QUALITY STANDARD FOR POSITIVE MATERIAL IDENTIFICATION OF VALVES, FLANGES, FITTINGS, AND OTHER PIPING COMPONENTS 1.

SCOPE 1 .1 This Standard Practice provides methods and acceptance standards for Positive Material Identification (PMI) of metal flanges, fittings, valves, pressure boundary parts of valves, and other piping components.

Since the intensity of the light is proportional to the quantity of the element in the material, the concentration of the element can be measured and the material identified.

X-Ray Fluorescence

2.4 A method of positive material identification that detects the energy strength level of X-rays being emitted from the material. Each element in the material emits a different X-ray energy strength level. These different X-ray strength levels are measured and compared to the known energy levels for each element in the material. The instrumentation makes an analysis of the different X-ray energy levels and identifies each alloy in the material being tested as well as the percent concentration of each element in the material. This identification of the various elements can then be compared to a known standard and the particular grade of material identified.

1 .2 The instrumentation used for PMI testing covered by this Standard Practice shall be optical spectroscopy or X-ray fluorescence. 1 .3 This Standard Practice is applicable to the identification process, at point of final inspection or in-process inspection during manufacturing. 1 .4 The PMI test is for material grade identification only and does not substitute for a manufacturer’s test report or a laboratory’s chemical analysis. 2.

DEFINITIONS

Semi-Quantitative Analysis

2.1 A certified report from the manufacturer showing the chemical composition, mechanical properties, heat treatment, and testing required on the material for compliance with the requirements of the purchase order or the applicable industry standard that governs the material, or both.

Material Test Report (MTR)

2.5 A term used to describe the method of positive material identification. This term is used to point out the fact that, while the field use of PMI instrumentation is capable of precision analysis, the measurements are not being carried out under controlled environmental conditions, and therefore, are not certifiable.

2.2 An examination procedure used to verify material grade type and nominal chemistry of the alloying elements.

Positive Material Identification (PMI)

2.6 A material sample that has been certified by a laboratory with instrumentation that is qualified in accordance with ASTM International.

2.3 A method of positive material identification that detects and quantifies the presence of specific elements in a material. It utilizes the fact that each element has a different unique atomic structure that when subjected to the addition of energy, will emit a pattern of light colors or wavelengths along the spectrum. Since no two elements emit the same pattern of spectral lines, they can be differentiated.

Optical Spectroscopy

2.7 These are items being of the same material, size, pressure class, and type.

Reference Standard

Like Items

Assembled Items

2.8 These are items previously assembled that are selected from existing inventory.

Disassembled Items

2.9 These are component parts (manufactured or selected from existing inventory) that have not yet been assembled.

MSS

STANDARD PRACTICE Alloy Material

All parts examined shall be marked with PMI (physical space permitting and non-critical surfaces available) to denote conformance that the part was PMI examined. This PMI marking shall be permanent on the piece and not removed by installation processes such as welding or weld preparation.

2.1 0 A metal that contains alloying elements (e.g. chromium, nickel, or molybdenum) that are intentionally added to enhance mechanical properties or corrosion resistance or both. 3.

SP-1 37

PROCEDURE

PMI

3.1 The identification shall be initiated by ensuring the instrumentation is within detection limits or calibration curves, or both, prior to analysis of the material. This step is completed by checking the unit with certified reference standards.

PMI stamps, when used, shall be low stress. The type of marking will depend on the product form, but shall be permanent, (e.g., PMI must appear on a cast or forged product). A casting that might have chemical etch markings and forging could have a roll marking. PMI examination may be performed in process or in the final inspection stage after manufacturing. The parts shall be identified as being PMI examined after the inspection results have been verified and accepted to the ASTM Number and Grade marked on or identified to the part.

Optical Spectroscopy

3.2 This shall be the method used when the otherwise nonmandatory analysis for Carbon is required, (e.g. to separate an H-grade from L-grade austenitic stainless steel).

X-Ray Fluorescence or Optical Spectroscopy These methods may be used to

3.3

4.

identify the major alloy elements of a material such as those listed in Tables 1 A and 1 B.

MATERIAL VERIFICATION

Acceptance Standards

4.1 The acceptance standards for PMI shall include nominal chemistry verification of the major alloying elements of the material grades listed in Tables 1 A and 1 B, as compared to the ASTM elemental ranges for the specification of the product being examined. The acceptable measure of alloy range shall be as specified in the appropriate ASTM specification(1 ).

Weight Percentage

3.4 The actual chemical elements in weight percentages are not required to be reported if the instrumentation is capable of identifying the grade. Whether the analysis is on element weight percentage or a grade identification match, references in Tables 1A or 1B shall be used for the major alloy component identification of the material. If an alloy is not listed in Table 1A or 1B, the major elements of the material, e.g., Chromium (Cr); Molybdenum (Mo), Nickel (Ni), Titanium (Ti), and Columbium/Niobium (Cb/Nb), shall be the basis for determination of the alloy.

Elemental Percentage Weight

4.2 If an elemental percentage weight is required for examination, ASTM product analysis tolerances would apply for acceptance purposes (e.g., ASTM A960/A960M tolerances would apply for wrought products; ASTM A961 /A961 M would apply for steel flanges, forged fittings, valves, and parts for piping applications; and ASTM A962/A962M would apply for bolting products).

PMI Examination

3.5 Unless otherwise specified by the purchase order, and agreed upon by the purchaser and provider, single component items such as fittings, flanges, or other piping components shall receive 1 00 percent (1 00%) PMI examination. Table 2 provides a sampling plan for valves, which shall be used unless otherwise specified and agreed upon by the purchaser and provider. Table 2 also provides for optional levels of examination for valves when agreed to by the purchaser and provider.

NOTE: (1 ) PMI using Optical Spectroscopy or Xray Fluorescence methods yields a semiquantitative analysis considered to be accurate but not to the same precision of chemical laboratory instruments in a controlled environment.

2

MSS

STANDARD PRACTICE 7.

4.3 Grade Identification This identification is acceptable if the analysis instrumentation is capable of grade identification and the instrumentation is calibrated according to the verification guidelines in Section 3.1 .

NON-CONFORMING PARTS

8.

Parts not meeting the requirements of Section 4 shall be identified as non-conforming parts. Non-conforming parts may be subjected to a laboratory chemical analysis to verify the accuracy of the PMI results (if required). Failure of any inspection sample in an inspection lot rejects all items in the lot until individual testing proves a part acceptable. A failed inspection lot will require 1 00% PMI examination or rejection of the entire lot. 6.

EXAMINER (OPERATOR) QUALIFICATIONS The examiner (operator) of the PMI instrumentation shall be knowledgeable about the PMI operational functions, the PMI test method employed, and also of the alloys being examined. The qualifications of the examiner, including training from the instrumentation manufacturer or training by the component manufacturer, shall be documented and be available at the component manufacturer’s facility.

4.4 Instrument Accuracy Caution is urged when quantifying trace elements present in small concentrations, as they may fall under the instrument’s limit of detection. The acceptance criteria in these instances will be as agreed upon between the provider and end user. 5.

SP-1 37

SAFETY OF INSTRUMENTATION

This Standard Practice does not address safety concerns with either the Optical Spectroscopy or X-ray Fluorescence methods. It is the user’s responsibility to adequately address the safety issues of examination and the proper use of the instrumentation.

DATA REPORTS

Either production records, logs, or check lists shall be acceptable as a mandatory record of examination, confirming that the procedure of PMI has been adequately performed on each part, sub-component part, or assembly; provided they contain the following information: a) PMI Instrument (Manufacturer and Model Number) b) Item Description c) ASTM Material Designation/Identification d) Date of Inspection e) Results: Accepted or Rejected (see Section 5) f) Organization Performing Test g) Operator Performing Test h) Element Percentages (see Tables 1 A and 1 B when required) i) Required By/Purchase Order and Date j) Lot Identification Number
