The purpose of this practice is to provide the minimum requirements necessary for the establishment of a quality assurance and production acceptance program for a manufacturer of light airplane UAS.1.1 This practice establishes the minimum requirements for the development of a Quality Assurance and Production Acceptance Program, to be used for the manufacture of Light Airplane Unmanned Aircraft Systems (UAS).1.2 Other documents relevant to this practice include Practice F 2279, 14 CFR Part 21, 14 CFR Part 23, and 14 CFR Part 43.1.3 This standard does not purport to address the quality assurance of the data-links, autopilot functions, and control stations.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 specification covers particulate glass (cullet material) recovered from waste destined for disposal, smaller than 6 mm intended for reuse as a raw material in the manufacture of glass containers. Flint glass cullet is a particulate glass material that contains no more than 0.1 weight % Fe2O3, or 0.0015 weight % Cr2O3, as determined by chemical analysis. The color mix for amber, flint, green and other color glass cullet shall conform to the prescribed mix.1.1 This specification covers particulate glass (cullet material, recovered from waste destined for disposal, smaller than 6 mm intended for reuse as a raw material in the manufacture of glass containers.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.2.1 Exception—The values given in parentheses are for information only.1.3 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 This specification provides designers and manufacturers of electric propulsion for light sport aircraft design references and criteria to use in designing and manufacturing EPUs.3.2 Declaration of compliance is based on testing and documentation during the design, ground testing and flight testing of the EPU by the manufacturer or under the manufacturers’ guidance.3.3 Manufacturers of the EPUs are encouraged to review and incorporate appropriate standards and lessons learned from ground based systems as documented in SAE J2344 and EASA CRI F-58 (see Appendix X2).3.4 Electric aircraft may contain potentially hazardous level of electrical voltage or current. It is important to protect persons from exposure to this hazard. Under normal operating conditions, adequate electrical isolation is achieved through physical separation means such as the use of insulated wire, enclosures, or other barriers to direct contact. There are conditions or events that can occur outside normal operation that can cause this protection to be degraded. Some means should be provided to detect degraded isolation or ground fault. In addition, processes or hardware, or both, should be provided to allow for controlled access to the high voltage system for maintenance or repair. A number of alternative means may be used to achieve these electrical safety goals including automatic hazardous voltage disconnects, manual disconnects, interlock systems, special tools and grounding. The intention of all these means is either to prevent inadvertent contact with hazardous voltages or to prevent damage or injury from the uncontrolled release of electric energy. Lightning strikes are not addressed in this Standard Practice because LSA aircraft are limited to VMC flight only.1.1 This practice covers minimum requirements for the design and manufacture of Electric Propulsion Units (EPU) for light sport aircraft, VFR use. The EPU shall as a minimum consist of the electric motor, associated controllers, disconnects and wiring, an Energy Storage Device (ESD) such as a battery or capacitor, or both, and EPU monitoring gauges and meters. Optional onboard charging devices, in-flight charging devices or other technology may be included.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.1.3 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.

This practice covers the design, material grouping classification, and manufacture of wire image quality indicators (IQI) used to indicate the quality of radiologic images. This practice, applicable to X-ray and gamma-ray radiology, covers the use of wire penetrameters as the controlling image quality indicator for the material thickness range from 6.4 to 152 mm [0.25 to 6.0 in.]. The alloy group(s) of the material, the thickness or thickness range of the material, and the applicable IQI's that represent the required IQI thickness(s) and alloy(s) shall be considered when selecting IQI's.1.1 This practice2 covers the design, material grouping classification, and manufacture of wire image quality indicators (IQI) used to indicate the quality of radiographic images.1.2 This practice is applicable to X-ray and gamma-ray radiography.1.3 This practice covers the use of wire penetrameters as the controlling image quality indicator for the material thickness range from 6.4 to 152 mm (0.25 to 6.0 in.).1.4 The values stated in inch-pound units are to be regarded as standard.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.
