    Significance and Use

    4.1 This test method provides a measurement of purity (assay) of aldehydes and ketones. The results of these measurements can be used for specification acceptance.

    4.2 The precision of this test method is applicable only to material having a purity of 98 to 100 %.

    1. Scope

    1.1 This test method covers the determination of the purity of certain commercially available aldehydes and ketones.

    1.2 In addition to all aldehydes and ketones, all compounds such as vinyl alkyl ethers, acetals, and ketals, that hydrolyze under the conditions of the reaction to form free carbonyl groups, react with the reagent and consequently interfere. Water, alcohols, saturated esters, and hydrocarbons do not react with the reagent, but large amounts of inert organic solvents are undesirable because of the effect on the indicator.

    1.3 For purposes of determining conformance of an observed or a calculated value using this test method to relevant specifications, test result(s) shall be rounded off “to the nearest unit” in the last right-hand digit used in expressing the specification limit, in accordance with the rounding-off method of Practice E29.

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

    1.5 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. For specific hazard statements, see Section 7.

    1.6 For hazard information and guidance, see the supplier's Material Safety Data Sheet.
