Standard parameters for Boneh–Lynn–Shacham signature?

The Boneh–Lynn–Shacham signature is (as far as I know) unrivaled in compactness, promising $b$-bit security for $2b$-bit signature.

Are there standard parameters for BLS signature, (being?) defined by standard bodies, security authorities, or other recognized authority; or otherwise common?

In particular, is there something in the upcoming ISO/IEC 15946-5 Information technology - Security techniques - Cryptographic techniques based on elliptic curves - Part 5: Elliptic curve generation?

The best implementation that I know of for these things is BN448 that was presented at RealWorldCrypto 2018. The constants in their constants.go must have come from somewhere - not necessarily a standards body, but Brendan is a well-known and competent cryptographer.
• The author of BN448 apparently introduced it so that it "should be closer to the 128-bit security level". How far are we from $b$-bit security for $2b$-bit signature? – fgrieu Apr 27 '18 at 1:22
• It seems that originally BN256 was intended to offer 128-bit security, realising the $2b$ signatures, but then new attacks were found. The relevant link has an extra "." on the end causing an error, remove the final period and it works again. Or see a thread view of the discussion. – Bristol Apr 27 '18 at 6:36
