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.

Introduction

This document is intended to provide means of evaluating and determining the maximum evacuation

capacity of marine evacuation systems (MES). As a consequence of MES systems being installed on large

passenger ships, there has been an increase in system capacity during recent years. This document

provides a uniform test regime while reducing the risk of injury to test personnel by reducing the

number of persons required to complete the test. The capacity determined through this document is

based on trial conditions as described in referenced IMO instruments and does not take into account

factors such as adverse weather conditions, ship-specific installations or arrangements, or the physical

capabilities of the passengers to be evacuated.

The MES retaining and connection lines of the test rig shall be arranged and fitted as on a real ship with

the same installation height and longitudinal distances as used for the capacity test.

4.5 Associated survival craft

If the capacity test includes the use of associated survival crafts, these shall be positioned on the pier at

a distance of at least 15 m from the centreline of the access entrance to the MES passage.

If more than one associated survival craft is used with the system, at least two of the largest associated

survival crafts necessary to attain the maximum capacity of the system shall be deployed and handled

during the test.
4.6 Access to embarkation area

The test rig should have a dedicated assembly area. However, other arrangements are acceptable if

access by the evacuees to the embarkation point, in a safe and constant flow, is ensured.

5 Test persons
5.1 Number of test persons

5.1.1 The number of persons to be selected for the test shall correspond to at least 110 % of the

capacity of the largest survival craft used with the MES, except as specified in 5.1.4.

5.1.2 In the case where a survival craft unit or units are used, a number of test persons corresponding

to 110 % of the largest individual survival craft shall be used, except as specified in 5.1.4.

5.1.3 In the case where only a single survival craft is used, of which the capacity is less than 165

persons, a number of test persons corresponding to 100 % of the survival craft shall be used.

5.1.4 If the survival craft capacity is larger than 165 persons, only 165 test persons shall be used and

the test shall be conducted under the conditions described in 6.8.
5.2 Selection of test persons
5.2.1 Subjects shall
— be able-bodied,
— not have received practical training in the use of a MES, and

— be selected according to the weight distribution given in Table 1 and the following.

5.2.2 Small test subjects, i.e. those persons less than 65 kg, need not be adults.

Weight range, kg

10 %–20 % 60 %–80 % 10 %–20 %
6 Test procedure

6.1 The test persons, wearing approved lifejackets conforming to the requirements of the LSA Code,

shall be lined up in the embarkation area, if space permits, or on the stairway leading to the embarkation

area in a way that there shall not be any interruption in the flow of the test persons.

6.2 Prior to initiating the test, the MES crew shall be ready in the embarkation area and awaiting the

order to deploy the system.

6.3 When the order to initiate the test is given, the timing is started and the system is activated by the

MES crew.

6.4 When the floating platform or the survival craft at the base of the passage is ready for boarding and

the access passable, the designated MES crew descends the MES and prepares to receive the test persons.

6.5 For safety reasons, the timing may be temporarily interrupted at this point while the test

persons assemble in the embarkation area and shall be resumed when the test persons are lined up as

described in 6.1.
6.6 If the MES consists of more than one passage, they shall be used equally.

6.7 When the all-clear signal is given, the test persons descend to the floating platform/survival craft

and transfer to the survival craft which is designated as the first to be disengaged from the system.

6.8 If either a single survival craft or survival craft unit is used as described in 5.1.4, the following

procedure is used as equivalent to verify operational capabilities in a crowded survival craft.

6.8.1 If a single survival craft is used, the test persons shall assemble in the area closest to the end

of the passage closest to vessel connection points to simulate that the operating area for the crew is

crowded.

6.8.2 If a survival craft unit is used, the test persons shall assemble in the craft(s) closest to the end of

the passage(s) and in such a way that at least one craft is occupied to its full capacity.

6.9 The handling of associated survival craft may be carried out in parallel with the descent of the test

persons, provided that the MES crew is available to perform all operations safely.

6.10 When the last survival craft to be used for the test is disengaged, the time is stopped.

7 Test timing
7.1 Timekeepers

7.1.1 The role of the timekeeper(s) shall include, but is not limited to, the following:

a) ensuring all stopwatches to be used to record event timings are synchronized;
4 © ISO 2016 – All rights reserved
---------------------- Page: 9 ----------------------
ISO 16707:2016(E)
b) ensuring all timed operations to be recorded can be viewed;

c) ensuring that if there is more than one timekeeper, each time keeper is aware of their individual task;

d) recording of test times as detailed in Table 2;

e) recording the capacity of the floating platform/primary raft(s) as applicable;

f) recording the capacity and boarding sequence of associated survival craft as applicable;

g) recording the number of MES crew used during the test and the positions of MES crew as relevant.

7.1.2 The use of video cameras appropriately synchronized can be used to assist in recording the

timing of the key events of the evacuation, if necessary.
7.2 Sequences to be timed

7.2.1 Prior to the initiation of the test, all stopwatches shall be synchronized and set to 0:00. When the

signal to initiate the test is given, the timekeepers shall start their stopwatch(s). The timekeeper(s) shall

record the time at which each of the events indicated in Table 2 occur. The time recorded shall be the

time shown on the stop watch when the event occurs.
7.2.2 Depending on the design of the MES, and the number of
