CSA Standard B620 specifies
requirements for highway,
portable, fiber reinforced plastic
and pressure/vacuum liquid
waste highway tanks for the
transportation of dangerous
goods. Industries from across
Canada were consulted and
formed a committee to evolve
this standard to what it is today.
Previous editions were published in 1987, 1998, 2003 and
the newest in 2009.
The standard is used mostly for
tanks/vessels that travel on
roadways but may include
those used on rail and marine. It
considers the design, construction, certification, assembly,
modification, repair, testing,
inspection and periodic retesting, identification and maintenance of these tanks. The Transportation of Dangerous Goods
(TDG) Acts and Regulations
apply the Standard B620 as well
as what is contained in their
acts and regulations. Did you
know that?
Any facility that is performing
inspections, manufacturing of,
modification, assembly, repair
or testing must register and
maintain a quality control
manual with Transport Canada.
This manual describes the
activities of the facility, what
they can do, not what they can’t
do. Our manual is very strong
in the areas of training and
safety of all personal and equipment they are working on. All
testing procedures are
contained in this manual and
followed accordingly.
What criteria is required for
each level of inspection and
how often are they required?
Periodic testing and inspection
are contained on tables 1 and 2.
Did you know that a hydrostatic or pneumatic test and
inspection is required if...
... the tank shows signs of dents
abrasions corroded or signs on
leakage?
...the tank was involved in an
accident that may have compromised the tank
...the tank hasn’t been used for
one year or more to transport
dangerous goods
...the tank has been modified
How do you compare
inspections done from one
facility to the next?
We offer inspection services
wherein we follow strict
policies and procedures for our
safety and our customers peace
of mind. Check out our
inspection services listed

level gauges operating
properly
the specification plate and
other markings are legible
and all proper information is
stamped
all attachments and major
appurtenances are not
damaged or badly corroded
hoses for abrasion
self-closing relief valve for
corrosion or damage
full opening of rear head for
cuts, cracks or splits
(if the damage is more
than .5” in depth, it must be

shutdown system
Note:
If tank is corroded, a Thickness
Test will be performed.

defects, wear abrasions or

Tanker Unit
sub-frame is unbolted from
frame cleaned if necessary;
same inspection as above is
performed; sub-frame replaced, nuts and bolts tightened to specification
Leakage Test
includes, but not limited to:
all product piping and
valves shall be in place and
operative
all relief valves set to below
test pressure removed and
opening capped or plugged
Hydrostatic test on any
tanks over MAWP of 5psi
Pneumatic test with the use
of soapy water on any tanks
MAWP of 5psi and below
80% of MAWP is held for
minimum of 5min
bench testing of relief valve
An External (Visual) Inspection is also done at this
interval.
Thickness Test
includes, but not limited to:
Test of thickness of tank
shell and head around openings and piping that show
signs of high stress or abrasion
Pressure Test (Hydrostatic)
relief valves are removed
and plugged or blocked. At
this interval, the relief valve
is sent out to a certified
valve company for inspection, cleaning, repair and
certification as required by
Standard B620. This information is kept on file linked
to the tank which is being
tested.
Pressure Test (Pneumatic)
applied to tanks with MAWP of
5psi or less
the procedure is similar to
the Hydrostatic Test but
compressed air is used.
Also non-destructive examination (NDE) that is required or if
there is any fault or defect that
is questionable, a second party
that is registered to do the required level of inspection will
be called in.
As required by the Standard
B620, a written report for each
inspection or test is dated and
signed by the tank inspector
and is provided to customer. A
copy is always kept on file as
required by Transport Canada
for auditing or reference purposes.
the tank is completely filled
with water and pressured to
the manufacturer’s test pressure and/or referencing a
chart contained in the Standard B620. This pressure is
held for 10min minimum.
The tank and all outlets are
checked for leaks during this
time.

Lined and unlined tanks in corrosive service must have an annual internal inspection. The lined tanks
must also have the lining checked at the same time interval. Unlined tankers in corrosive service must
have an annual internal inspection and a thickness test done every 2 years.

All tanks with an upper coupler must have the tank checked for corrosion under the upper coupler every
5 years.
