Non-destructive testing is a wide group of analysis techniques used in science and part of Building Material Testing to evaluate the properties of a material, component, or system without causing damage. Since Non-destructive testing does not permanently alter the article being inspected, it is a highly valuable technique that can save both money and time in product evaluation, troubleshooting, and research.

 

What is Non-Destructive Testing?

​

Non Destructive Testing (NDT) is the process of inspecting or evaluating materials, components, or assemblies for irregularities, or differences in characteristics without destroying the serviceability of the part or system. In other words, when the test is completed the part can still be used.

 

In comparison to NDT, different tests are destructive in nature and are consequently carried out on a restricted wide variety of samples ("lot sampling"), rather than on the materials, components or assemblies simply being placed into service.

 

At present, the non-destructive tests are used in manufacturing, fabrication, and in-service assessments to make sure product solidarity and reliability, govern production strategies, decrease manufacturing prices, and maintain a uniform quality level. During construction, NDT is used to ensure the quality of materials and corresponding processes during the fabrication and erection phases, and in-service NDT inspections are used to make sure that the products in use continue to have the integrity to ensure their utilization and the safety of the public.

 

WHY USE NDT?

​

Here are the topmost reasons Non-Destructive Tests are used by so many organizations around the world:

​

• Economical. The clearest-cut answer to this question is that NDT is more appealing than destructive testing because it permits the material or object being examined to survive the assessment unharmed, thus saving money and resources.

​

• Safety. NDT is also fascinating because almost all NDT techniques (except radiographic testing) are harmless to people.

​

• Effectiveness. NDT methods allow for the thorough and relatively quick evaluation of assets, which can be crucial for ensuring continued safety and performance on a job site.

​

• Accuracy. NDT techniques have been proven on the mark and forecasted, both qualities you want when it comes to maintenance procedures meant to make sure the safety of personnel and the longevity of equipment.

​

We the Ace Test House have highly trained personnel and branded tools to perform the Testing, here are the types of NDT:-

​

• Pile Integrity Test

• Ultrasonic Pulse Velocity Test

• Radiography Test

• Rebound Hammer Test

• Magnetic Particle Inspection or Liquid Penetration Test

• Half Cell Potential

​

 

What is Rebound Hammer Test?

​

Schmidt Hammer or Rebound Hammer Test is a Non-destructive testing technique of concrete that offers a handy and fast indication of the compressive strength of the concrete structure such as beams and columns.

​

​

Objectives of Rebound Hammer Test.....

​

As per the Indian Standard code IS: 13311(2)-1992, the Rebound Hammer or Schmidt Hammer test has the following objectives:

 

• To assess the compressive strength of the concrete by relating the rebound index and the compressive strength.

• To ensure the conformity of the concrete.

• To ensure the quality of the concrete based on the standard specifications.

• To ensure one concrete element with another in terms of quality.

​

​

Ultrasonic Pulse Velocity Test

​

Ultrasonic Pulse Velocity test on concrete is also a non-destructive test to derive the homogeneity and robustness of the concrete. The evaluation of pulse velocity can be used for the determination of the consistency of concrete, the presence of cracks or voids, changes in properties with time, and the determination of dynamic physical properties. With this ultrasonic test on concrete, the following can be assessed:

​

• Qualitative analysis of the strength of concrete, its gradation in different locations of structural members, and plotting the same.

• Any irregularity in cross-section like cracks covers concrete delamination etc.

• Depth of surface cracks

​

Half-Cell Potential Test

​

Corrosion goes with nature and occurs when a reinforced structure is exposed to atmoshpheric elements like carbon dioxide or chloride, which can penetrate the concrete all the way to the steel reinforcement. This can have very serious longevity and safety consequences, which is why the Half Cell Potential test is important to monitor corrosion using an accurate and trusted method.

 

The half-cell potential test is the only Standard Test Method for Corrosion Potentials of Uncoated Reinforcing Steel in Concrete. It is used to assess the probability of corrosion within the rebar in reinforced concrete structures.

Non-Destructive Testing Lab in Delhi

Non Destructive testing or NDT refers to diverse inspection methods - allowing inspectors or concerned persons to evaluate and collect data about a material, system, or component without permanently altering it. Such types of testing processes are done in the world-class non destructive testing lab in Delhi. Each of testing has its own advantages and limitations. Such types of tests are divided into different categories:

•    Ultrasonic Testing (UT)
•    Radiographic Testing (RT)
•    Electromagnetic Testing (ET)
•    Magnetic Particle Testing (MT)
•    Liquid Penetrate Testing (PT)
•    Visual Testing
