Proficiency Testing Provider

Deep Metallurgical Services (DMS) is an accredited Proficiency Testing Provider (PTP) by the renowned National Accreditation Board for Testing and Calibration Laboratory (NABL), India according to ISO17043-2010 vide certificate no PC1045 in metals and alloys. DMS is accredited for ninety-seven measurands in chemical analysis that include chemical analysis of plain carbon and low alloy steel, stainless steel, tool steel, cast iron, aluminum alloys, copper alloys, and nickel alloys.DMS is also accredited for thirty-eight measurands in mechanical disciplines covering all parameters of tensile properties, macro, and micro Vickers hardness, Rockwell C and B Scale, Brinell Hardness Number (HBW) 10mm and 2.5mm Tungsten ball, Charpy Impact at room temperature and subzero temperature, transverse weld tensile properties, guided weld side bend; flattening and flaring test.

In metallography and microstructure analysis, DMS is also accredited for twenty-one parameters that include volume fraction of phases covering delta ferrite, pearlite and ferrite, austenite, and ferrite grain size, graphite form, and distribution; depth of decarburization, case depth, and coating thickness; inclusion rating, the macrostructure of weld and classification of structure.In corrosion test parameters, DMS is further accredited for classification of etched structure of stainless steel by ASTM A262 Method A and duplex stainless steel by ASTM A923 Method A, susceptibility to corrosion in stainless steel as per ASTM A262 Practice B, C & E ( or equivalent ISO methods), resistance to pitting in duplex stainless steel by ASTM G48, Method A or ISO 17781, detecting intermetallic phase in duplex stainless steel by ASTM A923 Method C and intergranular corrosion in nickel alloys by ASTM G 28. Presently there are fifty-four ongoing PT programs. All programs are either simultaneous quantitativeor simultaneous qualitative. All PT programs including metallography and microstructure parameters are based on the PT samples and no images are provided for any of the PT programs. The participating laboratory is instructed to carry out tests as per any standard method such as ASTM, ISO, IS, or any validated method using proficiency testing samples utilizing their own equipment and manpower. PT programs have been designed to record the performance of a participant in routine test parameters. The participating laboratory would certainly benefit from the elaborate reporting covering all clauses of ISO17043-2010. The participants can compare their own results with results from other participants keeping confidentiality as per ISO17043-2010.PT samples are produced by DMS with traceability to the SI unit. The homogeneity and stability assessment, statistical data analysis, performance evaluation, and reporting are performed by DMS.The management of DMS as PTP is composed of a PTP testing program committee chaired by an MD, a metallurgist having wide experience in research and development, a program manager, a quality manager, a statistician, and technical advisors.

DMS has now launched unique 54 (fifty-four) Proficiency Testing (PT) programs in corrosion, metallography, mechanical, and chemical test parameters. DMS provides proficiency testing samples like reference material and all samples are produced by DMS.DMS offers cost-effective PT programs, with discounts on PT fees, packing, and forwarding charges.
