A manufacturer is responsible for creating a durable and tough product before it launches this new item in the market. The research and development (design) team, together with the quality group, conducts a series of testing to ensure that the product is all set for full production. Examples of these standard tests are the price test, dynamic test, construction test, human test and the drop test. The drop test or impact test is a simple technique used to measure the durability of a material or a part by making it fall freely from a certain height into a surface, under conditions that have been prescribed earlier. This is one of the easiest tests that have been done to different types of products. Just like other tests, the advantage of doing the drop test is to prevent future problems and complaints which will have a corresponding expense to be incurred.
The procedure on how to do a drop test is as easy as measuring the height you intend to use as a basis, and then drop the object without much force. You will want to see the impact of natural gravity to effect in the object. Once the object is dropped, your team will determine the following:
- Is the item already broken to the point that it cannot be used?
- Are some parts broken, but the item can still serve its purpose?
- What are the strong and weak parts of the equipment?
- If its height is adjusted from where it started to fall, will the impact change?
- What are the other observations you can see as the product falls? Is there a side which always lands first?
Once these questions are answered, the drop paper will be your test results. The next step is for you to analyze if the product can move to the next testing or if it discontinues the process. Once you find that there is a potential in this item, it can be said that it passed the drop test. The next step is to improve the product. You can add certain components that will act as an energy absorber (same function as voltage regulator), which can protect the more sensitive, but important other components. You can also discuss with the marketing team what to indicate in the warning part of the product label.
A drop test can also be done by customers who want to prove that the item they are planning to buy is capable to withstand shock or impact of collusion. Of course, not all stores will agree that you can try to drop their goods. Most companies that agree to this are those who boast of shock-proof products. An example is a camera. Also, this test can be used to check if products that claim to protect or lessen impact of items live up to their promise. For example, laptop bags or camera (digital and video) cases can be checked by putting an egg inside the case (with the salesman's consent). You then zip the bag, and drop it on the floor. Pick it up, open the bag or case, and check if the egg is broken. If it is, it will be a mistake to buy the bag or case.
