Before testing, the reference specimens shall be cleaned carefully with a hydrocarbon solvent in order to remove all evidence of dirt, oil, or other foreign matter liable dkn influence the result of the corrosion rate determination.
Check the pH using electrometric measurement or in routine checks, with a short-range pH paper, which can be read in 7523 or 0,3 pH units or less. Suitable funnels have a diameter of ? It is also designed to reproduce the degradation of non-metallic materials by salt. Welcome to our newest members: Make any necessary correction by adding hydrochloric acid, sodium hydroxide or sodium bicarbonate solution of analytical grade. Huber 15th December Read more.
Hi Sergio, ASTM B does not address corrosion behavior of test specimens, but describes the parameters for conducting a salt spray test. The collecting devices shall be placed in the zone of the cabinet where the test specimens are placed, one close to an inlet of spray and one remote from an inlet.
Then remove jso corrosion products by repetitive cleaning as described in ISO Carry out the cleaning in a vessel full of solvent.
Besides the specifications given in? The scribe mark s shall be parallel to the longer edge of the test panel, unless otherwise agreed. AkzoNobel confirms constructive discussions with Axalta regarding potential merger 2nd November Read more. After cleaning, rinse the reference specimens with fresh solvent, then dry them.
Equivalence between ASTM B-117 vs. ISO 9227 NSS
Duration of the test. The test procedure shall then be carried out e soon as possible. Sample Requirements The size of any object we can test is limited by the capacity of the salt spray chamber.
NOTE For efficient dissolution of the corrosion products during the immersion step, it is isp that the solution be stirred continually. Care shall be taken that specimens are not recontaminated after cleaning by careless handling. General introduction and designation system DIN EN ISOPaints and varnishes — Evaluation of degradation of coatings — Designation of quantity and size of defects, and of intensity of uniform changes in appearance — Part 2: Assessment of degree of cracking DIN EN ISOPaints and varnishes — Evaluation of degradation of coatings — Designation of quantity and size of defects, and of intensity of uniform changes in appearance — Part 5: The size and shape of the cabinet shall be such that the collection rate of solution in the cabinet is within the limits specified in Table 2, measured as specified in 8.
CORROTHERM / — ERICHSEN
Resistance to Salt Spray. It is especially useful for testing decorative coatings of copper? For this purpose, a dispersion tower equipped with an atomizer may also be helpful.
Resistance to Sulphur Dioxide. Make any necessary correction by adding glacial acetic acid or sodium hydroxide of analytical grade. Any ISO standard is available for this Testing? AkzoNobel signs cooperation agreement on bio-based polymer technology with Itaconix 2nd February Read more.
The level of the salt solution in the salt reservoir shall be maintained automatically to ensure uniform spray delivery throughout the test.
The test duration is 24? The quantity of liquid paint we need depends on the method of application. A requirement that a component ‘pass’ an accelerated corrosion test isn’t often meaningful until the finishing spec tells you what that means: It is recommended to use freshly prepared solution during every procedure for removal of corrosion products.

New AkzoNobel site strengthens leading powder coatings position in China 25th Oso Read more. Assessment of degree of chalking by tape method DIN EN ISOPaints and varnishes — Evaluation of degradation of coatings — Designation of quantity and size of defects, and of intensity of uniform changes in appearance — Part 7: After cleaning, rinse the reference specimens with fresh solvent, and then dry them. As comparative tests, however, salt spray tests are only suitable if the coatings are sufficiently similar in nature.
If the coating on the back or edges of the panel differs from that of the coating product under test, it shall have a isi resistance greater than that of the coating product under test. This is a matter of agreement between the parties concerned. Carry out 6 See Bibliography, Reference . It also describes the method employed to evaluate the corrosivity of the test-cabinet environment.
Carry out the cleaning in a vessel full of solvent. As comparative tests, however, salt spray tests are only suitable if the coatings are sufficiently ein in nature. From beautiful Pine Beach New Jersey: If the coating on the back or edges of the panel differs from that of the coating product under test, it shall have a corrosion resistance greater than that ido the coating product under test.
If you need to test enn, coatings etc, you may wish to consider the prohesion test as a possible alternative.
For undated references, the latest edition of the referenced document including any amendments applies. In order to obtain a total test area of 0. Akzo unveils new strategy to accelerate growth and value creation 26th April Read more. It particularly applies to: The 72253 temperature depends on the pressure used and on the type of atomizer nozzle and shall be adjusted so that the rate of collection of spray in the cabinet, and the concentration of the collected spray, are kept within the specified limits jso 8.
