4.1 This guide is intended for use by those undertaking the development of fire-hazard-assessment standards. Such standards are expected to be useful to manufacturers, architects, specification writers, and authorities having jurisdiction.4.2 As a guide, this document provides information on an approach to the development of a fire hazard standard; fixed procedures are not established. Limitations of data, available tests and models, and scientific knowledge may constitute significant constraints on the fire-hazard-assessment procedure.4.3 While the focus of this guide is on developing fire-hazard-assessment standards for products, the general concepts presented also may apply to processes, activities, occupancies, and buildings.4.4 When developing fire-risk-assessment standards, use Guide E1776. The present guide also contains some of the guidance to develop such a fire-risk assessment standard.1.1 This guide covers the development of fire-hazard-assessment standards.1.2 This guide is directed toward development of standards that will provide procedures for assessing fire hazards harmful to people, animals, or property.1.3 Fire-hazard assessment and fire-risk assessment are both procedures for assessing the potential for harm caused by something–the subject of the assessment–when it is involved in fire, where the involvement in fire is assessed relative to a number of defined fire scenarios.1.4 Both fire-hazard assessment and fire-risk assessment provide information that can be used to address a larger group of fire scenarios. Fire-hazard assessment provides information on the maximum potential for harm that can be caused by the fire scenarios that are analyzed or by any less severe fire scenarios. Fire-risk assessment uses information on the relative likelihood of the fire scenarios that are analyzed and the additional fire scenarios that each analyzed scenario represents. In these two ways, fire-hazard assessment and fire-risk assessment allow the user to support certain statements about the potential for harm caused by something when it is involved in fire, generally.1.5 Fire-hazard assessment is appropriate when the goal is to characterize maximum potential for harm under worst-case conditions. Fire-risk assessment is appropriate when the goal is to characterize overall risk (average severity) or to characterize the likelihood of worst-case outcomes. It is important that the user select the appropriate type of assessment procedure for the statements the user wants to support.1.6 Fire-hazard assessment is addressed in this guide and fire-risk assessment is addressed in Guide E1776.1.7 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.8 This fire standard cannot be used to provide quantitative measures.1.9 This standard is used to predict or provide a quantitative measure of the fire hazard from a specified set of fire conditions involving specific materials, products, or assemblies. This assessment does not necessarily predict the hazard of actual fires which involve conditions other than those assumed in the analysis.1.10 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.

The purpose of this practice is to provide guidance to owners, mechanics, airports, regulatory officials, and aircraft and component manufacturers who may accomplish maintenance, repairs, and alterations on a light unmanned aircraft system (UAS). In addition, this practice covers the format and content of maintenance manuals and instructions for the maintenance, repair, and alteration of light UAS. The light UAS can be operated as a commercial aircraft or as a sport aircraft. This practice states the requirements for the maintenance of light commercial UAS. These same requirements may be used for the sport light UAS with the provisions shown. The maintenance requirements are divided between the aircraft and the ground equipment. The aircraft contains the air data terminal and the ground station controls the nearby ground data terminal. Therefore, the data link is not listed as a separate component, but has elements in the aircraft and near the ground station that is called the ground data terminal.1.1 This practice provides guidelines for the qualifications to accomplish the various levels of maintenance on certificated light unmanned aircraft system (UAS). In addition, it provides the content and structure of maintenance manuals for aircraft, ground control station, and data links that are operated as a light unmanned aircraft system (UAS).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.

4.1 The ASTM guidance manual, Form and Style for ASTM Standards,4 Section A21, requires a precision and bias statement in all ASTM test methods. Section A21.2.2 states:  Precision shall be estimated in accordance with the interlaboratory test program prescribed in Practice E691, Conducting an Interlaboratory Study to Determine the Precision of a Test Method, or by an interlaboratory test program that yields equivalent information, for example, a standard practice developed by an ASTM technical committee.4.2 Practice D2777, Section 1.1, states:  This practice establishes uniform standards for estimating and expressing the precision and bias of applicable test methods for Committee D19 on Water. Statements of precision and bias in test methods are required by the Form and Style for ASTM Standards, “Section A21. Precision and Bias (Mandatory).” In principle, all (ASTM Committee D19) test methods are covered by this practice.4.3 Practice D2777, Section 1.2, requires a task group proposing a new test method to carry out a collaborative study from which concentration limits, repeatability and reproducibility precision and bias statements are developed.4.3.1 This guide describes options for developing and optimizing chemical test methods for Committee D19, not implementation of a test method by a laboratory. Refer to Guide E2857 for procedures used in validating existing test methods for your laboratory.4.3.2 The collaborative study described in Practice D2777 is not the test method validation. The collaborative study verifies the new test method is reproducible among different laboratories, different instruments/apparatus, and different analysts.4.3.3 Practice D2777, Section 6.1, assumes the test method has already been optimized prior to conducting the collaborative study.4.4 Practice D2777, Section 4 (Summary of Practice), requires, a collaborative study only after the task group has assured itself that preliminary evaluation work is complete and the test method has been written in its final form.4.5 Practice D2777, Section 5.2 (), requires the collaborative test corroborates the test method write up (preliminary evaluation) within the limits of the test design.4.5.1 The assumption is that the collaborative study is a fair evaluation of the inter-laboratory variability when using the test method to analyze the matrices, and concentration ranges specified in the test method.4.6 Practice D2777, Section 6 (Preliminary Studies), requires considerable pilot work on a test method should precede the determination of precision and bias (collaborative study). This pilot work evaluates such variables as:4.6.1 Representative Sampling,4.6.2 Suitability of containers,4.6.3 Preservation requirements,4.6.4 Identification of interferences,4.6.5 Holding times (Practice D4841),4.6.6 Concentration range,4.6.7 Quantitation ranges,4.6.8 Concentration and preparation of reagents,4.6.9 Reagent standardization,4.6.10 Shelf life of reagents,4.6.11 Calibration,4.6.12 QC, and4.6.13 Sample size.4.7 Potentially significant factors are investigated in advance and are controlled in the written test method that is distributed for the collaborative test.4.8 Only after the proposed test method has been thoroughly tried and proved and reduced to unequivocal written form should a collaborative test be conducted.4.9 The Committee D19 test method is written in two steps:4.9.1 Step I—Single laboratory characterization or optimization (Practice D2777, Section 6.3.1.1).4.9.2 Step II—Collaborative study (Practice D2777, Section 6.3.1.2).4.10 This document is a guide to Committee D19 task groups developing chemical test methods.1.1 This guide identifies procedures for use in developing and optimizing new or modified Subcommitees D19.05 and D19.06 test methods intended for regulatory compliance reporting in EPA drinking water and wastewater programs. This guide may also be useful for developing test methods for emerging contaminants that may not yet have regulatory requirements.1.2 This guide also cites statistical procedures that are useful in the single laboratory characterization and optimization and in the inter-laboratory studies (ILSs).1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.4 This guide offers an organized collection of information or a series of options and does not recommend a specific course of action. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this guide may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project’s many unique aspects. The word “Standard” in the title of this document means only that the document has been approved through the ASTM consensus process.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.

3.1 Trajectory models are used to predict the future movement and fate of oil (forecast mode) in contingency planning, in exercises and during real spill events. This information is used for planning purposes to position equipment and response personnel in order to optimize a spill response. Oil-spill trajectory models are used in the development of scenarios for training and exercises. The use of models allows the scenario designer to develop incidents and situations in a realistic manner.3.2 Oil-spill trajectory models can be used in a statistical manner (stochastic mode) to identify the areas that may be impacted by oil spills.3.3 In those cases where the degree of risk at various locations from an unknown source is needed, trajectory models can be used in an inverse mode to identify the sources of the pollution (hindcast mode).3.4 Models can also be used to examine habitats, shorelines, or areas to predict if they would be hit with oil from a given source (receptor mode).1.1 This practice describes the features and processes that should be included in an oil-spill trajectory and fate model.1.2 This practice applies only to oil-spill models and does not consider the broader need for models in other fields. This practice considers only computer-based models, and not physical modeling of oil-spill processes.1.3 This practice is applicable to all types of oil in oceans, lakes, and rivers under a variety of environmental and geographical conditions.1.4 This practice applies primarily to two-dimensional models. Consideration is given to three-dimensional models for complex flow regimes.1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.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.

4.1 Composite materials consist by definition of a reinforcement phase in a matrix phase. In addition, carbon-carbon composites often contain measurable porosity which interacts with the reinforcement and matrix. The composition and structure of the C-C composite are commonly tailored for a specific application with detailed performance requirements. The tailoring involves the selection of the reinforcement fibers (composition, properties, morphology, etc), the matrix (composition, properties, and morphology), the composite structure (component fractions, reinforcement architecture, porosity structure, microstructure, etc.), and the fabrication conditions (forming, assembly, forming, densification, finishing, etc.). The final engineering properties (physical, mechanical, thermal, electrical, etc.) can be tailored across a broad range with major directional anisotropy in the properties.4.2 Specifications for specific C-C composite components covering materials, material processing, and fabrication procedures are developed to provide a basis for fabricating reproducible and reliable structures. Designer/users/producers have to write C-C composite specifications for specific applications with well-defined composition, structure, properties and processing requirements. But with the extensive breadth of selection in composition, structure, and properties in C-C composites, it is virtually impossible to write a "generic" composite specification applicable to any and all C-C composite applications that has the same type of structure and details of the commonly-used specifications for metal alloys. This guide is written to assist the designer/user/producer in developing a comprehensive and detailed material specification for a specific CMC application/component with a particular focus on nuclear applications.4.3 The purpose of this guide is to provide guidance on how to specify the constituents, the structure, the desired engineering properties (physical, chemical, mechanical, durability, etc), methods of testing, manufacturing process requirements, the quality assurance requirements, and traceability for C-C composites for nuclear reactor applications. The resulting specification may be used for the design, production, evaluation, and qualification of C-C composites for structures in nuclear reactors.4.4 The guide is applicable to C-C composites with flat plate, rectangular bar, round rod, and round tube geometries.4.5 This guide may also be applicable to the development of specifications for C-C composites used for other structural applications, discounting the nuclear-specific chemical purity and irradiation behavior requirements.1.1 This document is a guide to preparing material specifications for fiber reinforced carbon-carbon (C-C) composite structures (flat plates, rectangular bars, round rods, and tubes) manufactured specifically for structural components in nuclear reactor core applications. The carbon-carbon composites consist of carbon/graphite fibers (from PAN, pitch, or rayon precursors) in a carbon/graphite matrix produced by liquid infiltration/pyrolysis and/or by chemical vapor infiltration.1.2 This guide provides direction and guidance for the development of a material specification for a specific C-C composite component or product for nuclear reactor applications. The guide considers composite constituents and structure, physical and chemical properties, mechanical properties, thermal properties, performance durability, methods of testing, materials and fabrication processing, and quality assurance. The C-C composite materials considered here would be suitable for nuclear reactor core applications where neutron irradiation-induced damage and dimensional changes are a significant design consideration. (1-4)21.3 The component specification is to be developed by the designer/purchaser/user. The designer/purchaser/user shall define and specify in detail any and all application-specific requirements for necessary design, manufacturing, and performance factors of the ceramic composite component. This guide for material specifications does not directly address component/product-specific issues, such as geometric tolerances, permeability, bonding, sealing, attachment, and system integration.1.4 This guide is specifically focused on C-C composite components and structures with flat panel, solid rectangular bar, solid round rod, or tubular geometries.1.5 This specification may also be applicable to C-C composites used for other structural applications discounting the nuclear-specific chemical purity and irradiation behavior factors.1.6 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.8 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 The test method enables strength values for wood and other materials bonded with an adhesive under a range of controlled bonding temperature, time, and pressure conditions to be evaluated. Bond formation and subsequent testing is affected in a coordinated fashion, and this enables transient strength values of sets of similar bond types to be explored with diverse parameters as independent variables. Principal among these variables is the temperature at which bonds are formed and the time that selected temperatures are maintained prior to testing. The use of controlled methods of adhesive application, the rapid attainment of stable bond formation conditions, and the rapid transition to the bond testing mode enables snapshots of bond strength to be attained as bonds progress from limited strength (or initial tack) to maximum strength. Derived data may be used to evaluate and compare the strength development characteristics of diverse types and formulations of adhesive. The method may thus be used to aid in tailoring and matching adhesives to the manufacture of diverse bonded products that involve heating.4.2 The method may also be used to evaluate the co-dependent effect of temperature and time on the degradation of sample bonds. Pressing temperatures up to 265°C (509°F) may be necessary for such investigations of thermal degradation. Specimens are pressed for a range of times and temperatures and very shortly thereafter tested either at elevated temperature or immediately following rapid forced air cooling. Alternatively, thermal damage of pre-formed bond samples may be evaluated by subjecting them to controlled temperature and time sequences prior to testing.4.3 The method may also be used to evaluate the effect of wood type and variability, or of non-wood materials, on bond strength development.4.4 By hermetically sealing the overlap region of sample bonds during their formation, the method may also be used to evaluate the effect of moisture and other resident volatile fluids on bond strength development.4.5 The method may also be used to evaluate the effect that the temperature at which variously formed bonds are tested has on their strength. Controlled rapid forced air cooling immediately after bond formation but before testing is necessary for such investigations. This approach may be employed to explore the thermoplastic characteristic of thermosetting adhesives and also the strength of hot melt adhesives as a function of pressing and testing temperatures.1.1 This test method concerns bonding and testing of wood adhesives and related adhesives using small scale tensile lap-shear samples in a manner that emphasizes transient cohesive strength as a function of bonding time and temperature.1.2 Use of thin adherends enables bondlines to be rapidly heated to elevated temperatures and maintained at those temperatures for a range of times at a controlled pressure before testing.1.3 Optional rapid forced air cooling of bonds after pressing and immediately before testing enables the effect of testing temperature on transient strength to be evaluated.1.4 Bond overlap distance is specified to ensure that failure occurs in the bondline rather than in unbonded portions of adherend strips, and also to minimize the effect of shear stress non-uniformity along the overlap during tensile testing.1.5 Standard wood or alternative non-standard materials must be of specified high quality and uniformity of structure and dimension to minimize variability of bonding and maximize stress transfer into the bonds during testing.1.6 The effect of wood variability and type, or of the properties of alternative non-wood materials, on bond strength development may be explored using the method.1.7 Optional hermetic sealing of bond overlaps during their heated pressing enables the effect of moisture on bonding to be evaluated.1.8 Thermal damage, either of pre-formed bonds or by prolonging bond forming times, may be evaluated as a function of time and elevated temperature using this test method.1.9 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.10 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. Some specific hazards statements are given in Section 10 on Hazards.1.11 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 colorant sometimes fails to disperse completely in a base paint due to poor compatibility, which can be the fault of the colorant, the paint, or both. This will result in poor color development, which is readily manifested by the common procedure of applying the paint with a doctor blade and subjecting the drawdown to high shear stress by finger-rubbing a small area of the partially dry film. This tends to disperse undeveloped colorant, if any, and produces a color variation between the unsheared and sheared areas of the paint film. The variation can be measured colorimetrically to give a numerical color difference value that is a measure of the color development of the original paint, the smaller the difference the better the color development and vice versa. Color difference values obtained by finger-rubbing were found to vary widely for the same as well as among different operators. This test method establishes a controlled shear-stress procedure analogous to the finger rub-up test, but with far better reproducibility.5.2 Poor color development can be a problem in the production of paints, and in their performance in the field. In production it causes a loss of colorant monetary value, and unpredictable tinting results. In field performance it results in color variations in the applied paint film due to the varying shear forces to which the paint is subjected at different stages or by different modes of application.5.3 Although poor color development is primarily and most often related to the colorant portion of a tinted paint, the white pigment in the base paint can also be poorly developed due to flocculation or other causes. In the latter case, shear dispersion can make the paint film lighter and less colorful, rather than the reverse. Then too, the colorant and the white might both be poorly developed, and the color change due to shear stress would then be the combined effect of both.5.4 In any case, color development is an important paint property, for the measurement of which this test method is intended to provide a generally accepted and reproducible test method.1.1 This test method covers a procedure for measuring color development in tinted latex paints, for the purpose of determining the efficiency of colorants, the tintability of base paints and the potential for poor color uniformity of applied paint films.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. The values stated in SI units are to be regarded as standard.
