3.15.2 Attachment/detachment of ILJS. At no time shall the attachment/detachment of the ILJS
from the container and during any operational scenario require an individual to be on top of or
beneath the container. The following human engineering requirements shall apply to ISO
containers located on the ground.
3.15.2.1 Attachment of ILJS. Each corner jack assembly shall be attached to the container in not
more than ten minutes. The attachment of the ILJS to the container shall not require an individual
on top of or beneath the container.
3.15.2.2 Detachment of ILJS. Each jack shall be detached from the container and broken down
to the shipping mode with common hand tools in not more than ten minutes.
3.16 Reliability. The ILJS shall have a specified reliability of not less than 0.98 when subjected to
the operational cycle specified in 3.9.7 and 3.9.8. A failure analysis shall be performed in
accordance with test requirements specified in 4.4.4.9.
3.17 Maintainability. Total active maintenance, including driver/crew checks and services, shall
be not greater than 15 minutes per operational cycle (see 3.9.7 and 3.9.8). Preventive
maintenance shall not be required at intervals of less than 12 months or 55 cycles, whichever
comes first.
3.18 Cleaning, treatment, and painting. ILJS surfaces shall be blast cleaned in accordance with
SSPC-SP19, treated and painted as specified herein. Surfaces to be painted shall be cleaned and
dried to ensure that they are free from contaminates such as oil, grease, welding slag and splatter,
loose mill scale, water, dirt, corrosion products, or any other interfering substances. As soon as
practicable, after cleaning, and before any corrosion product or other coating-interfering material
can result, the surface shall be prepared or treated to ensure adhesion of the coating system.
3.18.1 Painting. Painting of ILJS surfaces shall consist of at least one coat of primer and at least
two finish coats. The primer shall conform to MIL-P-53022 and shall be applied to a clean dry
surface as soon as practicable after cleaning and treating. The dry film thickness of the primer
shall be not less than 1.5 mils (0.0381 mm) over the entire surface. Paint for the finish coat shall
conform to MIL-C-46168, green 383, type IV. The dry film thickness of each applied coat shall
be not less than 1.8 mils (0.0457 mm) over the entire surface. The dry film thickness of the finish
coat shall be not less than 3.6 mils (0.0914 mm) over the entire surface. The total dry film
thickness of the finish coat shall be not less than 5.1 mils (0.1295 mm) over the entire surface.
The paint shall be free from runs, sags, orange peel, or other defects.
3.19 Lubrication. Unless otherwise specified (see 6.2), means for lubrication shall be in
accordance with the manufacturer's standard practice. The lubricating points shall be easily
visible and accessible. Hydraulic lubrication fittings shall be in accordance with SAE J534.
Where use of high-pressure lubricating equipment, 1,000 pound-force per square inch (psi)
(6 895 kilopascal (kPa)) or higher, will damage grease seals or other parts, a suitable warning
shall be affixed to the equipment in a conspicuous location.
