Brazing Processes

NITC has been the leader in the qualifying of medical gas installers for brazing since the early 1990’s. From the start NITC had a single practical test for brazing which became the industry standard for the qualification of ASSE 6010 Installers. As the requirements for Brazing of Medical Gas and Vacuum System piping have evolved over the years, NITC has found it necessary to implement some important changes that (1) reflect the most up-to-date industry practices and (2) ensure compliance with the changes to the codes and standards. NITC has recently qualified additional Practical Braze Tests to cover the full range of copper tube sizes used for the installation of Medical Gas Systems as required by the latest editions of the NFPA 99 Healthcare Facilities Code and ASME Section IX Boiler and Pressure Vessel Code. The additional NITC Medical Gas Braze Tests  listed within the table below may be used for the Performance Qualification Testing of Medical Gas Brazers.

Brazer Performance Qualification Tests
NITC Brazer Test Number Qualification Range Type L Qualification Range Type K
BTS34 ¼” – 1” ¼” – 1”
BTS15 * 5/8” – 2” 5/8” – 2”
BTS2 1” – 3” 1” – 3”
BTS4 2” – 5” 2” – 5”
BTS6 2 ½” – 6” 2 ½” – 6”
BTS8 2 ½” – 8” 2 ½” – 8”
Large Diameter Tube – Modified Cup Depths
BTS4SEXT 2” – 6” 2” – 6”
BTS6SEXT 2 ½” – 8” 2 ½” – 6”

* Required for ASSE 6010 Medical Gas Installer/Brazer and any additional Medical Gas Braze

NOTE: All “Qualification Range Pipe Diameters” are expressed in Nominal/Standard Size Inches for Medical Gas Type “L and K” Tubing. (CDA Publication A4015-14/16: Copper Tube Handbook, Table 14.2f) Example: 5/8” Type “L and K” tubing have an outside diameter (O.D.) of ¾” [0.750”]

To qualify for the ASSE 6010 Medical Gas Certification, the candidate must achieve a passing score on the NITC 6010 Medical Gas Installer written exam and successfully pass the practical brazing component; following the instructions within the NITC BTS15 Braze Test Specification. Additional NITC Braze Tests may be qualified during the same braze session, however, the ASSE 6010 Medical Gas Installer/Brazer Certification may not be awarded until the written and BTS15 practical exams have been successfully accomplished. NITC Braze Tests Documentation  should be downloaded for each braze session. Follow the information contained within the Braze Test Specification and the NITC’s Step by Step Instructions for the Medical Gas Braze.  Complete the required Brazer Qualification Record (BQR) for each braze. Ship completed BQR and coupon to NITC Southern Regional Office, 2540 Severn Ave., Suite 200, Metairie, LA 70002, Attention: Janel Mezzic, Phone: 888-234-6834 Continuity of initial and additional braze qualifications are maintained by Continuity Form for Brazer. Braze qualifications remain in effect indefinitely; however, a lapse in continuity will require re-qualification of each previously held credential.
