Physical Requirements Physical Requirements5.1 At the time of delivery to the site of the work, the unitsshall conform
14、 to the requirements prescribed in Table 1.6. Dimensions and Permissible Variations6.1 The thickness of any unit shall be not less than 5 in. (127mm).6.2 Overall dimensions shall not vary by more than 6 3%from the specified dimensions.7. Sampling and Testing7.1 The purchaser or his authorized repres
15、entative shall beaccorded proper facilities to inspect and sample the units at theplace of manufacture from the lots ready for delivery.7.2 Units shall be sampled and tested in accordance withTest Methods C140.7.3 Except as specified in Section 8, and unless otherwiseagreed, the expense of inspectio
16、n and testing shall be borne bythe purchaser.8. Visual Inspection8.1 All units shall be 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 rem
17、ove unitsfrom the shipment. A new sample shall be selected by thepurchaser from remaining 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-
18、sented by the sample meets the specified requirements. If thesecond sample fails to meet 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 typi
19、cally borne as follows: (1) if the results of the tests show thatthe units do not conform 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 t
