Introduction
This manual establishes uniform methods for testing electronic
and electrical parts including basic environmental, physical
and electrical tests. These tests were developed to support
IPC standards and specifications.
The tests described herein are not to be interpreted as an
exact and conclusive representation of actual service opera-
tion in any one geographic location, since it is known that the
only true test for operation in a specific location is an actual
service test at that point. The specified test conditions for a
test method are those, which are obtainable in the laboratory
and result in reproducible results.
No attempt has been made to include pass/fail criteria in the
test methods. This information is found in the individual speci-
fications and standards that reference the specific test
method.

All
equipment used for performing or supporting the tests shall
be calibrated before being put into service. The test facility
shall have an established program and procedure for the
regular calibration of its equipment.
A calibration program should include a system for selecting,
using, calibrating, checking, controlling and maintaining mea-
surement standards, reference materials used as measure-
ment standards and measuring and test equipment used to
perform tests described in this manual.

Three
main elements must be considered in planning how to
obtain test data at room ambient conditions. These are:
1. The set-up for supporting and operating the test equip-
ment.
2. The instrumentation for measuring the data from the tests.
3. The instrumentation for measuring and recording room
conditions at the time of the test.
This last factor is important when comparing test data
obtained at different times or facilities. In most cases, this step
consists of simply recording the barometric pressure, relative
humidity and temperature at the time of the test. If other con-
ditions are found to have a significant impact on the test data
these conditions should be recorded as well.
Unless otherwise specified in the applicable test method, indi-
vidual standard or specification, all laboratory ambient tests
shall be made under the following conditions:
1. Temperature: 15 °C to 35 °C [59 °F to 95 °F]
2. Relative Humidity: 35 % to 75 %
Whenever these conditions must be closely controlled to
obtain reproducible results or for referee purposes, tests shall
be conducted under the following conditions:
1. Temperature: 22 °C±3°C[72°F±5°F]
2. Relative Humidity: 50%±10%
