Certainly it is important that you carry out regular visual inspections of all the wires that connect your appliances to the mains electrical supply. If you notice any of these have become damaged or frayed then you should be considering disconnecting them from the mains power supply.
The other way of determining if the equipment is still safe to operate is to use a PAT tester. These are hand held electric safety testing devices that you can purchase locally or online. There are several different makes and models available and all come with a variety of different features. Which one you choose of course depends on the kinds of electrical equipment that needs testing along with how much you can afford to spend.
However the type of PAT tester you should be choosing is one that carries out earth bond testing as well as 550v insulation testing. Those with these types of features will immediately provide you with a warning if the electrical equipment is going to cause harm because it isn’t earthed correctly or the insulation of the equipment has deteriorated.
Biomedicals, metals, plastics, spring, wood, electronic and electrical components etc are some of the many materials that are tested before being used in various applications. Wood testing ensures a simple and reliable way to determine the strength and deformation properties of wood. Bend testing is particularly useful to test its strength because wood is frequently used in the form of beams where resistance to bending is an important parameter.
