SNM monitors are an efficient and sensitive means of unobtrusively (without a body search) meeting the requirements of 10 CFR (Code of Federal Regulations) Part 73 or DOE Order 5632.4 (May 1986) that individuals exiting nuclear material access areas (MAAs) be searched for concealed SNM. The monitors sense radiation emitted by SNM, which is an excellent but otherwise imperceptible clue to the presence of the material. Because the monitors operate in a natural radiation environment and must detect small intensity increases as clues, the monitors must be well designed and maintained to operate without unnecessary nuisance alarms. This guide provides information on different types of monitors for searching pedestrians and vehicles. Each monitor has an inherent sensitivity at a particular nuisance alarm rate that must be low enough to maintain the monitor’credibility. Sensitivity and nuisance alarm rates are both governed by the alarm threshold so it is very important that corresponding values for both be known when measured, estimated, or specified values are discussed. Fitting SNM monitors into a facility physical protection plan must not only consider adequate sensitivity but also a sufficiently low nuisance alarm rate.1.1 This guide briefly describes the state-of-the-art of radiation monitors for detecting special nuclear material (SNM) (see 3.1.11) in order to establish the context in which to write performance standards for the monitors. This guide extracts information from technical documentation to provide information for selecting, calibrating, testing, and operating such radiation monitors when they are used for the control and protection of SNM. This guide offers an unobtrusive means of searching pedestrians, packages, and motor vehicles for concealed SNM as one part of a nuclear material control or security plan for nuclear materials. The radiation monitors can provide an efficient, sensitive, and reliable means of detecting the theft of small quantities of SNM while maintaining a low likelihood of nuisance alarms. 1.2 Dependable operation of SNM radiation monitors rests on selecting appropriate monitors for the task, operating them in a hospitable environment, and conducting an effective program to test, calibrate, and maintain them. Effective operation also requires training in the use of monitors for the security inspectors who attend them. Training is particularly important for hand-held monitoring where the inspector plays an important role in the search by scanning the instrument over pedestrians and packages or throughout a motor vehicle. 1.3 SNM radiation monitors are commercially available in three forms: 1.3.1 Small Hand-Held Monitors—These monitors may be used by an inspector to manually search pedestrians and vehicles that stop for inspection. 1.3.2 Automatic Pedestrian Monitors—These monitors are doorway or portal monitors that search pedestrians in motion as they pass between radiation detectors, or wait-in monitoring booths that make extended measurements to search pedestrians while they stop to obtain exit clearance. 1.3.3 Automatic Vehicle Monitors—These monitors are portals that monitor vehicles as they pass between radiation detectors, or vehicle monitoring stations that make extended measurements to search vehicles while they stop to obtain exit clearance. 1.4 Guidance for applying SNM monitors is available as Atomic Energy Commission/Nuclear Regulatory Commission (AEC/NRC) regulatory guides, AEC/ERDA/DOE performance standards, and more recently as handbooks and applications guides published by national laboratories under DOE sponsorship. This broad information base covering the pertinent physics, engineering practice, and equipment available for monitoring has had no automatic mechanism for periodic review and revision. This ASTM series of guides and standards will consolidate the information in a form that is reexamined and updated on a fixed schedule. 1.5 Up-to-date information on monitoring allows both nuclear facilities and regulatory agencies to be aware of the current range of monitoring alternatives. Up-to-date information also allows manufacturers to be aware of the current goals of facilities and regulators, for example, to obtain particular sensitivities at a low nuisance alarm rate with instrumentation that is dependable and easy to maintain. 1.6 This guide updates and expands the scope of NRC regulatory guides and AEC/ERDA/DOE SNM monitor performance standards using the listed publications as a technical basis. 1.7 The values stated in SI units are to be regarded as the standard. 1.8 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems 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.

4.1 A major concern for administration officials is security of barriers used in detention/correctional facilities. These test methods are designed to identify the security levels for ventilation grilles mounted within these barriers.4.2 The purpose of these tests is to approximate levels of abuse to which grilles will potentially be subjected in the field, and to provide assurance of protection to the public, facility administrative personnel, and inmates.1.1 These test methods cover requirements for simulated service tests and testing equipment for determining the performance characteristics of ventilation grilles used in secure areas, including detention and correctional facilities. The testing equipment provides for the setup and testing of specimen grilles and mounting systems. It is recognized that, in order to meet the intent of these test methods, ventilation grilles must be compatible with the level of performance require by Test Methods F2322.1.2 It is the intent of these test methods to ensure that security ventilation grilles meet minimum performance levels to control the passage of unauthorized materials into secure areas, to confine inmates, to resist vandalism, and to delay or frustrate escape, or both. It is also the responsibility of the user of these test methods to insure that the grille selected is appropriate, based on relevant regulatory, health, and safety concerns and requirements. Such concerns include, but are not limited to, injury and suicide avoidance. These test methods do not quantify such concerns.1.3 Take care to provide access to return and exhaust ducts for cleaning as required by NFPA 90A. If access cannot be provided though an interstitial space behind walls or ceiling, the use of filter grilles needs to be considered as an option. When filter grilles are provided, filters shall have a minimum UL-900 class 2 rating, and a filter replacement program needs to be in place at the facility.1.4 Airflow performance shall be catalogued in accordance with ASHRAE 70–91. Manufacturer’s catalog data must include grade level achieved.1.5 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.1.6 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.

4.1 Physical constants of paints and coatings are required in all aspects of their formulation, manufacture and use. This practice demonstrates standard methods agreed upon for calculating formulation values for some of these physical constants. The calculations are the same for either metric or inch/pound units.4.2 These formula values may not be used to replace measured values required by government regulations unless specifically stated in the governing documents.4.3 Some regulations allow compliance determination using formulation data instead of analytical data. This formulation data may not yield the same results as the required analytical method, which could be performed on a sample from any production batch of the coating. In these cases, the user may wish to compare formulation data to analytical data and develop a factor that adjusts for variability of raw materials, variability of production batches, cure volatiles, and variability of the analytical methods.1.1 This practice covers procedures commonly used in the paint industry to formulate paints and coating materials. It describes procedures for calculating formulation values for weight solids, volume solids, solvent content, volatile organic compound (VOC) content, hazardous air pollutant (HAP) content, and density of liquid paints and coatings. These values are calculated from basic formulation data. These calculations may be related to either as-supplied (unreduced) or as-applied (reduced) coating materials, including multicomponent types.1.2 These calculated, formulation-based values may or may not be acceptable for VOC regulatory purposes, depending on the specific wording of the applicable regulation. Some regulations require analysis of the coating. Some rules allow the use of formulation data, however, some adjustments may be needed to the values calculated in this practice before they are used for regulatory purposes (see 4.3).1.3 For purposes of this practice, it is assumed that volatile components evaporate and the materials that remain are identified as coating solids. For example, solvents are normally used to adjust viscosity for application and appearance of the coating. Other liquid materials, such as plasticizers, reactive diluents, etc., that are expected to be retained in the dried film to affect the final physical properties should be classified as part of the coating solids. Standards such as Test Methods D2369, D4758, D5403, and Guide D2832 may be used to determine volatile or nonvolatile content of specific components. For purposes of this practice it is assumed that the blended formulation behaves as an ideal solution with no volume change on mixing (see 6.2).1.4 Volatile by-products of cross-linking reactions (cure volatiles) are not considered in these calculations since the object of this practice is to define paint physical constants based on formulation information. Variations in raw materials, variations in the production processes, test methods, and test method accuracy are not taken into account in these calculations.1.5 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. However, they may be readily converted into SI units, if required by the user (for example, see Note 4).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.

5.1 A nano-object is an individual, well-defined, and separable piece of a nanomaterial; in practice, nanomaterials used in research, products, testing, and other uses are usually collections of nano-objects. Individual nano-objects and collections of nano-objects are the two major types of nanomaterials in use. The description of an individual nano-object is covered in this guide; the description of collections of nano-objects (for example, two or more individual nano-objects) is not covered in this guide.5.2 Nanomaterials are of growing importance in research and commerce, and data on their physical and chemical characteristics are critical to predict performance, to transact commercial activities, to assess their potential for harm to human and animal health and the environment in general, and to support regulations that affect their use. To describe nanomaterials, whether for research or commerce, it is important to be able to describe an individual nano-object.5.3 When in a liquid environment, a nano-object may attract a non-permanent “halo” of water or other solvent molecules; such a non-permanent halo is not described by the present guide.5.4 In contrast, coatings and coronas are semi-permanent or permanent adherents on time scales commensurate with testing procedures; coatings and coronas can fundamentally transform one nano-object to another in terms of its characteristics and can be described using this guide.5.5 The four types of data and information used to describe a nano-object are: physical and chemical characteristics; production; specifications; and general identifiers (names and classifications), as shown in Fig. 1.5.6 This guide deals solely with data and information to describe the physical and chemical characterization of an individual nano-object.NOTE 2: Other guides and documents (see Section 2, Referenced Documents) deal with the data and information for production, specifications, and general identifiers (names and classifications).NOTE 3: Specifications are formal or informal documents that provide guidance on specifying the composition, structure, or any other aspect of a nano-object.5.7 In a practical sense, the amount of data and information reported to describe the physical and chemical characteristics differs widely depending on who is reporting and the reason they are reporting. Researchers examining specific aspects of a nano-object may choose to report a limited subset of characteristics. A test report on the potential toxicity of a nano-object may choose to report numerous characteristics. This guide supports both limited and complete reporting of the characteristics enumerated herein.5.8 The science of characterizing nano-objects is still evolving. Some information categories will require additional descriptors as new knowledge is developed. Some descriptors may become obsolete. Users should consult the latest guide for the most complete recommendations.5.9 The technology for collecting, storing, analyzing, and disseminating scientific and technical data continues to evolve, and tools such as ontologies, database schemas, data repository reporting requirements, and data recoding formats are evolving similarly. This guide provides a clear, English language definition of information categories and descriptors used to describe an individual nano-object that can be used in these and other similar tools.5.10 A nano-object has properties and functionalities that are measured under specific measurement conditions. The description of a nano-object requires data and information on its properties as well as on the conditions under which those properties were measured, as shown in Fig. 2. The description of the data and information necessary to describe properties and functionalities as well as the procedure, which specify the measurement conditions under which the properties and functionalities are measured, are described in other guides and standards.5.11 The characteristics of an individual nano-object defined in this guide address the important physical and chemical properties of that nano-object. Because the techniques and instruments used to measure these properties can greatly influence the property value, when available, the measurement result being used should include as much information as possible about the measurement conditions.1.1 This guide provides guidelines for a description system for reporting the physical and chemical characteristics of individual nano-objects. It establishes information categories and descriptors useful in describing individual nano-objects uniquely and such that the equivalency of two or more individual nano-objects can be determined according to specific criteria.1.2 This guide is designed to be directly applicable to reporting the physical and chemical characteristics of nano-objects in every circumstance, including but not limited to reporting original research results in the archival literature, developing ontologies, database schemas, data repositories, and data reporting formats, specifying regulations, and enabling commercial activity.1.3 This guide is applicable to naturally-occurring, engineered, and manufactured nano-objects.1.4 One goal of the guide is to help ensure that when measurement results are reported, they are reported uniformly.1.5 A second goal of the guide is to encourage reports on the properties and functionalities of a nano-object to include as much detail as possible about the physical and chemical characteristics of that nano-object so it is uniquely specified.1.6 This guide does not cover the chemical reactions or reactivity of a nano-object.1.7 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.8 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.1.9 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 By following the procedures specified in this guide, any item of physical evidence will have a traceable audit trail by which the origin, past history, treatment, and analysis of the item can be determined.4.2 By following these procedures, the chain of custody of any item of physical evidence will be maintained and documented.1.1 This guide describes methods to be used for labeling physical evidence collected during field investigations; received in a forensic laboratory; or isolated, generated, or prepared from items submitted for laboratory examination.1.2 Many types of physical evidence may be hazardous. It is assumed that personnel assigned to the collection, packaging, storing, or analysis of physical evidence will take precautions as appropriate to the evidence.1.3 This guide offers a set of instructions for performing one or more specific operations. This standard cannot replace knowledge, skill, or ability acquired through appropriate education, training, and experience and should be used in conjunction with sound professional judgment.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use.

5.1 This practice is intended for use by those in the waste management industries to aid in describing the physical characteristics of waste.5.2 This practice has two uses. One is to visually screen wastes being received at the laboratory to identify discrepancies between the waste, manifest, and historical descriptions. The other use is to visually examine soil and water samples while they are being collected. This information, along with professional judgment during sample collection, can be used to increase the knowledge of the site contamination by increasing or reducing the number of samples collected based on visible indication of contamination or lack of visible indication of contamination. For example, if a soil or groundwater sample is collected “up gradient” of the area of known or suspected contamination to obtain site background concentrations, and the sample appears contaminated, the up-gradient area can be relocated during that sampling event. Visual observation could also show that the sampling parameters need to be increased or decreased. This may reduce or eliminate the need for additional sampling trips to the field.1.1 This practice is used to identify wastes by describing certain physical properties. It has been developed as a rapid but effective means for visually screening wastes when received in the laboratory or during collection at the sampling site.1.2 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.

7.1 The particle size distribution of powdered ion exchange resins and, more importantly, the derived parameters of mean particle size and percent above and below specified size limits are useful for determining batch to batch variations and, in some cases, can be related to certain aspects of product performance.7.2 Although automatic multichannel particle size analyzers, of the type described in Section 9, yield information on the entire distribution of sizes present in a given sample, it has been found that, for this application, the numerical value of three derived parameters may adequately describe the particle size characteristics of the samples: the mean particle diameter (in micrometres), the percent of the sample that falls below some size limit, and the percent of the sample that falls above some size limit.1.1 These test methods cover the determination of the physical and chemical properties of powdered ion exchange resins and are intended for use in testing new materials.
