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.
GrindoSonic HT System – HT-SYSTEM
Therefore, it is not advisable to compare results from specimens of different sizes or shapes. Features of the HT Unit: No items in cart.
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.
F Standard Specification for Driven Fasteners: All other units use accelerometers which require intimate contact c2215 the test specimen. The oscilloscope verifies resonance because the meter alone also reaches high points on harmonics.
Complete refund or credit will be astmm for unused and unmarked items returned ashm 10 days of receipt. Please login to your authorized staff account to use this feature. Nails, Spikes, and Staples. The chassis measures 17x14x11″. Significance and Use This test method is wstm 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.
Satisfaction Atm – If for any reason our products do not meet your expectations, return them. C Rapid Freeze-Thaw Apparatus. Search book title Enter keywords for book title search. The test method may also be used to monitor the development of dynamic elastic modulus with increasing maturity of test specimens.
If you like to setup a quick demo, let us know at support madcad. Process control Number of programs 5 with controller unit B standard Grindosonic Number of Elevated segments 4 with B standard Grindosonic Optional: 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.

E-Meter for Flexural Resonance of Concrete
Even with customer service and price protection at the top of our complete customer satisfaction aastm, we know you want more. Look through our website. The apparatus consists essentially of a driver and pickup circuit. E Terminology for Nondestructive Examinations. The value of the dynamic modulus of elasticity obtained by this test method will, in general, be greater than the static modulus of elasticity obtained by using Test Method C Ease of use measurement system Connection to an High Temperature oven is possible Trigger asym adjustable Option: 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.
Remember me for one month. No other resonant frequency system includes an oscilloscope despite being strongly recommended in ASTM C paragraph 4. When resonance occurs, the actual number is digitally displayed on the frequency counter. The conditions of manufacture, the moisture content, and other characteristics of the test specimens see section on Test Specimens materially influence the results obtained.

The original PCA design has been modified by changing to solid state circuitry and addition of a built-in cathode ray oscilloscope.
