STANDARDS AND PUBLICATIONS

DEFINITIONS

Certified Material Test Report (CMTR) – A document, or documents, on which are recorded the results of tests, examinations, repairs, or treatments required by the Material Specification. Supplementary or special requirements, in addition to the requirements of the Material Specification, as required by the Purchase Order shall also be included on the CMTR. The specification of the material being represented including the year of issue, and the material heat number shall also be included on the CMTR. All such documents shall identify the applicable Material Specification and shall be identified to the material represented.
Commodity – Any item of standard design and/or mass manufacture which is purchased in quantity and maintained in stock for routine or specialized Plant use.
Inspection Lot – Unless otherwise specified by the Owner’s Engineer, the inspection lot shall be as follows:

Lot Size	Inspection Lot
5 or less	2
6–20	3
21–40	4
41 and over	10% rounded to the next highest whole number

Manufacturer – The recipient of a direct or indirect purchase order for materials and/or equipment. In this context, a direct order is one issued to a Manufacturer by a Contractor or the Owner. An indirect order is one issued to a Manufacturer by a vendor (recipient of a direct order) for materials, fabricated components, or subassemblies.
Lot – A group of items with the same heat number.
Owner – Inflection Point Engineering, LLC.
Positive Materials Identification (PMI) – A procedure used to insure that alloy materials purchased by or for the Owner are properly identified, and meet the chemical composition of alloy materials as specified in Section II of the ASME Code or an applicable ASTM Specification, and the CMTR.
Receiving Inspection – A receiving inspection shall be that inspection necessary to ensure that the dimensions, physical integrity, chemical composition, and mechanical properties of representative samples of commodity items are in conformance with those detailed by the applicable quality specifications. A receiving inspection shall require performance of specified examinations and tests of an inspection lot of the commodity, and review of documentation and reports that accompany the item(s).
Receiving Q/A Authority – The person or department designated by the Owner responsible for assuring quality of incoming commodity material.
Vendor – Recipient of a direct purchase order.

PROCEDURE

Fastener CMTR’s shall be reviewed for conformance with chemical and physical requirements.
Inspection Lot of each received lot of fasteners shall be inspected as follows:
Fasteners shall be examined to ensure correct marking/stamping of bolt type and Manufacturer.
Alloy fasteners shall be checked to ensure correct alloy content using the Texas Nuclear Portable Alloy Analyzer or similar instrument.
Bolting shall be inspected for condition of threads and to ensure that nuts run onto bolts with little or no resistance.
Bolts shall be examined for adequate lubrication or coating application.

DOCUMENTATION

Inspection of each lot of fasteners shall be documented using the Receiving Inspection Checklist Form Table 1 or an equivalent method that includes all of the elements of the Inspection Checklist.
