4.1 Conditioning is used to minimize the variation in test results that may result from fluctuations in temperature and humidity, or both. Many flexible packaging materials or components of flexible packaging materials, particularly materials that are hygroscopic, undergo changes in physical properties as the temperature and the relative humidity (RH) to which they are exposed are varied.4.2 Many packaging materials do not exhibit a meaningful change in physical properties across the temperature and humidity range that is generally found in office and general laboratory settings. As a result, conditioning of samples is often not required in order to achieve useful test results and is often bypassed during routine testing.4.3 Conditioning should be considered when (a) comparing between or among laboratory results (for example, supplier and customer), (b) temperature or humidity is anticipated to have an effect on the test outcomes, or (c) potential sources of variation in test results must be minimized.4.4 Temperature and humidity alone are not sufficient to completely define a storage condition. Many other factors may be relevant (such as time, light, and atmospheric pressure) that are not defined in this specification.AbstractThis specification defines the standard temperature and humidity for conditioning and testing of materials at nominally ambient conditions. Materials for conditioning and testing include material containing paper and plastic material. The instruments and techniques used to measure these standard conditions of temperature and humidity must be validated.1.1 This practice defines the standard temperature and humidity for conditioning and testing of flexible barrier packaging and flexible barrier packaging materials at nominally ambient conditions.1.2 There are many other temperature and humidity conditions that may be appropriately used to test end use conditions (such as freezer, refrigerated, or abusive storage). These need to be individually established and are not in the scope of this practice.1.3 Only those materials that fall under the general area of flexible barrier packaging materials are included in this practice.1.4 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.1.5 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.

1.1 This specification covers marketing, packaging, labeling, and warning requirements for adult magnet sets containing small, powerful magnets. It is aimed at minimizing the identified hazards to children and teens associated with ingesting small, powerful magnets that are intended for adults, that is, those persons 14 years of age and older.1.2 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.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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 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 For criticality control of nuclear fuel in dry storage and transportation, the most commonly used neutron absorber materials are borated stainless steel alloys, borated aluminum alloys, and boron carbide aluminum alloy composites. The boron used in these neutron absorber materials may be natural or enriched in the nuclide 10B. The boron is usually incorporated either as an intermetallic phase (for example, AlB2, TiB2, CrB2, etc.) in an aluminum alloy or stainless steel, or as a stable chemical compound particulate such as boron carbide (B4C), typically in an aluminum MMC or cermet.4.2 While other neutron absorbers continue to be investigated, 10B has been most widely used in these applications, and it is the only thermal neutron absorber addressed in this standard.4.3 In service, many neutron absorber materials are inaccessible and not amenable to a surveillance program. These neutron absorber materials are often expected to perform over an extended period.4.4 Qualification and acceptance procedures demonstrate that the neutron absorber material has the necessary characteristics to perform its design functions during the service lifetime.4.5 The criticality control function of neutron absorber materials in dry cask storage systems and transportation packagings is only significant in the presence of a moderator, such as during loading of fuel under water, or water ingress resulting from hypothetical accident conditions.4.6 The expected users of this standard include designers, neutron absorber material suppliers and purchasers, government agencies, consultants and utility owners. Typical use of the practice is to summarize practices which provide input for design specification, material qualification, and production acceptance. Adherence to this standard does not guarantee regulatory approval; a government regulatory authority may require different tests or additional tests, and may impose limits or restrictions on the use of a neutron absorber material.1.1 This practice provides procedures for qualification and acceptance of neutron absorber materials used to provide criticality control by absorbing thermal neutrons in systems designed for nuclear fuel storage, transportation, or both.1.2 This practice is limited to neutron absorber materials consisting of metal alloys, metal matrix composites (MMCs), and cermets, clad or unclad, containing the neutron absorber boron-10 (10B).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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.4 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 Harmful biological or particulate contaminants may enter the medical package through leaks. These leaks are frequently found at seals between package components of the same or dissimilar materials. Leaks may also result from a pinhole in the packaging material.4.2 It is the objective of this test method to visually observe the presence of channel defects by the leakage of dye through them.4.3 This dye penetrant procedure is applicable only to individual leaks in a package seal. The presence of a number of small leaks, as found in porous packaging material, which could be detected by other techniques, will not be indicated.4.4 There is no general agreement concerning the level of leakage that is likely to be deleterious to a particular package. However, since these tests are designed to detect leaks, components that exhibit any indication of leakage are normally rejected.4.5 These procedures are suitable to verify and locate leakage sites. They are not quantitative. No indication of leak size can be inferred from these tests. The methods are usually employed as a pass/fail test.4.6 The dye solution will wick through any porous material over time, but usually not within the maximum time suggested. If wicking does occur, it may be verified by observing the porous side of the subject seal area. The dye will have discolored the surface of the material. Refer to Appendix X1 for details on wicking and guidance on the observance of false positives.1.1 This test method defines materials and procedures that will detect and locate a leak equal to or greater than a channel formed by a 50 µm (0.002 in.) wire in package edge seals formed between a transparent material and a porous sheet material. A dye penetrant solution is applied locally to the seal edge to be tested for leaks. After contact with the dye penetrant for a specified time, the package is visually inspected for dye penetration.1.2 Three dye application methods are covered in this test method: injection, edge dip, and eyedropper.1.3 These test methods are intended for use on packages with edge seals formed between a transparent material and a porous sheet material. The test methods are limited to porous materials which can retain the dye penetrant solution and prevent it from discoloring the seal area for a minimum of 5 seconds. Uncoated papers are especially susceptible to leakage and must be evaluated carefully for use with each test method.1.4 These test methods require that the dye penetrant solution have good contrast to the opaque packaging material.1.5 The values are stated in International System of Units (SI units) and English units. Either is to be regarded as 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.

5.1 Introduction of robots to the responder's cache for use in urban search and rescue missions may have an impact on the logistical planning for the response teams. Additional volume and weight shall be stored and transported to the response site. Additional preparation time shall be allotted to ready the robot for deployment. The tools that are taken to the field may need to be augmented to service the robots. Once the robot is ready for deployment, it shall be transported from the base of operations to the mission zone. Responders may have to carry the robot and its controller or may have to provide some other transportation mechanism if it is too heavy.5.2 This practice is designed to appraise the impact in terms of logistical considerations for a response organization.1.1 This practice covers the requirement that urban search and rescue robots and all necessary associated components or equipment (for example, operator control station, power sources, spare parts, sensors, manipulators, tools, and so forth) shall complement the response organization’s cache packaging and transportation systems.1.2 Shipment by ground, air, or marine should be considered.1.3 Volume, weight, shipping classification, and deployability of the robots and associated components are considered in this practice.1.3.1 The deployability is considered through the determination of:1.3.1.1 The length of time required to prepare the robot system for deployment, and1.3.1.2 The types of tools required for servicing the robot system in the field.1.3.2 Associated components or equipment include not only all the onboard sensors, tethers, and operator control station, but also any spare parts and specialized tools needed for assembly, disassembly, and field servicing.1.3.3 Associated components also include power equipment necessary for the operation of the system, such as batteries, chargers, and power converters. Gasoline, diesel, or other types of liquid fuel are not included.1.4 The packaged items shall support the operational availability of the robot during a deployment of up to ten days. There shall be no resupply within the first 72 h of deployment.1.5 No such standards currently exist except for those relevant to shipping (for example, CFR Title 49 and International Air Transport Association (IATA) documents).1.6 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.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.
