Inspection and Certification11.1 Inspection by the purchaser prior to shipment shall be specified in the purchase order.11.2 The manufacturer
45、 shall afford the inspector, without charge, all reasonable facilities to satisfy him that the fittings are beingfurnished in accordance with this specification. Any tests (except product analysis) and inspection agreed upon and so stated inthe purchase order shall be made at the place of manufactur

49、ize shall be stamped (Note 4), stenciled,electroetched, or otherwise suitably marked on each fitting. In addition, each fitting shall be marked with the identification symboland suffix for the respective specification listed in Table 1. On wall thicknesses thinner than Schedule 40S, no stamps or otherindented markings shall be used. When the size does not permit complete marking, identification marks may be omitted in thesequence shown in MSS SP-25.NOTE 4When steel stamps are used, they should be applied prior to heat treatment a
