ISO 8061:2004 pdf download – Alpine ski-bindings -Selection of release torque values.
4.2 Release torques corresponding to use?s maximum recommended mass
It the actual mass of the skier is greater than the maximum recommended mass for hisiher height, It, the release torque values shall be calculated using the maximum recommended mass, m1,,,, which is given by the equation
100 (It — 1)
for It) 1.50 m, where It is the height of the skier, in metres
4.3 Correction of the release torque
4.3.1 The recommended release torque values shall be corrected for skier-type (see Annex A) and age (see
4,3.2 and 4.31 respectively).
The result may be eventually lowered or raised upon request of the skier (see 4.3.4 and 4.3.5).
4.3.2 The skier-type correction factor should be
For skier type 1: —15% for M and 4i1y;
For skier type 2:0:
For skier type 3: +15% for 11z and My:
4.3.3 The age correction is determined as follows.
— Skiers under 10 years: —15% for .iI and M:
— Skiers aged 50 years and above: —15%for M1 and My;
4.3.4 Release torque values other than those recommended above may be used in the following cases:
a) Skiers who have satisfactory experience with lower settings regarding these recommendations may request settings based on their experience.
b) Skiers who have skiing experience without inadvertent releases may request a setting up to 15% lower than that recommended above.
c) Skiers having certain characteristics, such as a neutral skiing technique, defensive attitude, high degree of control, etc. may request a setting up to 15% lower than that recommended above.
d) Skiers who have experienced inadvertent releases may request a setting up 10 15% higher than that recommended above.
4.3.5 Skiers may request settings that are different tor twist and forward lean.
4.3.6 tIthe skiers style requires greater corrections than those indicated above, the skier may change the setting at his/her own risk.
A.1 Skier types
A.1 .1 It Is the responsdilily of the skier to determine hislher skier-type classitication as defined In Table A. 1.
A.1 .2 Skiers are classified by type of sking into three types, 1, 2 and 3. The definitions are as follows:
— Type 1: cautious skiing on smooth slopes of gentle to moderate pitch. This type also applies to entry-level skiers uncertain of their classification. Skiers who designate themselves as type 1 receive lower than average reteaseretentioi, settings. Tho corresponds to an increased risk of inadvertent binding release, in order to gain increased capacity for release in a tall.
— Type 2: skIers not classibed in type 1 or 3.
— Type 3: fast, aggressive skiing on slopes of moderate to steep pitch. Skiers who designate themselves as type 3 receive higher than average releaseretenbon settings. This corresponds to deczeased capacity or release in a fall, in order to gain a decreased risk of inadvertent bincng release.
Designations 1, 2 and 3 should not be used by equipment manufacturers to categorize their prockicts.
A.1.3 The information given in Table A.1 is an example of the kind of layout which may be used to assist me skier in determining his skier-type classification,
Table A.1 — DeterminatIon of skier-type classification
The information given in A.1 .2 can be used to assist the skier in determining the a
.cation and to make hirn1er aware of the risks related to each classification.
A.2 Discretionary settings
A.2.1 Skiers 10 years of age and older of any type who desire a higher or lower setting than the setting of their skier type according to 4.3.4 a), b). C) or d) may designate their preference with a – or — next to theE skier-type designation.
A.2.2 The use of these definitions in determining the release setting may be inappropriate for some types of competition skiing.
