ALARM - BACKUP - ELECTRIC - PERFORMANCE, TEST, AND APPLICATION
1985-03-01
HISTORICAL
J994_198503
This SAE Recommended Practice establishes the following criteria for electrically operated backup alarm devices on mobile construction and industrial machinery: a Backup alarm device performance requirements. b Measurement technique for alarm performance requirements. c Laboratory environmental tests. d Alarm activation on the vehicle.

Alarm - Backup - Electric Laboratory Performance Testing
2023-06-27
CURRENT
J994_202306
The scope of this SAE Standard is the definition of the functional, environmental, and life cycle test requirements for electrically operated backup alarm devices primarily intended for use on off-road, self-propelled work machines as defined by SAE J1116 (limited to categories of (1) construction, and (2) general purpose industrial).
Standard

CRITERIA FOR BACKUP ALARM DEVICES
1971-10-01
HISTORICAL
J994A_197110
The job requirements, along with local, state, or national codes, should dictate whether a backup alarm device shall be used on construction and mobile outdoor industrial machinery. In the cases of those machines which do not distinguish in direction of working travel and where the machine is equipped so the operator can face the direction of travel each time (for example, certain compactors, loaders, and dozers), the use of a backup alarm device may not be applicable.

Discriminating Back-Up Alarm System Standard
2008-12-04
WIP
J1741
This SAE Standard describes methods for evaluating the performance of the systems detection device, the minimum detection areas behind the machine, the visual and audible information presented to the operator and ground personnel, and the systems fault detection requirements. Also included are operator system function tests and maintenance procedures. The purpose of this document is to establish performance requirements for a Discriminating Back-Up Alarm System.

EXTERIOR SOUND LEVEL MEASUREMENT PROCEDURE FOR EARTHMOVING MACHINERY
1979-04-01
HISTORICAL
J88B_197904
This SAE Standard is applicable to machinery of 15 kw (20 rated bhp) and over. It is not intended to cover operation of safety devices (such as backup alarms). The sound levels obtained by using the test procedures set forth in this SAE Standard are repeatable and are representative of the higher range of sound levels generated by the machinery under actual field operating conditions, but do not necessarily represent the average sound level over a field use cycle.
Standard

EXTERIOR SOUND LEVEL MEASUREMENT PROCEDURE FOR POWERED MOBILE CONSTRUCTION EQUIPMENT
1972-11-01
HISTORICAL
J88_197211
This SAE Recommended Practice sets forth the instrumentation and procedure to be used in measuring exterior sound levels for powered mobile construction equipment of 20 rated bhp and over. It is not intended to cover operation of safety devices (such as backup alarms) and equipment designed primarily for operation on highways or within factories and building areas, aircraft, or recreational vehicles, such as snowmobiles and boats. The sound levels obtained by using the test procedures set forth in this SAE Recommended Practice are repeatable and representative of the sound levels generated by the equipment during normal operating conditions.
Standard

Horn - Forward Warning - Electric - Performance, Test, and Application
2022-08-05
CURRENT
J1105_202208
The scope of this SAE Standard is the definition of the functional, environmental, and life cycle test requirements for electrically operated, operator controlled forward warning horn devices, primarily intended for use on self-propelled, work machines as defined by SAE J1116 (limited to categories of (1) construction and (2) general purpose industrial).
Standard

MEASUREMENT PROCEDURE FOR DETERMINING A REPRESENTATIVE SOUND LEVEL AT A CONSTRUCTION SITE BOUNDARY LOCATION
1978-04-01
HISTORICAL
J1075_197804
This SAE Recommended Practice sets forth procedures and instrumentation to be used for determining a representative sound level during a representative time period at selected measurement locations on a construction site boundary. It concerns the community adjacent to the construction site, and it is not intended for use in determining occupational hearing damage risk.
Standard

OPERATOR SOUND LEVEL MEASUREMENT PROCEDURE FOR EARTHMOVING MACHINERY—SINGULAR TYPE TEST
1979-04-01
HISTORICAL
J919C_197904
This SAE Standard is applicable to machinery of 15 kw (20 bhp) rated and over, that have operator stations where the operator can either stand or sit and will be transported by the machine during its operation. It is not intended for use with agricultural equipment. The sound levels obtained by using the test procedures set forth in this SAE Standard are in general repeatable, and are representative of the higher range of the sound levels generated by the machinery under field operating conditions, but do not necessarily represent the equivalent sound level over a field use cycle. For measurement and calculation of the operator’s sound exposure, use SAE Recommended Practice J1166a.

OPERATOR SOUND LEVEL MEASUREMENT PROCEDURE FOR POWERED MOBILE CONSTRUCTION MACHINERY—SINGULAR TYPE TEST
1976-03-01
HISTORICAL
J919B_197603
This SAE Recommended Practice sets forth the instrumentation and procedures to be used in measuring sound levels at the operator station for powered mobile construction machinery of 15 kW (20 bhp) rated and over. This Recommended Practice is to cover machinery that has operator stations where the operator can either stand or sit and will be transported by the machine during its operation. The sound levels obtained by using the test procedures set forth in this SAE Recommended Practice are in general repeatable and are representative of the higher range of the sound levels generated by the machinery under field operating conditions, but do not necessarily represent the equivalent sound level over a field use cycle.
