2 Testing.

2.1       Testforcorridorsshouldbeperformedinreducedvisibilityusingtheatrical(white)smoke with an Optical Density at least OD 0.5 m-1*.  Measuring equipment shouldconformtoastandard acceptable to the Administration.

 

2.2       Ifthesystemistobeinstalledinpublicspaces,thetestshouldbeperformedinreduced visibility using theatrical (white) smoke with an Optical Density at least OD 0.1 m-1.

 

2.3       Test for stairway enclosures should be performed in clear (no smoke) conditions.

 

2.4       Aminimum80%oftheparticipantsshouldreachthepre-designatedexitwithaspeedof movementofatleast0.7m/scalculatedusingthedistancemeasurementoftheoptimumroute. Participantsachievingaspeedofmovementofless than 0.7 m/s should be deemed to have failed. There is no speed of movement criterion applied to stairway enclosure tests.

 

2.5       Themaximumpercentageofparticipantschoosingfailedexitsshouldnotexceedthevalueof 2% for public spaces and 5% for accommodation areas, corridors and stairway enclosures.

 

2.6       Inthepublicspaceconfigurationwhentestingwithtwocorrectexits,nomorethan15%of the participants may choose the more distant exit.

 

2.7       Thereshouldbeaminimumof60participantsfor each test - being at least 8 and not more than  12  of  each  age  group  16-25,  26-35,  36-45,  46-55,  56-65,  66-75  with  an  average  of 45-55% male/female of the entire group.

 

2.8       A “control”testshouldbeperformedwithnoguidancesysteminoperationinorderto demonstratethatthereisnosignificantinherentbiastofavourthepre-designatedexit.  Participants of the “control” test should not participate in any previous or subsequent tests.

 

2.9       For the purpose of this section:

.2         participantsarrivingatanyofthe “failexits”aredeemedtohave “failed”thetestand should be stopped at that point;

.5         during the test signage other than those being part of the test should not be used.

5 Approval.

All systems should be approved by the Administration for compliance with the Performance standards for evacuation guidance systems (MSC⁄Circ.1167) developed by the Organization and, for electrically powered systems, IEC 60092 Electrical Installations in Ships. Installation requirements should be included in the approval procedures, and individual onboard arrangements should be verified accordingly.

6 Maintenance.

6.1 All elements of the system should be visually examined and checked at least once per week, and a record thereof should be kept. All missing, damaged or inoperable elements should be replaced.

6.2 All systems should have their signal tested at least once every five years. Readings should be taken on site. Should any reading be found to be outside manufacturers tolerances, then that element of the system should be replaced.
