INTERN AL LABORATORY SCOPE

2.0    SCOPE:

This procedurę is to define the Intemal Laboratory Scope

3.0    QUALITY PROCEDURĘ:

Heat Treat Laboratory Scope - Ref. Clause 7.6J.1 Technical Capability:

Feature measured Crystal grain size Fiber flow Micrastructure	Rance 50,100,200,400 &1000X magnilication	Eauioment Olympus PME-3 Metal lo grap h
Surface hardness	HRB & HRC scales	Mitutoyo ARK-600
Core hardness	convert to all scales	Mitutoyo ATK-F2000 Macro-hardness testers
Case Depth	Hvickers	Leco 300AT
Indirect surface hardness	convert to all scales	Futurę Tech FM700 Micro-hardness testers

Ali testing equipment and performed tests are in compliance with applicable ASTM stan dar ds. Reference standards are as follows:

•    ASTM E-112 Determine Grain Size

•    ASTM E-407 Microetching Metals and Alloys

•    ASTM E3-01 Preparation of Metal k) grap hic Specimens

•    ASTM E92-82 Vickers Hardness of Metallic Materials

•    ASTM El40-02 Conversion Tables

•    ASTM E2014-99 Metallographic Laboratory Safety

Calibrations and Master Yerification:

Annual calibrations and daily master verifications are performed as specified in:

•    ASTM E-18 for Rockwell testers

•    ASTM E-384 for microvickers testers

•    ASTM Er 1951 for microscopes

Ali hardness measuring devices are verified daily by the use of N.I.S.T. traceable standard blocks. Daily verifications are logged in Master Verification Log Book in Heat Treat department.

M.S.C. Heat Treat laboratory uses Leco Corporation for annual calibration of all optical measuring devices.

Leco optical service calibrations are accredited to ISO 17025 by A2LA.Calibration records and laboratory scope for e.\temal bb are kept on file in the Gage Control section of Quality Control.

Test Methods and Specifications:

All characteristics tested have guidelines and specifications provided in tlie customer dra win gs located in tlie Quality Control area and listed on Operator Process Instructions.
