In paragraph 31.8.3, the reference to 31.1 should be to Table 31.1. 2. The proposed Table 31.1 should be noted as a revision to the existing Table 31.1 rather than a new table. 3. In Table 31.2 and in the Tensile breaking strength and elongation row, under Exposure the two conditionings should be shown as two separate paragraphs for clarity. 4. In Table 31.2 and in the Visual clarity row, under Exposure the two conditionings should be shown as “1. Weathering 500 KJ/ (m2 nm) 340 nm of accelerated Xenon weathering. and 2. Abrasion conditioning, in two separate paragraphs for clarity. 5. In Table 31.2 and in the Visual clarity row, Under Test method there are two items that should be shown as two separate paragraphs corresponding to the two exposures, for clarity “1. See weathering specifi cations in Table 2.2” and “2. Method 5304 of FTMS 191A. See 31.8.2” 1. ACCEPT. The proposal will be revised accordingly. 2. ACCEPT. The changes to Table 31.1 will be indicated by underlining.3.ACCEPT. The proposal has been revised accordingly. 4.ACCEPT. The proposal has been revised accordingly. 5.ACCEPT - The proposal has been revised to include the suggested changes. RATIONALE Through a U.S. Coast Guard funded grant we have approved two polyvinyl chloride (PVC) and fi ve vinyl window materials for use on hybrid infl atable PFDs and fully infl atable PFDs. The thickness of these approved materials ranges from 0.012 to 0.180 inches. Five of these materials have been tested and approved for being sewn to cover fabric material. While seven specifi c materials provide a range of approved components, it would be inappropriate not to have a test procedure available for other manufacturers to use to gain like approval. This proposal was based on U.S. Coast Guard guidelines and if approved will establish new requirements that will allow other window materials to be tested and accepted for use on hybrid and infl atable PFDs. As the result of comments received on the balloting of the Indicator Window Material proposal (PR 604) several revisions have been made to the proposal. Please see comments and responses in the table above. Paragraph 31.8.3 has been revised to reference Table 31.1 instead of paragraph 31.1. Table 31.1 has been revised to underline the changes balloted. Several requirements have been added to the exposure and test method specifi cations in Table 31.2.

The tension of the samples shall be maintained throughout conditioning. 31.8.3 The visual clarity tests, in accordance with 31.8.3.1 31.8.3.3, shall be used to determine if infl ation system indicators are correctly distinguishable over the viewing range described in Table 31.1 when viewed through the window material after Xenon weathering and abrasion conditioning, 31.8.4 For the visual clarity tests in 31.2, a minimum of two samples for each direction lengthwise and widthwise, shall be cut to 230 by 48 mm (9 by 1-7/8 inch). 31.8.5 The compliance with the visual clarity of the window material shall be determined by a qualifi ed observer capable of correctly distinguishing the red/green indicators prior to the mounting of the window material. 31.8.6 The viewing apparatus for the visual clarity test shall consist of two representative infl ation mechanisms, one indicating red and the other indicating green, mounted in a fl at panel. The infl ation mechanism shall be mounted so that its outside is fl ush with the outside of the panel. The window material samples shall be mounted directly over the infl ation mechanism with the conditioned surface area directly over the indicator. The viewing apparatus shall be placed at a distance of 2 meters (6.5 feet) from the observers eyes and the infl ation mechanism indicator at a height equal to the observers eyes when seated. The apparatus shall be capable of movement through the full viewing range as specifi ed in 31.1. The light source shall be a 40 watt incandescent daylight bulb placed at a height of 1 meter (3.25 feet) directly over the observers head. The test shall be performed in a dark non-refl ective environment (no visible light when the 40 watt incandescent daylight bulb is not lit).
