14.5 FUNCTION TEST AND SERVICE
PRE - SEASON BINDING INSPECTION
The procedure that follows is an integral part of pre - season maintenance.
It is also a good way to determine if maintenance is adequate and which
units have outlived their usefulness and must be removed from inventory.
1. Clean areas of the bindings that contact the boot and perform
all pre - season binding maintenance.
2. Visually or manually check:
a. AFD condition
b. Brake function
c. Release indicator readability and travel
d. Screw tightness
3. Fit each binding to the reference boot and adjust the release
indicators to the value in Table [A].
4. Check that the heel track and toe track single code agree with
the sole length single code of the reference boot.
5. With the reference boot in the binding, verify elastic travel of
the toe piece by striking the boot toe with a mallet or dead
hammer and checking that the toe piece returns the boot
quickly and completely to center.
6. Verify elastic travel of the heel piece by lifting the boot while
depressing the heel piece cocking lever and checking that the
heel piece returns the boot quickly and completely to the latched
position.
7. Manually release the binding 3 times in each direction.
8. Lubricate all boot / binding interfaces with a mild liquid detergent
and water solution.
9. With the ski binding test device determine the release Torque
for each direction of release (forward lean and both directions
in twist).
10. Record " PASS " in the binding's maintenance record if test
results are within the inspection ranges provided in table [A].
11. Set the ski aside if the test result in any directions of release is
outside the inspection range in table [A].
12. Follow trouble - shooting procedure ( 12.4) for units which
have been set aside and retest if changes in the unit's condition
or adjustment are made.
13. Record " FAIL " in the binding's maintenance record if, after
trouble - shooting, test results in any direction of release are
outside the in - use range. Replace the " failed " unit and retest
before returning the ski to service.
14. If after trouble - shooting, test results are outside the inspection
range but within the in - use range, apply a correction
factor to the unit and note the correction factor for that unit in
the binding's maintenance record.
15. If many bindings fail, check the test device and re - inspect the
reference boot. If necessary, select another boot and retest
the bindings.

PRE - SEASON BOOT PREPARATION
The procedure that follows is an integral part of pre - season maintenance.
1.
Clean all boots with a mild detergent and water, and repair or
replace damaged or missing parts.
2. Visually check:
a. Conformance with ISO and other applicable standards - ISO
5355. If the boot contacts the binding, brake, or AFD in
areas other than the designated contact points, it may be
incompatible with the binding.
b. Boot material. If the sole at the contact points with the binding
or AFD can be scratched with a finger nail, the boot may be of
inferior quality and incompatible with the binding.
c. Boot sole condition. If the boot sole is damaged, worn, or
contaminated at contact points with the binding or AFD in a
manner which cannot be corrected, the boot may be incompatible
with the binding, ( 2.3) " Verify boot sole dimensions " .
d.
Brake compatibility with sole.
e. Rubber and / or metal sole protectors. If such materials
contact the binding or AFD the boot may be incompatible
with the binding.
f. Mold flashings. Flashing which can be seen or felt at contact
points with the binding, brake, or AFD must be carefully
removed.
3. Remove from inventory all boots that have failed the visual check.
PRE - SEASON BOOT SAMPLING
Although sampling eliminates the need to test every boot before the season
starts, the sample chosen must be representative of the inventory.
1. For boots that are new to inventory or have never been inspected,
take a single boot from each cell (a cell is all boots of the same make,
model, year, and shell size).
2. For used boots, take a 5 % (but not less than 16 or more than 80)
random sample of the entire inventory, see table [B]. Make sure
that there is at least one boot from each cell in the sample.
