I just found a newer document, with a corrected version of 
Recommendation R.1.

IARU Region VHF Managers Handbook

IARU Region 1 Technical Recommendation R.1
BRIGHTON 1981, TORREMOLINOS 1990

STANDARDISATION OF S-METER READINGS

1. One S-unit corresponds to a signal level difference of 6 dB,

2. On the bands below 30 MHz a meter deviation of S-9 corresponds to an
available power of -73 dBm from a continuous wave signal generator
connected to the receiver input terminals,

3. On the bands above 30 MHz this available power shall be -93 dBm,

4. The metering system shall be based on quasi-peak detection with an
attack time of 10 msec ∀ 2 msec and a decay time constant of at least
500 msec.
