    Significance and Use

    3.1 Soda ash is used in a number of manufacturing processes. The procedures listed in 1.2 are suitable for specification acceptance and manufacturing control of commercial soda ash.

    1. Scope

    1.1 These test methods cover the analyses usually required on commercial soda ash (sodium carbonate).

    1.2 The analytical procedures appear in the following sections:




    Total Alkalinity, Titrimetric

    8 – 15

    Sodium Bicarbonate, Titrimetric

    17 – 24

    Loss on Heating, Gravimetric

    26 – 32

    Moisture, Calculation

    34 – 38

    Sodium Chloride, Titrimetric

    40 – 46

    Sodium Sulfate, Gravimetric

    48 – 54

    Iron, Photometric

    56 – 64

    Sieve Analysis

    66 – 72

    1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

    1.4 In determining the conformance of the test results using this method to applicable specifications, results shall be rounded off in accordance with the rounding-off method of Practice E29.

    1.5 Review the current Safety Data Sheets (SDS) for detailed information concerning toxicity, first aid procedures, handling and safety precautions.

    1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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. Specific hazards statements are given in Section 6.

    1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
