This guide describes the procedures for evaluating and calibrating friction measurement systems known as Continuous Friction Measuring Equipment (CFMEs) using the specialized equipment, instruments, pavement surfaces, trained personnel, and approved facilities. It serves as a process to identify and quantify the variables that affect system performance, to minimize the effect of these variables, and to provide a means to relate CFMEs to reference skid measurement systems. The standard covers the apparatus to be used in evaluation and calibration, physical measurements, static force evaluation and calibration, tire pressure gauge calibration, speed and distance calibration, slip ratio or yaw angle verification, water flow and distribution, force plate calibration, final testing and reporting, documentation, reporting of results, and frequency of system correlation and calibration.1.1 This guide describes the evaluation and calibration of friction measurement systems which are known as Continuous Friction Measuring Equipment (CFMEs). The evaluation and calibration processes, using the specialized equipment, instruments, pavement surfaces, trained personnel, and approved facilities, are performed using the procedures described below.1.2 This guide is offered as a process to identify and quantify the variables that affect system performance, to minimize the effect of these variables, and to provide a means to relate CFMEs to reference skid measurement systems.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.

5.1 Personnel responsible for the creation, display, transfer or storage of digital nondestructive evaluation results will use this guide.5.2 Personnel responsible for the design and manufacture of NDT systems conforming to the DICONDE standard will use this guide.5.3 Personnel responsible for the purchase and implementation of NDT systems conforming to the DICONDE standard will use this guide.5.4 This guide will recommend courses of action for utilizing the DICONDE standard for the use cases described in 5.1, 5.2, and 5.3.1.1 The display, transfer and storage of digital nondestructive evaluation data in a common, open format is necessary for the effective interpretation and preservation of evaluation results. ASTM International has developed common open standards for Digital Imaging and Communication in Nondestructive Evaluation (DICONDE) based on the ubiquitous healthcare industry standard Digital Imaging and Communication in Medicine (DICOM). This guide provides an overview of the ASTM International standard practices that address DICONDE and assistance in identifying the correct standard practices for different use cases.1.2 This document provides an overview of how to utilize the ASTM DICONDE standard practices found in paragraph 2.1.2 on ASTM DICONDE Test Methods Standards for the display, transfer and storage of digital nondestructive test data1.3 This document provides an overview of how to utilize the DICOM standard found in paragraph 2.2 on Other Documents for the display, transfer and storage of digital nondestructive test data for test methods not explicitly addressed by a DICONDE standard practice but having an equivalent medical imaging modality.1.4 This document provides recommendations for the display, transfer and storage of nondestructive digital test data not addressed in 1.2 or 1.3.1.5 This document provides an overview of how to utilize the ASTM DICONDE standard practices found in paragraph 2.1.3 on ASTM DICONDE Interoperability Standards for validating a system that follows the ASTM DICONDE standard for the display, transfer and storage of digital nondestructive test data.1.6 This document provides an overview of how to utilize the ASTM DICONDE standard practices found in 2.1.3 for validating that two or more systems that follow the ASTM DICONDE standard for the transfer of digital nondestructive test data can successfully transfer data.1.7 This document provides an overview of how to utilize the ASTM DICONDE standard practices found in 2.1.3 for validating that two or more systems that follow the ASTM DICONDE standard for the display of digital nondestructive test data display data consistently.1.8 Although this guide contains no values that require units, it does describe methods to store and communicate data that do require units to be properly interpreted. The SI units required by this guide are to be regarded as standard. No other units of measurement are included in this guide.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.1.10 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.

4.1 The test results provide an indication of the turbine-powered nozzle life. The end of turbine life will be judged in accordance with 3.1.1.1.1 This test method covers the turbine-powered nozzle used in household central vacuum cleaning systems.1.2 This test method provides a test for determining the operating turbine life in hours by an accelerated laboratory procedure. The turbine is tested while mounted and operated in the power nozzle.1.3 This test method covers only the turbine-powered nozzle. The system used to provide the airflow source is not under consideration.1.4 This test method is limited to the determination of turbine life for a household turbine-powered nozzle.1.5 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use.

4.1 This guide is intended to aid device fabricators in the selection of proper commercially available polyurethane solids and solutions for their application.4.2 The polyurethanes covered by this guide may be thermoformed or solution cast into biomedical devices for use as surgical aids or for implantation as determined to be appropriate, based on supporting biocompatibility and physical test data.1.1 This guide covers the evaluation of thermoplastic polyurethanes in both solid and solution form for biomedical applications. The polymers have been reacted to completion and require no further chemical processing.1.2 The tests and methods listed in this guide may be referenced in specifications containing minimum required values and tolerances for specific end-use products.1.3 Standard tests for biocompatibility are included to aid in the assessment of safe utilization in biomedical applications. Compliance with these criteria shall not be construed as an endorsement of implantability. Since many compositions, formulations, and forms of thermoplastic polyurethanes in solid and solution forms are within this material class, the formulator or fabricator must evaluate the biocompatibility of the specific composition or form in the intended use and after completion of all manufacturing processes including sterilization.1.4 Purchase specifications may be prepared by agreement between the buyer and seller by selection of appropriate tests and methods from those listed applicable to the specific biomedical end use.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 and health practices and determine the applicability of regulatory limitations prior to use.
