ASTM E1528 — Transaction screen
An ASTM practice describing a limited environmental due-diligence transaction-screen process.
Standards references reviewed September 15, 2026. These summaries explain purpose, not the full standard. Confirm the edition required by your contract, program, and jurisdiction; publication of a newer edition does not automatically change local requirements.
Why it matters
It is not interchangeable with a Phase I ESA and is not intended to satisfy All Appropriate Inquiries. Choose the scope around the transaction’s requirements rather than assuming a shorter report gives equivalent protection.
In practice
A project example
A lender’s acceptance of a limited screen does not establish that it satisfies a purchaser’s separate environmental inquiry needs.
