Sound Measurement—Off-Road Work Machines—Exterior
- Ground Vehicle Standard
- J88_200602
- Revised
Scope
Rationale
-
General—Only metric dimensions are used.
-
1—The “Purpose” was eliminated and combined with the “Scope” to conform to the new SAE format which lists “Scope” first.
-
2—References were updated and listed as Section 2 per new SAE format (was Section 5).
-
3.1—Added text to allow the use of an integrating sound level meter if it meets IEC 804-1985 requirements and has the slow dynamic characteristic, max hold.
-
4.2.1.4—Added text to indicate cycled component must have controls located at the operator’s station. Added text to exclude non-riding machines without power steering or hydraulic controls from this section of the test procedure. Also, added text to include self-propelled sweepers into the machine hydraulic cycling component of the test procedure.
-
4.2.2—Added text to identify major component operation for self-propelled sweepers during the constant speed moving test.
-
4.2.3—Included text to identify major attachments for trenching machines and self-propelled sweepers and their proper transport positions.
-
4.3.2—Included Leq as an approved sound level meter setting for recording the steady-state sound levels of high idle and rated speed.
-
4.3.6—Requested gear ratio and approximate ground speed used during the moving test to be recorded.
-
4.3.9—Divided this section into three sections to clarify the number of cycles to be conducted, and the determination of measurement results. New sections added were numbered 4.3.10 and 4.3.12. (Now 4.3.11)
-
4.3.12 (Now 4.3.11)—Added text to permit attachments not considered in defining the basic machine to be left on during testing.
-
5.2—Added text covering safe operation of the machine per the manufacturer’s operating instructions.

Issuing Committee
OPTC3, Lighting and Sound Committee
OPTC3 addresses standards related to sounds, lighting and marking for off-road, self-propelled work machines, and equipment. This committee reports to ConAg Council through OPTC. ConAg Council covers machines described in SAE J1116 which includes machines defined in ISO 6165, ISO 6814, and ISO 22242, with regards to activities supporting; • Creating consensus SAE standards, recommended practices, and information reports • Harmonizing relevant SAE documents with ISO documents • Assisting the US with the creation and maintenance of ISO standards through US TAGs o ISO/TC 127 --- Earth-moving machinery o ISO/TC 195 --- Building construction machinery and equipment o ISO/TC 23/SC 15 --- Machinery for forestry Participants in this committee include OEMs, suppliers, consulting firms, government, and others across the construction and forestry industries.
