22、the desired level with an accuracy of 61 %. Themass of the bag may be adjusted to any specified mass,depending upon the information desired.6.3 Measuring SticksA stick, laid off in 6-in.

Test Specimen8.1 SizeThe specimens shall be representative of theactual construction as to material, method of assembly, andworkmanship.8.2 Length or He

28、ightThe length or height of specimen foreach element shall be chosen to conform approximately to thelength or height of that element in actual size.8.3 WidthThe width of specimen shall be chosen, insofaras feasible, to include several of the principal load-carryingmembers to ensure that the behavior

29、 under load will simulatethat anticipated under service conditions. The actual width ofspecimens shall be a whole number multiplied by the spacingof the principal load-carrying members, except for prefabri-cated panels for which the actual width shall be the width ofpanel used. If the structural pro

30、perties of a particular construc-tion are to be compared with another construction, there shouldnot be a great difference in the actual widths of the specimens.8.4 AgeConstructions such as concrete and masonry(brick, structural clay tile, concrete block) for which thestructural properties depend upo

31、n the age of the specimen,shall be tested not less than 25 days nor more than 56 days afterfabrication except in special instances such as the case ofexisting panels. This age requirement applies also to plasteredand stuccoed constructions. Other assemblies affected bymoisture shall be conditioned t

32、o constant weight or moisturecontent, or for at least 2 weeks at 68 6 6F (20 6 3C) and 656 5 % relative humidity.8.5 NumberTests shall be made on a minimum of threelike specimens. However, more tests may be necessary depend-ing upon information and accuracy desired.FIG. 1 Impact Load Test (Specimen

33、Horizontal)E695 03 (2015)129. Procedure9.1 For symmetrical walls, apply the impact load to theoutside face from at least one of the specimens, and to theinside face of the other two specimens. For asymmetrical walls,test both sides an equal number of times. This will require aminimum of four test sp

34、ecimens. Exception: only one sideneed be tested at the option of the client and laboratorydepending upon information required. The report shall recordwhich side or sides of the specimen that is tested. For floor androof assemblies apply the impact loads only to the upperfinish-floor face of the spec

35、imen.NOTE 2Any criteria for pass/fail or for stopping the test should beagreed upon between the sponsor and testing agency prior to testing. Somepossible points include: the ability to sustain a specified static load afterthe impact drop; limitation on the instantaneous deflection or residual set;pe

36、netration of panel; destruction of panel (to be defined); or simply aspecified height of drop or number of drops per test from a specific height.9.2 Point of ImpactIf the construction has structuralmembers, that is, studs or joists, test each specimen so that atleast one such structural member will

37、be struck by the impactbag. Test each specimen also so that the impact bag will strikethe facing midway between two members.NOTE 3As written, this method may not necessarily define or test themost vulnerable part of a panel specimen.Additional tests may be requiredto locate such an area if this info

38、rmation is desired.9.3 Loading-Floor and Roof Assemblies-SpecimenHorizontalTest the specimen as a simple beam on a spannominally 6 in. (150 mm) less than the specimen length. Thetwo supports for the specimens shall prevent longitudinalrestraint and shall provide bearing for the entire width of thesp

39、ecimen. Secure the ends of the panel by hold-downs tominimize specimen bounce. Take care to assure that thehold-downs do not affect deflection of the specimen. Apply an(1) LeatherUse harness leather (oak tanned from packer hides) or latigo leather (alum and vegetable tanned) (see Terminology D1517,

40、E631 for definitions and terms)(1-oz leather =164 in. (0.4 mm) thick).(2) ThreadUse linen thread (minimum four-ply) in accordance with Fed. Spec. V-T-291E(1), Type B, Class 1 or 2. Double-stitch sidewall seam and seam attachingsidewall to the base.(3) ShotUse shot (0.039 to 0.138 in. (1 to 3.5 mm) d

41、iameter). Fill bag with shot and cover with two layers of 3 in. (76 mm) foam rubber.FIG. 2 Leather Drop Bag AssemblyE695 03 (2015)13impact load to the upper face of the specimen by dropping thebag beginning with a height of 6 614 in. (152 6 6 mm) andincreasing the height in 6 614-in. (152 6 6-mm) in

42、crements.Record set and instantaneous deflection measurements for eachdrop. For the first drop, measure the height of the bag from theupper face of the specimen at a point directly beneath the bag,and for subsequent drops, from a taut cord in contact with theupper face directly above the supports.9.

43、4 Loading-Wall Assemblies Specimen VerticalPositionthe specimen on cylindrical rollers to prevent transverserestraint. The axes of the rollers shall be parallel to the faces ofthe specimens. The two supporting rollers shall be in contactwith the vertical surface of the rigid frame and each roller sh

44、allrest horizontally on sponge rubber58 618 in. (16 6 3 mm)thick to prevent longitudinal restraint. Support the bag as apendulum in the frame as shown in Fig. 3. Take care to assurethat the hold-downs do not affect deflection of the specimen.Apply an impact load to the middle of the outer face of th

45、especimens by releasing the bag beginning with a height of 6 614 in. (152 6 6 mm) and increasing the height in 6 614-in.(152 6 6-mm) increments. The maximum useful height ofdrop will occur when the pendulum or frame is perpendicularto the specimen. Measure the height of drop from the point ofimpact

46、of the center of gravity of the bag as it strikes thespecimen to this same point when the bag is in the raisedposition. Release the bag by smoothly and swiftly opening thehinged doors, causing it to swing as a true pendulum thuseliminating wobbling.9.5 Instantaneous DeflectionUse the deflectometer (

47、see6.4) to measure the instantaneous deflection of the specimen.Prior to loading, hold the light metal rod in contact with themiddle of the lower face of the specimen by the clamp. Whenthe specimen deflects under the impact load, the rod is held inits lowest position by the friction clamp. Report re

48、adings to thenearest 0.01 in. (0.25 mm).9.6 SetTo measure the set, place the set gage on the upperface of the specimen. Take readings by placing the set gage onthe specimen with the legs at the supports and the spindle of thedial micrometer in contact with the middle of the specimen,and reading the

49、micrometer. If the set exceeds the range of themicrometer, place gage blocks between the specimen and thespindle of the micrometer to the nearest 0.001 in. (0.025 mm).10. Recordings10.1 Deflection and SetFor each height of drop calculatethe deflection between the reading of the deflectometer and theinitial reading. Similarly, calculate the set as the differencebetween the reading of the set gage and the initial reading.Record the maximum height of drop.11.
