ASTM D2444-99(2005)

Standard Test Method for Determination of the Impact Resistance of Thermoplastic Pipe and Fittings by Means of a Tup (Falling Weight)

SIGNIFICANCE AND USE
The impact resistance of thermoplastic pipe and fittings relates to suitability for service and to quality of processing. Impact resistance may also provide a relative measure of a material’resistance to breakage during handling and installation and, for non-buried applications, to in-service breakage. See Appendix X4 for guidelines for selecting testing combinations.  
Results obtained by use of this test method can be used in three ways:  
3.2.1 As the basis for establishing impact test requirements in product standards,  
3.2.2 To measure the effect of changes in materials or processing, and  
3.2.3 To measure the effect of the environment.
SCOPE
1.1 This test method covers the determination of the impact resistance of thermoplastic pipe and fittings under specified conditions of impact by means of a tup (falling weight). Three interchangeable striking noses are used on the tup, differing in geometrical configuration. Two specimen holders are described.
1.2 The values stated in inch-pound units are to be regarded as the standard. The values in parentheses are provided for information purposes only.
1.3 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.

4.3.3 Means shall be provided (1) to hold the tup at steps of
2 in. (50.8 mm) for a distance of 2 to 10 ft (610 mm to 3.0 m)
above the specimen holder, (2) to release the tup in a
reproducible manner, (3) to allow the tup to fall freely, and (4)
to catch the tup on the first rebound. Refer to Fig. 1.
4.4 Specimen Holder—Two specimen holders are de-
scribed. The V-block (Holder A) is usually used with Tups A
and C; the flat plate (Holder B) is often used with Tup B or for
testing fittings.
4.4.1 The V-block holder shall be at least as long as the
specimen being tested and shall have a 90-deg included angle.
It may be fabricated or of solid construction. The side supports
shallbeofsufficientdepthtosupportthespecimenintheVand
not on the top edges of the V-block.
NOTE 5—Both aluminum and steel have been found suitable for the
holders.
4.4.2 The flat-plate holder shall consist of a plate approxi-
mately 8 by 12 by 1 in. (203 by 305 by 25.4 mm) in which a
groove to position the pipe specimen shall be cut. This groove
shall be about 0.12 in. (3 mm) in depth with the edges rounded
to a radius of about 0.06 in. (1.5 mm). Fittings that do not
contact the plate directly under the point of impact shall be
supported at this point by a flat steel plate or shim. The
specimen holder shall be mounted on a rigid base fastened to
a concrete slab. Means shall be provided to center the speci-
mens under the drop tube. A bar or rod pla
