APPENDIX D TO PART 27 - HIRF ENVIRONMENTS AND EQUIPMENT HIRF TEST LEVELS This appendix specifies the HIRF environments and equipment HIRF test levels for electrical and electronic systems under Section 27.1317. The field strength values for the HIRF environments and laboratory equipment HIRF test levels are expressed in rootmean-square units measured during the peak of the modulation cycle. (a) HIRF environment I is specified in the following table: TABLE I. - HIRF ENVIRONMENT I Frequency Field strength (volts/meter) Peak 10 kHz-2 MHz ................................... 2 MHz-30 MHz ................................. 30 MHz-100 MHz ............................. 100 MHz-400 MHz ........................... 400 MHz-700 MHz ........................... 700 MHz-1 GHz ................................ 1 GHz-2 GHz .................................... 2 GHz-6 GHz .................................... 6 GHz-8 GHz .................................... 8 GHz-12 GHz .................................. 12 GHz-18 GHz ................................ 18 GHz-40 GHz ................................ 50 100 50 100 700 700 2,000 3,000 1,000 3,000 2,000 600 (b) HIRF environment II is specified in the following table: TABLE II. - HIRF ENVIRONMENT II Frequency Field strength (volts/meter) Peak 10 kHz-500 kHz ................................ 500 kHz-2 MHz ................................. 2 MHz-30 MHz ................................. 30 MHz-100 MHz ............................. 100 MHz-200 MHz ........................... 200 MHz-400 MHz ........................... 400 MHz-1 GHz ................................ 1 GHz-2 GHz .................................... 2 GHz-4 GHz .................................... 4 GHz-6 GHz .................................... 6 GHz-8 GHz .................................... 8 GHz-12 GHz .................................. 12 GHz-18 GHz ................................ 18 GHz-40 GHz ................................ 20 30 100 10 30 10 700 1,300 3,000 3,000 400 1,230 730 600 Jkt 247046 PO 00000 Frm 00580 Fmt 8010 Average 20 30 100 10 10 10 40 160 120 160 170 230 190 150 In this table, the higher field strength applies at the frequency band edges.
