Exposure Levels of UV Radiation in Nondestructive Inspection ProcessesAIR4964A (Current)7/17/2026
Long wave ultraviolet or UV-A irradiation (between 320 and 400 nm) is used for fluorescent inspections in magnetic particle and liquid penetrant examinations. UV-A irradiation is obtained from either LED, fluorescent, or high intensity discharge lamps that are stationary or portable. Commercially available UV-A lamps possess a large variation in intensity output that may introduce a legitimate concern for possible health hazards. This document reviews the nature of UV-A irradiation emitted by lamps and acceptable UV dosage limits adopted by the American Conference of Governmental Industrial Hygienists (ACGIH®) and European Union and recommendation of proper practices when working with UV-A irradiation.

CVJ Efficiency Test Recommended PracticeJ3249_202607 (Current)7/14/2026
This recommended practice describes the procedure to measure and report the operating efficiency for all types of constant velocity joints (including fixed and plunging/end motion type joints) used in cars, SUVs, and trucks. This includes halfshaft as well as propshaft applications. This does not apply to non-CV joints. Rotational inertia is not considered within the scope of this recommended practice. This recommended practice provides a common method to quantify and report the operating efficiency characteristics of a CVJ. This practice does not apply to parasitic losses (spin loss, churning loss, or zero torque loss) as experienced on deactivated AWD/4WD systems. The losses in this condition are significantly less and require higher accuracy than what is required in this recommended practice.

R134a and R1234yf Refrigerant Charge Determination Test MethodJ3023_202607 (Current)7/13/2026
The purpose of this document is to establish guidelines for determining the critical R134a and R1234yf refrigerant charge for off-road, self-propelled work machines as defined in SAE J1116 and agricultural tractors as defined in ANSI/ASAE S390. It will develop a minimum to maximum refrigerant charge range in which the HVAC system can maintain proper operation. Operating conditions and characteristics of the equipment will influence the optimum charge.
