PPROBLEMA CONVERSÃO DE DOCUMENTO EM PADRÃO PDF A

contudo segundo  pesquisas realizadas a frase correta que deveria apresentar seria : Este arquivo está em conformidade com o  padrão PDF/A e foi aberto no modo somente leitura para impedir modificações. 

No, actually that would be wrong.

The phrase in the English Acrobat UI describes the situation correctly:

The reason is that here Acrobat only looks at the document metadata which for a PDF/A must include a claim that the document in question is a PDF/A. But Acrobat here does not execute a full check whether the document is following all the PDF/A requirements. It, therefore, cannot say that the document actually is compliant, merely that it claims compliance.

Thus, an "está em conformidade" here would imply too much. 

Admittedly, though, "requer conformidade" seems to be a misleading translation of "claims compliance". Here the internationalization of the Acrobat UI should be improved.

Minha dúvida seria o que significa essa frase apresentada no documento gerado ? Caso de fato não seja a frase que deve ser apresentada , como fazer a configuração correta, para que o documento seja convertido no padrão PDF/A?

For the time being you could switch the language of your Acrobat UI to get a more appropriate expression there.
