The DTI-BPS will accept technical views/comments for the said draft PNS not later than 27 March 2020. Copies of the said standards are available upon request at the Standards Development Division. Suggestions requiring revision and modifications on the text should indicate the preferred wordings and the relevant clause number should be quoted against any comment.

The BPS will consolidate and process all comments to finalize the DPNS and have it approved for promulgation.

The DTI-BPS is the National Standards Body of the Philippines. It is the Philippines’ member to the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC).
