Lots of planning goes into the finished goods that are available to consumers every day. From the smallest smart watch to the biggest storage tank, every item goes through a design process that takes into account its function and alternative uses.
The plans do not stop with the design, however. Stress testing is also a big part of the manufacturing stage. Before a product goes into the market, developers have to make sure the output they provide will not embarrass their brand. No one will ever know what went wrong with Samsung’s product testing that led to the recall of Samsung Galaxy Note7 smartphones, but one thing is for sure: no one wants that to happen to his or her company.
Here are three factors that affect product reliability, which manufacturers must pay close attention to:
Most products are used under normal temperature ranges, but a traveler would want to be sure that his or her smartphone will not stop working when he heads to a polar region. The same goes for batteries, tires, and car engines, which may be subject to extremely high temperatures even in normal working environments. Manufacturers cannot skip stress testing, say HASS experts, because doing so may lead to accidents and bad publicity for their brand.
Any business wants to minimize the production cost while improving the quality of its product, which means that at a certain point, it might change the processes or materials it uses in the search for a system that will be more cost effective. It is wrong to assume, however, that the replacement material will be exactly like the original. Replacing a reliable material for cost savings may come with some drawbacks, which the company may not be able to uncover without the proper accelerated stress testing procedures.
Number of Welded Joints
Joints, regardless of how strongly welded they are, are the weak spots in a storage tank, for example. These joints should be able to withstand the minimum amount of stress exerted upon them by the material they are supposed to store. Tanks go through stress testing to make sure that the welded joints will not split open and compromise the material being stored, and will keep everyone around the tank safe.
Manufacturers do not run out of wonderful products to launch in the market every day, but whether these products will be useful in the long term or not is something only time will tell. Meanwhile, it is important for these products to undergo several tests based on known reliability metrics to keep them useful, efficient and safe for everyone who will use them.
