ASTM STANDARDS FOR NON-DISTRUCTIVE TESTING

• 

  ASTM D6938 - Standard Test Methods for In-Place Density and Water Content of Soil and Soil-Aggregate by Nuclear Methods (Shallow Depth)

  The Nuclear Moisture Density device (or Nuclear Gauge) is specifically designed to measure the moisture and density of soils, aggregates, cement, and lime treated materials, and to measure the density of asphalt concrete. Nuclear Moisture Density Gauge complies with all pertinent standards: ASTM D6938, D2950, C1040 and AASHTO T310 and is calibrated by the Five-block calibration method

• 

  ASTM D6432-19 - Standard Guide for Using the Surface Ground Penetrating Radar Method for Subsurface Investigation

  Ground Penetrating Radar (GPR) is most often employed as a technique that uses high-frequency electromagnetic (EM) waves (from 10 to 7000 MHz) to acquire subsurface information. GPR detects changes in EM properties (dielectric permittivity, conductivity, and magnetic permeability), that in a geologic setting, are a function of soil and rock material, water content, and bulk density.

• 

  ASTM C597-16 - Standard Test Method for Pulse Velocity Through Concrete

  Ultrasonic Pulse Velocity (UPV) testing is used to determine the integrity of structural concrete by measuring the speed and attenuation of an ultrasonic wave passing along a specific test path in the element being tested. Using multiple test paths allows the size and rough shape of a defect area to be defined geometrically.

• 

  ASTM C805 / C805M-18 - Standard Test Method for Rebound Number of Hardened Concrete

  Rebound Hammer test is a Non-destructive testing method of concrete which provide a convenient and rapid indication of the compressive strength of the concrete. The rebound hammer is also called as Schmidt hammer that consist of a spring controlled mass that slides on a plunger within a tubular housing.

• 

  ASTM D4541-17 - Standard Test Method for Pull-Off Strength of Coatings Using Portable Adhesion Testers

  Pull-Off Adhesion: simple to use, quantitative range giving a definitive adhesion value, ideal for the laboratory or field on flat or curved substrate applications. Tensile Dollies (or stubs) are glued to the coating and, when the adhesive has cured, the force required to pull the coating off the surface is measured.

• 

  ASTM C1074-98 - Estimating concrete strength by the maturity meter method.

  These units utilize inexpensive, disposable, T-type thermocouple wire with quick-connect jacks, which can be embedded directly into a concrete structure to measure temperature at timed intervals. These readings can then be used to document the maturity process.

• 

  ASTM F2659-10 - Standard Guide for Preliminary Evaluation of Comparative Moisture Condition of Concrete, Gypsum Cement and Other Floor Slabs and Screeds Using a Non-Destructive Electronic Moisture Meter

  Moisture in concrete floor slabs affects the performance of flooring systems such as resilient, wood, and textile floor coverings and coatings. Manufacturers of such systems generally require moisture testing be performed before installation of coverings on floor slabs and screeds.
