Are you using the 2013 edition of IEC 61000-4-6? It's certainly a bit confusing. Figure 5 shows the strap without any qualification about its use, but Figure 14 says 'if needed'.

From: David [mailto:000000fdec74198b-dmarc-requ...@ieee.org] Sent: Thursday, November 10, 2016 12:14 AM To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: [PSES] Bulk Current Injection All, I’m trying to learn more about Bulk current injection. I’ve read Javor’s Field to Wire Coupling papers, as well as -4-6, ISO 11452-4, SAE J1113-4, and CS114. I’m primarily interested in grounding, and the differences between -4-6 and the rest. -4-6 requires that the injection probe or clamp is grounded with a short ground strap. MIL STD, ISO, and SAE don’t do so. I would assume it’s due to the difference between a test simulating commercial AC powered equipment versus vehicle mounted equipment. I’d like a more thorough understanding of why. Also, if I do not ground the BCI probe during -4-6, say during an in situ test on an elevated cable, what would the result be? An under test, over test, or unknown? For large equipment would it make sense to tie it to the chassis?
