Environmental Test Chambers & Environmental Test Chamber Manufacturers

Environmental test chambers reproduce environmental conditions within a contained space for the purposes of evaluating the long-term effects of specific changes upon objects such as industrial products and materials, electronic products and other components. These conditions simulate those which a product will typically encounter in the span of its useful life. Test results can show the process of product decay and degradation and help predict the potential lifespan of a product or material.

Environmental chambers evaluate product quality and reliability, and identify manufacturing flaws and weaknesses in those products before they are released to the general market. Common tests undertaken in environmental test chambers are extremes of temperature and sudden variations of temperature in temperature chambers and cryogenic chambers, the effects of humidity and moisture in humidity test chambers, and salt spray test chambers which record the degrading effects of salt water on objects for manufacturer analysis. Other types of chambers include: AGREE chambers, altitude chambers, thermal shock chambers and vacuum test chambers. Causal environmental conditions such as airborne and structural vibrations, shock, dust and sand, electromagnetic and UV radiation are further tests carried out in test chambers to evaluate a product’s reaction to the elements. As the nature of the tests which environmental chambers perform is widely varied, the common sizes of the chambers are also as broad. Test chambers can range from simple, smaller benchtop test chambers which can be used to test a small component, to a variety of sizes of altitude chambers, to the larger, more complex walk-in test chambers, and even drive-in chambers for vehicles and aircraft.

The validity of environmental test results is important as it is these results that future product modifications and improvements are based upon. Therefore, design and construction of the environmental test chamber has to be carefully considered. As it is a process test, chambers typically have a means of viewing and monitoring the testing procedure either through a viewing hole, or through a video feed. In some cases, an environmental test chamber will have a reach-in capability in order for the testing engineer to handle the product or material being tested. The method of process control is another consideration to be undertaken as control panels can be either analog or digital, fed by a computer or the web etc. The consistency with which an environmental test is performed is crucial to the reliability of the results, therefore it is wise to refrain from including unnecessary man-made interference with the process to keep it as uniform as possible. Each element of the test and testing conditions has to be taken into consideration – such as already existing environment and climate, the potential addition of interior chamber lighting and thus extra heat, and the variations that already exist between products and materials. Strict control during the process will yield the most accurate and useful results from the tests.

Test chambers are designed with the capacity to replicate not only normal, but also extreme environmental conditions. Temperature chambers can typically reach temperatures above 350 degrees Fahrenheit, and cryogenic chambers produce temperatures on the other end of the scale achieving lows of -300 degrees Fahrenheit, or even lower with the help of liquid nitrogen. In addition to temperature variations which can be further tested by thermal shock chambers, humidity and air moisture content can be replicated with humidity ranging from 10-100% in most humidity chambers. These are basic tests which are commonly carried out on most products. Altitude chambers simulate extremely high altitudes to test the effects of pressure and air change, and routinely 100K ft. to 200K ft. are achieved in vacuum environmental chambers. Means must be implemented to record the data of the product response to these tests for analysis, verification and future development and adjustment planning. Therefore, there is a two areas of focus within a testing chamber – that of producing the controlled conditions for the testing of the object or product, and the accurate recording of the results of that testing.

Industries which use environmental testing include: automotive, engineering, construction, medical, pharmaceutical, food processing, packaging and consumer. Everyday products such as car parts, cigarettes, make-up, medicines and kitchen appliances undergo testing by manufacturers to ensure their durability and effectiveness in certain environmental conditions. An important reason for the process of environmental testing is that it finds flaws and weaknesses in product design and lifespan before it reaches the public market. These findings allow for production adjustments and result in a better quality product arriving on the market. Once a product is tested and approved in extreme circumstances, there will be lower warranty claim expenses from replacement and repair, and this saves manufacturer expenditure. Without testing products in a variety of environmental conditions, it is a high risk for a manufacturer to sell the products under warranty. Customers are increasingly demanding longer warranties on products and goods, and it is imperative that a manufacturer has tested the product that he or she is guaranteeing to avoid high reimbursement costs. Testing can take many hours and can be a costly procedure depending on the size and process undertaken, and yet it is a wise manufacturing choice to undergo environmental testing, especially in terms of long-term expenditure and future benefit.
