  • Optional Requirements for Interim Credentials for Pipefitter/Steamfitter
    To ensure that all United Association (UA) apprentices and journeyworkers receive the appropriate skills and knowledge from any of the 330 UA authorized training centers (covering 284 registered apprenticeship programs and over 40,000 registered apprentices), the International Pipe Trades Joint Committee Training (IPTJTC) has committed tremendous resources to the development of curriculum, standards and certifications (including 3rd party groups1). The IPTJTC works in partnership with government, education, and industry groups (private and non­profit) in the development and validation of this material to assist in preparing these individuals for a successful career in the piping industry. Optional Requirements for Interim Credentials for Pipefitter/Steamfitter Level 1 1,700 – 2000 Hours OJL and 1st Year RI Completion of Brazing Certification UA‐51 – The completed braze test assembly shall be visually examined for cleanliness and the presence of brazing filler metal all around the joint at the interface between the socket and the pipe. Outside surfaces shall be free of excessive braze metal and oxidation. Sectioning tests shall be in accordance with ASME Code Section IX. OSHA 10/30‐Hour Course – Smart Mark is an OSHA approved safety and health training program. It is a standardized and intensive program that was developed in 1998 by the Construction Industry Partnership (CIP) that prepares construction industry workers to identify hazards and prevent on‐the‐job accidents. Soldering Certification – The Copper Development Association Inc. (CDA) regularly receives inquiries regarding the methods and procedures required to qualify installers for the installation of soldered‐joint copper piping systems. Currently, there are no known qualifications requirements developed and certified by any consensus code‐writing body.
