1、Designation: D6117 18Standard Test Methods forMechanical Fasteners in Plastic Lumber and Shapes1This standard is issued under the fixed designation D6117; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A
2、 number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONThe use of plastic lumber and shapes often involves the use of mechanical fasteners, such as nails,screws, bolts, lag screws, and conn
3、ectors. Data on the strength and performance of such fasteners arefrequently needed for design and for comparative purposes. Presented herewith are methods ofconducting tests for nail, staple and screw withdrawal resistance and lateral load transmission by nail,staple, screw, and bolt. The use of st
4、andard methods for these tests is recommended as a means ofobtaining comparable data and of eliminating variables in test results because of variation in testingmethods.1. Scope*1.1 These test methods cover the evaluation of fastener usewith “as manufactured” plastic lumber and shapes through theuse
5、 of two different testing procedures.1.2 The test methods appear in the following order:SectionsTest Method ANail, Staple, or Screw Withdrawal Test 4 to 13Test Method BLateral Nail, Staple, or Screw Resistance Test 14 to 221.3 Plastic lumber and plastic shapes are currently madepredominately from re
6、cycled plastics. However, these testmethods would also be applicable to similar manufacturedplastic products made from virgin resins where the product isnon-homogeneous in the cross-section.1.4 The values stated in inch-pound units are to be regardedas standard. The SI units given in parentheses are

It is theresponsibility of the user of this standard to establish appro-priate safety, health, and environmental practices and deter-mine the applicability of regulatory l

Scope4.1 This test method provides a basic pr
20、ocedure for evalu-ating the resistance or plastic lumber and shapes materials todirect withdrawal of nails, staples, and screws. Spikes areincluded as nails in this test method.4.2 This test method also provides a basis for determiningcomparable performance of different types and sizes of nails,stap
21、les, and screws in direct withdrawal from plastic lumberand shapes.5. Summary of Test Method5.1 Specimens consist of “as manufactured” plastic lumberand shapes, with nails, staples, or screws driven at right anglesto one or more faces. The fasteners are withdrawn at a uniformrate of speed by means o
22、f a testing machine, and the maximumload is recorded. Supplementary physical properties of theplastic lumber and shapes are also determined.6. Significance and Use6.1 The resistance of plastic lumber and shapes to directwithdrawal of nails, staples, or screws is a measure of its abilityto hold or be
23、 held to an adjoining object by means of suchfasteners. Factors that affect this withdrawal resistance includethe physical and mechanical properties of the plastic lumberand shapes; the size, shape, and surface condition of thefasteners; the speed of withdrawal; physical changes to plasticlumber and
24、 shapes or fasteners between time of driving andtime of withdrawal; orientation of fiber axis; the occurrenceand nature of prebored lead holes; and the temperatures duringinsertion and withdrawal. These factors will be as circum-stances dictate, and representative of the normal manufacturingprocess.
