Testing - Ferro Scanning of Column, Beam and Slab for Rebar Detection:

Wan test has substantial experience in using Ferro scanning equipment and translating scanned images. Having this type of information available is essential to our clients who plan to drill, cut or core through existing concrete structures to ensure the integrity of the structure is maintained and also the safety of the operator.

By keeping up to date with the latest technology available you can be sure that our teams will have the correct equipment for the job saving you time and money when it comes to concrete scanning. The results from the Ferro scans can usually be viewed on site using real time technology which provides designers and engineers with the information they need when they need it. Our Ferro scanning service can be used to for many applications.

Examples include:

  • Determining the concrete cover of existing slabs, walls, columns, etc.
  • Determining location and configuration of steel reinforcement
  • Detailing an image of a concrete slab to avoid rebar or electrical conduit prior to coring activities
  • Identifying the location of post-tension cables
  • Determining thickness of concrete slabs
  • Thermal, Insulation & Earth test

Testing - Rebar test (Tensile strength test):

Rebar test (Tensile strength test):

Tensile Testing of Metals is a destructive test process that provides information about the tensile strength, yield strength and ductility of the material. Laboratory Testing Inc. near Philadelphia, PA in the USA performs the tensile test in accordance with industry standards and specifications, including ASTM tensile test methods. This process is also known as a tensile strength test or tension test.

Range of tensile testing capabilities:

  • Wedge & axial tensile.
  • Full-size yield strength of fasteners.
  • Testing of machined specimens.
  • Full-size tubing.
  • Full-size rebar.
  • Elevated temperature tensile testing.
  • Tensile testing of welds and castings.

Test methods/ Specifications:

  • ASTM A370
  • ASTM B557
  • ASTM D638
  • ASTM E8
  • ASTM E21
  • EN 2002-1
  • EN 10002-1

  • ISO 6892-1

Fastener Testing:

  • ASTM A962
  • ASTM F606
  • ASTM F835
  • ISO 898-1
  • ISO 898-2
  • NASM-1312-8 (Formerly MIL-STD-1312-8)
  • SAE J429
  • SAE J995

The Tensile strength test process:

Material strength testing, using the tensile or tension test method, involves applying an ever-increasing load to a test sample up to the point of failure. The process creates a stress/strain curve showing how the material reacts throughout the tensile test. The data generated during tensile testing is used to determine mechanical properties of materials and provides the following quantitative measurements:

  • Tensile strength, also known as Ultimate Tensile Strength (UTS), is the maximum tensile stress carried by the specimen, defined as the maximum load divided by the original cross-sectional area of the test sample.
  • Yield strength is the stress at which time permanent (plastic) deformation or yielding is observed to begin.
  • Ductility measurements are typically elongation, defined as the strain at, or after, the point of fracture, and reduction of area after the fracture of the test sample.

Testing - Thermal, Insulation & Earth test:

Thermo graphic testing:
Thermo graphic testing is a non-destructive test method that may be used to detect poor connections, unbalanced loads, deteriorated insulation, or other potential problems in energized electrical components. These problems may lead to excess power use, increased maintenance costs, or catastrophic equipment failure resulting in unscheduled service interruptions, equipment damage, or other problems.

Thermo graphic testing of electrical equipment:
A useful addition to a preventative maintenance program, Care labs can carry out a thermo graphic scan and Thermo graphic Testing of all areas likely to be running too hot or too cold. The number one application for infrared thermograph globally is electrical applications.80% of electrical faults are not visible. Thermal imaging is the technique for making invisible infrared radiation visible. Thermal images capture fully radiometric infrared images using IR-Fusion® technology, photographic images and will be included in a report.

How does thermography work:
Thermo graphic also called infrared inspection is based upon the sensing of heat emitted from the surface of an object in the form of infrared radiation. Test instruments are used to detect and convert the infrared radiation into either a temperature value or a thermal image, which can be used to assess the thermal condition of the object at the time of measurement. An infrared camera is one common type of an infrared thermal imaging device.
