Significance and Use
This test method provides a measurement of methanol content of formaldehyde solutions. The results of these measurements can be used for specification acceptance.
This test method is applicable to 37 % formaldehyde solutions containing 0 to 2 %, 6 to 8 %, or 12 to 15 % methanol.
1.1 This test method provides for the calculation of the methanol content of commercially available 37 % formaldehyde solutions and is based on the relationship of specific gravity to formaldehyde and methanol content. Separate equations are given for three ranges of methanol: 0 to 2 %, 6 to 8 %, and 12 to 15 %.
1.2 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.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 For hazard information and guidance, see the supplier's Material Safety Data Sheet.
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. Specific hazard statements are given in Section 4.
