Emicode EC1plus with testing standard ISO 16000

Our experience has been that any certificate submitted needs to cite the reference standards used for that particular Credit, in order to be accepted. If your product was tested according to a different reference standard, you could try submitting it, with the description of the test itself, and how it is similar (or different).
Generally, we have found that the v4 and v4.1 reviews have been very strict on projects submitting the correct certifications.

When submitting materials with one of the certificates included in this table https://www.usgbc.org/resources/low-emitting-materials-third-party-certification-table, we have never provided additional documentation addressing the particular testing standard as, per our interpretation, is implied (and so far the reviewers have accepted them). For materials with test reports that make a comparison with the requirements of a certain certification level (e.g. EC1plus, M1,...), without the actual certification, the reference to a standard is required to prove that such a comparison is indeed possible and that the material would presumably achieve that level if submitted for certification.
