Results Produced Length change of mortar bars immersed in sulfate solution. Further discussion of these and other technical issues is given in the Appendix. When tests are made that are expected to produce results that are close to an acceptance- rejection value, it is recommended that reagent grade chemi- cals be used.

Last previous edition approved in as C — The length change of v1012 bars immersed in sulfate solution is the indicator.

Determine the pH of the solution before use; reject the solution if the pH range is outside 6. Significance and Use 3.

Other sulfate concentrations or other sulfates such as MgSO4 may be used to simulate the environmental exposure of interest. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Combining values from the two systems may result in non-conformance with the standard. It is the responsibility of the user of this standard to establish appro- priate safety and health practices and determine the applica- bility of regulatory limitations prior to use.

Any anhydrous or hydrated sodium sulfate may be used if the water content of the salt is checked by loss on ignition and proper corrections made to account for the specified sulfate concen- tration. Can extend time of testing for additional charge.
