a. Are there any rules on the specifications?
Standards and technical specifications in applicable procurement documents shall promote the broadest possible competition, while ensuring performance or other requirements for the procurement. To the extent possible, in international competitive procurement, the borrower shall specify internationally accepted standards with which the equipment, materials or workmanship shall comply. When such international standards do not exist or are inappropriate, national standards may be specified. In all cases, the procurement documents shall state that equipment, material, or workmanship meeting other standards that are at least substantially equivalent to the specified standards will also be accepted.
