Proposal to delete text requiring integration of electrical current at 20 Hz from GTR 21 para. 5.2.1., simplify requirements for determining and verifying K1 and K2 factors in para. 6.1.1.1. and 6.1.1.2. by deleting redundant sentences and SAE J2907, adding conditional manufacturer reporting on K factor determination, and add a note to para. 5.2.1. stating specific humidity need not be measured unless ICE power correction per para. 6.9.3.2. is applied.
Document compares human body model (HBM) capabilities with anthropomorphic test device (ATD) limitations. HBMs enable assessment at lower impact speeds, evaluation of older occupants with age-dependent material properties, checking belt fit across multiple anthropometries, assessment of restraint system interaction with different body shapes, evaluation of varying postures including non-upright hip angles, consideration of pre-crash phase effects on in-crash phase, and addressing injury types limited by ATD sensor availability and biofidelity. HBMs can be used omnidirectionally if validated, whereas ATDs are limited to design range and single loading direction. Harmonization work is needed for active HBMs, anthropometric agreement, belt fit criteria, and spine curvature validation.
Working draft proposal for a 04 series of amendments to UN R51, establishing specifications for sound emission measurement and limits. The regulation sets sound level limits varying by vehicle category, mass, and power output, ranging from 68 to 79 dB(A). It includes methods for measuring vehicle sound outdoors and indoors, specifications for test conditions including vehicle mass, speed, and acceleration, requirements for sound reduction systems and exhaust silencing, transitional provisions, and Real Driving Additional Sound Emission Provisions (RD-ASEP) for M1 and N1 vehicles with specific exemptions based on engine capacity, payload, mass, and power-to-mass ratio.
