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.
Receiving Q/A Authority – The person or department designated by the Owner responsible for assuring quality of incoming commodity material.
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).
Vendor – Recipient of a direct purchase order.

PROCEDURE

Pipe CMTR’s, when required by Purpose Order, shall be reviewed for conformance with chemical and physical requirements.
A inspection lot of each received lot shall be inspected as follows:
Pipe shall be visually examined to ensure that the Manufacturer’s heat number and pipe or tubing specification (grade) markings are legible on each length inspected, and color coding identification is correctly applied.
Pipe shall be verified to conform with dimensional requirements of the applicable pipe specification.
The inside diameter of the inspection lot shall be visually examined for evidence of manufacturing defects and for surface condition.
The outside surface of the inspection lot shall be examined for surface condition, including coating condition, if applicable.
If the pipe lengths have been specified to be prepared for welding, they shall have end finish examined and shall have bevel dimensions checked for conformance with applicable specifications.
Alloy pipe and tube shall be PMI checked per the requirements of EP 15–1–4.

5.0 DOCUMENTATION

Inspection of each lot of pipe or tubing 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.Table 1
