipesAlloy Steel Flanges & ForgingsAlloy Steel Fittings including Clad FittingsAlloy Steel FastenersAlloy Cast & Forged steel valvesAlloy Steel Instrumentation Items (Control Valves, Safety Valves etc.)Longitudinal Pipe & Fittings Welds.Gaskets (for Ring Type Joints)

1.4.2 For Carbon Steel materials as below:All Carbon Steel Piping items under NACE or HIC or H2Carbon Steel flanges and valves (Rating 900# and above)Carbon Steel Pipes & fittings for following thicknesses:Size 1 - 2 NB : Sch 160 & aboveSize 3 NB : Sch XS & aboveSize 4 - 12 NB : Sch 120 & aboveFollowing items shall be excluded from scope of PMI examination.Gaskets other than for Ring Type JointsInternal Components of Valves

1.5 All grades of material supplies including Stainless Steels shall be liable for PMI test at site. Incase of any defective materials being found at site, the Supplier shall be responsible to effectreplacement of such defective materials at project site without any delays to the satisfaction ofEIL site RCM (Resident Construction Manager).

2.0 REFERENCE DOCUMENTS2.1 API Recommended Practice 578 (First Edition, May 1999) - Material Verification Program forNew and Existing Alloy Piping Systems.3.0 DEFINITIONS3.1 Supplier Any Supplier or Manufacturer on whom an order is placed for the supply of referreditems. This definition shall also include any sub-Supplier or manufacturer on whom a sub-order

is placed by the Supplier.

Transfer of identification marks shall be undertaken prior tocutting to ensure m aintenance of identification on off-cuts.4. 4 The Supplier shall ensure that all alloy materials are segregated and stored in separatelyidentified locations to p revent the m ix up of m aterials of different alloy specifications or alloymaterial with carbon steel. Non ferro-magnetic materials shall be segregated at all times fromferro-magnetic materials.4 .5 PMI examination is subject to surveillance inspection by Owner/EIL/ TPIA.5.0 A C C E P T A BL E M E T H O D S F O R P M I5.1 The method used for PMI examination shall provide a quantitative determination of the alloyingelements like chromium, nickel, molybdenum or vanadium in Alloy Steel items.5 .2 Instruments or methods used for PMI examination shall be able to provide quantitative,recordable, elemental composition results for positive identification of alloying elementspresent.5.3 The acceptable instrum ents for alloy analyzer shall be either Portable X-Ray fluorescence or Optical Emission type each capable of verifying the percentage of alloy elements withinspecified range.5 .4 Chemical spot testing, magnets, alloy sorters and other methods using eddy current ortriboelectric testing methods are not acceptable for PMI examination.5 .5 The PMI instrument used shall have the sensitivity to detect the alloying elements in thespecified range.5 .6 All PMI instruments shall have been serviced within a 6 month period of the time of use toverify the suitab ility of batteries, sources etc., and the dat a of the last service shall be stated onthe PMI Report Form (Sample enclosed).5.7 Each analyzer must be calibrated according to the m anufacturer's specification at the beginningand end of each shift. Instrument m ust be checked against known standard for each alloy typeto be inspected during the shift.
