The apparatus consists essentially of a driver and pickup circuit.
Today, some 12, ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence. Click to order atsm GrindoSonic MK7 separately. With the Geotest pickup and driver mounted on portable stands, it is not necessary to use a test bench, which is mandatory on other apparatus.

F Standard Specification for Driven Fasteners: Significance and Use This test method is qstm primarily for detecting significant changes in the dynamic modulus of elasticity of laboratory or field test specimens that are undergoing exposure to weathering or other types of potentially deteriorating influences. Our extensive inventory is yet another way to keep you satisfied. The test method may also be used to monitor the development of dynamic elastic modulus with increasing maturity of test specimens.

Our astk selection of inventory lets us fill your order immediately and at a completion rate that is extremely high in our industry. Product knowledge and commitment to customer service guarantees that your order is processed the same day you place it. Geotest Instrument Corporation S. The original PCA design asm been modified by changing to solid state circuitry and addition of a built-in cathode ray oscilloscope.
Even with customer service and price protection at the top of our complete customer satisfaction list, we know you want more. Remember me for one month. There were no books found for the applied search filters.
All other units use c251 which require intimate contact with the test specimen. Other systems offer an oscilloscope connection. The oscilloscope verifies resonance because the meter alone also reaches high points on harmonics.
This allows for greater flexibility in testing. The oscilloscope confirms asm peak reading on meter is actual resonance and not a harmonic. No other units of measurement are included in this standard. See 4 more pictures. A very detailed instruction manual accompanies each sonometer. To us, complete customer satisfaction means: Advanced Search Search Tips.

This test method is intended primarily for detecting significant changes in the dynamic atm of elasticity of laboratory or field test specimens that are undergoing exposure to weathering or other types of potentially deteriorating influences. Nails, Spikes, and Staples. The conditions of manufacture, the moisture content, and other characteristics of the test specimens see section on Test Specimens materially influence the results obtained. This apparatus closely follows design parameters set up over 40 years ago by the Portland Cement Association research laboratories.
