Climatic and Dynamic Environmental Ruggedness
The sections that follow summarize the climatic and dynamic environmental tests suites.
Introduction
Models 743, 744 and 748 are designed for use in an environment that involves moderately
high and low temperatures, humidity variations, and occasional vibration. Many of the test
limits the workstations are subjected to during development are more severe than those docu-
mented.
The tests were developed to cause product failure so that product weaknesses are identified,
understood, and eliminated, when possible and to provide greater assurance of long-term
compliance to product specifications.
An effective qualification program establishes appropriate assurances. Our development and
manufacturing process capabilities are well understood.
Significant quantities of Models 743, 744, and 748 were tested prior to release for volume
production. Representative samples of customer-shippable workstations were tested in vari-
ous configurations through the environmental tests to evaluate corner-case conditions.
NOTE: Presentation of these test suites does not imply a guarantee of product performance, nor a
guarantee of performance to these levels by the entire population of Models 743, 744, and 748
computer systems.
