Testing and Balancing is an ever-growing field within
the sheet metal industry. The Testing, Adjusting and
Balancing (TAB) technicians' job is to test existing air
and hydronic systems to ensure that they are operating
as they were designed. After the technician tests the
system it is then his job to adjust, or balance, the
system to ensure that the proper amount of air or water
is being delivered to the proper space.
TABB recognizes that an ITI Certified TAB Technician is a competent,
reliable, and qualified professional who is able to
perform, without on-the-job supervision, testing,
adjusting and balancing of air and hydronic building
environmental systems to produce the design objectives.
To become an International Training Institute (ITI)
Testing, Adjusting and Balancing (TAB) Certified Technician,
an applicant must show sufficient experience, pass the
air and hydronic written tests, and successfully
complete comprehensive air and hydronic performance
tests. The tests are designed to be mastered by
technicians who are fully qualified and experienced.
The written tests are offered in a traditional
classroom setting or online. Applicants are allowed 2
1/2 hours to complete each test. Upon passing the
written exams, the applicant is eligible to take the
performance tests at one of ITI's certified labs. Each
test takes one-full day in length. After passing the
performance tests, the applicant is granted ITI TAB
Certification status.
