Chemcast Bullet Resistant SheetFile BP8756 December 5, 1996 Report Plastiglas de Mexico S.A. de C.V. TEST RECORD NO 1 Samples: Five sample of Model Chemcast BR material rated for Level 1 were submitted by the manufacturer and subjected to the following test program. BALLISTICS TEST: General: The ammunition used for the investigation was 124 grain (8g), 9 mm full metal copper jacket with lead core, minimum velocity 1175 fps (358 mps). SUPPLEMENTARY SHOTGUN TEST: All tests were conducted at close range, approximately 15 ft (4.6 m), using the ammunition and weapon specified. The test samples were mounted in a rigidly fixed frame, with 1/8 in. (3.2 mm) thick corrugated cardboard indicator panels placed approximately 18 in. (467 mm) behind the protected side of each test sample. During the test, each bullet velocity was monitored and recorded. The samples were subjected to three different shot patterns: 1-shot edge, 2-shot and 3-shot. The 1-shot edge pattern consists of mounting a sample in a frame with the lower edge unsupported and struck with a single shot placed midway between the vertical supports and 1 to 1-1/2 in. (25.4 to 38.1 mm) from the unsupported edge. The 2-shot pattern consists of two shots fired at the approximate center of the test sample, with the shots spaced between 1-1/4 to 1-3/4 in. (31.8 to 44.5 mm) apart. For both the 1-shot and 2-shot patterns, spalling of bullet-resisting material from the protected side of the test sample is acceptable. However, there shall be no penetration of the projective through the material such that damage to the indicator panels occurs, nor breaking apart of the sample which allows an unobstructed path for additional projectiles through the sample. The 3-shot pattern consists of three shots spaced at +/- 1/2 in. (102 +/- 12.7 mm) apart in a triangular pattern in the approximate center of the test sample. With this shot pattern, there shall be no penetration of projectiles through the test sample, nor spalling of the material on the protected side of the test sample, to the extent that fragments embed in or damage the cardboard indicators. OUTDOOR RATING: Five samples were subjected to various ambient conditions. Three separate samples at room temperature, 22 +/- 3 degrees C (72+-/ 5 degrees F), were subjected to the 1-shot edge, 2-shot and 3-shot patterns. A fourth sample, after exposure to a temperature of 49 degrees C (120 degrees F) for a period of 3 h to the complete sample, and a fifth sample after exposure to -32 degree C (-25 degrees F) to the side receiving the shots for a period of 3 h were subjected to the 3-shot pattern. The samples were tested immediately following the exposure to the indicated temperature conditions. The velocity of each bullet was recorded during the test. The velocity values as recorded for multiple shot tests consist of the first value of the 2-shot pattern being the top point, and the second being the bottom point, the first value of the 3-shot pallet is the top point of the triangle, with the next values going in a clockwise direction around the triangle. RESULTS Acceptable results were recorded for all shot patterns at all ambient conditions as outlined above. LEVEL 1
DESCRIPTION PRODUCT COVERED: Bullet resisting glazing material Model Chemcast BR, Level 1. ENGINEERING CONSIDERATIONS (NOT FOR FIELD REPRESENTATIVES' USE): The product is bullet-resisting glazing material intended for use indoors and out-of-doors.
