Many customers request the salt spray cabinet should meet the ASTM B117 testing standard, ASTM B117 salt spray corrosion tests and standards, ASTM B117 salt spray, ISO salt spray test, ISO , ASTM G85 salt spray test standard. Yes, They are the populare testing standard and used for salt spray cabinet testing period. This article mainly introduces the salt spray test chamber of ASTM B117. Welcome to take the initiative to send emails to our technical engineers to discuss the test methods and procedures of ASTM B117 standard.

The salt spray test is a standardized and widely used corrosion test method that is used to check the corrosion resistance of materials and surface coatings . The test is designed to produce a corrosive attack to coated samples, in order to evaluate the suitability of the coating for use as a protective finish. Most commonly, the materials that are tested are metallic and finished with a surface coating, but stone, ceramics, and polymers may also be tested.
According to ASTM International, ASTM B117, in and of itself, isnt a check specification. Rather, it outlines the quality observe for in operation salt spray (fog) equipment. B117 may be a document establishing the parameters and needs for in operation salt spray test chamber. ASTM B117 doesnt specify something regarding the kind of check specimen, dimensions, form or exposure periods to be used for a selected product, nor will it have any needs or steering for the interpretation of the results.

Most usually, the time taken for oxides to seem on the samples underneath check is compared to expectations, to work out whether or not the check is passed or unsuccessful.
Failure to satisfy this demand implies instability within the activity of the pre-treatment, or the paint quality, that should be self-addressed right away, so the forthcoming batches area unit of the specified quality. The longer the accelerated corrosion check, the longer the method remains out of management, and bigger is that the loss within the type of non-conforming batches.
Most salt spray chambers these days area unit getting used to not predict the corrosion resistance of a coating, however to take care of coating processes corresponding to pre-treatment and painting, electroplating, galvanic, and also the like, on a comparative basis. For example, pre-treated + painted parts should pass ninety six hours neutral salt spray, to be accepted for production.

There are many different named for salt spray cabinet, Such as salt fog chamber, cyclic corrosion chamber, salt spray test machine, corrosion testing machine, salt mist chamber, corrosion testing equipment. Salt spray testing labs has many corrosion testing methods. Such as salt corrosion spray test, humidity salt test, astm corrosion testing, cyclic corrosion test, acetic acid salt spray test.
According to astm salt spray test, salt fog testing astm b117, salt spray nozzle for salt spray cabinet need one additional stock for future accelerated corrosion test. Many salt spray test chamber manufacturers not much attention on this requirement, They always focus on salt spray chamber cost and selling price.
For this reason the salt spray cabinet is most frequently deployed in a very quality audit role, where, maybe, it are often accustomed check the effectiveness of a production method, corresponding to the surface coating of a aluminiferous half. Salt spray chamber for sale, salt fog chamber for sale are the traditional ways for marketing purpose. The distributors always try to get a salt spray chamber cheap price.
The distributors more attention on the salt spray cabinet price, corrosion test chamber price. As a salt testing equipment manufacturer, We insist that salt spray cabinet price should comply with the salt spray testing standard, like the salt mist corrosion test, salt test procedure for painting, If you only attention on the cyclic corrosion test chamber price, I am sure you will not buy a good quality salt spray corrosion test cabinet. We all know that a good quality equipment needs to be supported by a reasonable price. This is an eternal truth!
Corrosion Test Chamber or salt spray Test chamber in Chennai is one of the most accurate instruments for measuring the corrosion resistance of coating. Hence Salt spray chamber plays a very important role to test the specimen and analyse the quality of material being used by us for manufacturing. While In industries the material is exposed to various types of climatic conditions and chemical fumes which develop corrosion of components and parts.
While the tested product has been specifically designed to access the rust proof ability of components to withstand corrosion due to atmospheric condition. Hence It Provides complete flexibility in simulation of a real life weathering conditions. Therefore salt spray tester is designed as per standards which includes following standards
1.?Temperature Controller :- To Control temperature of Humidity / Chamber for heating of fogged water. with Auto Cut system to maintain temperature with in specified range 32 to 37 degree Celsius.
2. Hour Meter :- To observe / inspect condition of test samples periodically and recording long with time At least 3 digits in Hour and 2 digits in minutes
3. AIR SUPPLY :- The air supply must be free from Oil, Dust, , the air supply / pressure must be maintain in such a way. so that salt fog occurs, Pressure must be 1 Kg +/- 0.2 Kg
4. ATOMIZATION AND QUANTITY OF FOG :- The fog shall be such that for each 80 cm2 (4 Inch Funnel ) of horizontal collecting area. there will be collected from 1.0 to 2.0 mL of solution per hour based on an average run of at least 16 h
