Related Documents: DEF STAN 02-154; DEF STAN 08-123; see also Annex A.

1.1 General

a. Prior to the design of a new locker, consideration should be given to either usingan existing locker, or stowage of the explosive store in an appropriate magazine.

b. Except where otherwise indicated, the design and construction requirementsfor Magazine Lockers, Readyuse (RU) Magazine Lockers and DetonatorLockers shall be as described in this Section 3.

1.2 Environmental Conditions

a. The following environmental conditions (in accordance with the requirementsof DEF STAN 08123) shall be met in the design of all weatherdeck lockers:

(1) Sea States - The locker shall withstand, without failure, the maximumsea states the vessel will meet in its design role;

(2) Green seas loading - The requirements of DEF STAN 02154 shall be metin full;

(3) Solar radiation - The locker shall be designed to withstand the maximumthermal emission from solar radiation, which is equivalent to a heat fluxof 1120 W/m2 acting for a period of four hours. This will cause atemperature rise of approximately 20C on the exposed surfaces ofequipment;

(4) Salt corrosion - Lockers exposed to a saltladen environment,e.g. weatherdeck lockers, shall be designed to prevent corrosion;

(5) Wind effects - Lockers shall be designed to:

(a) Remain safe and be capable of acceptable performance in a relativesteady windtoship speed of 28 m/s with gusts of 1 minute durationof 40 m/s;

(b) Survive and remain safe in a relative steady windtoship speed of30 m/s and gusts of 1 minute duration of 54 m/s.

c. Explosive stores contained within RU Magazine Lockers shall remain safe afterexperiencing noncontact underwater explosion up to 70 per cent of themaximum ship shock level.

d. A figure of 70 per cent of the maximum ship shock level equates to a hull shockfactor of 0.91 for Destroyers and Frigates and of 1.2 for larger ships. Actualshock levels are derived by factoring the appropriate Grade Curve in BR 8470,normally Grade 1987D.

e. For lockers limited to a specific ship class, the Warship Project Manager (WPM),shall be consulted to ensure that the shock levels in Clause 3.1.3d. areappropriate.

3.1.4 Electrical Screening

a. The need for Electromagnetic Pulse (EMP) and Radio Frequency (RF)screening shall be evaluated when designing new or replacement Magazine andRU Magazine Lockers.

3.1.5 Response to Attack on Ammunition

a. The need for Response to Attack on Ammunition (RATTAM) protection in thelocker structure shall be evaluated when designing new or replacementMagazine lockers.

3.1.6 Insulation/Cladding Plates

a. All Magazine and RU Magazine Lockers (excluding Detonator Lockers) that areexposed to direct sunlight (i.e. Upper Deck Lockers) shall be insulatedinternally to prevent condensation. All lockers manufactured from metallicmaterials and exposed to direct sunlight shall also be fitted with external solarcladding plates over the top and sides. Lockers sited close to a bulkhead do notrequire cladding plates on the side adjacent to the bulkhead.

b. The internal insulation shall be made from 19 mm thick Phenolic Foam. It shallbe secured by adhesive bonding or studding on all faces, excluding the base.(A suitable insulation is available from MOD under NS No 0414/9679594).

c. When fitted, the Solar Cladding plates shall stand off by 25 mm from the topand sides of the locker to allow a free passage of cooling air. (See Clause 4.3.1a.).


10

3.1.7 Radar Cross Section (Radar Echo Area)

a. Lockers sited on the weatherdeck are wherever practicable to be designed forthe reduction of Radar Cross Section (RCS).

3.1.8 Radar Absorbent Material

3.1.9 Welding

a. All welding practice shall conform to the requirements of DEF STAN 02706.

3.1.10 Galvanizing

a. All Mild Steel components shall be hot dip galvanized in accordance with therequirements of BS EN ISO 1461.

3.1.11 Painting

b. `DETONATORS' shall be marked in Fire Retardant white paint across thefront of the locker in accordance with DEF STAN 02183 Part 1 or Part 2 asapplicable.

3.1.11.2 External Coatings

a. Unless stated on the relevant locker SDN then the following shall apply:

(1) Magazine Lockers and RU Magazine Lockers sited on the weatherdeckshall be prepared in accordance with the requirements ofDEF STAN 02759 and they shall be painted with two coats ofweatherwork grey undercoat to DEF STAN 80187, colour number 637followed by two coats of topcoat to DEF STAN 80165, colour number 676applied in accordance with the requirements of DEF STAN 02758.

4.3 Composite Material

a. Consideration shall be given to the use of materials which will preclude thenecessity for the physical shaping of lockers to reduce RCS. (See also Clauses3.1.8a., 3.1.9a. and Section 3).

b. The following Clauses define the methods of construction of compositemanufactured lockers.

4.3.1 General Construction

a. The use of composite materials in the locker carcass obviates the requirementfor solar cladding.

b. The use of a polyester laminating resin system in accordance with DEF STAN02 167 shall be employed.

c. Where required, a linear PVC thermoplastic foam shall be used as the coreinsulation material in composite lockers.

d. Where required, a Radar Absorbant Material (RAM) material shall be bondedinto the outer skin of the locker carcass.


15

4.3.2 Locker Carcass

a. The carcass shall preferably be produced in one piece.

b. The carcass shall be constructed by first laying in the external skin of the lockerand curing it.

c. The external faces of the locker shall be moulded on a former.

4.3.3 Locker Coatings

a. The surfaces of lockers manufactured from composite materials may bepainting or self coloured as follows:

(1) Painting: Surfaces shall be suitably prepared and painted withundercoat and a finish topcoat as stated in Clauses 3.1.11.2(1), 3.1.11.2(2)and 3.1.11.3a.

(2) Self Colouring: Internal and external surfaces shall be coloured by theintroduction of pigment into the Laminate/Gel coat to achieve the desiredcolour. The amount of pigment used shall be the minimum required toachieve the required colour and shall be no greater than 5 per cent of theresin/pigment mix by mass.

HazardClassification Code

A UN system by which explosive stores may be grouped forstowage purposes by Hazard Division and Compatibility Group,amalgamated together as Hazard Class Code BR 862, Chapter 5,Annex A refers.

Locker The suffix `locker' indicates that it is a free standing structuresurrounded by an air gap on all sides and that it is capable ofbeing bolted on to the ship's seating or on to deck pads. A lockerdoes not have an adjacent compartment because of this air gap. Afree standing locker may be recessed into the ship's structure butits boundaries are not part of the ship's structure. A locker is ofsuch a shape or size that it does not permit `walkin' access andthe contents are handled while standing outside the locker.

Magazine Locker Is a selfcontained freestanding locker designed to be safe for thepermanent stowage of the whole or part of the ship's outfit of thedesignated explosive store(s).

Readyuse MagazineLocker

Is a selfcontained freestanding locker designed to be safe for thetemporary stowage of small amounts of boxed or unboxedexplosive stores. It is to be sited near the weapon it serves, tofacilitate supply when the relevant armament is required to be ina `state of readiness'.
