Standard Test Method for Measurement of Retroreflective Signs Using a Portable Retroreflectometer at a 0.2 Degree Observation Angle

SIGNIFICANCE AND USE
5.1 Measurements made by this test method are related to the night time brightness of retroreflective traffic signs approximately facing the driver of a mid-sized automobile equipped with tungsten filament headlights at about 200 m distance.  
5.2 Retroreflective material used on traffic signs degrades with time and requires periodic measurement to ensure that the performance of the retroflection provides adequate safety to the driver.  
5.3 The quality of the sign as to material used, age, and wear pattern will have an effect on the coefficient of retroreflection. These conditions need to be observed and noted by the user.  
5.4 This test method is not intended for use for the measurement of signs when the instrument entrance and observation angles differ from those specified herein.
SCOPE
1.1 This test method covers measurement of the retroreflective properties of sign materials such as traffic signs and symbols (vertical surfaces) using a portable retroreflectometer that can be used in the field. The portable retroreflectometer is a hand-held instrument with a defined standard geometry that can be placed in contact with sign material to measure the retroreflection in a standard geometry. The measurements can be compared to minimum requirements to determine the need for replacement. Entrance and observation angles specified in this test method are those used currently in the United States and may differ from the angles used elsewhere in the world.  
1.2 This test method is intended to be used for the field measurement of traffic signs but may be used to measure the performance of materials before placing the sign in the field or before placing the sign material on the sign face.  
1.3 This test method covers measurements at a 0.2 degree observation angle. See Test Method E2540 for measurements at a 0.5 degree observation angle.  
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 Measuring Colorimetric Characteristics of Retroreflectors Under Nighttime Conditions

SIGNIFICANCE AND USE
5.1 This practice describes a procedure for measuring the chromaticity of retroreflectors in a nighttime, that is, retroreflective, geometry of illumination and observation. CIE Standard Source A has been chosen to represent a tungsten automobile headlamp. Although the geometry must be specified by the user of this practice, it will, in general, correspond to the relationship between the vehicle headlamp, the retroreflector, and the vehicle driver's eyes. Thus, the chromaticity coordinates determined by the procedures in this practice describe numerically the nighttime appearance of the retroreflector.
SCOPE
1.1 This practice describes the instrumental determination of retroreflected chromaticity coordinates of retroreflectors. It includes the techniques used in a photometric range to measure retroreflected (nighttime) chromaticity with either a telecolorimeter or telespectroradiometer.  
1.2 This practice covers the general measurement procedures. Additional requirements for specific tests and specifications are described in Section 7.  
1.3 The description of the geometry used in the nighttime colorimetry of retroreflectors is described in Practice E808 and the methods for calculation of chromaticity are contained in Practice E308.  
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.

ASTM E2367-05(2019)(Test Method)
Standard Test Method for Measurement of Nighttime Chromaticity of Pavement Marking Materials Using a Portable Retroreflection Colorimeter

SIGNIFICANCE AND USE
5.1 The chromaticity of the stripe is determined by means of the tristimulus values X, Y and Z for the CIE 1931 (2°) standard observer for CIE standard illuminant A, which are converted to the chromaticity coordinates (x, y) and shown in the CIE 1931 (x, y)-chromaticity diagram. Refer to Practice E308.  
5.2 Under the same conditions of illumination and viewing, the chromaticity coordinates (x, y) represent the nighttime color of pavement markings in vehicle headlamp illumination as seen by drivers of the vehicles.  
5.3 The chromaticity of pavement (road) markings may change with traffic wear and require periodic measurement to ensure that the chromaticity is maintained within boundaries (see Specification D6628 for examples of color boundaries).  
5.4 As specified by CEN EN 1436 and Test Method E1710, the measurement geometry of the instrument is based on a viewing distance of 30 m, a headlamp mounting height of 0.65 m and an eye height of 1.2 m.  
5.5 It shall be the responsibility of the user to employ an instrument having the specified observation and entrance angles.
SCOPE
1.1 This test method covers measurement of the nighttime chromaticity coordinates (x, y) of horizontal pavement markings, such as traffic stripes and surface symbols, using a portable retroreflection colorimeter that can be placed on the road delineation to measure the chromaticity at a prescribed geometry.  
1.2 The entrance and observation angles of the retrorecolorimeter affect the readings. As specified by the European Committee for Standardization (CEN EN 1436), the entrance and observation angles shall be 88.76° and 1.05°, respectively.  
1.3 This test method is intended to be used for field measurement of pavement markings but may be used to measure the chromaticity of materials on sample panels before placing the marking material in the field.  
1.4 The portable retroreflection colorimeter may integrate measurement of the coefficient of retroreflected luminance RL in accordance with Test Method E1710 and thus be an integrated retroreflectometer/ retroreflection colorimeter.  
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.

ASTM E3165-18(Test Method)
Standard Test Method for Nighttime Retroreflected Chromaticity of Retroreflective Sheeting

SIGNIFICANCE AND USE
5.1 The results of this test method are used to assess conformance of retroreflective sheeting to the nighttime color requirements of industry standards and government regulations, such as Specification D4956 and U.S. Code of Federal Regulations Title 23 Part 655 Subpart F.  
5.2 Requirements in specifications referring to this test method are for the chromaticity of the material as viewed at night. These requirements are generally stated using four or five corner points that form a box that limits the range of acceptable chromaticity. Most of these specifications are categorical in nature; they describe a small range of colors that are recognizable from a color naming or coding purpose  
5.3 The method for compliance with the specification is to plot the measured (x, y) values and determine if the measured point falls within the specification box for the color of interest.
SCOPE
1.1 This test method describes the instrumental determination of the nighttime retroreflected chromaticity coordinates of retroreflective sheeting.  
1.2 This method includes a procedure based on tristimulus filter colorimetery and a procedure based on spectral measurements.  
1.3 A single set of test geometries (using 0.33° observation angle and 5° entrance angle) and apertures are described in this method.  
1.4 The resulting chromaticity coordinates are for use with the CIE 1931 chromaticity system utilizing CIE Illuminant A.  
1.5 If measurements and calculations are required for other sources of illumination, or geometries, or other materials, the user is referred to the general practice described in Practice E811.  
1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
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.

Standard Test Method for Crash Testing of Vehicle Security Barriers

SIGNIFICANCE AND USE
5.1 This test method provides a structured procedure to establish a penetration rating for vehicle perimeter barriers subjected to a vehicle impact. Knowing the penetration rating helps to select an appropriate barrier for site-specific conditions around a facility.  
5.2 The barrier penetration rating does not imply that a barrier will perform as rated in all site conditions, approach routes, and topography. Also, only single-specimen tests at a specified impact location are required by this test method, and therefore, not all points of impact can be tested and validated for the penetration rating. Other impact locations may respond differently.
SCOPE
1.1 This test method provides a range of vehicle impact conditions, designations, and penetration performance levels. This will allow an agency to select passive perimeter barriers and active entry point barriers appropriate for use at facilities with a defined moving vehicle threat. Agencies may adopt and specify those condition designations and performance levels in this test method that satisfy their specific needs. Agencies may also assign certification ratings for active and passive perimeter barriers based on the tests and test methodologies described herein. Many test parameters are standardized to arrive at a common vehicle type and mass, and replication, and produce uniform rating designations.  
1.2 Compliance with these test procedures establishes a measure of performance but does not render any vehicle perimeter barrier invulnerable to vehicle penetration. Caution should be exercised in interpreting test findings and in extrapolating results to other than test conditions and to user site conditions. This standard does not confirm the performance of the test barrier in the user site conditions. While computer simulations are powerful tools that are useful in the development of new and improved barriers or in estimating performance under differing conditions, the analytical models and methods must be validated against physical test data. When performing a test, developers and users are encouraged to address specific or unusual user site conditions as needed.  
1.2.1 Often local terrain features, soil conditions, climate, or other items will dictate special needs at specific locations. Therefore, if user site conditions are likely to degrade a barrier’s performance, the agency in need of a vehicle perimeter barrier should require testing with the specific user site conditions replicated for full-scale crash testing or numerical simulations that explicitly represent the user site conditions and have demonstrated connection to the “as-tested” soil configuration. For example, if the user site conditions are expansive clays, one could obtain user site materials and provide those to the test lab for the full-scale crash test.  
1.3 Product/design certification under this test method only addresses the ability of the barrier to withstand the impact of the test vehicle. It does not represent an endorsement of the product/design or address its operational suitability.  
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.  
1.5 This test method is intended to replace all previous versions of the test method for current and future testing.  
1.6 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 to determine the applicability of regulatory limitations prior to use.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established ...

ASTM D711-23(Test Method)
Standard Test Method for No-Pick-Up Time of Pavement Markings

SIGNIFICANCE AND USE
3.1 This test method serves as a laboratory control test. Types of pavement markings that can be tested with this method are waterborne traffic paint, solvent borne traffic paint, and some two component 100 % solids liquid pavement markings, such as epoxy and modified epoxy pavement markings. If wet film thickness, temperature, and humidity are controlled within the tolerances specified herein, this method can be useful for relative testing of pavement markings and potentially for qualification of pavement markings for field application in approved specifications. For improved repeatability and meaningful comparison of pavement markings samples being tested, consistent air flow over the pavement marking films during testing is important. The buyer and seller should agree upon the air flow conditions, whether it be static or carefully regulated air flow (see 4.6.1 and 4.6.2). Because of the many variables operative in the field application of pavement markings (for example, wet film thickness, air temperature, humidity, wind speed, pavement type (asphalt or concrete), film profile over pavement, pavement temperature, pavement porosity, pavement moisture content, and the presence or absence of direct sunlight during striping), a direct correlation between the results of this test and field applications is difficult to obtain. However, relative field performance can be predicted using this method if the testing protocol is adhered to. For testing of two component 100 % solids liquid pavement markings an application of drop on retroreflective optics are typically applied at a specified rate to the markings prior to testing. For these types of pavement markings the regulation of air flow is not necessary due to the drying mechanics of the product.
SCOPE
1.1 This test method covers a laboratory procedure for determining the no-pick-up time of pavement markings. The method uses a wheel consisting of a metal cylinder with rubber O-rings. The wheel is rolled down a ramp over a freshly applied pavement marking film repeatedly until there is no transfer of the marking material to the rubber rings. The elapsed time from pavement marking film application to point of no marking material transfer is the no-pick-up time. Key variables to be controlled during testing are wet film thickness, temperature, humidity, air flow, and use of retroreflective optics. This standard provides three options for the testing of the no-pick-up time for pavement markings. The first option, Method A, specifies controls for temperature, humidity, and air flow during testing; a second option, Method B, specifies controls for temperature and humidity during testing, and a third option, Method C, provides guidance for performing this with a drop on application of retroreflective optics such as glass beads, Waterborne and Solvent Borne pavement markings are typically tested using Procedure A or Procedure B, without the application of drop on retroreflective optics. Pavement markings that are two component 100 % solids are typically tested using Method C.  
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
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.

Standard Specification for Thermoplastic Pavement Markings in Non Snow Plow Areas

ABSTRACT
This specification covers reflectorized thermoplastic based pavement striping material of the class that is applied to the road surface in a molten state by screed/extrusion or ribbon extrusion means. It deals with longitudinal applications in non snow plow areas, standard (non-profile) pavement marking applications, and applications on smooth asphalt or concrete surfaces. It does not include asphalt seal coat applications, which use large aggregate resulting in a very rough, open grade finish. This specification establishes requirements with respect to chemical composition and physical property of the thermoplastic pavement marking material, requirements for the optics that are used to reflectorize the thermoplastic pavement marking material after application, field performance requirements for the installed thermoplastic pavement markings, and material application requirements.
SCOPE
1.1 This specification covers a reflectorized thermoplastic-based pavement striping material of the class that is applied to the road surface in a molten state by screed/extrusion or ribbon extrusion means. Retroreflectivity of the pavement marking compound is achieved initially by surface application of retroreflective optics at the time of pavement marking application. Upon cooling to normal pavement temperature, the pavement marking material produces an adherent reflectorized stripe of specified thickness and width capable of resisting deformation by traffic. The pavement marking compound includes retroreflective optics (glass beads or composite optics, or both) that are incorporated into the material at the time of manufacture that provide retroreflective properties during the service life of the material.  
1.1.1 This specification is limited to:
1.1.1.1 Longitudinal applications in non snow plow areas,
1.1.1.2 Standard (non-profile) pavement marking applications, and
1.1.1.3 Applications on smooth asphalt or concrete surfaces. Asphalt seal coat applications, which use large aggregate resulting in a very rough, open grade finish, are excluded from this specification.  
1.1.2 This specification includes:
1.1.2.1 Compositional and physical property requirements of the thermoplastic pavement marking material,
1.1.2.2 Requirements for the optics that are used to reflectorize the thermoplastic pavement marking material after application,
1.1.2.3 Field performance requirements for the installed thermoplastic pavement markings, and
1.1.2.4 Material application requirements.  
1.2 The values stated in inch-pounds units are to be regarded as the standard except where noted in the document. 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.
