This International Standard specifies construction, performance, and testing requirements for thermal protective aids (TPA's) with sleeves, complying with the IMO Life-saving Appliances Code (LSA Code) for carriage on SOLAS ships and in survival craft on SOLAS ships in compliance with the International Convention for the Safety of Life at Sea (SOLAS) 1974, as amended.

The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards.

For the purposes of this International Standard, the following terms and definitions apply.

　

components of the TPA provided to allow for closure and/or adjustment of the device, i.e., zippers, hook and loop fasteners, drawstrings, etc.

　

the portion of the TPA which individually covers the arms and hands of the wearer

4.1.1 The fabric or film used in the construction of the TPA shall be of a durable insulating or heat reflecting waterproof material that meets the thermal insulation requirements in 5.1.

　

4.1.2 The TPA shall be designed to cover the wearer's entire body, except for the area of the mouth, nose, and eyes.

　

4.2.1 Stitching, if used in structural seams of the TPA, shall be lock type stitching in accordance with ISO 4915:2000, class 300 - lockstitches.

　

4.2.2 Each type of seam shall have a strength of at least 225 N when tested in accordance with 6.2.4.

Where used, all hardware of the TPA shall be of a size and design that allow ease of operation by the wearer. The hardware shall be attached to the TPA in a manner that allows the wearer to operate it easily and that prevents it from attaining a position in which it can be operated improperly.

Each metal part of a thermal protective aid shall be demonstrated to be resistant to salt water and salt air corrosion, and be galvanically compatible with each other metal part in contact with it.

The primary color of the exterior surface of each thermal protective aid shall be vivid reddish orange.

　

When tested in accordance with clause 6.2.5, the TPA shall have a tear resistance of at least [45 N].

The TPA shall be provided with sleeves that allow sufficient dexterity for the wearer to close and open the zipper or other hardware of the TPA and to open and eat typical approved survival rations. The hand portion of the sleeve may not be removable unless it is attached to the sleeve and unless it can be secured to the sleeve or stowed in a pocket on the sleeve when not in use.

[The TPA shall be fitted with at least 200 cm²of approved Type I retro-reflective material complying with IMO Res. A.658(16), positioned on the upper part of the TPA so as to enhance visibility either in the water or while seated in a survival craft.]

4.9.1 The TPA shall fit persons ranging in weight from 50 kg to 150 kg, and in height from 1.5 m to 1.9 m.

　

4.9.2 Each TPA shall be designed so that a SOLAS lifejacket can be worn inside it and, when worn, will not damage the TPA and will not adversely affect its performance.

Each TPA shall be provided with suitable sealed waterproof packaging.

4.11.1 Each TPA shall be provided with instructions for its donning and use in an emergency. The instructions shall be in the appropriate language or languages and shall not exceed 50 words. Pictographs shall be used in addition to or instead of the words. The instructions shall include advice as to whether to swim in the TPA or discard it if the wearer is thrown into the water.

　

4.11.2 The instructions shall be printed on the exterior of the packaging, printed on a waterproof card attached to the packaging, or printed on the TPA and visible through transparent packaging. The instructions shall also be available in suitable loose-leaf format for inclusion in the ship's training manual.
