J1166_201409
This SAE Standard sets forth the procedures to be used in measuring sounds levels and determining the time weighted sound level at the operator's station(s) of specified off-road self-propelled work machines. This document applies to the following work machines which have operator stations as specified in SAE J1116: • Crawler Loader • Grader • Log Skidder • Wheel Loader • Crawler Tractor with Dozer • Pipelayer • Dumper • Wheel Tractor with Dozer • Trencher • Tractor Scraper • Backhoe • Sweeper • Roller/Compactor • Hydraulic Excavator • Pad Foot Wheel Compactor with Dozer • Excavator and Wheel Feller-Buncher The instrumentation requirements and specific work cycles for these machines are described. The method used to calculate the time weighted average sound level at the operator station(s) is specified for Leq(5), or optional exchange rates, during continuous operation in a work cycle representing continuous medium to heavy work. The work cycles provide a repeatable reproduceable means to uniformly measure working machines against a “yard stick.

J3078/4
J3078/4 specifies a uniform test method for measuring the contribution to operator environmental temperature provided by a heating, ventilating and air conditioning system operating in a specific ambient environment. The method might not determine the complete climatic environment of the operator since this is also affected by heat load from sources other than those on the machine, for example solar heating. J3708/6 is to be used in conjunction with J3078/4 to determine more accurately the complete heat loading on the operator enclosure. Minimum performance levels for the machine’s operator enclosure heating, ventilating and air conditioning systems are established in J3708/4.

Abstract The installation of essential systems into aircraft wings involves numerous labour-intensive processes. Many human operators are required to perform complex manual tasks over long periods of time in very challenging physical positions due to the limited access and confined space. This level of human activity in poor ergonomic conditions directly impacts on speed and quality of production but also, in the longer term, can cause costly human resource problems from operators' cumulative development of musculoskeletal injuries. These problems are exacerbated in areas of the wing which house multiple systems components because the volume of manual work and number of operators is higher but the available space is reduced. To improve the efficiency of manual work processes which cannot yet be automated we therefore need to consider how we might redesign systems installations in the enclosed wing environment to better enable operator access and reduce production time. This paper describes a recent study that applied design for assembly and maintainability principles and CATIA v5 computer aided design software to identify small design changes for wing systems installation tasks.

This SAE Aerospace Standard (AS) covers the requirements and technical guidance for evaluation of life-cycle cost, productivity, and safety/health factors related to power hand tool selection. It applies approaches to selection of quieter and lower vibration hand-held powered tools, with optimal ergonomic features, for the prevention of Hand-Arm Vibration Syndrome (HAVS), hearing loss and repetitive motion injuries. It suggests use of noise and vibration data provided by vendors to be verified and supplemented by information available through the National Institute for Occupational Safety and Health (NIOSH) and European Union databases. Inclusion/exclusion of data in this document is not intended to imply that all of the products described herein are the only production models that meet this standard. Consumers are requested to consult with manufacturers concerning lists of stock production models that meet this standard. Guidance for selection, procurement and maintenance of power hand tools should be one component of management processes supporting productivity, reliability and product quality while safe guarding the safety and health of employees.

This document applies to both Original Equipment Manufacturer and aftermarket route-guidance and navigation system functions for passenger vehicles. It establishes two alternative procedures, a static method and an interrupted vision method, for determining which navigation and route guidance functions should be accessible to the driver while the vehicle is in motion. These methods apply only to the presentation of visual information and the use of manual control inputs to accomplish a navigation or route guidance task. The document does not apply to visual monitoring tasks which do not require a manual control input, such as route following. Voice-activated controls or passenger operation of controls are also excluded. There are currently no compelling data that would support the extension of this document to in-vehicle systems other than navigation systems.
