SIGNIFICANCE AND USE
4.1 Much of the cushioned resilient flooring in use today is in household kitchens. Kitchen flooring is frequently subjected to the hazard of dropped tableware and cutting knives, that can puncture the wear layer of cushioned resilient flooring. Food and soil that become embedded in these punctures often can not be removed by ordinary maintenance, resulting in unsightly marks. Moisture, grease, or oils that penetrate to the cushion layer can be wicked into the foam and cause permanent discoloration. Ultimately, the service life of the material is shortened.
SCOPE
1.1 This test method covers the laboratory procedure for determining the resistance of cushioned resilient floor coverings to punctures from dropped pointed objects such as dinner forks.  
1.2 This test method employs a 35-g cylindrical dart with a flat, small-diameter tip that is dropped onto a specimen of flooring. The dart represents the weight of a typical fork and the tip produces a similar puncture to those which result from dropped forks.  
1.3 Flooring with thick wear layers may not puncture under even the most severe drop. Although data can be obtained by increasing the drop height or the weight of the dart, values of this magnitude have no practical application.  
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. For specific precaution statement see 8.2.

SIGNIFICANCE AND USE
3.1 The overall thickness or caliper of resilient flooring is a basic physical property. However, conventional means of measuring the thickness, such as a hand micrometer or regular dial micrometer, are not applicable for foam-layer products due to the error from compressing the foam. This test method minimizes this type of measuring error and still retains the convenience and speed of measurement.  
3.2 Measurement of the product thickness may be required for quality control purposes or to ensure compliance with applicable specifications.
SCOPE
1.1 This test method covers the determination of the thickness of resilient non-textile floor coverings containing a foam layer as part of the construction.

SIGNIFICANCE AND USE
4.1 This test method is designed to measure the vertical distance between any two levels on the face of the flooring, that is, between any two flat areas, between a flat area and any part of a textured area, or between two textured areas. This vertical distance may be of interest in itself or it may be applied to the questions of: (1) how much of the thickness of the flooring is available before the pattern is destroyed; or (2) how deep the depressed areas must be before valley printing ink is not walked on in normal traffic.
SCOPE
1.1 Two important characteristics involved in the manufacture of resilient flooring relate to the smoothness of the wear surface and the hardness of the layers under the wear surface. The surfaces may vary from completely textured areas to portions that are flat but separated by textured areas. This test method covers flooring with these interrupted wear surfaces which are not supported by soft, cushioned layers.  
1.2 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.

1.4 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.

SIGNIFICANCE AND USE
3.1 Installations of resilient floor tile require tight joints if satisfactory appearance is to result. The quality of cut of resilient tile is determined by this test method.
SCOPE
1.1 This test method covers a means of measuring and evaluating the quality of cut (joint tightness) of square or rectangular resilient floor tile. Characteristics that detract from a monolithic (seamless) appearance, such as burred, chipped, nicked, or beveled edges, or bow cut or rounded corners, are measured or observed, or both.  
1.2 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.  
1.3 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.

SIGNIFICANCE AND USE
4.1 Resilient floor covering is made by fusing polymer materials under heat or pressure, or both, in various manufacturing and decorating processes. The polymer material may be compounded with plasticizers, stabilizers, fillers, and other ingredients for processability and product performance characteristics. The formulation of the compound can be varied considerably depending on the desired performance characteristics and methods of processing.  
4.2 Light stability, which is resistance to discoloration from light, is a basic requirement for functional use.  
4.3 This test method provides a means of measuring the amount of color change in flooring products when subjected to accelerated light exposure over a period of time (functional use of the flooring product).  
4.4 This test method specifies that a sample is measured by a spectrophotometer and expressed in ΔE* units before and after accelerated light exposure.
Note 2: It is the intent that this test method be used for testing light stability performance properties to be referenced in resilient flooring specifications.
SCOPE
1.1 This test method covers a procedure for determining the resistance of resilient floor covering to color change from exposure to light over a specified period of time.  
1.2 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.  
1.3 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.

SIGNIFICANCE AND USE
4.1 Resilient flooring products are designed and formulated to have good resistance to most common chemicals encountered in typical use. High performance wear layers can also be used to enhance cleanability and chemical resistance. Resilient flooring used in residential and commercial environments may be subjected to a variety of chemicals through accidental spillage or as ingredients used for hygienic purposes. Performance is dependent upon the flooring formulation and that of the maintenance products used on the flooring. This test method provides a means of estimating the relative susceptibility of resilient floor covering to change when exposed to chemical reagents.
SCOPE
1.1 This test method provides a procedure for determining the resistance of resilient floor covering to surface deterioration when exposed to various chemical reagents. This test method is not intended as a staining test nor as a method to judge surface and appearance restoration of the sample after exposure to the chemical reagent.  
1.2 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.  
1.3 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. Specific hazard information is provided in Section 6 of this test method.  
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.

SIGNIFICANCE AND USE
4.1 The final appearance of an installed floor depends upon several factors. These include but are not limited to size and squareness in the case of tiles/planks, the quality of joint cut, the quality and preparation of the subfloor and the skill of the installer. Long term appearance of the installed floor is also dependent on but not limited to the ability of the tile/plank to resist shrinkage due to internal stress relief. This test method is used to measure the ability of the floor to retain its original dimensions following exposure to heat, simulating a long service life at reasonable and expected temperatures.
SCOPE
1.1 This test method covers the determination of the change in linear dimensions of resilient floor tile/plank products after exposure to heat and reconditioning to ambient temperature.  
1.2 This test method allows one to also measure curling that can occur after a specimen has been exposed to heat and reconditioned back to ambient temperature.  
1.3 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.  
1.4 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.

SIGNIFICANCE AND USE
4.1 When subjected to normal in-use traffic conditions, a flooring material is exposed to abrasion caused by the destructive action of fine hard particles. This situation occurs whenever loose debris, dirt and other particulate matter exists between traffic bodies (that is, shoes and a flooring surface). Under continuing exposure to an “abrasive action,” a flooring material may suffer a thickness loss sufficient to reduce its service life.  
4.2 Abrasion resistance measurements of resilient floor coverings can be complicated since the resistance to abrasion is affected by many factors. These may include the physical properties of the material in the floor covering surface, particularly its hardness and resilience; type and degree of added substances, such as fillers and pigments; surface characteristics of the specimen, such as type, depth, and amount of embossing. It can also be affected by conditions of the test, including the type and characteristics of the abradant and how it acts on the area of the specimen being abraded; pressure between the specimen and leather clad brass wheels; and vacuum suction.  
4.3 This test method is designed to simulate one kind of abrasive action and abradant that a flooring may encounter in the field. However, results should not be used as an absolute index of ultimate life because, as noted, there are too many factors and interactions to consider. Also involved are the many different types of service locations. Therefore, the data from this test method are of value chiefly in the development of materials and should not be used without qualifications as a basis for commercial comparisons.
SCOPE
1.1 This test method2 describes a laboratory procedure for determining the abrasion resistance of resilient flooring using an abrader with a grit feeder.3  
1.2 The equipment used in this test method is a modification of the Taber abraser. The regular abrading wheels are replaced by leather clad brass wheels (rollers). As the specimen holder rotates, a grit-feeding device dispenses aluminum oxide grit onto the specimen before the grit passes under the leather clad brass wheels. As the specimen rotates, the rub-wear action of the wheels and abrasive grit causes abrasion on the test piece. Using the vacuum system incorporated in the apparatus, the used grit and abraded material are removed after passing under both wheels.  
1.3 This test method employs a rotary, rubbing action caused by loose abrasive grit and the two abrading wheels. One wheel rubs the specimen from the center outward and the other from the outside toward the center. The wheels traverse a complete circle and have an abrasive action on the rotating specimen at all angles. This action approaches the twisting action between shoe and floor that occurs when a person turns. The use of loose grit serves the function of an abradant and also aids in the rolling action characteristic of normal walking.  
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. 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.  
1.5 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.  
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.

SIGNIFICANCE AND USE
4.1 Resilient floor tile is subjected to impacts from objects that may be inadvertently dropped on to surfaces. It is not possible to know all of the factors related to the dropped objects (shape, weight, height of drop) or the condition of the environment in which the tile is located (types of subfloor, degree of adhesion to subfloor, temperature). Therefore, this test method can only provide a relative measure of resistance of resilient floor tile to impact.
SCOPE
1.1 This test method measures the resistance to impact of resilient floor tile.  
1.2 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.

4.4 This test method specifies that a sample is measured by a spectrophotometer and expressed in ΔE* units before and after accelerated light exposure.
Note 2: It is the intent that this test method be used for testing light stability performance properties to be referenced in resilient flooring specifications.
SCOPE
1.1 This test method covers a procedure for determining the resistance of resilient floor covering to color change from exposure to light over a specified period of time.  
1.2 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.

SIGNIFICANCE AND USE
4.1 Much of the cushioned resilient flooring in use today is in household kitchens. Kitchen flooring is frequently subjected to the hazard of dropped tableware and cutting knives, that can puncture the wear layer of cushioned resilient flooring. Food and soil that become embedded in these punctures often can not be removed by ordinary maintenance, resulting in unsightly marks. Moisture, grease, or oils that penetrate to the cushion layer can be wicked into the foam and cause permanent discoloration. Ultimately, the service life of the material is shortened.
SCOPE
1.1 This test method covers the laboratory procedure for determining the resistance of cushioned resilient floor coverings to punctures from dropped pointed objects such as dinner forks.  
1.2 This test method employs a 35-g cylindrical dart with a flat, small-diameter tip that is dropped onto a specimen of flooring. The dart represents the weight of a typical fork and the tip produces a similar puncture to those which result from dropped forks.  
1.3 Flooring with thick wear layers may not puncture under even the most severe drop. Although data can be obtained by increasing the drop height or the weight of the dart, values of this magnitude have no practical application.  
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 whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability and regulatory limitations prior to use. For specific precaution statement see 8.2.

SIGNIFICANCE AND USE
4.1 When subjected to normal in-use traffic conditions, a flooring material is exposed to abrasion caused by the destructive action of fine hard particles. This situation occurs whenever loose debris, dirt and other particulate matter exists between traffic bodies (that is, shoes and a flooring surface). Under continuing exposure to an “abrasive action,” a flooring material may suffer a thickness loss sufficient to reduce its service life.  
4.2 Abrasion resistance measurements of resilient floor coverings can be complicated since the resistance to abrasion is affected by many factors. These may include the physical properties of the material in the floor covering surface, particularly its hardness and resilience; type and degree of added substances, such as fillers and pigments; surface characteristics of the specimen, such as type, depth, and amount of embossing. It can also be affected by conditions of the test, including the type and characteristics of the abradant and how it acts on the area of the specimen being abraded; pressure between the specimen and leather clad brass wheels; and vacuum suction.  
4.3 This test method is designed to simulate one kind of abrasive action and abradant that a flooring may encounter in the field. However, results should not be used as an absolute index of ultimate life because, as noted, there are too many factors and interactions to consider. Also involved are the many different types of service locations. Therefore, the data from this test method are of value chiefly in the development of materials and should not be used without qualifications as a basis for commercial comparisons.
SCOPE
1.1 This test method2 describes a laboratory procedure for determining the abrasion resistance of resilient flooring using an abrader with a grit feeder.3  
1.2 The equipment used in this test method is a modification of the Taber abraser. The regular abrading wheels are replaced by leather clad brass wheels (rollers). As the specimen holder rotates, a grit-feeding device feeds aluminum oxide grit onto the specimen before it passes under the leather clad brass wheels. Using the vacuum system incorporated in the apparatus, the used grit and abraded material are removed after passing under both wheels.  
1.3 This test method employs a rotary, rubbing action caused by loose abrasive grit and the two abrading wheels. One wheel rubs the specimen from the center outward and the other from the outside toward the center. The wheels traverse a complete circle and have an abrasive action on the rotating specimen at all angles. This action approaches the twisting action between shoe and floor that occurs when a person turns. The use of loose grit serves the function of an abradant and also aids in the rolling action characteristic of normal walking.  
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.

SIGNIFICANCE AND USE
4.1 Flexibility is that property of a material which allows it to be deformed by bending or rolling without cracking, breaking, or other permanent defects, using whatever force is necessary to bend or roll it. Flexibility is an important characteristic of flooring in that it provides for ease of handling in rolling, cutting, and fitting.

SIGNIFICANCE AND USE
4.1 Conductive and static dissipative floors (static control flooring) serve as a convenient means of electrically connecting persons and objects together to prevent the accumulation of electrostatic charges. A static control floor is specified on the basis of controlled resistance values. The surface of the floor provides a path of moderate electrical conductivity between all persons and equipment making contact with the floor to prevent the accumulation of dangerous electrostatic charges. Static control footwear will need to be used in conjunction with the floor for the floor to perform effectively with personnel.  
4.2 The resistance of some flooring materials change with age. Floors of such materials should have an initial resistance low enough or high enough to permit increase or decrease in resistance with age without exceeding the limits prescribed in the product specifications.
SCOPE

It is not possible to know all of the factors related to the dropped objects (shape, weight, height of drop) or the condition of the environment in which the tile is located (types of subfloor, degree of adhesion to subfloor, temperature). Therefore, this test method can only provide a relative measure of resistance of resilient floor tile to impact.

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.

SIGNIFICANCE AND USE
Both dimension and squareness of resilient floor tile are important considerations, because installed flooring may exhibit an objectionable appearance when either or both characteristics deviate from established tolerances. This test method provides a means of determining actual dimensions and squareness by using a single apparatus and procedure.

SIGNIFICANCE AND USE
Flexibility is that property of a material which allows it to be deformed by bending or rolling without cracking, breaking, or other permanent defects, using whatever force is necessary to bend or roll it. Flexibility is an important characteristic of flooring in that it provides for ease of handling in rolling, cutting, and fitting.
SCOPE
1.1 This test method covers the determination of the flexibility of resilient flooring materials by means of cylindrical mandrel apparatus. It is especially applicable to sheet goods and some tiles.
