Introduction to SAE J1173-2019 SAE J1173-2019 is a recommended practice that defines the size classification, physical characteristics, and testing procedures for glass beads used in peening processes. This standard ensures that glass beads meet consistent quality requirements for effective and…

SAE J1174-2015 is a SAE Recommended Practice that establishes a uniform procedure for measuring the operator ear sound level of engine-powered equipment under 30 kW (40 bhp). Primarily targeting small outdoor power equipment such as lawn mowers, snow blowers, and…

SAE J1175-2012 was a recommended practice published by SAE International that defined a pass-by noise measurement procedure for small engine powered equipment. Developed in the 1970s, it was intended to measure bystander sound levels during vehicle operation. However, the standard…

SAE J1169-2007 was a surface vehicle standard that established a test procedure, environment, and instrumentation for measuring the exhaust sound level of passenger cars, multipurpose vehicles, and light trucks under stationary conditions. Originally issued in 1977 and revised several times,…

The SAE J1170 standard, revised in 1993, establishes critical specifications and dimensions for 540 rpm and 1000 rpm power take-off (PTO) shafts on agricultural tractors. It covers rear and now also front PTO configurations, ensuring that implements from different manufacturers…

🔍 Test Procedures for External Ignition Protection SAE J1171-2023 specifies test methods to ensure marine electrical devices do not cause ignition under normal or fault conditions. The standard covers three sequential tests: continuous operation for surface temperature, sealed device integrity,…

For decades, SAE J1165 served as a recommended practice for reporting cleanliness levels of hydraulic fluids. However, in May 2012, it was officially cancelled and replaced by the globally accepted ISO 4406 standard. Engineers and designers must now ensure that…

Measuring and comparing operator sound levels across different off-road self-propelled work machines requires a standardized, repeatable approach. SAE J1166 (revised March 2021) provides exactly that – a comprehensive method for determining the time‑weighted average sound level at the operator station…

The SAE J1160-2004 recommended practice establishes a standardized methodology for measuring the noise level at the operator’s ear position for snowmobiles. Although superseded by more recent standards (J192, J1161, and J2567), J1160 remains a foundational reference for understanding the principles…

SAE J1161-2021 provides a uniform test procedure for measuring the exterior operational sound level of snowmobiles. By referencing SAE J192 for instrumentation, test site, data processing, and environmental correction, this standard ensures consistent and repeatable noise assessments across different testing…
