All sets meet or exceed Fed. Spec. ASME B89.1.9-2002 Grade : Economy Sets calibrated to meet or exceed federal specification GGG-G-15C, Grade : B Surface finish 4.1 millions. All calibration conforms to:MIL-STD 45662A, GGG-G-15C, ISO/IEC 17025 Accredited, ISO 9000, 10012-1, ANSI-NCSL Z540-1, ISO GUIDE 25 Certified Mirror polished surfaces provide superior wringing characteristics Guaranteed Accuracy of Flatness, and Parallelism Excellent Finish and Wringing Characteristics The interior separator is made out of plastic, therefore it will guarantee the gage blocks won't get wet or rusty All sets are supplied in deluxe fitted wood case The inspection certificate specifies the deviation of each individual block from its nominal length. Gage blocks are commonly used to calibrate fixtures and precision instruments in workshop, inspection, and dimensional metrology applications, to inspect tools such as mounting tools, cutters, fixtures, and mechanical parts, and in the gage manufacturing process itself. Grade B gage blocks are commonly used in workshops for calibrating and inspecting mounting tools and cutters New Grade ASME B89.1.9-2002 Nominal Size Tolerances (in Millionths of an inch) 0 AS-1 AS-2 Economy Thru .050 +/-6 +/-12 +/-24 +/-50 Thru .400 +/-5 +/-8 +/-18 +/-50 Thru 1" +/-6 +/-12 +/-24 +/-50 Thru 2" +/-8 +/-16 +/-32 +/-50 Thru 3" +/-10 +/-20 +/-40 +/-50 Thru 4" +/-12 +/-24 +/-48 +/-50 Old Grade GGG-G-15C Nominal Size Tolerances (in Millionths of an inch) Grade B Thru .050 +/-50 Thru .400 +/-50 Thru 1" +/-50 Thru 2" +/-50 Thru 3" +/-50 Thru 4" +/-50 Compare Chart of New and Old Standard Grade and Application Workshop use->Mounting tools and cutters->Grade AS-1 or AS-2 Workshop use->Manufacturing gages->Grade 0 or AS-1 Workshop use->Calibrating instruments->Grade 0 or AS-1 Inspection use->Inspecting mechanical parts, tools, etc.->Grade 0 or AS-1 Inspection use->Checking the accuracy of gages->Grade 0 Inspection use->Calibrating instruments->Grade 0 Grade AS-1: These gage blocks are intended for shop floor use to set and calibrate fixtures as well as precision instruments. Grade 0: This grade is used within an inspection area to verify the accuracy of plug and snap gages as well as for setting electronic measuring devices. Grade Economy Steel Rectangle Inch Gage Block Set includes a set of Rectangle-shaped, high-carbon, high-chrome steel gage blocks with nominal length engraved in inches on each, and is supplied with a SHARS inspection certificate that states that the blocks meet American Society of Mechanical Engineers (ASME) B89.1.9-2002 Grade Economy standard for flatness, length, parallelism, and surface finish. High-carbon, high-chrome steel has a high hardness for minimum deterioration, and is selected for its wear-resistance. These gage blocks have aRectangle base for accurate wringing, to attain a height reference standard, and for the ability to make a dedicated inspection jig. The nominal length of each block is measured in inches, and is indicated with laser-etched, black characters. An identification number is laser-etched on each block for traceability. The set includes an inspection certificate [National Institute of Standards in Engineering (NIST)-traceable] that the blocks meets ASME B89.1.9-2002 standard for flatness, length, parallelism, and surface finish.Gage blocks (also called gauge blocks, Hoke blocks, Jo blocks, slip gages, and Johansson gages) are blocks used to calibrate measuring equipment and to standardize the measurement of length in manufacturing industries. They are commonly made of precision-ground steel, ceramic, or carbide material, and have a Rectangle or rectangular base. Each block has a unique identification number. Length is in inch or millimeter measurement. Gage blocks can be wrung together to create a required length. Wringing is the process of lapping blocks together with a small amount of oil. They are standardized by grade, which refers to the tolerance or deviation of an individual block from its nominal length. Gage block grades are defined for flatness, length, parallelism and surface finish. Some grades of gage blocks meet standards such as ASME, Association for Iron and Steel (AIST), and International Organization for Standards (ISO). Application and required level of accuracy dictate which grade of gage block should be used. Both a certificate of inspection and a calibration certificate specify the deviation from the nominal length. Also see the great deal on Gage Block with Certificates at My Ebay Store
