 [0.001 % to 0.005 %] 10 - 20 Lead by the Dithizone Spectrophotometric Test Method
 [0.001 % to 0.05 %] 21 - 31 Chromium by the Sodium Peroxide Fusion-Titrimetric Test Method
 [50.0 % to 99.5 %] 32 - 38 1.3 Units-The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 6 and in special "Warning" paragraphs throughout these test methods. 1.5 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.
