TITLE: STS Calibration GENERAL Procedure purpoSE To define the procedure of calibration in STS Plant. SCOPE This procedure is eligible for all the measuring testing equipment and manufacturing equipment with measuring testing function. REFERENCE DOCUMENTS Calibration Procedure – 0076600 Quality Assurance Requirements For Measuring Equipment – ISO 10012-1 Quality System Requirements –ISO/TS 16949 General Requirements For The Competence Of Testing And Calibration Laboratories – ISO/IEC 17025 DEFINITIONS Calibration – A set of operations that establish, under specified conditions, the relationship between values indicated by a measuring instrument or measuring system, and values represented by a reference material, or the corresponding standard, or known values derived from the standard. Measuring testing equipment - All devices used to measure, gauge, test, inspect or otherwise examine items to determine compliance with specifications. Primary standards (reference) - Standards of the highest metrological quality from which measurements made are derived. Secondary standards (transfer) - Standards used as an intermediary to compare standards. Working standards - standards that is used routinely to calibrate or check material measures, measuring instruments of reference materials. Traceability - Property of the result of a measurement or the value of a standard whereby it can be related to stated references, usually national or international standard, through an unbroken chain of comparisons all having stated uncertainties. ECN: Equipment Control Number GENERAL Calibration Laboratory (hereafter refers to Cal Lab) should maintain calibration database of all measuring and testing equipment. Each operation organization maintains database for manufacturing equipment. Calibration Scope Category: - Manufacturing equipment with measuring testing function - IPC (In Process Control) equipment - Measuring meter / instrument - Standard Ownership Scope Report Label
