In Method 2, continued exposure to the sodium chloride solution is used axtm monitor the extent of corrosion as a function of time. It is the responsibility of the user of this standard to b95 astm b safety and health practices and determine the applicability of regulatory limitations prior to use.
The specimens, placed in the specimen supports for testing, are shown in Figure 6. Method 2 of ASTM B is really only suitable for those materials that have an extended life prior to the appearance of corrosion products.
An example of the experimental set-up is shown in Figure 1. You may delete a document from your Alert Profile at any time. The corrosion life atsm Method 1 is the time of the last examination before the observation of a stain or rust. This standard is also available to be included in Standards Subscriptions.
