Panasonic Toughbook Mobile
Computers are MIL-STD-810F Compliant
Each
Panasonic Toughbook® is designed and manufactured to meet a level of
durability matched to an intended work environment. The range of
Toughbooks cover the ruggedized Toughbook 18, Toughbook 27, Toughbook
29, Toughbook 34, Toughbook 01, Toughbook 07 and MDWD (Mobile Data
Wireless Display), and include models with selected durability features
like the remaining semi-rugged models.
At the very least, each Toughbook features a
magnesium alloy LCD case, 20 times stronger than ABS plastic, to protect
this critical and expensive-to-replace component. Other models include
full magnesium cases to protect all system components. Hard disk drives
are equipped with various degrees of shock insulation to protect
mission-critical data from the dangers of shocks, bumps and drops. Some
Toughbooks also offer spill-resistant keyboards to provide protection
from the spills and splashes that are a frequent part of mobile
computing environments.
The key to choosing the right Toughbook is
to consider your work environment and your performance and feature needs
- your Panasonic representative or reseller will help you understand
which Toughbook is the right choice for your particular business
requirements.
Reliability
Our most rugged Toughbooks have been designed using MIL-STD-810F
test procedures to measure levels of environmental reliability. Created
by the U.S. government, the MIL-STD-810F specifications cover a broad
range of tests that measure the durability of equipment used under harsh
conditions. From the MIL-STD-810F test menu, Panasonic selected those
that most closely reflect the challenges that mobile professionals face
in the field, on the road, and in the office. These tests include drop-,
shock-, moisture-, dust- and vibration-resistance, exposure to extremely
low and high temperatures, and many others.
Passed the Test
And even though Panasonic conducts these environmental tests in
our own factories with our own equipment, we didn't stop there. After we
finished our in-house tests on the ruggedized Toughbook 18 , Toughbook
27 and Toughbook 29, we gave it to one of the leading independent
environmental test agencies in the United States to repeat all of the
tests again. In the end, the results confirmed our own: the Toughbook 18
, Toughbook 27, Toughbook 28 and Toughbook 29 passed all challenges
without failure.
Testing Procedures
And while not every Toughbook is designed to be as ultra-rugged
as the Toughbook 18, Toughbook 27, Toughbook 28, Toughbook 29 or
Toughbook 34, tests like the MIL-STD-810F help us to understand how to
design all of our Toughbooks with the best focus on durability features
for the type of user and work conditions. The information below
describes the tests we use to measure Toughbook durability.
MIL-STD-810F Test Procedures
The following MIL-STD-810F test procedures
were performed on the Toughbook 28:
Drop Test
The Drop test was performed in accordance with MIL-STD-810F,
Method 516.5, Procedure IV (Transit Drop Test). The Toughbook 28 was
sequentially dropped in non-operating mode, onto each face, edge and
corner for a total of 26 drops from a height of 36 inches. The drop
surface was defined as two-inch-thick plywood over a steel plate over
concrete. The Toughbook 28s were visually inspected after each drop and
a functional check (boot-up into Windows) was performed after each drop.
Results
The Toughbooks boot Windows® following each drop.
Vibration
The Vibration shall be performed in accordance with MIL-STD-810F,
Method 514, Procedure I, Category 24 (Minimum Integrity Test) for the
non-operational condition and Category 20 (Ground Vehicles) for the
operational condition. The unit should be clamped to an aluminum plate
(approximating rigid mounting), and subjects to the following levels of
vibration:
Non-Operational (from Figure 514.5C-17
of MIL-STD-810F) 0.04 g2 /Hz at 20-1000 Hz, -6 dB/Octave at 1000-2000
Hz, 1 hour/axis duration.
Operational (Figure 514.5C-1 of MIL-STD-810F) 0.001 g2 /Hz at 12.5 Hz,
0.034 g2 /Hz at 20~40 Hz 5.70E-06 g2 /Hz at 200 Hz, 1 hour/axis duration
simulating 1000 miles of transportation.
The hard disk drive was spinning during the operational test. A
functional test was performed between each axis of testing, to catch any
potential failures. The operational test was conducted using the
vertical axis power spectral density (worst case condition for
amplitude), as the orientation of the test item during transportation is
not known.
Results
All units passed the vibration test without incident.
Water Resistance
The Water Resistance test was performed in accordance with
MIL-STD-810F, Method 506.4, Procedure III (Drip). The test items were
subjected to this test with the LCD open and the unit operating, but
with ports closed. The Toughbooks were opened following testing to
inspect for water intrusion.
Results
The Toughbooks continued to operate during and following the 15-minute
water drip test. There was no evidence of water intrusion.
Humidity
The Humidity test was performed in accordance with MIL-STD-810F,
Method 507.4 (Aggravated). The test items were tested for operation near
the conclusion of the fifth and tenth cycles. Each cycle was one day (24
hours) and the entire test was performed over ten days.The temperature
was cycled between 86 and 140°F with the relative humidity at 95%
constant.
Results
The Toughbooks continued to boot up and operate following each test, and
there were no visual anomalies.
Dust Resistance
The Dust Resistance test was performed in accordance with
MIL-STD-810F, Method 510.4, Procedure I (Dust). An operating temperature
of 140°F was used for this test. The upper non-operating temperature of
140°F was incorporated into the test as this is the "default"
temperature given by the MIL-STD-810F guidelines. Silica flour as
defined by the test standard was used. Failure was considered to have
occurred if moving parts bind or are blocked, or if contacts or relays
malfunctioned. The units must have continued to function also.
Results
The Toughbooks continued to operate following dust testing. The
keyboards were usable.
High Temperature
High Temperature tests were conducted in accordance with
MIL-STD-810F, Method 501.4, Procedures I (Storage) and Procedure II
(Operation). Panasonic set the testing parameters as follows: 140°F
Operational, 160°F Non-Operational
Results
The Toughbooks continued to operate during the operational test and to
boot and operate following the non-operational test. There were no
visual anomalies.
Low Temperature
The Low Temperature test was performed according to MIL-STD-810F,
Method 502.4, Procedures I (Storage) and II (Operation). Panasonic set
the low operating temperature at -20°F and non-operating temperature at
-60°F.
Results
The Toughbooks continued to boot and operate following each test, and
there were no visual anomalies.
Thermal Shock
The Thermal Shock test was performed in accordance with
MIL-STD-810F, Method 503.4. Panasonic set the high temperature
non-operating temperature at 205°F and the low temperature non-operating
temperature at -60°F. Three cycles were performed (high to low = one
cycle).
Results
The Toughbooks continued to operate during the operational test and to
boot and operate following the non-operational test. There were no
visual anomalies.
The Toughbooks continued to boot up and
operate following the test exposure cycles of thermal shock from 205°F
to -60°F.
Altitude
The Altitude test was performed in accordance with MIL-STD-810F,
Method 500.4, Procedure I (Storage) and II (Operation). The altitude
level used for both procedures was 15,000 feet (highest equivalent
altitude given within MIL-STD-810F for cargo pressures of military
aircraft)
Results
All Toughbooks passed the test without incident.
Full details of each test are contained in a
test report that was produced by an independent, internationally
recognized test laboratory.
