CDG conduct impact protection test in Mumbai, India. CDG is an accredited testing services in India. Impact testing is testing an object's ability to resist high-rate loading. An impact test is a test for determining the energy absorbed in fracturing a test piece at high velocity. Most of us think of it as one object striking another object at a relatively high speed. WHY IS IMPACT TESTING IMPORTANT? Impact resistance is one of the most important properties for a part designer to consider, and without question, the most difficult to quantify. The impact resistance of a part is, in many applications, a critical measure of service life. More importantly these days, it involves the perplexing problem of product safety and liability. One must determine: The impact energies the part can be expected to see in its lifetime. The type of impact that will deliver that energy, and then Select a material that will resist such assaults over the projected life span Molded-in stresses, polymer orientation, weak spots (e.g. weld lines or gate areas), and part geometry will affect impact performance. Impact properties also change when additives, e.g. coloring agents, are added to plastics. DUCTILE VS. BRITTLE, Most real world impacts are biaxial rather than unidirectional. Further complication is offered by the choice of failure modes: ductile or brittle. Brittle materials take little energy to start a crack, little more to propagate it to a shattering climax. Other materials possess ductility to varying degrees. Highly ductile materials fail by puncture in drop weight testing and require a high energy load to initiate and propagate the crack. Many materials are capable of either ductile or brittle failure, depending upon the type of test and rate and temperature conditions. They possess a ductile/brittle transition that actually shifts according to these variables. Please contact us on +919643077962 Visit our website https://www.cdginspection.com/

CDG conduct impact protection test in Delhi, India. CDG is an accredited testing services in India. Regarding the impact protection (IK) rating system, standards IEC 62262: 2002 and IEC 60068-2-75: 1997 have been published for electrical equipment. In these standards, the degrees of protection provided by the enclosures against external mechanical impacts are shown as follows: IK00 = Not protected, IK01 = protected against 0.14 joule impact (56 kg mass impact falling from 0.25 mm), IK02 = protected against 0,2 joule impact (80 kg mass impact falling from 0.25 mm), IK03 = protected against 0,35 joule impact (140 kg mass impact falling from 0.25 mm), IK04 = protected against 0,5 joule impact (200 kg mass impact falling from 0.25 mm), IK05 = protected against 0,7 joule impact (280 kg mass impact falling from 0.25 mm), IK06 = protected against 1 joule impact (400 kg mass impact falling from 0.25 mm), IK07 = protected against 2 joule impact (400 kg mass impact falling from 0.50 mm), IK08 = protected against 5 joule impact. It is equivalent to the 300 kg mass effect falling from 1.70 mm. IK09 = protected against 10 joule impact (200 kg mass impact falling from 5 mm), IK10 = Protected against 20 joule impact (400 kg mass impact falling from 5 mm), Within the scope of electrical test laboratory services, CDG also provides IK impact protection test services. Thanks to these services, businesses receive more effective, high-performance and quality testing services and provide safe, fast and uninterrupted service to their customers.

CDG conduct impact protection test in Pune, India. CDG is an accredited testing services in India. Impact tests are used in studying the toughness of material. A material's toughness is a factor of its ability to absorb energy during plastic deformation. Brittle materials have low toughness as a result of the small amount of plastic deformation that they can endure. The impact value of a material can also change with temperature. Generally, at lower temperatures, the impact energy of a material is decreased. The size of the specimen may also affect the value of the Izod impact test because it may allow a different number of imperfections in the material, which can act as stress risers and lower the impact energy. IK ratings are defined as IKXX, where “XX” is a number from 00 to 10 indicating the degrees of protection provided by enclosures (including luminaires) against external mechanical impacts. The different IK ratings relate to the ability of an enclosure to resist impact energy levels measured in joules (J). EN/IEC 62262 specifies how the enclosure must be mounted for testing, the atmospheric conditions required, the quantity and distribution of the test impacts and the impact hammer to be used for each level of IK rating. Characteristic numbers of IK codes and their definitions, Each set of characteristic numbers represents a collision energy value, the correspondence between the IK code and its corresponding collision energy. In the IEC62262 protection class code, the IK code indicates the protection level of the shell against harmful mechanical collisions to the outside world, and the characteristic number combinations are: 01 to 10, i.e.: IK01, IK02, IK03, IK04, IK05, IK06, IK07, IK08, IK09 and IK10, collision energy //J a 0.14 0. 2 0.35 0.5 0. 7 1 2 5 10 20 In these 10 levels, there are two groups of tests according to different levels of test levels: the first group is spring impact hammer test from IK01, IK02 to IK06, this group test has a smaller energy (from 0.14J to 1J); The other group is the pendulum test from IK07, IK08 to IK10, which tests with larger energies (ranging from 2J to 20J).
