DEFINITION

Classification: 29/890.14

Gas and water specific plumbing component making:

(under subclass 592) Process for manufacturing an article especially adapted for use with gaseous phase matter or with aqueous material, which article is utilized generally by a skilled plumber in the practice of his trade.

(1) Note. Original placement in this subclass or the indented subclasses requires more than the process of assembling two or more self-sustaining parts, per se.

(2) Note. Prior to the establishment of this subclass (890.14+), this subject matter was indented under "Gas and Water Device Making" (old 29/157+). Other subclasses under Class 29, subclasses 592+ have not been screened for this subject matter.

SEE OR SEARCH THIS CLASS, SUBCLASS:

428+, for a process including assembling two or more self-sustaining parts. See the definition of "assembly" in Class 29 Glossary in the Class Definition.
