14.5 FUNCTION TEST AND SERVICE
PRE - SEASON BOOT INSPECTION:
The procedure that follows helps to assure both boot / binding
compatibility and boot interchangeability. Note: when using table
[A],in the boot inspection procedures that follow, the sole length
and release indicator setting columns should be ignored.
1. Randomly select a pair of bindings that have passed the preseason
inspection from each binding type: adult, junior, child.
2. Lubricate all boot / binding contact points with a mild liquid
detergent.
3. Without regard to whether the boot is new or used, sort the
sample by sole type and length according to the 20 mm sole
length categories defined by the release / retention adjustment
chart.
4. In each sole length category rank the boots by sole length and
select the middle boot.
5. In each sole length category fit the appropriate reference
bindings to this „typical " boot and adjust the two bindings to
release as close as practical to the reference torque in table
[A]. Use the reference torque corresponding to skier code [L]
for the adult binding, [I] for the Junior binding, and [E] for the
Child binding.
6. Rinse the lubricant from one binding and mark it „clean. " Mark
the other „lubricated " .
7. Test each boot in the sole length category with the clean
reference binding and then the lubricated reference Binding
in both twist and forward lean (only one direction in twist is
required for the clean binding).
8. Set aside any boots for which the lubricated test result is
more than 20 % less than the clean test result in the same
direction of release or the Lubricated test result in any direction
of release is outside of the inspection range provided
in table [A] for the skier code used to set up the reference
binding (E, I, or L).
9. Repeat the visual check on all boots that have been set aside,
correct any defects noted, and retest. Remove from inventory
boots that fail the retest.
10. Check all other boots from the same cell (make, model, year,
and shell size) as those that failed.
NOTE:
On completion of the pre - season inspection, clean the liquid detergent
from the equipment and lubricate the binding before returning it
to service.
IN - SEASON SAMPLING AND INSPECTION:
The in - season inspection is a test of complete systems and all the
procedures used by the rental staff to assemble and adjust the
system. The program uses random samples of rental inventory taken
at routine intervals. Any sampling program that gives every unit of
inventory the same chance as every other of being picked is valid.
SAMPLE FREQUENCY:
Random sampling is conducted throughout the entire season.
FREQUENCY IS AS FOLLOWS:
1. After 7 days of operation.
2. If the sample passes the next sampling is taken after another 7
days of operation.
3. If two consecutive samples pass, sampling frequency is increased
to 14 days.
4. If a sample fails at any time, daily sampling is instituted until
two consecutive samples pass, at which point weekly sampling
resumes.
SAMPLE SIZE:
Sample size is 5 % of inventory but not less than 16 nor more than
80 units as noted in table [B]. Sample size is based on average daily
out-put. If rental output drops below 50 % of capacity over the sampling
period, the sample size can be reduced proportionately.
IN - SEASON INSPECTION:
1. Take a random sample of the rental inventory as determined by
table [B]. Take half of the sample from inventory as it is either
rented or returned and the remainder from inventory available
for rental.
2. The returned samples are tested with the last customer's
data, the other samples adjust to randomly selected skier data.
Consider already applied correction factors.
3. Wipe the boot clean and cycle the boot / binding systems at
least once in each direction.
4. Test sample units in twist (one direction only) and forward lean.
5. Compare the test results with the inspection range for the
appropriate skier code, see ISO 11088 release / retention
adjustment chart. (page 74/169)
6. If the results are within the inspection range, one value above to
one value below the reference value, the unit passes.
7. If the results are outside inspection range but within the in - use
range, two values above to two values below the reference
value, count the unit as a class I deviation.
8. If the results are outside the in-use range, count the unit as a
class II deviation.
9. Check elastic travel and visually inspect the ski brake function,
interface areas between boot and binding, including AFD, lug
height adjustment (if appropriate), and forward pressure. Count
any deficiencies as class I deviations.
10. If more than the maximum number of class I deviations given in
table B are found in the sample, or a single class II deviation is
detected the sample fails and daily sampling must be conducted
until the problem which led to the failed sample is found and
corrected.
11. Record the date the sample was tested, the number of units
tested, the number of class I and class II deviations, whether
the sample passed or failed and any actions taken. There is
no need to record the identity of units tested or actual test
results.
