ASSE 6010 candidates need 4 years of documented plumbing or mechanical installation experience and a minimum 32-hour course taught by an ASSE 6050 instructor. NITC's written exam has 100 closed-book questions, a 2-hour limit, and a 77% passing score. The practical is a braze test of 1-1/2 in. Type L couplings. The credential lasts 3 years, and the employer must document brazing continuity every 6 months. Product installation knowledge is 45% of the written exam.

Frequently Asked Questions
What does an ASSE 6010 Medical Gas Systems Installer do?
An ASSE 6010 installer installs medical gas and vacuum piping and components in health care facilities under NFPA 99, including brazing. NFPA 99 requires everyone who installs this piping, including every brazer, to be certified to ASSE 6010. A certified installer may not use the certification to oversee noncertified workers.
What are the prerequisites for the ASSE 6010 exam?
Candidates need at least four years of documented practical experience installing plumbing or mechanical systems. They must also complete a minimum 32-hour training course taught by an instructor certified to ASSE 6050. Some states add requirements; Minnesota, for example, also requires a plumbing license.
How many questions are on the ASSE 6010 exam, and what is the passing score?
NITC's written exam is closed book, with 100 multiple-choice questions and 2 hours allowed. Candidates need 77 correct answers (77%). They must also pass a practical brazing exam. Other certifiers set their own formats and cut scores, so check your certifier's candidate bulletin.
What is the ASSE 6010 practical brazing exam?
At NITC, candidates braze the BTS15 test package: 1-1/2 in. Type L copper tube with standard stop couplings. It includes two joints on a horizontal coupling and two up-flow joints on a vertical coupling. AWS Certified Welding Inspectors examine the coupons to ASME Section IX. BTS15 qualifies nominal Type L and K tube from 5/8 in. through 2 in.
How much does ASSE 6010 certification cost?
NITC's March 2026 price list shows $130 for a proctored written exam without the braze, $150 with the braze in the same session, and $75 for a separate BTS15 braze test. Testing at a Prometric center adds a $60 processing fee for a 2-hour exam. Training course tuition is set by each ASSE-approved school.
How long is ASSE 6010 certification valid, and how is it renewed?
NITC certifications are valid for three years. The employer must document brazing continuity every six months, and a lapsed braze is requalified with one vertical up-flow joint. Recertification requires a 4-hour NFPA 99 update course from an ASSE 6050 instructor and a 40-question open-book exam passed at 80%.
Why is a nitrogen purge required during medical gas brazing?
NFPA 99 requires joints to be purged continuously with oil-free, dry nitrogen NF so copper oxide cannot form inside the pipe. Purge flow is controlled with a regulator and a flowmeter, never a regulator alone. An oxygen analyzer must read below 1% before brazing starts, and the purge continues until the joint is cool to the touch.
