These acidified test solutions generally have a pH of 3. This is compared to expectations, to determine whether the test is passed or failed. Such tests are commonly referred to as modified salt spray tests. The suffix to the main standard number indicates norma astm b117 year of publication.
Equivalence between ASTM B vs. ISO NSS
Test specimens are placed in an enclosed chamber and exposed to a continuous indirect spray of salt water solution also referred to as fog or mist which falls-out on to the specimens at a rate of 1.
ISO gives norma astm b117 guidelines for proper measurement of corrosion resistance norma astm b117 hot-dip galvanized specimens.
B is widely used as a rapid method for evaluating coating and materials performance under highly corrosive marine conditions. Variations to the salt spray test solutions depend upon the materials to be tested.
ASTM G85 is the most popular global test standard covering modified salt spray tests. In this context they norma astm b117 be considered to be equivalent and interchangeable terms. Usually, the materials to be tested are metallic although stone, ceramics, and polymers may also be tested and finished with a surface coating which is intended to provide norma astm b117 degree of corrosion protection to the underlying metal.
ASTM B is an excellent reference document for the norma astm b117 spray practitioner, with many helpful hints and tips contained in its useful appendixes. Test specimens are placed in an enclosed chamber, and exposed to 1 of 2 possible changing climate cycles. Norma astm b117 pH of the salt solution fall-out should be maintained at a neutral pH pH 6.

Salt spray test – Wikipedia
The appearance of corrosion products rust or other oxides is evaluated after a pre-determined period of time. Cyclic corrosion testing is better suited to this. Something totally different like zinc-alloy plating, organic coatings, etc. This test can be used to test the relative resistance to corrosion norma astm b117 coated and uncoated metallic norma astm b117, when exposed to a salt spray climate at an elevated temperature. But benchmarking performance is something altogether different.
The principle application of the salt spray test is therefore enabling quick comparisons to be made between actual and norma astm b117 corrosion resistance.
Most norma astm b117, the time taken for oxides to appear on the samples under test is compared to expectations, to determine whether the test is passed or failed. This public forum has 60, threads. A personal good afternoon to all, I am Jose of Curitiba, I am a painting inspector, I am a specialist in the area of Salt Spray, and have a problem and knowing of the competence of all readers in corrosion, perhaps they can help me. Electroplated zinc-nickel steel parts can last more than hours in NSS test without red rust or 48 hours in Norma astm b117 test without red rust Requirements are established in test duration hours and coatings shall comply with minimum testing periods.
Synthetic seawater solutions are also commonly specified by some companies and standards. The salt spray test is one of the most widespread and long established corrosion tests. Salt Spray Testing Discussion. This produces a corrosive environment of dense salt water fog also referred to as a mist or spray in the chamber, so that test samples exposed to this environment are subjected to severely corrosive conditions.
Dear Brian and Davey, thank you very much for your answers.

The test results norma astm b117 be examined visually to measure the integrity of the alloy and or its coating. Remember that accelerated testing is not a proper indication of real world performance.
Practitioners applying the ASTM B test standard are norma astm b117 for checking they are using the most appropriate version for their application.
Comparisons of pre- and post-testing photos norma astm b117 be taken and if needed a comparison of a corroded sample from the field may also be used. Test specimens are placed in an enclosed chamber and exposed to a continuous indirect spray of salt water solution, prepared in accordance with the requirements of the test standard and acidified to pH 3.
Most Salt Spray Chambers today norma astm b117 being used NOT to predict the corrosion resistance of a coating, but to maintain coating processes such as pre-treatment and painting, electroplating, galvanizing, and the like, on a comparative basis. Common materials that can be tested using the salt spray test are:. So if you want to know how to set up a salt spray cabinet or how to make the salt solution, then B is a reference.
We have three different testing chambers including a small medium and large chamber. This is considered an out norma astm b117 date browser. Test Conditions Test specimens are placed in an enclosed chamber and exposed to a continuous indirect spray of salt water solution also referred to as fog or mist which falls-out on to the specimens at a rate of 1.
From Wikipedia, the free encyclopedia. Salt spray testing is an accelerated corrosion test that produces a corrosive attack norma astm b117 coated samples in order to evaluate mostly comparatively the suitability of the coating for use as a protective finish.
Equivalence between ASTM B-117 vs. ISO 9227 NSS
Options include the following:. However, these testing norma astm b117 neither provide information of testing periods for the coatings to be evaluated, nor the appearance of corrosion products in form of salts.
Although the majority of salt spray tests are continuous, i. Options include the following: The b117 of salt fog testing is to collect b1177 resistance data from coated and non-coated alloys and also norma astm b117 wide variety of other materials including plastics 12, 3.
