16、e sound and free of cracks or otherdefects that interfere with the proper placing of the unit.9. Compliance9.1 If a sample fails to conform to the specified require-ments, the manufacturer shall be permitted to remove unitsfrom the shipment. A new sample shall be selected by thepurchaser from remain

17、ing units from the shipment with asimilar configuration and dimension and tested at the expenseof the manufacturer. If the second sample meets the specifiedrequirements, the remaining portion of the shipment repre-sented by the sample meets the specified requirements. If thesecond sample fails to me

18、et the specified requirements, theremaining portion of the shipment represented by the samplefails to meet the specified requirements.NOTE 1Unless otherwise specified in the purchase order, the cost oftests is typically borne as follows: (1) if the results of the tests show thatthe units do not conf

19、orm to the requirements of this specification, the costis typically borne by the seller; (2) if the results of the tests show that theunits conform to the specification requirements, the cost is typically borneby the purchaser.10.
