Dear Mr. Kahmann:
This responds to your letter dated July 23, 1976, asking whether accessory test equipment is
subject to 49 CFR Parts 192 and 195.
There are no specific regulations governing accessory test equipment in 49 CFR Parts 192 and
195. However, if accessory test equipment is installed in a pipeline (including pipe, valves, and
other appurtenance attached to pipe, compressor units, pump stations, metering stations,
regulator stations, delivery stations, holders, and fabricated assemblies) as a physical facility
through which gas or liquid move in transportation, then it is subject to the general requirements
governing design, construction, operation, and maintenance of a pipeline. We suggest that you
contact the operators who purchased the accessory test equipment you manufacture to determine
whether or not the equipment is used as part of a pipeline.
Thank you for your interest in pipeline safety.
Sincerely,
Cesar DeLeon
Acting Director
Office of Pipeline
Safety Operations

Attention: Cesar De Leon, Director
Gentlemen:
We are manufactures of Dead-Weight Pressure Measuring Instruments. These instruments are
used both in the construction and operation of gas and product pipelines, for exact pressure
determinations.
We have received orders from some of our customers requesting that instruments we furnish
them "meet all of the applicable provisions of the Department of Transportation Minimum Safety
Standards".
We have reviewed Federal Regulations Title No. 49, Section 192 and find no specific reference
to accessory test equipment. We would appreciate assistance from your office directing us to the
specific Sections of the Law that would apply to our equipment. Any pertinent excerpts you
might forward to us would be appreciated.
Thank you.
Very truly yours,
CHANDLER ENGINEERING COMPANY
A. R. Kahmann
