10、 in use. The Visitors Specs shall be individually packaged in clear plastic packaging material. 2. Shelf Life: The EWARP shall have a shelf life as packaged for a minimum period of 24 months. 3. Performance Requirements: Prior to the application of EWARP, the piping system shall be at an ambient tem
11、perature in the range of 60 to 90 degrees fahrenheit. No media shall be flowing through the piping section being repaired. EWARP shall be used independent of augmenting materials such as boiler sealing compounds or rubber gasket material. The pipe surface shall not be cleaned, other than to remove l
12、oose rust and scale and jagged or protruding edges around the rupture. The rupture size shall not exceed 0.75 square inches for compressed air, hydraulic fluid and lubricating oil, and 3 square inches for fresh and salt water. The EWARP shall be removed from the hermetically sealed pouch and presoak
13、ed in fresh or salt water for not more than 20 seconds. No more than one (1) pack of size 1 and two (2) packs of size 2 EWARP shall be applied to the pipe. The EWARP shall solidify in not less than 5 minutes and not more than 15 minutes within this temperature range. The EWARP shall be allowed to cu
14、re for 30 minutes. After 30 minutes, the EWARP shall be cured to the point that full pressure of 150 lb/in2 can be applied to the pipe without leakage within this same temperature range. Qualitv assurance. The EWARP shall be of the highest quality and shall be free from contaminants, foreign, or ext
15、raneous matter which will affect the performance of the EWARP. Unless otherwise specified in the contract, the contractor is responsible for the performance of all quality inspections of the EWARP. The government reserves the right to perform any First Article Inspections and require First Article T
16、esting ta assure that supplies conform to prescribed requirements. 2 Licensed by Information Handling Services - A-A-50434 47 7779774 0057377 5 M i A-A-504 3 4 1. Health Requirement: When the EWARP is used in combination with air, fresh water, salt water, hydraulic fluid, or lubricating oil, its fum
17、es shall have no adverse effect on the health of personnel when used for its intended purpose. Neither should the EWARP present any unusual problems that would require more protective equipment than Visitors Specs and gloves. 2. Safety Requirement: Material Safety Data Sheets (MSDS) in accordance wi
18、th the Occupational Safety and Health Administration (OSHA) Hazard Communication Standard 29 CFR 1910.1200 shall be provided to point of delivery for each case of EWARP. Cases not containing an MSDS will be returned. 3. TDI and MDI Certification: Prior to award of the contract, the manufacturer shal
19、l provide certification that Toluene Diisocyanate (TDI) has not been used in the formulation of the EWARP, and that the airborne levels of diphenylmethane diisocyanate (MDI) released during normal use of the EWARP do not exceed 0.02 PPM (or current permissible exposure criteria) ceiling value as sti
20、pulated by Title 29 Code of Federal Regulations, Part 1910.1000. Certification that TDI is not present, and the MDI airborne levels shall be made by a board certified Industrial Hygienist, based upon laboratory results obtained from an analytical laboratory accredited by the American Industrial Hygi
21、ene Association. The method of sampling and analysis shall be approved by the National Institute for Occupational Safety, and Health. A standard amount of one (1) pouch of size 1 and two (2) pouches of size 2 EWARPs must be applied for each sample, and a sufficient number of samples shall be taken t
22、o document on a statistical basis that the safe exposure limits of MDI do not exceed 0.02 PPM (or current permissible exposure criteria) as a ceiling value in the breathing zone.
