ABSTRACT
This specification covers the physical requirements and testing of three types of lap cement for use with asphalt roll roofing. Type I is a brushing consistency lap cement intended for use in the exposed-nailing method of roll roofing application, and contains no mineral or other stabilizers. This type is further divided into two grades, as follows: Grade 1, which is made with an air-blown asphalt; and Grade 2, which is made with a vacuum-reduced or steam-refined asphalt. Both Types II and III, on the other hand, are heavy brushing or light troweling consistency lap cement intended for use in the concealed-nailing method of roll roofing application, only that Type II cement contains a quantity of short-fibered asbestos, while Type III cement contains a quantity of mineral or other stabilizers, or both, but contains no asbestos. The lap cements shall be sampled for testing, and shall adhere to specified values of the following properties: water content; distillation (total distillate at given temperatures); softening point of residue; solubility in trichloroethylene; and strength at indicated age.
SCOPE
1.1 This specification covers lap cement consisting of asphalt dissolved in a volatile petroleum solvent with or without mineral or other stabilizers, or both, for use with roll roofing. The fibered version of these cements excludes the use of asbestos fibers.  
1.2 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 nonconformance with the standard.  
1.3 The following precautionary caveat applies only to the test method portion, Section 6, of this specification: 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
5.1 The kinematic viscosity characterizes flow behavior. The method is used to determine the consistency of liquid asphalt as one element in establishing the uniformity of shipments or sources of supply. The specifications are usually at temperatures of 60 and 135 °C.
Note 3: The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of Specification D3666 are generally considered capable of competent and objective testing, sampling, inspection, etc. Users of this standard are cautioned that compliance with Specification D3666 alone does not completely ensure reliable results. Reliable results depend on many factors; following the suggestions of Specification D3666 or some similar acceptable guideline provides a means of evaluating and controlling some of those factors.
SCOPE
1.1 This test method covers procedures for the determination of kinematic viscosity of liquid asphalts, road oils, and distillation residues of liquid asphalts all at 60 °C [140 °F] and of liquid asphalt binders at 135 °C [275 °F] (see table notes, 11.1) in the range from 6 to 100 000 mm2/s [cSt].  
1.2 Results of this test method can be used to calculate viscosity when the density of the test material at the test temperature is known or can be determined. See Annex A1 for the method of calculation.  
Note 1: This test method is suitable for use at other temperatures and at lower kinematic viscosities, but the precision is based on determinations on liquid asphalts and road oils at 60 °C [140 °F] and on asphalt binders at 135 °C [275 °F] only in the viscosity range from 30 to 6000 mm2/s [cSt].
Note 2: Modified asphalt binders or asphalt binders that have been conditioned or recovered are typically non-Newtonian under the conditions of this test. The viscosity determined from this method is under the assumption that asphalt binders behave as Newtonian fluids under the conditions of this test. When the flow is non-Newtonian in a capillary tube, the shear rate determined by this method may be invalid. The presence of non-Newtonian behavior for the test conditions can be verified by measuring the viscosity with viscometers having different-sized capillary tubes. The defined precision limits in 11.1 may not be applicable to non-Newtonian asphalt binders.  
1.3 Warning—Mercury has been designated by the United States Environmental Protection Agency (EPA) and many state agencies as a hazardous material that can cause central nervous system, kidney, and liver damage. Mercury, or its vapor, may be hazardous to health and corrosive to materials. Caution should be taken when handling mercury and mercury-containing products. See the applicable product Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) for details and the EPA’s website—http://www.epa.gov/mercury/faq.htm—for additional information. Users should be aware that selling mercury, mercury-containing products, or both, in your state may be prohibited by state law.  
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 nonconformance with the standard.  
1.5 The text of this standard 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 the standard.  
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 determine the applicability of regulatory limitations prior ...

SIGNIFICANCE AND USE
4.1 Flash X-ray facilities provide intense bremsstrahlung radiation environments, usually in a single sub-microsecond pulse, which often fluctuates in amplitude, shape, and spectrum from shot to shot. Therefore, appropriate dosimetry must be fielded on every exposure to characterize the environment, see ICRU Report 34. These intense bremsstrahlung sources have a variety of applications which include the following:
(1) Studies of the effects of X-rays and gamma rays on materials.
(2) Studies of the effects of radiation on electronic devices such as transistors, diodes, and capacitors.
(3) Computer code validation studies.  
4.2 This guide is written to assist the experimenter in selecting the needed dosimetry systems for use at pulsed X-ray facilities. This guide also provides a brief summary on how to use each of the dosimetry systems. Other guides (see Section 2) provide more detailed information on selected dosimetry systems in radiation environments and should be consulted after an initial decision is made on the appropriate dosimetry system to use. There are many key parameters which describe a flash X-ray source, such as dose, dose rate, spectrum, pulse width, etc., such that typically no single dosimetry system can measure all the parameters simultaneously. However, it is frequently the case that not all key parameters must be measured in a given experiment.
SCOPE
1.1 This guide provides assistance in selecting and using dosimetry systems in flash X-ray experiments. Both dose and dose rate techniques are described.  
1.2 Operating characteristics of flash X-ray sources are given, with emphasis on the spectrum of the photon output.  
1.3 Assistance is provided to relate the measured dose to the response of a device under test (DUT). The device is assumed to be a semiconductor electronic part or system.  
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
