3.1 Definitions—Refer to Terminology E631 for definitions of terms used in these test methods.
4. Significance and Use
4.1 Transverse Load—The procedures outlined will serve to evaluate the performance of floor and roof segments for deflection,
permanent set and ultimate capacity. Performance criteria based on data from these procedures can ensure structural adequacy and
effective service.

5. Test Specimens
5.1 Specimens—There shall be at least three replicate specimens for each test. Specimens shall be constructed to represent
sections of the floor, or roof assembly including the means of the attachment when the load direction is away from the supports.
The specimens shall be representative in width and length as to the material and workmanship. The test specimen shall not be less
than the width and length of the tributary load area under actual conditions. If the tributary load area for the test specimen exceeds
the test equipment, a reduced specimen that is representative in proportional width and length shall be tested. Unsymmetrical
assemblies shall be tested in each axis. If the structural properties of a particular construction are to be compared with another
construction, widths of the specimens shall be of comparable size.
5.2 Age—Constructions, which include concrete and masonry for which the structural properties depend upon the age of the
specimen, shall be aged not less than what is indicated by the manufacturer or national standard, or both. The age of the specimen
shall be recorded in the report.
6. Loading
6.1 Apparatus—The testing machine or load-measuring apparatus shall comply with the requirements prescribed in Practices
E4.
6.2 Application of Load—Apply the load to each individual specimen in increments so that a sufficient number of readings will
be obtained to determine definitely the load-deformation curve (see 6.3) using the following sequence:
6.2.1 Prior to testing, apply a small initial load not greater than 5 % of the ultimate capacity load expected and hold for 5 min
(6 1 (61 min) and then release. Zero all measuring devices and begin the test.
6.2.2 Record the initial load and deformation reading of the specimen and then increase the load on the specimen to the first
predetermined increment.
6.2.3 Record the load and deformation reading and release the load back to the initial load and then record the set of the
specimen.
6.2.4 Increase the load to the next predetermined increment and record the information as indicated in the first load increment
above. Follow this sequence of loading and reading for all predetermined load increment(s).
6.3 Duration of Load Application—After each increment of load is applied, maintain the load level as constant as possible for
a period of 5 min (see Note 1). Take deformation readings as soon as practical after load application, at the end of the 5-min period
under constant load, and immediately and at the end of the 5-min period after any partial or complete load release. Plot initial and
5-min readings in the form of load-deformation curves. Maintain complete load-deformation time records throughout the test. If
application of a given load is required for a certain period, such as 24 h, take deformation readings at the end of this period, to
allow the satisfactory plotting of a time-deformation curve for the complete period.
NOTE 1—Reason for the 5-min application of constant-level increment loads are as follows:
(1) To permit the assembly to come to a substantial rest prior to taking the second set of readings. (Depending on the method employed for applying
the test load, it may be necessary to continue, at a reduced rate, the motion of the loading device in order to maintain the constant load level during the
5-min period.)
(2) To observe any time-dependent deformation or load redistribution, or both, and to record accurately the load level when time-dependent
deformation starts, that is, at the divergence of the immediate and delayed load-deformation curves. This load level may, under certain conditions, have
an important bearing on the design load.
(3) To be able to stop the test, if this should be desirable, prior to total failure, after initial failure has been anticipated as a result of the observations.
(4) To assure uniformity in test performance and consistency in test results.
E2322 − 03 (2015)
7. Deformation Measurements
7.1 Measure the deformations with sufficient precision to define the load-deformation relationship, and report at least to the
nearest 0.25 mm.
8. Report
8.1 Prepare the report in accordance with Recommended Practice E575.
9. Precision and Bias
9.1 It is not possible to specify the precision of the procedure in this standard for measuring these test methods because of the
variety of materials and combinations of materials involved.
TESTING FLOORS
10. Transverse Load—Floor
10.1 Test Specimen(s)—Test specimen(s) shall be constructed in accordance with Section 5.
10.2 Apparatus—The apparatus shall be capable of applying a uniform load (such as air bag load or vacuum load), gravity load
or two point load and shall conform to the requirements prescribed in 10.2.1 through 10.2.3 or the equivalent.
10.2.1 Uniform Load—Uniformly distributed loading is a satisfactory test method. Uniformly distributed load shall be applied
by air pressure, either in a bag or in a vacuum chamber.
10.2.1.1 The bag method of loading is schematically shown in Fig. 1. Connect a reaction platform parallel to the face to be
loaded and wider than the specimen to the supports by tie rods. Place an airtight bag as wide as the specimen and as long as the
span between the specimen and the reaction platform. Apply transverse load to the specimen by increasing the air pressure in the
bag. Measure the difference in pressure by means of a manometer or other pressure measuring device. The error of the pressure
reading shall not exceed 1 % of the full-scale reading. Deflection measurement shall be measured following 10.4. See Fig. 1.
10.2.1.2 When the vacuum chamber method of loading is used, place the specimen near the test frame to create an airtight
vacuum chamber. An airtight frame or curb shall surround the specimen closely and be flush with the upper surface of the
specimen. An air resistant blanket covers the specimen, overlaps the frame, and is sealed so that it is reasonably airtight. Use a
vacuum pump or positive action exhaust blower to reduce air pressure between the specimen and floor/wall. Measure the difference
in pressure by means of a manometer or other pressure measuring device. The error of the pressure reading shall not exceed 1 %
of the full scale reading. Deflection measurement shall be conducted following 10.4. See Fig. 2.
10.2.2 Gravity Load—Gravity load testing shall be conducted in accordance with Practice E196.
10.2.3 Two Point Load—The two point (quarter-point) loading method is used for transverse load tests. Test the specimen as
a simple beam (Fig. 3) on a span 150 mm less than the specimen length. Apply two equal loads, each at a distance of one-quarter
of the span from the supports, toward the middle of the span. For floor specimens tested horizontally (Fig. 1), the load on the
specimen shall include the weight of the specimen between the supports. Apply the transverse loads to the upper (finish floor) face

for three of the symmetrical specimens. For asymmetrical assemblies, the bottom face for three of the specimens must also be
tested. Deflection measurements shall be measured following 10.4. See Fig. 3.
10.3 Loading Application—The application of load is found in 6.2. The application of load shall be compatible with the test
apparatus indicated in 10.2.
10.4 Deflection Measurement Device—The deflection measurement device shall be compatible with the test apparatus indicated
in 10.2. A frame shall be placed on the upper face of the specimen in a manner such that the frame shall not deform as the specimen
deforms under load. Two deflection measuring devices, one near each longitudinal edge of the specimen, shall be attached to the
frame at the mid span.
10.4.1 Method A—Deflection Measuring Device Top of Panel—Mid span deflection shall be measured on the top of the panel.
The deflection measurement should be referenced to the panel deflection at the end supports.
10.4.2 Method B—Deflection Measuring Device Bottom of Panel—Mid span deflection shall be measured on the bottom of the
panel. The deflection measurement should be referenced to the panel deflection at the end supports.
10.5 Calculations and Report:
10.5.1 Load-Deflection Data—For each deflection measuring device, calculate the deflection under a given load as the
difference between the reading when the load is applied and the initial reading. Calculate the deflection of the specimen for the
span as the average of the deflections obtained from each of the measuring devices. Calculate the sets under the initial load by using
a similar method. Record the maximum load for each specimen.
10.5.2 Data Presentation—Report the results in the form of a graph in accordance with Section 8.

11.2 Apparatus—The apparatus shall be assembled as shown in Fig. 4 and shall conform to the requirements for component
parts prescribed in 11.2.1 through 11.2.3 or the equivalent.
11.2.1 Steel Bar—Steel bar having a diameter of 25.4 mm and the edge of the face contacting the specimen rounded to a radius
of 1.3 mm. When testing for decking deflection, place a 25.4 mm diameter flat disk between the steel load bar and the decking
surface.
