5.1 This is intended to outline O&M issues that require discussion and mutual agreement by both the optical fiber cable owner and sewer pipeline operator. The purpose is developing sufficient written procedures and practices to allow optical fiber systems to coexist as a secondary use within a sewer. To the extent that sewers are primarily for conveying flow, it is the responsibility of the optical fiber cable owner to accommodate sewer O&M practices and develop optical fiber system O&M procedures that will not material impact the sewer’s primary function.5.2 Since the practice of integrating sewers and optical fiber systems is an emerging activity, this practice will help establish guidelines for its rapid and safe deployment, ensuring that the installed facilities are operable as intended on a long-term basis.1.1 This practice applies to the operation and maintenance of sewers with a subsequent installation of optical fiber cable in accordance with Practice F2303.1.2 This practice applies to gravity flow storm sewers, sanitary sewers, and combined sewers.1.3 This practice does not apply to force mains, siphons, or other pressurized sewers.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use.

3.1 This practice not only provides information on the accumulated effects of corrosion at specific time periods under a given set of conditions, but also provides information on the initial rate of corrosion of virgin metal, the corrosion rate of metal per unit time after long exposure, and the initial corrosion rate of virgin metal after long exposure of the corroding fluid to metal. The test also provides a means of determining the direction corrosion will take with time, although causes for increase or decrease in the corrosiveness and corrodibility of media and metal (such as passive film formation or destruction, depletion of corrosive contaminate, and so forth) as a function of time are not given.1.1 This practice covers the determination of the corrosiveness of tank-type aircraft maintenance chemicals on aircraft metals and the corrodibility of metals in these maintenance chemicals with time. The determination is made under conditions of total immersion by a combination of weight change measurements and visual qualitative determinations of change.1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.

4.1 This industry-developed standard may be used as a guide in developing AMT/AME curriculum programs to help ensure enhanced knowledge and skill levels for the maintenance technician/engineer in today’s ever-changing and highly technical aviation environment.1.1 The primary purpose of this guide is to address the fundamental subject knowledge, task performance, and task knowledge activities, labeled ‘Core Competencies,’ that ensures the Aircraft Maintenance Technician/Maintenance Engineer (AMT/AME) have the necessary basic knowledge and skills for today’s global aviation maintenance environment. Thus, the ASTM F46 Aerospace Personnel Committee has developed academic and skills knowledge standards that have been developed by aerospace industry-lead working groups. These standards reflect industry best practices and provide a focus on levels of safety that may exceed current regulatory guidance for aircraft maintenance technician academic and skills standards. This guide may supplement a state’s basic general requirements for AMT/AME certification. It is not the intent of this guide to replace the basic or general requirements, but to ensure the AMT/AME is trained on these core competencies to the level as indicated. This guide may be used as a basis for an approval when specifically identified as such by the appropriate governing authority. Parts of this guide may also be referenced by other aerospace personnel groups seeking training, educational, qualification, or certification standards. (See Guide F3245; 14 CFR Part 147; EASA Annex IV, Part 147; NFPA 407; OSHA The Globally Harmonized System for Hazard Communication.)1.2 An applicant intending to propose this guide as a Means of Compliance for the AMT/AME who works on unmanned aircraft systems (UAS) must seek guidance from their respective oversight authority (that is, published guidance from applicable CAA’s) concerting the acceptable use and application thereof. For information on unmanned aircraft systems, refer to ASTM Committee F38 at www.astm.org/COMMITTEE/F38.htm.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 Proper installation is critical to effective performance of silt fence. This practice presents procedures for installing and maintaining silt fence that have been shown to result in silt fence installations that effectively redirect and impound surface runoff and, thereby, provide effective sediment control.NOTE 1: The quality of the result produced by this standard is dependent on the competence of the personnel performing it, and the suitability of the equipment and facilities used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection/etc. Users of this standard are cautioned that compliance with Practice D3740 does not in itself assure reliable results. Reliable results depend on many factors; Practice D3740 provides a means of evaluating some of those factors1.1 This practice covers common installation and maintenance procedures for temporary silt fence applications. This practice is based on AASHTO M288.1.2 This practice is applicable to the use of silt fence as a vertical permeable interceptor designed to remove suspended soil from overland, non-concentrated water flow. The function of a temporary silt fence is to trap and allow settlement of soil particles from sediment laden water by intercepting and impounding water in an effort to slow the transport velocity and provide storage for sediment to be captured. The purpose is to greatly limit the transport of eroded soil from the construction site by water runoff.1.3 The practices presented herein are intended to ensure good workmanship and quality, but do not necessarily apply to the concentrated flow applications.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 practice 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.1.6 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.
