Standard Test Method for Determining FF Floor Flatness and FL Floor Levelness Numbers

Standard Test Method for Determining <span class="bdit">F<sub>F</sub></span><span class="bold"> Floor Flatness and </span><span class="bdit">F<sub>L</sub></span><span class="bold"> Floor Levelness Numbers </span>

SIGNIFICANCE AND USE
This test method provides statistical (and graphical) information concerning floor surface profiles.
Results of this test method are used primarily to:
Establish compliance of randomly trafficked floor surfaces with specified FF Flatness and FL Levelness tolerances,
Evaluate the effect of different construction methods on resulting floor surface flatness and levelness, and
Investigate the curling and deflection of floor surfaces.
Results of this test method shall not be used to enforce contract flatness and levelness tolerances on those floor installations primarily intended to support the operation of fixed-path vehicle systems (for example, narrow aisle warehouse floors).
Note 2—When the traffic patterns across a floor are random, (as is generally the case) evaluation of the floor's FF Flatness and FL Levelness will necessarily involve a random sampling of the surface, since all of the infinite potential profiles to be seen by the traffic can not possibly be measured. In those instances when the traffic across a floor will be confined to specific paths, however, the requirement for random sampling is eliminated, since the floor can indeed be inspected exactly as it will be seen by all of the traffic. In these special cases, rather than inferring the condition of the traffic paths from a random sample, it is far more useful to measure each of the traffic paths directly using continuous recording floor profilometer configured to run exactly in the traffic wheel paths. Such direct simulation measurements eliminate the inherent uncertainties of statistical sampling and provide profile information immediately applicable to the correction of the surface in way of the future traffic.
SCOPE
1.1 This test method covers a quantitative method of measuring floor surface profiles to obtain estimates of the floor's characteristic FF  Flatness and FL Levelness Face Floor Profile Numbers (F-Numbers) using the inch-pound system of units.
Note 1—A complete metric companion to Test Method E 1155 has been developed, Test Method E 1155M; therefore, no metric equivalents are shown in this test method.  
1.2 The text of this test method references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this test method.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Standard Test Method for Determining Floor Tolerances Using Waviness, Wheel Path and Levelness Criteria

SIGNIFICANCE AND USE
5.1 This test method provides statistical and graphical information concerning floor surface profiles.  
5.2 Results of this test method are for the purpose of:  
5.2.1 Establishing compliance of random or fixed-path trafficked floor surfaces with specified tolerances,  
5.2.2 Evaluating the effect of different construction methods on the waviness of the resulting floor surface,  
5.2.3 Investigating the curling and deflection of concrete floor surfaces,  
5.2.4 Establishing, evaluating, and investigating the profile characteristics of other surfaces, and  
5.2.5 Establishing, evaluating, and investigating the levelness characteristics of surfaces.  
5.3 Application:  
5.3.1 Random Traffic—When the traffic patterns across a floor are not fixed, two sets of survey lines, approximately equally spaced and at right angles to each other, shall be used. The survey lines shall be spaced across the test section to produce lines of approximately equal total length, both parallel to and perpendicular to the longest test section boundary. Limits are specified in 7.2.2 and 7.3.2.  
5.3.2 Defined Wheel Path Traffic—For surfaces primarily intended for defined wheel path traffic, only two wheel paths and the initial transverse elevation difference (“side-to-side”) between wheels shall be surveyed.  
5.3.3 Time of Measurement—For new concrete floor construction, the elevation measurements shall be made within 72 h of final concrete finishing. For existing structures, measurements shall be taken as appropriate.  
5.3.4 Elevation Conformance—Use is restricted to shored, suspended surfaces.  
5.3.5 RMS Levelness—Use is unrestricted, except that it is excluded from use with cambered surfaces and unshored, elevated surfaces.
SCOPE
1.1 This test method covers data collection and analysis procedures to determine surface flatness and levelness by calculating waviness indices for survey lines and surfaces, elevation differences of defined wheel paths, and levelness indices using the inch-pound system of units.
Note 1: This test method is the companion to SI Test Method E1486M; therefore, no SI equivalents are shown in this test method.
Note 2: This test method was not developed for, and does not apply to, clay or concrete paver units.  
1.1.1 The purpose of this test method is to provide the user with floor tolerance estimates as follows:
1.1.1.1 Local survey line waviness and overall surface waviness indices for floors based on deviations from the midpoints of imaginary chords as they are moved along a floor elevation profile survey line. End points of the chords are always in contact with the surface. The imaginary chords cut through any points in the concrete surface higher than the chords.
1.1.1.2 Defined wheel path criteria based on transverse and longitudinal elevation differences, change in elevation difference, and root mean square (RMS) elevation difference.
1.1.1.3 Levelness criteria for surfaces characterized by either of the following methods: the conformance of elevation data to the test section elevation data mean or the conformance of the RMS slope of each survey line to a specified slope for each survey line.  
1.1.2 The averages used throughout these calculations are RMS (that is, the quadratic means). This test method gives equal importance to humps and dips, measured up (+) and down (−), respectively, from the imaginary chords.  
1.1.3 Appendix X1 is a commentary on this test method. Appendix X2 provides a computer program for waviness index calculations based on this test method.  
1.2 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicab...

ASTM E3118/E3118M-22(Test Method)
Standard Test Methods to Evaluate Seismic Performance of Suspended Ceiling Systems by Full-Scale Dynamic Testing

SIGNIFICANCE AND USE
5.1 The test protocol evaluates those complex suspended ceiling systems that cannot be assessed by simple engineering calculations contained in ASCE/SEI 7 and Practice E580/E580M. It is not intended to replace the requirements in ASCE/SEI 7. Suspended ceiling systems are considered nonstructural components of buildings.
SCOPE
1.1 These test methods help evaluate the performance of a full-scale suspended ceiling system during a seismic event using a dynamic seismic simulator (shake table).  
1.2 These full-scale procedures are not the only available procedures for evaluating the seismic performance of ceiling systems. These tests do not preclude the use of other small-scale or full-scale component or system testing.  
1.3 These test methods contain two independent procedures.  
1.3.1 Comparative method where the level of performance of an experimental system is compared to that of a control test system under the same set of conditions.  
1.3.2 Non-comparative method where a single test is conducted to establish the level of performance of an experimental system.  
1.4 These test procedures are valid and useful for all types of suspended ceiling systems.  
1.5 The text of this standard uses notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.  
1.6 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

1.5 No consideration is given in these test methods to any possible deterioration of metal railing systems, rails, and connections, resulting from adverse environmental conditions. The performance of special tests covering this aspect may be desirable.  
1.6 These test methods are limited to the application of the loads described herein.  
1.7 Should computations make it possible to provide the needed information, testing can be employed for verification.  
1.8 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.9 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see 11.2.

Standard Test Method for Determining FF Floor Flatness and FL Floor Levelness Numbers

SIGNIFICANCE AND USE
5.1 This test method provides statistical (and graphical) information concerning floor surface profiles.  
5.2 Results of this test method are used primarily to:  
5.2.1 Establish compliance of randomly trafficked floor surfaces with specified FF Flatness and FL Levelness tolerances,  
5.2.2 Evaluate the effect of different construction methods on resulting floor surface flatness and levelness, and  
5.2.3 Investigate the curling and deflection of floor surfaces.  
5.3 Results of this test method shall not be used to enforce contract flatness and levelness tolerances on those floor installations primarily intended to support the operation of fixed-path vehicle systems (for example, narrow aisle warehouse floors).
Note 2: When the traffic patterns across a floor are random, (as is generally the case) evaluation of the floor's FF Flatness and FL Levelness will necessarily involve a random sampling of the surface, since all of the infinite potential profiles to be seen by the traffic can not possibly be measured. In those instances when the traffic across a floor will be confined to specific paths, however, the requirement for random sampling is eliminated, since the floor can indeed be inspected exactly as it will be seen by all of the traffic. In these special cases, rather than inferring the condition of the traffic paths from a random sample, it is far more useful to measure each of the traffic paths directly using continuous recording floor profilometer configured to run exactly in the traffic wheel paths. Such direct simulation measurements eliminate the inherent uncertainties of statistical sampling and provide profile information immediately applicable to the correction of the surface in way of the future traffic.
SCOPE
1.1 This test method covers a quantitative method of measuring floor surface profiles to obtain estimates of the floor's characteristic FF Flatness and FL Levelness Face Floor Profile Numbers (F-Numbers) using the inch-pound system of units.
Note 1: A complete metric companion to Test Method E1155 has been developed, Test Method E1155M; therefore, no metric equivalents are shown in this test method.  
1.2 The text of this test method references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this test method.  
1.3 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Practice for Gravity Load Testing of Floors and Low Slope Roofs

SIGNIFICANCE AND USE
4.1 This practice is intended to be used by parties involved in the testing of floors and roofs of structures either in the field or the laboratory. Tests are either proof tests or tests to failure, and are applicable to all construction materials. The practice is not intended for use in routine quality control testing of individual building elements or constructions.
SCOPE
1.1 This practice covers static load testing of floors and low slope roofs (roofs having a slope of less than 1 in 12) under actual or simulated service conditions, and is applicable to typical elements or sections of structures fabricated for test or to actual existing building components. This practice is intended for use in determining the strength and stiffness of elements or sections of floors and roofs of buildings under gravity loads, as well as in checking the design, materials, connections, and the quality of the fabrication of such building constructions.  
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM F3441-23a(Guide)
Standard Guide for Measurement of pH Below Resilient Flooring Installations

SIGNIFICANCE AND USE
4.1 There is typically a higher concentration of soluble alkali salts in the surface region of a concrete slab due to the initial bleeding process of a freshly placed concrete slab. If after a resilient floor covering material is installed there is sufficient moisture within the slab to place these salts into solution a potentially damaging high pH solution can develop beneath the installed material.  
4.2 Results obtained through the use of this guide indicate the comparative pH of reagent water placed on properly prepared concrete slab surfaces only at the time of the procedure and in the specific locations evaluated.  
4.3 If pre-installation surface pH evaluation is required by the manufacturer of the resilient flooring, adhesive, patching/underlayment products or project specifications, their instructions and limitations should be consulted.
SCOPE
1.1 This guide discusses procedures that may be used for evaluating the comparative change in pH of reagent water placed on the surface of a properly prepared concrete slab surface.  
1.2 This guide is intended to be used in conjunction with the flat surface electrode pH meter manufacturer’s calibration procedures, operation instructions, and interpretive data where available.  
1.3 This guide is intended to be used in conjunction with the pH paper manufacturer’s instructions, product shelf life, and interpretive data where available.  
1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use Some specific hazards statements are given in Section 9 on Hazards.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
