UL 187 Document Information:
Title
UL Standard for Safety X-Ray Equipment
Underwriters Laboratories Inc.
Publication Date:
Apr 30, 1998
Scope:
These requirements cover X-ray equipment for medical, commercial, and
industrial use to be employed
in accordance with the National Electrical Code.
These requirements cover enclosed equipment intended for connection to
supply circuits of 600 V or
less, including controls, high-voltage transformers, tube units, and
similarly related components
such as foot switches, bucky diaphragms, tables, tube stands,
tube-head cooling units, tube
protectors, stereo-shifters, cassette changers, spot-film devices,
camera stands, photo-tube
detectors, timers, and the like, which are directly concerned with the
generation and application
of X-radiation. X-ray equipment intended for use in a hazardous
location is investigated under
these requirements and, in addition, is investigated with respect to
its acceptability for the
particular application.
These requirements do not cover allied apparatus such as film viewers
and similar accessories,
which are covered by other applicable requirements. These requirements
do not cover equipment in
which the radiation is obtained from radioactive isotopes.
Except for equipment not used for medical or dental diagnosis or
treatment - such as cabinet
equipment, baggage inspection systems and the like - these
requirements do not contemplate the
investigation of protection against X-radiation except as noted in
48.1.
A product that contains features, characteristics, components,
materials, or systems new or
different from those covered by the requirements in this standard, and
that involves a risk of fire
or of electric shock or injury to persons shall be evaluated using
appropriate additional component
and end-product requirements to maintain the level of safety as
originally anticipated by the
intent of this standard. A product whose features, characteristics,
components, materials, or
systems conflict with specific requirements or provisions of this
standard does not comply with
this standard. Revision of requirements shall be proposed and adopted
in conformance with the
methods employed for development, revision, and implementation of this
standard.
