4.1 In order to choose the proper material for producing semiconductor devices, knowledge of material properties such as resistivity, Hall coefficient, and Hall mobility is useful. Under certain conditions, as outlined in the Appendix, other useful quantities for materials specification, including the charge carrier density and the drift mobility, can be inferred.1.1 These test methods cover two procedures for measuring the resistivity and Hall coefficient of single-crystal semiconductor specimens. These test methods differ most substantially in their test specimen requirements.1.1.1 Test Method A, van der Pauw (1) 2—This test method requires a singly connected test specimen (without any isolated holes), homogeneous in thickness, but of arbitrary shape. The contacts must be sufficiently small and located at the periphery of the specimen. The measurement is most easily interpreted for an isotropic semiconductor whose conduction is dominated by a single type of carrier.1.1.2 Test Method B, Parallelepiped or Bridge-Type—This test method requires a specimen homogeneous in thickness and of specified shape. Contact requirements are specified for both the parallelepiped and bridge geometries. These test specimen geometries are desirable for anisotropic semiconductors for which the measured parameters depend on the direction of current flow. The test method is also most easily interpreted when conduction is dominated by a single type of carrier.1.2 These test methods do not provide procedures for shaping, cleaning, or contacting specimens; however, a procedure for verifying contact quality is given.NOTE 1: Practice F418 covers the preparation of gallium arsenide phosphide specimens.1.3 The method in Practice F418 does not provide an interpretation of the results in terms of basic semiconductor properties (for example, majority and minority carrier mobilities and densities). Some general guidance, applicable to certain semiconductors and temperature ranges, is provided in the Appendix. For the most part, however, the interpretation is left to the user.1.4 Interlaboratory tests of  these test methods (Section 19) have been conducted only over a limited range of resistivities and for the semiconductors, germanium, silicon, and gallium arsenide. However, the method is applicable to other semiconductors provided suitable specimen preparation and contacting procedures are known. The resistivity range over which the method is applicable is limited by the test specimen geometry and instrumentation sensitivity.1.5 The values stated in acceptable metric units are to be regarded as the standard. The values given in parentheses are for information only. (See also 3.1.4.)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 and health practices and 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 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.

This test method is intended for use in comparing the bond strengths (under the given conditions) of masonry mortars, as determined in accordance with Test Method C 1072.This test method could be used, for example, to check one aspect of the quality of mortar products after production, or to indicate the bond potential of a mortar product without requiring the product to be tested in combination with many different units.This test method uses controlled conditions of fabrication and curing that are not intended to represent field conditions.This test method uses standard concrete masonry units. Mortars are batched by weight equivalents of volume proportions and are mixed to a prescribed flow. Prisms are constructed using a jig and are bag-cured.Flexural bond strength determined by this test method shall not be interpreted as the flexural bond strength of a wall (because standard units are not used for wall construction), nor shall it be interpreted as an indication of extent of bond for purposes of water permeability evaluation.1.1 These test methods cover the evaluation of flexural bond strength, normal to the bed joints, of masonry built of manufactured masonry units, as determined in accordance with Test Method C 1072. Sampling and testing procedures are referenced, and terms are defined. Two different test methods are specified, each for a different purpose:1.1.1 The first test method is the “Test Method for Laboratory-Prepared Specimens.” Its purpose is to compare the bond strengths (under the given conditions) of masonry mortars. It could be used, for example, to check the quality of mortar products after production, or to indicate the bond strength (under the given conditions) of a mortar product without requiring the product to be tested in combination with many different units. It is not intended to represent field conditions. It uses standard concrete masonry units. Mortars are batched by weight equivalents of volume proportions and are mixed to a prescribed flow. Prisms are constructed using a jig and are bag-cured.Note 1—Standard fired clay masonry units are under development but are not now available. When their development is complete, they will be incorporated into these test methods.1.1.2 The second test method is the “Test Method for Field-Prepared Specimens.” Its purpose is to evaluate the bond strength (under the given conditions) of a particular unit-mortar combination, either for preconstruction evaluation of materials or for quality control purposes during construction. Mortars are batched conventionally, and the flow is not prescribed. Prisms are constructed conventionally (no jig) and are bag-cured.1.1.3 The two test methods are not consistent, nor are they intended to be. They are intended to be used for two different purposes. To make this clear, the two methods are presented separately.1.1.4 Appendix X1 suggests two possible criteria for assessing the bond strength values obtained using these test methods. These possible evaluation criteria are given for illustration only and are not mandatory.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 and health practices and determine the applicability of regulatory limitations prior to use.

1.1 This guide covers the functional elements and data records of prehospital Health Status Information Services (HSIS) needed to provide individual health status data for HSIS subscribers. When an HSIS subscriber experiences a medical emergency and becomes an EMS patient, a prehospital EMS care provider can rapidly access the individual's health status data by means of telecommunications. Access to this data will enable the EMS provider to improve patient assessment, and thereby render more appropriate treatments. This will improve the EMS provider's ability to stabilize trauma and other emergency medical conditions, and to restore and sustain vital functions, while avoiding treatments that may aggravate the severity of the medical emergency because of preexisting conditions.1.2 In addition to improving on-site assessment, this guide will facilitate improved on-line medical direction of prehospital EMS care providers, particularly for persons experiencing life threatening medical emergencies.1.3 Health status records provide a chronology of a person's health/medical data, including past diagnosis and treatments. The data in these records provide a vital link between the person experiencing a medical emergency, the EMS care provider, and subsequent emergency services. In order to provide the most informed care, EMS care providers and persons providing EMS medical direction need to be aware of the injured or ill person's health status.1.4 This guide describes the minimum requirements for compiling, updating, computerizing, and storing individual's longitudinal health status data in authorized repositories, so as to protect patient privacy and confidentiality. This guide also describes requirements for providing authorized access and rapid transmittal of the data to attending EMS care providers in medical emergencies.1.5 While this guide addresses data needed for prehospital EMS, there is also a recognized essential, but largely unmet need for similar patient health status records for emergency medical care of patients in hospital emergency departments and in definitive medical care facilities. Many development projects are in process to address this unmet need. When available, such patient records are reviewed by attending physicians, in advance of hospital emergency medical care, to quickly access patient health status data that is needed for improved patient assessment and treatment and avoidance of treatments which may be contraindicated by preexisting conditions.1.5.1 Future changes to this guide will result in health status information records for prehospital emergency medical care and analogous information systems for hospital emergency medical care, harmonized with each other and with future standards for computerized longitudinal health care patient records (see Guides E 1744 and F 1629) which are being developed by ASTM Committee E31.1.5.2 This guide describes requirements that are based on current ASTM medical informatics standards and will be updated to harmonize with future versions of these rapidly evolving standards.1.6 The scope of this guide includes harmonization of the definitions of prehospital emergency medical services data element definitions used in this guide with definitions used in other ASTM standards. The definition of data elements in this guide will be the same as the definition of the data element in other ASTM standards. In cases where a data element used in this guide does not appear in another ASTM standard, the guide will use the definition specified for federal health services information systems (4, 5).
