4.1 Classification of human land search and rescue resources is based upon the training of the personnel and their ability to perform specific tasks.4.2 Human search and rescue resources are classified by category, kind, and duration.1.1 This classification is intended to identify the common functional units and single resources used in search and rescue operations; to aid search and rescue (SAR) managers and Authorities Having Jurisdiction (AHJs) in assembling or ordering resources for search, rescue, or search and rescue incidents; and to aid in identifying the tasks for which crews have been trained.1.2 This classification is intended as a supplement to the resource typing specifications of the Incident Command System and specifically as a means of typing human resources used in land search and rescue activities.1.3 This classification is suitable for classifying search and rescue crews for land search and rescue incidents.1.4 This classification does not attempt to classify individuals or put forth standards of performance or training for individuals, nor is it meant to convey certification, skill proficiency, or other measures of the level of performance of the resource. These qualifications are the responsibility of the local agencies responsible for utilizing the resource.1.5 This classification identifies human-based resources. Canine crew (or team) classifications are defined in Classification F1848.1.6 This classification does not classify air resources (Guides F2958 and F3026) or water resources (Guides F1739, F1783, and F1824).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.

Biobased materials are considered a means to reduce the consumption of nonrenewable resources and reduce the environmental impact associated with the creation of materials and products, such as increased CO2 emissions and so forth. The U.S. Government has expressed the desire to use its buying power to promote usage of biobased materials, as evidenced in Presidential Orders 13101 and 13123 and the recently passed Farm Security and Rural Investment Act of 2002 (P.O. 107 - 171.).This guide provides a vendor with a standardized process to develop and compile information on the total resources consumed in creation of a product, define what fraction of the resources are biobased, and transmit the information in a clear and logical way. Carbon is the foundation of both biobased and fossil (nonrenewable) resources. Carbon also represents a large fraction of the environmental profile considerations of a product. Therefore carbon is used in this guide to combine and track energy and raw materials resources consumption involved in creation of a product.This guide provides a way to determine and report weight fraction of biobased material in a product, or its biobased content, W(b).This guide also provides for verification and validation of the information supplied by vendors to support their product claims.This guide provides a way to determine the biobased and nonrenewable (fossil) resource consumption, both as raw materials and as energy, involved in creation of a product and to combine the biobased and nonrenewable resources into total resource consumption on a consistent basis.A companion standard5 provides a test method for authentication of the origin of carbon claimed to be derived from renewable resources.1.1 This guide covers a process to determine (1) biobased content of materials and products, (2) total resource consumption, both biobased and nonrenewable, in the form of raw materials and energy, and (3) an environmental profile, which would also include emissions and waste generated.1.2 Reference to the use of factors to convert materials and energy to carbon equivalents are provided (1-6). In addition, the use of ISO standards to determine the material and energy inventories and an environmental profile of the products and materials is discussed. It is outside the scope of this guide to provide a detailed description of the use and application of life cycle assessment tools and conversion factors for the determination of a biobased material's environmental profile. Future ASTM International standards are being prepared to cover these subjects.1.3 In the application of this guide, the protection of business confidential information is an important consideration. In general, the level of detail required to evaluate material and energy inputs and outputs can be reported without revealing proprietary unit process information. Unit processes can be treated as black boxes with inputs and outputs. If business confidentiality is still a concern, unit processes can be further combined or the final LCA (Life Cycle Assessment) results can be reviewed and certified by an external, independent expert with which the vendor will have the appropriate secrecy agreement.

5.1 Traditional methods for expressing geological uncertainty consist of preparing reliability categories based simply on the distance between drill hole data points, such as the one described by Wood et al. (5) that uses only the drill holes within the coal bed. A major drawback of distance methods is their weak to null association with estimation errors. This practice provides a methodology for effectively assessing the uncertainty in coal resource estimates utilizing stochastic simulation. In determining uncertainty for any coal assessment, stochastic simulation enables consideration of other important factors and information beyond the geometry of drill hole locations, both in and out of the coal bed, including: non-depositional channels, depth of weathering, complexity of seam boundaries, coal seam subcrop projections, and varying coal bed geology for different seams due to fluctuating peat depositional environments. Olea et al. (6) explains in detail the methodology behind this practice and illustrates it with an example.5.2 For multi-seam deposits, uncertainty can be expressed on an individual seam basis as well as an aggregated uncertainty for an entire coal deposit.5.3 The uncertainty is expressed directly in tons of coal. Additionally, this practice allows the statistical analysis to be presented according to widely-accepted conventions, such as percentiles and confidence intervals. For example, there is a 90 % probability that the actual tonnage in place is 314 million metric tons ± 28.8 million metric tons (346 million tons ± 31.7 million tons) of coal.5.4 The results of an uncertainty determination can provide important input into an overall risk analysis assessing the commercial feasibility of a coal deposit.5.5 A company may rank coal resources per block (cell) based on the degree of uncertainty.1.1 This practice covers a procedure for quantitatively determining in-place tonnage uncertainty in a coal resource assessment. The practice uses a database on coal occurrence and applies geostatistical methods to model the uncertainty associated with a tonnage estimated for one or more coal seams. The practice includes instruction for the preparation of results in graphical form.1.2 This document does not include a detailed presentation of the basic theory behind the formulation of the standard, which can be found in numerous publications, with a selection being given in the references (1-3).21.3 This practice should be used in conjunction with professional judgment of the many unique aspects of a coal deposit.1.4 Units—The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.NOTE 1: All values given in parentheses after SI units are stated in inch-pound units.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.

1.1 This classification system covers all naturally occurring uranium-bearing materials and is based on level of geologic knowledge and economic producibility of the resource at a given time. 1.2 Assessments of uranium resources are made for two purposes: ( ) to provide aggregate information on the resources of a region or country and ( ) to provide information needed for decisions concerning the resources of specific properties or deposits. 1.3 For regional appraisals, broad categories of uranium resources defined in general terms are the most useful. 1.4 For specific consideration of an individual property or to establish the availability of producible resources for commercial purposes, the terms and definitions used require a narrow construction and place emphasis on reliability and the quantification of mineral values in known deposits.
