or user has complied with the record-keeping requirements hereafter
prescribed, shall be inspected at least once every two years inter-
nally and externally while not under pressure by the chief inspector
or by one of the deputy inspectors or special inspectors provided for
herein as to its construction, installation, condition and operation.
If at any time a hydrostatic test shall be deemed necessary to deter-
mine the safety of a boiler, the same shall be made, at the direction
of the inspector, by the owner or user thereof. Not more than twenty-
six months shall elapse between internal inspections, and external
inspections while under pressure shall also be made at no greater
intervals.

The owner or user of such boiler shall keep available for examina-
tion by the chief inspector or by any of the deputy inspectors or
special inspectors accurate records showing (i) the date and actual
time such boiler is out of service and the reason or reasons therefor,
and (ii) such chemical and physical analyses of samples of the boiler
water taken at regular intervals of not more than forty-eight hours
of operation as will adequately show the condition of such water
and any elements or characteristics thereof which are capable of
producing corrosion or other deterioration of the boiler or its parts.

[b] (c) If a boiler shall upon inspection be found to be suitable,
and to conform to the rules and regulations of the Board of Boiler
Rules, the owner or user thereof, shall pay to the chief inspector
and to be collected by him the sum of two dollars ($2.00) if such
boiler is required to be inspected annually and five dollars ($5.00)
if such boiler is required to be inspected once every two years, and
the chief inspector shall issue to such owner or user an inspection
certificate specifying the maximum pressure which the boiler may
be allowed to carry. Such inspection certificate shall be valid for
not more than fourteen months from its date in the case of boilers
required to be inspected as provided in subsection (a) of this Sec-
tion, and not more than twenty-six months in the case of boilers
required to be inspected as provided in subsection (b) of this Sec-
tion and [it] such certificate shall be posted under glass in the
room containing such boiler or in the case of a portable boiler, in
a metal case to be kept in the tool box accompanying the boiler. No
inspection certificate issued for a boiler inspected by a special in-
spector shall be valid after the boiler for which it was issued shall
cease to be insured by a duly authorized insurance company. The
chief inspector or any deputy inspector may at any time suspend
an inspection certificate when, in his; opinion, the boiler for which it
was issued may not continue to be operated without menace to the
public safety or when the boiler is found not to comply with the
rules herein provided for, and a special inspector shall have corres-
ponding powers with respect to inspection certificates for boilers in-
sured by the company employing him. Such suspension of an inspec-
tion certificate shall continue in effect until such boiler shall have
been made to conform to the rules and regulations of the Board of
Boiler Rules and until said inspection certificate shall have been
reinstated.

Sec. 2. And be it further enacted, That this Act shall take effect
