ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

2⋅g
n
where
g is the standard acceleration of free fall in metres per square second;
n
v is the maximum tripping speed of the safety gear expressed in metres per second;
0,1 corresponds to the distance travelled during the response time, in metres;
0,03 corresponds to the travel during take-up of clearance between the gripping elements and the
guide rails, in metres.
The total energy the safety gear is capable of absorbing is calculated with Formulae (2) and (3):
2⋅=KP +Qg⋅⋅h (2)
()

K is the energy absorbed by one safety gear block, in joules (calculated in accordance with the chart);
P are the masses of the empty car and components supported by the car, i.e. part of the travelling
cable, compensation means (if any), etc., in kilograms;

Measurements a) and b) shall be recorded as a function of the time.
4.3.3.1.1.2 The following shall be determined:
a) the average braking force;
b) the greatest instantaneous braking force;
c) the smallest instantaneous braking force.
4.3.3.1.2 Test procedure
4.3.3.1.2.1 Safety gear for a single mass
Four tests with the mass (P + Q) shall be carried out. Between each test, the friction parts shall be allowed
to return to the ambient temperature.
If during the tests, the friction parts are replaced, each set shall be capable of:
a) three tests, if the rated speed does not exceed 4 m/s;
b) two tests, if the rated speed exceeds 4 m/s.
The height of free fall shall be calculated to correspond to the maximum tripping speed of the safety gear.
The engagements of the safety gear shall be achieved by a means allowing the tripping speed to be fixed
precisely.
4.3.3.1.2.2 Safety gear for different masses
Where adjustment is in stages or continuous, two series of tests in accordance with 4.3.3.1.2.1 shall be
carried out for:
a) the maximum; and
b) the minimum values applied for.
A formula or a chart shall be provided showing the variation of the braking force as a function of a given
parameter.
The validity of the supplied formula or chart shall be verified by one series of tests for a linear chart or two
