ASTM E1146-16

Standard Specification for Muriatic Acid (Technical Grade Hydrochloric Acid)

ABSTRACT
This specification covers muriatic acid, also known as technical grade hydrochloric acid. This specification includes requirements for muriatic acid available commercially in 20° Baumé and 22° Baumé concentration grades. Muriatic acid shall conform to the following chemical and physical requirements: total acidity of hydrochloric acid; iron content; and Baume gravity. To determine the requirements, a test shall be performed in accordance to the test method.
SCOPE
1.1 This specification covers muriatic acid, also known as technical grade hydrochloric acid.  
1.2 This specification includes requirements for muriatic acid available commercially in 20° Baumé and 22° Baumé concentration grades.  
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.  
1.4 Review the current Safety Data Sheets (SDS) for detailed information concerning toxicity, first aid procedures, handling and safety precautions.  
1.5 The following safety hazards caveat pertains only to the test methods portion, Section 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
