1.1 This practice provides for the establishment and maintenance of calibration procedures for measuring and test equipment used for electrical insulating materials. It provides a framework of concepts and practices, with definitions and specifications pertaining to measurement, adequacy of standards, necessary environmental controls, tables of corrections, intervals of calibration, calibration procedures, calibration of standards, and personnel training system documentation.1.2 This practice is intended for control of the accuracy of the equipment used for measurements that are made in accordance with ASTM standards or other specified requirements.1.3 The values stated in metric units are regarded as the standard. The values in inch-pound or English units are for information only.1.4 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.

This guide has been prepared to aid in the writing of material standards using the Classification D 4000 format.1.1 This classification system covers ___ materials suitable for _____________. The inclusion or exclusion of recycled plastics in this classification system must be addressed here.1.2 The properties included in this standard are those required to identify the compositions covered. Other requirements necessary to identify particular characteristics important to specialized applications are to be specified by using suffixes as given in Section 5.1.3 This classification system and subsequent line callout (specification) are intended to provide a means of calling out plastic materials used in the fabrication of end items or parts. It is not intended for the selection of materials. Material selection can be made by those having expertise in the plastic field only after careful consideration of the design and the performance required of the part, the environment to which it will be exposed, the fabrication process to be employed, the costs involved, and the inherent properties of the material other than those covered by this standard.NOTE 1: Insert Note 1 here to show the appropriate ISO equivalency statement.1.4 The following precautionary caveat pertains only to the test method portion, Section 11, of this classification system: 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.1.5 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.

4.1 This guide is intended to be used to assess competencies of qualified individuals who wish to become (a) certified in basic aircraft certification knowledge and (b) those who wish to earn advanced degrees as an aerospace engineering certification specialist through an accredited collegiate program.4.2 This guide is intended to be used in concert with a certification provider’s structure and materials for management, exam delivery, and candidate preparation.4.3 This can also be an educational steppingstone to becoming an individual designee or an organizational delegation authority unit member (UM), or both.1.1 The purpose of this guide is to address the fundamental subject and content knowledge requirements and outcomes of aircraft certification educational training courses for engineers and professionals in the aerospace industry. The content may be more broadly applicable. The standards envisioned within this guide are intended to be usable globally.1.2 Background—The standards envisioned within this guide are intended to be usable globally. There are certification requirements specific to each country’s respective civil aviation authority (CAA) (for example, published guidance from applicable CAA) concerning the acceptable use and application thereof. For example, some engineering approval processes vary from country to country. Regardless of an engineering process’s name or description, to the maximum extent possible, the standards to be developed from this guide should account for engineering approvals that support aircraft certification globally.1.2.1 Through education standards that are created and accepted by CAAs and industry, engineers and professionals in the aerospace industry will have the knowledge and skills necessary to successfully carry out aircraft design certification projects using these standards for professional training and curriculum accreditation. Compliance data will be developed by engineers who have gained foundational knowledge in aircraft certification through training developed according to globally recognized consensus standards.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.
