TO 1-1-700 5.27 METHOD 40 - WATER VAPOR PROOF PROTEC- TION. See AFPAM(I) 24-237, Chapter 4, for application procedures. 5.27.1 Concept. This is a water vapor proof enclosure in which the items, with or without a preservative coating, are placed. The enclosure may be a rigid container or a water vapor proof barrier, depending on the method being developed. The sub-methods under Method 40 are: • Method 41 - Water vapor proof bag, sealed. • Method 42 - Container, water vapor proof bag, sealed, container. • Method 43 - Floating water vapor proof bag, sealed. • Method 44 - Rigid container (other than metal), sealed. • Method 45 - Rigid metal container, sealed. 5.27.2 Intended Use. It is intended to afford protection to metallic and non-metallic items against deterioration caused by water or water vapor and by natural or industrial contaminates and pollutants. 5.27.3 Critical Parts. When critical functioning metal surface parts and equipment require close tolerances, Method 40 can be supplemented with contact preservatives. 5.27.4 Usage Without Contact Preservation. This method was originally intended to prevent corrosion on metal parts, but can also be used without a contact preservative to keep fabric, paper, plastic, and other non-metallic items clean and dry during shipment and storage. 5.28 METHOD 50 - WATER VAPOR PROOF PROTEC- TION WITH DESICCANT. See AFPAM(I) 24-237, Chapter 4, for application procedures. 5.28.1 Concept. Items protected in accordance with this method shall be sealed in a water vapor proof enclosure with activated desiccant as required for the specific sub-method of this group. A humidity indicator should be use with the packs unless otherwise stated in the contract or order. 5.28.2 Sub-Method Requirements. There are five submethods of this method which can be used. The following general requirements apply to all sub-methods: • Items shall be sealed in a water vapor proof enclosure with activated desiccant. • Unit packs shall include a humidity indicator. • Methods 50 labels will be applied to unit packs (see Figure 5-8). • Items shall be cushioned as required to mitigate shock, thereby preventing physical and functional damage to the item. • When bags are used, the sealed edge of the bag that would normally be opened for item inspection shall be of sufficient surface area to permit two subsequent resealing after item inspection, unless otherwise specified. 5.28.3 Sub-Methods of Method 50. The five sub-methods of Method 50 are: • Method 51 - Water vapor proof bag, sealed. • Method 52 - Container, water vapor proof bag, sealed, container. • Method 53 - Floating water vapor proof bag, sealed. • Method 54 - Rigid Container (other than metal), sealed. • Method 55 - Rigid metal container, sealed. 5.28.4 Intended Use. This method is used for items of a highly critical nature which require the highest degree of protection from damage by the effects of water vapor. It is applicable to mechanical or electrical items including assemblies with functional components which, because of their nature, cannot be treated with a preservative. This method is not used on any item where the withdrawal of moisture would cause damage to the item. 5-14
TO 1-1-700 CHAPTER 6 MOISTURE AND FUNGUS PROOFING 6.1 GENERAL. The following moisture and fungus-proofing requirements are furnished to enable inspecting personnel to determine quality and acceptability of repaired equipment. Consult Appendixes A and B of TO 1-1-691 for information on materials and equipment required for these procedures. 6.2 DETAILED REQUIREMENTS. The following materials will be treated as specified in this manual prior to assembly on electronic equipment and will need no additional varnish coverage. 6.2.1 Leather. Examine leather items such as bags, cases, belts, etc., for wear, torn seams, stains, fungi, etc. Leather is highly prone to attack by mold, mildew, and fungus. 6.2.1.1 Repair all torn seams with MIL-T-713, Type N, Class 3 wax impregnated twine mildew proofed per MIL-T-3530, Type I, Class 2. Use No. 301 lock stitches per ASTM-D-6193. 6.2.1.2 Remove paint (lacquer and enamel), ink, or other similar marking materials applied by field units for identification purposes as follows: 6.2.1.4 Wipe off all standing water from the leather surface and allow it to air dry for 40 minutes if subsequent treatment is required, treat with Type I mildew preventive leather dressing compound. O-L-164, DRESSING, LEATHER 55 NOTE O-L-164, Type I Leather Dressing compound is available through GSA in a 5 gallon can under NSN 8030- 00-221-0665. a. Mix one part of O-L-164, Type I leather dressing compound by volume into 5 parts by volume of clean water. Preferably, application will be by immersing leather items in the solution and stirring and/or tumbling them for 10 minutes. When immersion is impractical due to inclusion of critical parts on a leather item, application of solution may be made with a soft bristled brush, felt dauber or cloth. b. Allow treated leather to dry in open air. ASTM D 329 (PART NO. O-A-51), ACETONE 11 a. Dampen a cloth with ASTM D 329 (O-A-51) acetone and lay it on the area from which the marking materials are to be removed. b. Allow the dampened cloth to remain in contact with the area until marking material has softened. c. Remove softened marking material by scraping, rubbing or brushing with a toothbrush with medium stiffness bristles. Clean leather items with a mild soap and water solution at a temperature not to exceed 100 °F (38 °C) applied with a cloth followed by brushing with a toothbrush with medium stiffness bristles to remove any remaining dirt. 6.2.1.3 Rinse with clean water at a temperature between 75 °F (24 °C) and 100 °F (38 °C) applied with a cloth. Under no condition shall olive drab paint be used to paint canvas or duck items. 6.2.2 Canvas and/or Duck. Examine canvas or duck items for wear, torn seams, stains, fungi, etc. Those considered to be still serviceable will be processed as follows: a. Repair all torn seams with either 10/3 or 12/4 cotton thread conforming to Commercial Item Description (CID) A-A-52094, Type II. NOTE These threads are available through the Air Force supply system in 16 oz. tubes and olive drab in color under NSN 8310-00-262-2782 for the 10/3 thread and NSN 8310-00-197-7757 for the 12/4 thread. b. Wash items in a washing machine or other device in which canvas and/or duck items are tumbled in a solu- 6-1
