Corrosion and rusting are culprits that can cause buildings and bridges to collapse, auto parts to get jammed and bathrooms can get flooded. Thus, it is important that metal components, automobile parts, pipes, fittings & coated panels should be tested for corrosion resistance.
This can be easily done using a comprehensive and reliable piece of equipment called Salt Spray Chamber.
Salt Spray Chamber
It is a highly effective and efficient equipment used to evaluate the resistance to corrosion of coatings, paints and small metal objects, including mechanical parts. During the salt spray test, the sample is exposed to a very intensive salt based atmosphere for a specified period of time. The conditions inside the salt spray test chamber simulate the environmental conditions responsible for weathering and rusting, thus, they considerably accelerating the corrosion process.
As per industry standards, a product should be tested under accelerated conditions for 240 to 1000 hours, for the purpose of corrosion testing. However, the time period can be customized according to specific requirements.
Best Salt Spray Test Chamber in India
Presto Testing Instruments manufactures and provides the best Slat Spray Chambers in India. The Chamber utilizes refined salt for salt spray testing. The quality of salt used complies with a purity standard and meets the latest requirements.
Presto Salt Spray Chamber adheres to ASTM B117 and JIS Z 2371 standards. The chamber is duly fitted with a sophisticated atomizer, which ensures an even distribution of salt spray. A timer is fitted to ensure precise sample collection rates throughout the test cycle.
Benefits of Using Presto Salt Spray Chamber:
üBy conducting Salt Spray Testing using a Salt Spray Tester manufacturers can ensure that their products can withstand corrosion and are resistant to rusting.
üNowadays, different kinds of protective coatings and weather resistant products are applied to surfaces, to increase the life of products. Conducting Salt Spray Tests enables product developers and manufacturers to determine the most effective solution for making rust proof coatings.
üTo assess the exposure of road salt to automotive parts, especially around the under body section of a vehicle, salt spray testing is very beneficial.
üUsed to estimate the service life of the component/product, performing the salt spray test can ensure that the product has a good life span and id durable.
üIt can also be used for predicting the suitability of a protective coating. This can be performed in relation to providing effective corrosion resistance.
üTechnicians also use salt spray chambers for research and assessment of edge protection, blistering and creep defects.
üSometimes corrosion occurs underneath the coating and leads to the formation of a membrane, exposing the untreated surface to air and moisture. This leads to ‘blistering’, which usually starts to become evident in the center of the metal test panels. Salt Spray Testing can be used to determine blistering.
Samples/Products for Presto Salt Spray Chamber
The Salt Spray Chamber can be used to perform corrosion testing on a wide variety of samples, such as:
ücoated & uncoated panels
üscrews, nuts & bolts
üsprings and bearings.
Industries where Presto Salt Spray Chamber is used:
Salt Spray Chambers are widely used in various industries such as:
Air craft and aviation
OEM Manufacturers & suppliers
This is a simple test which can be easily used for the evaluation of corrosion resistance of parts or finished surfaces.
It is, therefore, mandatory that all components are thoroughly tested and documented for their resistance to corrosion.
Procedure for Corrosion Testing Using Salt Spray Test Chamber:
Salt spray test results are a reliable source for assessment and evaluation of the impact of moisture and weathering, in terms of rusting of a product. The Salt Spray Chamber is designed to create the precise environmental test conditions demanded by the industry, today.
The chamber can accommodate a number of small metal panels or objects. Thus multiple products can be tested at the same time and can be compared scientifically in the same controlled test environment.
During the test cycle the corrosion levels are monitored, at specified time intervals. This is done by opening the cabinet and taking photographic evidence of any surface oxidization. The metal plate surface is examined for evidence of corrosion or rusting throughout the test cycle.
