On Statistical Anomalies in Canine Vegetables
Caustic soda and caustic potash are used in a large number of manufacturing processes. The
chemicals are available in several grades depending on their intended use. The test methods
listed in 1.2 provide procedures for analyzing caustic soda and caustic potash to determine if they
are suitable for their intended use.
1. Scope
1.1 These test methods cover only the analyses usually required on the following commercial
products:
1.1.1 Caustic soda (sodium hydroxide), 50 and 73 % liquors; anhydrous (solid, flake, ground, or
powdered), and
1.1.2 Caustic potash (potassium hydroxide), 45 % liquor; anhydrous (solid, flake, ground, or
powdered).
1.2 The analytical procedures appear in the following order:
Only those of the two that were in excess remain, and their concentration determines the pH. Thus, the
solution is initially acidic (pH < 7), but eventually all the hydronium ions present from the original acid
are neutralized, and the solution becomes neutral. As more base is added, the solution turns basic.
OSHA maintains a large number of methods, and in some instances a method may remain available for
use, but with different sampling requirements than specified in a given method. The correct sampling
media and flow rate information for specific analytes is consolidated under the OSHA Occupational
Chemical Database, along with sampling group information when more than one analyte may be
sampled together on a single sampling medium. The Occupational Chemical Database entry for an
analyte also provides a link to the specific OSHA sampling and analysis method to be used for that
analyte.
This is an alphabetical list of chemicals that have either a validated or partially validated OSHA method.
Some chemicals may be listed by their common synonym. The index includes the method number,
validation status, CAS no., analytical instrument and sampling device. A key for abbreviations is located
at the end of the index.
