2 Topics for Discussion Code Allotment Component Approval Procedure Component Coding Scheme Component Data Base
3 CODE ALLOTMENT - STUDY OF COMPONENT DRAWING AND TECHNICAL DATA PREPARATION OF DRAWING & SPECIFICATION INPUT TO DATABASE CODE REQUEST FROM R & D Code Allotment
4 Component Approval Procedure Registration of Component Vendor Registration of Component Vendor Collect and scrutinise technical literature Collect and scrutinise technical literature Electrical,Mechanical and Environmental tests Electrical,Mechanical and Environmental tests Vendor Assessment Vendor Assessment Clearance for Educational order Clearance for Educational order Inclusion in CDB Inclusion in CDB Qualification Approval after satisfactory performance Qualification Approval after satisfactory performance
5 INTERACTION WITH VENDORS & PROCUREMENT OF SAMPLES EVALUATION OF SAMPLES AS PER SPECIFICATION ARE RESULTS OK? COMPONENT APPROVAL GROUP ACCORD APPROVAL INPUT TO DATABASE USAGE OF DATABASE VENDOR REGISTRATION AND ASSESSMENT COMPONENT APPROVAL COMMITTEE R & D CONCURRENCE NON- CONFORMANCE CORRECTIVE ACTION NO YES Component Approval Procedure
6 COMPONENT APPROVAL PROCEDURE PROCESS STEPS 1. R & D Project Engineers shall identify the components for which 15 digit code is not available in Component Database (CDB) and need to be used in their designs and send formal request to Component Approval Group for allotment of codes.
7 COMPONENT APPROVAL PROCEDURE 2. After scrutiny as per guidelines provided in Coding Scheme, 15 digit code will be allotted and draft drawing is prepared and sent to project engineer for concurrence. A final drawing is prepared after the Project Engineer’s concurrence and approval is accorded and included in CDB.
8 COMPONENT APPROVAL PROCEDURE 3.Sample components are received from Vendors / Purchase / Production Planning etc. by Component Approval Group and these components are sent to various labs for test & inspection and the Division concerned for Evaluation e.g. Test Set, IGI and Production Line to check assembly suitability etc. After the tests are completed, the reports are received by CAG for scrutiny.
9 COMPONENT APPROVAL PROCEDURE For components where expertise is not available with Component Approval Group, test results are sent to R & D for their analysis and concurrence. In specific cases R & D conducts tests on components and provide results along with their recommendation to Component Approval Group.
10 COMPONENT APPROVAL PROCEDURE 4. Vendor assessment is carried out as per Vendor Development Manual CL / VDC / 001. Action is taken to put up appropriate cases to Component Approval Committee for approval. In the case of non-conformance, the matter is taken up with the vendor / agents.
11 COMPONENT APPROVAL PROCEDURE The Component Approval Committee comprises Component Approval Group Head as Secretary Component Approval Group Head as Secretary One Member from R & D One Member from R & D One Member from QA. One Member from QA. This committee approves the components from new indigenous source which do not have approval by LCSO / CACT.
12 COMPONENT APPROVAL PROCEDURE Alternate results submitted by vendor from recognized test labs like ETDC, ERTL, BEL or CQAL and approvals issued by recognized agencies like LCSO or CACT are scrutinized and if found adequate for our requirement, are considered for approval.
13 COMPONENT APPROVAL PROCEDURE 5. In case of components for Defence Production, approval of LCSO only is considered and CDB updated accordingly. After satisfying all approval norms, the source is introduced in Component Data Base. 6. Initially Educational status is awarded. On successful completion of Educational Orders, Qualification status is awarded
14 COMPONENT APPROVAL PROCEDURE 7.In exigencies, Head of Component Approval is empowered to approve a code (Limited approval) on satisfactory performance in production line / functional tests in actual circuit / feedback on earlier satisfactory acceptance in IGI / approval of similar type of component in the same family of a manufacturer’s product range.
15 COMPONENT APPROVAL PROCEDURE 8. In case of foreign vendors, approval is granted based on the scrutiny of track record / document. Department Head is empowered to approve on a case to case basis. 9. In case of collaborated projects, MOU guidelines are followed.
