Metals and Alloys Ceramics and more The oscilloscope verifies resonance because the meter alone also reaches high points on harmonics. To us, complete customer satisfaction means: There were no books found for the applied search filters.

This allows for greater flexibility in testing. Other systems offer an oscilloscope connection. Geotest Instrument Corporation S. The test method may also be used to monitor the development of dynamic elastic modulus with increasing maturity of test specimens.
ASTM C Standard
No other units of x215 are included in this standard. Features of the HT Unit: Search Advanced Search Search Tips. USB memory stick connection Full spectrum data storage.
Even with customer service and price protection at the top of our complete customer satisfaction list, we know you want more. Nails, Spikes, and Staples. Land Use and Development. See 4 more pictures. Click here to download full list of books. 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. Different computed values for the dynamic modulus of elasticity may result from widely different resonant frequencies of specimens of different sizes and shapes of the same concrete.

This test method is intended 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. All claims must be made within 30 days of purchase. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. The oscilloscope confirms that peak reading on meter is actual resonance and not a harmonic.
The chassis measures 17x14x11″. Product knowledge and commitment to customer service guarantees that your order is processed the same day you place it. Geotest Catalog Request Catalog.
Resonant frequency can be determined by watching the voltmeter reach its highest point. When resonance occurs, the actual number is digitally displayed on the frequency counter.
The difference depends, in part, on the strength level of the concrete. Therefore, it is not advisable to compare results from specimens of different sizes or shapes. Our large selection of inventory lets us fill your order immediately and at a completion rate that is extremely high in our industry.
The value of the dynamic modulus of elasticity v215 by this test method will, in general, be greater than the static modulus of elasticity obtained by using Test Method C A very detailed instruction manual accompanies each sonometer.
No other resonant frequency system includes an oscilloscope despite being strongly recommended in ASTM C paragraph 4.
