RoHS stands for Reduction of Hazardous Substances and is an EU directive that prevents the use of certain substances in electronic products. It essentially directs to not keep certain chemicals in the product. The directive is popularly known as the “Lead Directive” among the engineers but in reality its not bound only with the lead but has rules for certain other chemicals as well.  The list of chemicals on which this regulation works are as follows: Lead (Pb) Mercury (Hg) Cadmium (Cd) Hexavalent Chromium (Cr6+) Polybrominated Biphenyls (PBB) Polybrominated Diphenyl Ethers (PBDE) Bis(2-Ethylhexyl)phthalate (DEHP) Benzyl butyl phthalate (BBP) Dibutyl phthalate (DBP) Diisobutyl phthalate (DIBP) All follow the limitation of a maximum of 0.1% The directive has been taken to be much more than only Lead Directive as for some electronic industries the product without Lead stays to be RoHS Complaint in nature. However, not all chemicals in the list are RoHS Complaint in nature. LDR or L...

The life cycle is a term that defines change from one form to another that happens sequentially. Every entity goes through a life cycle from its origin to its demise. Similarly, the software is also an entity with a development life cycle called the software development life cycle (SDLC). Just as if the development of software has different specific sequential steps, testing also follows a similar pattern. Life cycle testing or software  automotive life cycle testing  (SATLC) is a process of testing that consists of several specific testing procedures to be executed in a definite sequence to ensure a set quality standard of a product or software. There are many companies, which specifically provide life cycle testing services. Every organization has its different phases of the Software automotive life cycle testing, but the basis is of every life cycle testing remains the same. Eight phases of life cycle testing are as follows: Requirement phase: The scope of the testing is an...

In the Construction industry, your business reputation gets built on the quality of your work. The better the quality, the more renowned are your structures and that's how your brand name picks fame. Besides perhaps just for the reputation, quality output builds for you, construction material testing (CMT) is a critical process that helps you as a construction company to decide and plan. In delivering reliable and superior quality construction, companies need to abide by several legal and environmental compliances, which require optimal CMT. Testing Quality of Construction Material & their Composition Given the relevance and importance of the quality of construction materials, constructed companies deploy CMT for almost all of their raw building materials. Right from the testing the soil quality of the construction site, CMT also evaluates the quality of steel TMT bars, Aluminium, Cement, Concrete, Bricks, Aggregates, Admixture, Flyash, Masonry, Wood, Tiles, etc. Testing of cm ...

In this article, we will be discussing segregation, factors causing it, and different methods to avoid it . So, now the question arises what is segregation? The segregation of concrete is the failure of newly mixed concrete. Segregation is a term when the particles which are present in concrete, cement, sand, and their aggregates get separated from each other during handling and placement. It is usually caused by excessive vibration of cement In concrete technology , segregation is of three types:- Separation of Coarse aggregate from the concrete mixture, Separation of Cement paste from the concrete during the plastic stage Separation of water from the concrete mix (Which is also called as Bleeding in concrete) Some other factors causing segregation in concrete are: Transporting concrete mixtures for long distances. The poorly proportioned mixture, where the adequate matrix is not there to tie up the aggregates. Dropping concrete from more than 1m high can cause segregation. Vibratin...

Medical devices sterilization validation is a basic requirement for intrusive sterile medical products such as reusable surgical implants as well as implants. There are several methods of sterilization, and among them, the most commonly used methods are irradiation, heat, radiation, steam, and also ethylene oxide. Predetermined protocols are followed and there is a lot of focus on disinfection while following the procedures of proper sterilization.   All the bacteria, microbes such as bacteria or any other disease-causing microorganisms are removed or destroyed when the proper medical device sterilization methods are used. The method chosen for sterilizing will depend on the type of material with which the device has been made, the classification of the device, the availability of each sterilization method , and also the number of potential microorganisms that are involved.   Before sterilizing any instrument or device, it has to be cleaned properly. All the dirt, oi...

What Is Non-destructive Testing?  Non-destructive testing (NDT) also known as ‘positive testing’. As its name implies, non-destructive testing means testing of materials without destroying them. It is a kind of a testing approach in which the testing is performed to cover only the positive cases to confirm that the software behaves properly and returns the expected results as per the product requirement. It is one of the best courses to do if you want to get a high profile job in abroad or India in oil & gas, petroleum, aircraft, refinery, etc. It is commonly used in the area of aerospace engineering, mechanical engineering, civil engineering, electrical engineering, system engineering, and medicines. EXAMPLES OF DESTRUCTIVE TEST: Tensile test Compression test Shear test Hardness test Impact test Fatigue test Bending test Creep test Torsion test Chemical test, etc.   IMPORTANCE OD NDT: Save both time and money in product evaluation...
