4.1 Most organic liquids and solids will ignite in a pressurized oxidizing gas atmosphere if heated to a sufficiently high temperature and pressure. This procedure provides a numerical value for the temperature at the onset of ignition under carefully controlled conditions. Means for extrapolation from this idealized situation to the description, appraisal, or regulation of fire and explosion hazards in specific field situations, are not established. Ranking of the ignition temperatures of several materials in the standard apparatus is generally in conformity with field experience.4.2 The temperature at which material will ignite spontaneously (AIT) will vary greatly with the geometry of the test system and the rate of heating. To achieve good interlaboratory agreement of ignition temperatures, it is necessary to use equipment of approximately the dimensions described in the test method. It is also necessary to follow the described procedure as closely as possible.4.3 The decomposition and oxidation of some fully fluorinated materials releases so little energy that there is no clear-cut indication of ignition. Nor will there be a clear indication of ignition if a sample volatilizes, distilling to another part of the reaction vessel, before reaching ignition temperature.1.1 This test method covers the determination of the temperature at which liquids and solids will spontaneously ignite. These materials must ignite without application of spark or flame in a high-pressure oxygen-enriched environment.1.2 This test method is intended for use at pressures of 2.1 MPa to 20.7 MPa [300 psi to 3000 psi]. The pressure used in the description of the method is 10.3 MPa [1500 psi], and is intended for applicability to high pressure conditions. The test method, as described, is for liquids or solids with ignition temperature in the range from 60 °C to 500 °C [140 °F to 932 °F].NOTE 1: Test Method G72/G72M normally utilizes samples of approximately 0.20 ± 0.03-g mass, a starting pressure of 10.3 MPa [1500 psi] and a temperature ramp rate of 5 °C/min. However, Autogenous Ignition Temperatures (AIT) can also be obtained under other test conditions. Testing experience has shown that AIT testing of volatile liquids can be influenced by the sample pre-conditioning and the sample mass. This will be addressed in the standard as Special Case 1 in subsection 8.2.2. Testing experience has also shown that AIT testing of solid or non-volatile liquid materials at low pressures (that is, < 2.1 MPa) can be significantly influenced by the sample mass and the temperature ramp rate. This will be addressed in the standard as Special Case 2, in subsection 8.2.3. Since the AIT of a material is dependent on the sample mass/configuration and test conditions, any departure from the standard conditions normally used for Test Method G72/G72M testing should be clearly indicated in the test report.1.3 This test method is for high-pressure pure oxygen. The test method may be used in atmospheres from 0.5 % to 100 % oxygen.1.4 An apparatus suitable for these requirements is described. This test method could be applied to higher pressures and materials of higher ignition temperature. If more severe requirements or other oxidizers than those described are desired, care must be taken in selecting an alternative safe apparatus capable of withstanding the conditions.1.5 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.1.6 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 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.

Health information networks (HINs) have arisen in recent years as a way to share common information within organizational arrangements among those healthcare facilities that have been formed into large, more comprehensive integrated delivery systems (IDS) and managed care organizations (MCO) offering a full range of healthcare services, both inpatient and ambulatory.The specific organizational structures to which the MCO term was originally applied most probably have evolved into something quite different. Furthermore, IDS organizations are contracting with other organizations that have a market larger than a single IDS itself and are buying such services for themselves rather than offering them internally.These organizations will need a frame of reference for the global information needed to provide all of the services required during patient care. For a global Concept Model consult ADA Specification 1000.0–1000.18 and TR 1039.Pharmacotherapy will require a number of these services, including those of the clinical laboratory for therapeutic drug monitoring as well as pharmacy services of both resident and nonresident care organizations and stand-alone pharmacies to ensure freedom from medication errors and conduct ongoing investigations of both the outcomes of care and the management of resources related to pharmacotherapy.Pharmacotherapy functions include prescribing (clinical orders), dispensing, administering, and monitoring, which support “pharmaceutical care” defined as “provision of drug therapy to achieve desired therapeutic outcomes that improve a patient’s quality of life.” These functions address patients’ needs that require information support as noted in Table 1.Another aspect of the monitoring function is the development of instrumentation for testing at point of care (POCT) for high-value immediate-benefit services that support pharmacotherapy. POCT, however, needs supervision and training from skilled laboratorians for the actual performers, whether that supervision comes from within the IDS or outside of it. This range of operation is only achievable by distributed HIN structures that shall have the same quality of clinical and data services as offered by laboratories close at hand. Data management of POCT is documented separately (see CLSI POCT1, ASTP2), but such data management for support of pharmacotherapy shall be placed into the broader context of this practice and linked to CLSI LIS-9A. Thus, this practice should be used to first organize the global domain and then the interconnected subdomains.1.1 This practice applies to the process of defining and documenting the capabilities, logical data sources, and pathways of data exchange regarding pharmacotherapy information services within a given network architecture serving a set of healthcare constituents.1.2 This practice is not a technical implementation standard but, rather, describes how the implementation methods and techniques can be used to coordinate pharmacotherapy services logically within an electronic health record (EHR) systems environment involving participating organizations and sites connected by a networked communication system.1.3 This practice covers the content of the nodes and arcs of the resulting logical network involving EHR, pharmacy, and clinical laboratory-capable sites. This practice also considers the various purposes and organizational arrangements for coordinating pharmacotherapy services within the network boundaries and the considerations for connections among external networks.1.4 This practice refers to other standards for conventions within various data domains, such as pharmacy systems, clinical laboratory information management systems (CLIMS), and EHR systems, and for messaging conventions.1.5 This practice is intended to outline how integration of pharmacy, CLIMS, and EHR information systems can be undertaken to result in a transparent pharmacotherapy clinical decision support environment, regardless of the underlying implementation architecture, by describing the logical interoperability of information domains as facilitated by information and communications technology (ICT).1.6 This practice is directed at pharmacists, clinical pharmacologists, clinical laboratorians, information system managers, and information systems vendors for use in planning and implementing coordinated pharmacotherapy services through effective dialog.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 and health practices and determine the applicability of regulatory limitations prior to use.

1.1 This test method is used to determine the degree and rate of aerobic biodegradation of plastic materials exposed to a controlled composting environment. Aerobic composting takes place in an environment where temperature, aeration, and humidity are closely monitored and controlled. 1.2 The test is designed to determine the biodegradability of plastic materials, relative to that of a standard material, in an aerobic environment. Aeration of the test reactors is maintained at a constant rate throughout the test and reactor vessels of a size no greater than 4-L volume are used to ensure that the temperature of the vessels is approximately the same as that of the controlled environment chamber. 1.3 Biodegradability of the plastic is assessed by determining the amount of weight loss from samples exposed to a biologically active compost relative to the weight loss from samples exposed to a "poisoned" control. 1.4 The test is designed to be applicable to all plastic materials that are not inhibitory to the bacteria and fungi present in the simulated Municipal Solid Waste (MSW). 1.5 The values stated in SI units are to be regarded as 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 and health practices and determine the applicability of regulatory limitations prior to use.
