Technical Background
UR E10 (Rev.4) IACS WP/EL Task No.49 To clarify the equipment to be covered by UR E10 Type Test Specification and to investigate the adequacy of the DC power supply tests in item 4 Power supply variations of the table in UR E10. Objective and Scope:
1. To redefine more closely the equipment to which E10 is required to be applied.
2. To investigate if the test procedure for DC power supply voltage variation in item 4 a) of the Table Type testing condition for equipment covered by E10.1 is adequate.
Source of Proposed Requirements: IACS UR E10 (Rev. 3, May 2001) Draft of AHG/COMP Onboard Use and Application of Computers. IEC Pub. 60092-504 Points of Discussion: There appears to exist different interpretations among IACS member societies for the scope of applications of E10 for onboard equipment and systems, especially for onboard computer based systems and peripherals. At least, further breakdown of the listed equipment in E10.1 is necessary for uniform implementation of E10 among IACS member societies. The existing UR E10 had undergone an extensive review during the meeting. ABS proposed to postpone this objective due to several reasons taking into account of the currently undergoing Tasks in IACS, e.g., L[5], AHG/COMP, AHG/EMC, etc. However, during the discussion, it was decided that the scope of application in E10.1 was slimmed and the application of E10 was limited for Type Approval. NK submitted the investigation of the test procedure for DC power supply voltage variation in item 4 of the Table of E10. It appears that the duration time and the cycle period for voltage cyclic variation and voltage ripple are not specified for the test conditions of DC supply variation. However having considered all pro et contra after discussion it was decided to stay tests without change as it is. Additionally it was proposed to investigate some suppositions in EMC/AHG. It was decided to approve new Draft of UR E10 on following conditions:
To change Type Test Specification in title and para.E10.1 of UR E10 to Test Specification for Type Approval.
To retain monitoring, control protection and safety and interior communication services and to delete all other services in the current E10.1.
To stay voltage cycling variation and voltage ripple (para.4 of E10 Table) without change as it is.
With some other changes the corrected draft of the UR agreed by WG was forwarded to GPG for consideration attached to the 33rd WP/EL Progress Report.

Technical Background
E 15(Rev.1, 2004)
IACS WP/EL Task No.60 To revisit the Unified Requirements E15 to facilitate uniform implementation, by further clarification of the intent of the requirements including development of the definition of fire zone and deck. Objective and Scope: To revisit the requirements and notes in UR E15 Electrical Services Required to be Operable Under Fire Conditions and Fire Resistant Cables taking into consideration the various arrangements and possibilities for maintaining electrical services under fire conditions. Particularly, to develop definitions, practicability of maintaining the functionality, etc., as may be necessary to further clarify the intent and improve the uniform application of E15 in the area as indicated under Work Specification. Background for the Proposed Revision: Since the adoption of UR E15 in May 1999, various shipbuilders sought (and are still seeking) clarifications as to the interpretation of UR E15 including the following issues: (a) A fire zone can mean anything between main vertical/horizontal zones in
SOLAS Reg. II-2/2.2.1 and any single space listed in SOLAS Reg. II-2/2.3.3 or 2.4.2. Reference to high fire risk area earlier in E15.2.1 suggests the latter approach may be closer to the intent, which needs to be clarified. Reference to decks could be superfluous when fire zone is properly defined. It could be even misleading without reference to bulkhead, another element consisting the boundary of zone or area.
(b) E15.3.1 suggests that services in E15.2.2 may not be supplied under local fire at an apparatus. This could contradict E15.2.2 when read literally.
(c) There is room for further refinements, including but not limited to duplicated system in the second paragraph of E15.2.1 (PA system is a single system with duplicated elements so as to maintain functionality see LSA Code 7.2.2.1, a system with supply from main and emergency sources is another example.), apparatus in E15.3.1 (undefined), etc.
Points of Discussion: It is considered that the confusion has been caused by the terminologies of deck and the undefined fire zone in E15 since there are various arrangements of cables for electrical services to be operable under fire conditions. Re-investigation was mainly made for the following points: (a) Correction to follow the latest IEC Standards for fire resistant cables in
E15.1, (b) Requirement for distinguishing the fire resistant cable from flame retardant
cables or other non-fire resistant cables in E15.1, (c) Clarification of the original intent in E15.2.1 taking into account of the
practicable application, (d) Development of the definition for high fire risk areas in E15.2.1, (e) Revisiting the list of services in E15.2.2, (f) Refining E15.3.1 for further clarification of the original intent, and
-
(g) Several editorial corrections. It was also investigated if Section 1 subclause 4 of IEC 60092-352 (1997) should be incorporated in E15, which states In circuits used for fire alarm, detection, extinguishing services, remote stopping and similar control circuits, fire resistant cables shall be considered unless the systems are self-monitoring type or failing to safety or the systems are duplicated. However, it was concluded that the above statement is not included in E15 revision since it is not the intent of E15.2.1. The wording provided their functionality can be maintained in the second paragraph of E15.2.1 was deleted since it is not considered practicable to maintain the functionality after the cables to these services are damaged. However, if the system failure is detected and alarmed under self-monitoring functions, the crew can recognize the failure and would establish the compensating routines or procedure. Further, the system fails to a safe mode and duplicated with cable runs are also compensating such failure. Note: DNV GPG Member suggested that E15.1 should also refer to IEC 60331-21 for cables with diameter of less than 20 mm. E15.1 was so amended.

Installation of electrical and electronic equipmentin engine rooms protected by fixed water-basedlocal application fire-fighting systems(FWBLAFFS)
Definitions:
Protected space:
- Is a machinery space where a FWBLAFFS is installed.
Protected areas:
- Areas within a protected space which is required to be protected by FWBLAFFS.
Adjacent areas:
- Areas, other than protected areas, exposed to direct spray.- Areas, other than those defined above, where water may extend.
See also Fig. 1
Unless it is essential for safety or operational purposes, electrical and electronic equipment is not to be located within areas protected by FWBLAFFS and in adjacent areas where water may extend.
The electrical and electronic equipment located within areas protected by FWBLAFFS and those within adjacent areas exposed to direct spray are to have a degree of protection not less than IP44.
Electrical and electronic equipment within adjacent areas not exposed to direct spray may have a lower degree of protection provided evidence of suitability for use in these areas is submittedtaking into account the design and equipment layout, e.g. position of inlet ventilation openings,filters, baffles, etc. to prevent or restrict the ingress of water mist/spray into the equipment. Thecooling airflow for the equipment is to be assured.
Note
1. Additional precautions may be required to be taken in respect of:
a. tracking as the result of water entering the equipmentb. potential damage as the result of residual salts from sea water systemsc. high voltage installationsd. personnel protection against electric shock
Equipment may require maintenance after being subjected to water mist/spray.

UR E 20 (New, 2004)
IACS WP/EL Task 52 Influence of fixed water-based local application fire-fighting systems (FWBLAFFS) in engine rooms to electrical equipment Objective and scope: To develop UR for the electrical safety of electrical and electronic equipment within engine rooms, in areas protected by FWBLAFFS, and adjacent areas where water may extend. Source of proposed requirements. SOLAS Ch. II-2 / 10.5.6.2 MSC Circ. 913 MSC Circ. 1082 Points of discussion Increasingly, water-based fire-fighting systems are being used in engine rooms, control rooms and other spaces, as well as for local application, which when activated may have an extremely destructive effect on electrical equipment. In this context an essential requirements contained in IMO document MSC Circ. 913, clause 3.2, should be noted: The activation of the fire-fighting systems should not result in loss of electrical power or reduction of the maneuverability of the ship. WG considered the possibility of damage to some electrical equipment due to the operation of FWBLAFFS. The potential for damage depends upon a number of factors, which include:
1. Various types of available FWBLAFFS and their potential effects on electrical equipment within their vicinity.
2. Requirements for the installation of FWBLAFFS in machinery spaces in respect to adjacent electrical equipment.
3. Degree of ingress protection for electrical equipment in these areas with regard to the type of FWBLAFFS used. (e.g. low and/or high pressure systems etc.)
4. Voltage at which the equipment operates (low voltage vs. high voltage systems).
5. Location of the electrical equipment and enclosure inlets relative to the water mist nozzles.
6. Mist droplet size and droplet density (which can vary substantially from manufacturer to manufacturer depending upon their particular nozzle design).
Each of the above items directly impact the potential for damage to electrical equipment, and it would therefore appear that all such items must be adequately quantified before establishing any reasonable conclusions regarding the potential damage to electrical equipment. Beyond the potential damage to electrical equipment, it would appear that the potential danger of shock would also be of significant concern. During the XXV WP/EL Meeting it was decided to make some definitions concerning with areas protected by FWBLAFFS where electrical equipment are installed. Taking into account the aforesaid WP/EL developed this Unified Requirement, which was agreed by WG and forwarded to GPG for consideration attached to the 33rd WP/EL Progress Report.
