Historical Standard: Standard Test Method for Determination of Ethoxyl or Hydroxyethoxyl Substitution in Cellulose Ether Products by Gas Chromatography<\/h4>\n
\n

ASTM D4794<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This test method is applicable to the determination of ethoxyl or hydroxyethoxyl substitution in cellulose ether products by a Zeisel gas chromatographic technique.<\/p>\n

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.<\/p>\n

1.3 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 5 and Note 3.<\/span><\/span><\/p>\n
