ASTM D2363-79(2006)

Standard Test Methods for Hydroxypropyl Methylcellulose

ABSTRACT
These test methods cover the testing of hydroxypropyl methylcellulose. The test methods are as follows: moisture; ash; chlorides; alkalinity; iron; heavy metals; methoxyl content; hydroxyproproxyl content; viscosity; pH; solids; and density.
SCOPE
1.1 These test methods cover the testing of hydroxypropyl methylcellulose.
1.2 The test procedures appear in the following order: SectionsMoisture4 to 6Ash (as Sulfate)7 to 10Chlorides (as NaCl)11 to 14Alkalinity (as Na2CO 3)15 to 18Iron19 to 24Heavy Metals25 to 29Methoxyl Content30 to 35Hydroxypropoxyl Content36 to 41Viscosity42 to 46pH Solids48 to 51Density52 to 56
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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 a specific hazard statement, see 33.5.1.
