1、Designation: F 1429 99 (Reapproved 2009)An American National StandardStandard Test Method forAssembly Force of Plastic Underground Conduit Joints ThatUse Flexible Elastomeric Seals Located in the Bell1This standard is issued under the fixed designation F 1429; the number immediately following the de
2、signation indicates the year oforiginal adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This test method covers the
3、determination of the relativeforce required to assemble plastic underground conduit jointsthat use flexible elastomeric seals located in the bell.1.2 The values stated in inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are

It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-
5、bility of regulatory limitations prior to use.2.

The chartrecorder receives input from the
7、 testing machine in the form ofelectrical signals that are proportional to the test readings.3.1.3 gasketed conduit joining systema push-on conduitjoining system (see joint, push-on in Terminology F 412) withthe following three manufacturer-specified components thatinfluence joint assembly force: (1
8、) the elastomeric seal, (2) thechamfer on the spigot, and (3) the joint lubricant. This systemis as supplied or recommended by the conduit manufacturer.4. Summary of Test Method4.1 A sample of eight gasketed conduit bells of the samenominal diameter are prepared from typical production stock ofthe c
9、onduit manufacturer. An aluminum spigot mandrel madeto the specifications of Annex A1 for the conduit size beingtested is inserted into each of the eight gasketed conduit bellspecimens by means of a compression tester and the jointsystem assembly force is recorded for each specimen. Themean and stan
10、dard deviation of the sample of eight recordedassembly forces is then calculated and recorded.4.2 Any variation in the type of gasket, spigot chamfer, orjoint lubricant specified by the manufacturer constitutes achange in the gasketed conduit joining system and requires thata new sample of eight spe
11、cimens be tested.5. Significance and Use5.1 The assembly force of a conduit joining system is onemeasure of the ease of which the conduit system can beassembled and installed in the field. This test method providesa means by which to quantify the assembly force of gasketedconduit joining systems. Th
12、e results of the testing can be usedto compare and categorize the assembly force of differentdesigns of gasketed conduit joining systems.5.2 This test method is not intended for use as a qualitycontrol test.5.3 This test method can be used for comparison of gasketedconduit joining systems on the bas
13、is of assembly force. Noinformation about joint sealing performance can be obtainedfrom the use of this test method.1This test method is under the jurisdiction of ASTM Committee F17 on PlasticPiping Systems and is the direct responsibility of Subcommittee F17.40 on TestMethods.Current edition approv

16、he bell toprovide the joint seal.5.5 This test method is also applicable to all fittings that arefabricated from conduit covered in 5.4 and that utilize the sametype of push-on joints as the conduit covered in 5.4, and thatare intended for use with the conduit types described in 5.4. Forpurposes of
17、this test method, assembly force data obtainedfrom the testing of the conduit that is the parent stock of afitting shall apply to the fitting also.6. Apparatus6.1 Testing MachineA properly calibrated compressiontesting machine of the constant-rate-of-crosshead movementtype meeting the requirements o
18、f Testing Method D 695 shallbe used to make the tests. The compression tester shall becapable of a compression rate of 20 6 0.5 in./min (500 6 12.7mm/min). The compression tester shall be equipped with achart recorder that is capable of recording compression forceversus time or position.6.2 Spigot M
19、andrelsSpigot mandrels shall be constructedto mount rigidly to the compression tester. The mandrels shallconform to the dimensions and specifications shown in AnnexA1.6.3 Joint LubricantJoint lubricant shall be used prior tothe assembly of the conduit joints. It shall be as specified orsupplied by t
20、he conduit manufacturer, or both.7. Test Specimens7.1 Specimens shall be comprised of a conduit bell with anelastomeric seal.7.2 Specimens shall have no less than 1 in. (25 mm) and nomore than 3 in. (76 mm) of nominal conduit diameter extend-ing past the bottom of the bell shoulder (see Fig. 1).7.3
21、The bottom of each specimen (spigot end) shall be cutperpendicular to the axis of the bell barrel within 61 (see Fig.1).7.4 Bell dimensions and specifications shall be determinedby the bell manufacturer, but the specimens shall be represen-tative of normal and customary production by the manufac-tur
22、er.7.5 Test specimens can have any standard wall thickness. Itis not necessary to test more than one wall thickness pernominal conduit size.7.6 Number of Test SpecimensThere shall be eight speci-mens to be tested for each design of gasketed conduit joiningsystem and nominal conduit size.8. Condition
23、ing8.1 Condition specimens, spigot mandrels, and joint lubri-cant for at least 8 h in air at a temperature of 73 6 7F (23 64C) prior to testing. Begin testing immediately after condi-tioning period.8.2 Conduct the testing in a room maintained at the condi-tioning temperature.9. Procedure9.1 Select e
24、ight bell specimens of the same nominal sizewhich have been prepared and conditioned according toSections 7 and 8 of this test method.9.2 Mark the specimens with consecutive numbers, startingwith “1” and ending with “8.”9.3 Rigidly mount the proper spigot mandrel for the nomi-nal size of conduit bei
