Tell The Manufacturer Your Test Specimen Type

It is important to inform the chamber manufacturer of the type of product being test in the chamber. However, if all the details are not given to the chamber manufacturer, the resulting selection may not be best for your application and could cause safety risks. 
The chamber manufacturer should understand your test objectives as well as you do. The more information he has regarding your product and your test requirements, the better equipped he will be in either selecting a standard product to meet your needs or proposing a custom chamber designed to meet the special requirements of your product testing. 
For example, hydraulic valves under pressure are being test at various temperatures. Hydraulic lines enter and exit the chamber through an access port. Rarely, if ever, a fluid leak occurs in the 
chamber. This does not concern the operator since the warmest temperature achieved in the chamber is well below the auto-ignition point of the fluid. However, if a leak occurs the chamber will be at risk for an explosion. This is due to the fact that the standard nichrome wire heater used in most chambers can exceed 1000˚F surface temperature. 
For this type of application temperature limited sheath heaters must be used at a minimum. Depending on the application, a classified explosion proof chamber may be required. There are many scenarios which could be used for examples, but the bottom line is to make sure you have given your chamber manufacturer all the details of your tests.
