Summary of Automotive Tank Environmental Compliance Testing
ATPD 2352 determines performance requirements for transparent armor. This transparent armor is used for windows of armored ground military vehicles and other Army structures. Transparent Armor (TA) is the technical term for protective transparencies. TA is also commonly known as ballistic-resistant windows.
ATPD 2352 Regulatory Compliance Test Procedures
The Transparent Armor is examined for allowable defects specified per each procedure. Nonconformance to any of the requirements below will classify as a failure.
The transparent armor must meet the allowable defects requirements per MIL-810 Method 501 and MIL-STD-810 Method 502. This is conducted from temperatures as low as -54 C to 71 C. For high temperatures, the Transparent Armor is subjected to three 24-hour cycles.
Equipment subjected to the humidity conditions of ATPD 2352 must meet allowable defects and optical requirements after being subjected to five cycles of temperature-humidity exposure. The humidity test is conducted in accordance with MIL-STD 810 Method 507.
Temperatures for the five cycles may vary from 30 C to 60 C at a relative humidity of 95%. These cycles run for 0 to 48 hours.
MIL-STD 810 Method 503 describes this standard’s thermal shock test procedure. The surrounding air temperature ranges from -30 C to 60 C. The minimum temperature stabilization period is 18 hours at each temperature extreme.
The test cycle may begin at either extreme. The transfer time between temperature conditions is no longer than 5 minutes. The armor is subjected to five cycles. After testing, the unit is stabilized at ambient conditions for a recommended period of 24 hours.
Transparent armor assemblies must be free of bubbles, delamination, cracking, and internal clouding after the completion of twelve cycles of a specified accelerated life profile. If any of the defects mentioned have dimensions greater than 25 mm, the transparent armor has failed the test.
The test is conducted on two assemblies. Next, the units are set vertically in a test chamber with the acceptable steady state temperature and relative humidity at 3 C and 5%, respectively.
