Description

ASTM F736-95-Reapproved2011

Historical Standard: Standard Test Method for Impact Resistance of Monolithic Polycarbonate Sheet by Means of a Falling Weight

ASTM F736

Scope

1.1 This test method covers the determination of the energy required to initiate failure in monolithic polycarbonate sheet material under specified conditions of impact using a free falling weight.

1.2 Two specimen types are defined as follows:

1.2.1 Type A consists of a flat plate test specimen and employs a clamped ring support.

1.2.2 Type B consists of a simply supported three-point loaded beam specimen (Fig. 1) and is recommended for use with material which can not be failed using the Type A specimen. For a maximum drop height of 6.096 m (20 ft) and a maximum drop weight of 22.68 kg (50 lb), virgin polycarbonate greater than 12.70 mm (½ in.) thick will probably require use of the Type B specimen.

Note 1—See also ASTM Methods: D1709, D2444 and D3029.

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3.1 Exception—The inch-pound units in parentheses are provided for information only.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific hazard statement, See Section 7.
