If ASTM wants to write a standard for HIs, why reinvent the wheel? What is wrong with current versions of IRC and NEC. Seems we already have a national standard and just refuse to recognize that fact.

Before some of you begin to howl and moan about how current IRC/NEC should not be used to assess existing homes, let's look at it more closely. Model codes are minimum standards designed to protect life, limb, and property. Why is that so different from what HIs are doing now?
