2、t revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 These test methods cover instructions for making avariety of tests for the strength of the adhesive bond developedbetwee
3、n a steel anchor and the surface of a hole in concrete ormasonry (including masonry units and mortar joints) and forassessing the effects on such bond of a variety of factorsincluding elevated temperature, fire, moisture, and freezing andthawing action. The specifier or manufacturer shall select tho
4、setests that are appropriate for the given anchoring system andintended application.1.2 The adhesive-bonded anchor system refers to a smoothor deformed steel bar or threaded rod, set in a predrilled holecontaining chemical bonding compounds. Loads are trans-ferred mainly by the bond of the adhesive
5、both to the anchorand the surrounding elements along the sides of the hole. Foranchoring systems made of significantly different materials,these test methods shall be taken as a guideline.1.3 This standard applies to all adhesives used to bond steelanchors or steel reinforcement bars (rebar) to conc
6、rete ormasonry. These test methods apply to anchorages used inuncracked concrete or masonry. They do not apply to the use ofthe anchor in the concrete tension zone. The usual forcesapplied during the tests are in tension, shear, and under acombination of both tension and shear.1.4 The values stated
7、in inch-pound units are to be regardedas the standard. The SI units given in parentheses are forinformation only.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use.

21、Test Method E 488. All sizes are to be tested at both minimumand maximum embedments expected. Shear tests at the maxi-mum embedment shall be permitted to be excluded if sheartests at a shallower embedment result in a steel failure. If thereis a difference greater than 9 anchor diameters between thes
22、eembedments additional intermediate embedments shall betested. Clean holes and install anchors as specified by themanufacturer. Measure and record hole diameters and/or drillbit diameters. Install and cure anchors at 75F 6 10F (24C 65C).7.3 Dynamic Tests:7.3.1 Fatigue TestsPerform fatigue tests in a
23、ccordancewith Test Method E 488.7.3.2 Seismic TestsPerform seismic tests in accordancewith Test Method E 488.7.4 Environmental Tests:7.4.1 The tests given in Sections 7.4.3-7.4.8 are designed todetermine the effect of loading and environmental influenceson the bond strength of the adhesive. To ensur
24、e bond failure,use steel of sufficiently high strength to prevent steel failure ofthe anchor. To provide comparative standardized data, anchorsshall be12 913 UNC Threaded Rod, unless otherwise speci-fied (12 mm), and be embedded 4.5 6 0.1 inches (1156 2.5mm).

Baseline tests are defined as restrainedtests conducted on three12-inch (12 mm) anchors embedded4.5 6 0.1 inches (115 6 2.5 mm) in the same base materialusing the same installation method as the required environmen-tal test. If the environmental tests are conducted as unrestrainedtest, baseli
29、ne tests are not required.7.4.3 Test on Short-term Effect of FireThe purpose of thistest is to determine anchor performance when subjected to thetemperatures and times given in the fire-temperature curve inTest Method E 119. This test shall be conducted in theunrestrained mode. Install and test a mi
30、nimum of threeanchors. Use a test member that is sufficiently large (369 square(1 m square) to give realistic concrete or masonry response tothe fire temperature exposure in the vicinity of the test anchor.Condition the test member in accordance with Test MethodE119under the “Protection and Conditio
31、ning of Test Speci-men” section. A typical set-up is shown in Fig. 1. Duringtesting, subject the anchors to a constant tension load.This loadshall be the allowable load for the anchor as determined inSection 7.2, or other load as specified by the manufacturer.Maintain the load as the fire temperatur
32、e is increased inaccordance with the Test Method E119 time-temperaturecurve. Record temperature and displacement readings at1-minute increments until failure occurs.7.4.4 Radiation TestPerform these tests where the radia-tion resistance of the adhesive is required. The tests shall beconducted as res
33、trained tests, or unrestrained tests. If testing isconducted in the restrained mode, baseline tests are required.Install and test a minimum of three anchors. Expose the testspecimens to a minimum gamma radiation level of 2 3 107rads. Conduct tension tests and compare the irradiated anchorresults to
34、the baseline test results if the radiation tests wereconducted in the restrained mode. Compare the irradiatedanchor results to the results determined in Section 7.2 for thesame size anchor if the radiation tests were conducted in theunrestrained mode. Upon completion of the tests, the testingagency
35、shall be responsible for safely disposing of the testsamples in accordance with applicable regulations.7.4.5 Tests on Effect of Freezing and Thawing ConditionsThe tests shall be conducted as restrained tests, or unrestrainedtests. If testing is conducted in the restrained mode, baselinetests are req
36、uired. Install and test a minimum of three anchors.Freezing-and-thawing resistant concrete shall be used as anoption. Cover the surface of the test member, within aminimum 3-inch (76 mm) radius from the center of the testanchor, with tap water, maintaining a minimum of12-inch (12mm) depth throughout
37、 the test. Load each anchor with aconstant tension load equal to at least 40 % of the ultimate loadcapacity of the baseline tests for restrained tests, or 40 % of theultimate load capacity for the same size anchor determined inSection 7.2 for an unrestrained test. This load is to bemaintained during
38、 the freezing and thawing cycles. The nomi-nal freezing and thawing cycles shall consist of alternatelyE 1512 01 (2007)2lowering the temperature of the chamber to 10F (23C) andholding this temperature for 3 hours, then raising the tempera-ture to 104F (40C) and holding this temperature for 3 hours.M
39、easure the temperature at the surface of the concrete at alocation outside the standing water. At the completion of fiftycomplete cycles, conduct tension tests and compare the resultsto the baseline test results or to the results determined inSection 7.2 for the same size anchor as applicable.7.4.6
40、Tests on Effects of Damp EnvironmentThe tests shallbe conducted as restrained tests, or unrestrained tests. If testingis conducted in the restrained mode, baseline tests are required.Install and test a minimum of three anchors. Prior to anchorinstallations, fill the test holes with tap water and mai
41、ntain thewater level filled for a minimum of seven days. Immediatelyprior to installing the anchors, all freestanding water shall beremoved so that the walls of the test holes are surface moist.After the appropriate cure time has elapsed, conduct tensiontests to failure and compare the results to th
42、e baseline testresults or to the results determined in Section 7.2 for the samesize anchor as applicable. If the application requires installa-tion in water-filled holes, conduct the test as described aboveexcept that the freestanding water is not removed. Install theanchors in the water-filled hole

Install and test a minimum of three anchorsfor each temperature data point. Test a sufficient number oftemperature dat
44、a points to develop a load-temperature responsecurve of the adhesive anchor. Test, as a minimum 70F (21C)and at least four higher temperatures, one of which shall be atleast 180F (82C). All anchors are to be installed and cured at75F 6 10F (24C 6 5C). Following the recommended cureperiod, heat and m
45、aintain the specimens at the desired tem-perature for a minimum of 24 hours. Remove the test speci-mens from the heating chamber and tension test the anchorsimmediately in order to assure the test specimens remain at theconditioned temperature. A thermocouple inserted into the testmember may be used
46、 to confirm the temperature at the time oftesting. Plot a chart depicting the performance trend showingthe percentage change, compare to the strength at 70F (21C),attributed to the change in temperature.7.4.7.2 Tests on Effect of Reduced Temperature on CuringThe tests shall be conducted as restraine
47、d tests, or unrestrainedtests. Install and test a minimum of three anchors. Prior toinstallation, condition the anchor rod and test member to thedesired temperature and maintain that temperature for a mini-mum of 24 hours. Install the anchors and allow them to cure atthe stabilized temperature for t
48、he manufacturers recommendedcure time. Remove the test specimens from the coolingchamber and tension test the anchors immediately in order toassure the test specimens remain at the conditioned tempera-ture. A thermocouple inserted into the test member may beused to confirm the temperature at the tim
49、e of testing. Comparethe results to the load obtained in Section 7.4.7.1 at 70F(21C). When specific adhesives are recommended for usebelow 50F (10C), perform the following additional test:(a) Install and test a minimum of three anchors.
