More C Chloride content, along with other factors, can be indicators for the possibility of corrosion of embedded metallic materials. This test method is used to determine the water-soluble chloride content in cementitious mixtures, either in new construction or existing structures. For example, water-soluble chloride content could increase due to additional chloride ingress.
Alternatively, water-soluble chloride content could decrease due to chloride-binding or leaching. Take caution when comparing results from this test method with those from other test methods. Blast-furnace slag aggregates and cements contain sulfide sulfur in concentrations that are capable of such interference and produce erroneously high test results.
Treatment with hydrogen peroxide, as discussed in Test Methods C, is used to eliminate such interference. Such chloride will be detected by use of this test method.
Scope 1. These notes and footnotes shall not be considered as requirements of this standard. Within the text, the inch-pound units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Mikataxe Other light sources include mercury, cadmium, helium, and hydrogen where lters are used with the refractometer to eliminate unwanted emission lines. Benefit from extensive experience in petroleum testing technology. The temperature control unit external or internal shall have the following control specication: A wide range of sample filling units and measuring modules can be added at a later date, making the Modulyser Unlimited class fit for future requirements. No other units of measurement are included in this standard. Report the calculated value and the test temperature, for example: Warning—Volatile hydrocarbon samples are ammable.
