STATEMENT OF WORK

MACHINING AND HEAT TREATING OF CHARPY SPECIMENS

PART 1

GENERAL INFORMATION

1. GENERAL INFORMATION

1.1. Summary: The purpose of this procurement is to identify machine shops and producers capable of machining and supplying Charpy Specimens according to the National Institute of Standards and Technology (NIST) specifications. All participating vendors must be pre-certified and placed on the Qualified Manufacturers List (QML).

1.1.1.Charpy Specimens are pieces of steel that have a specific hardness due to heat treatment and exacting machining requirements. NIST has manufacturers produce Charpy Specimens in batches. The process has three major steps:

1.1.1.1.Rough machining, where the steel bar is cut to length and machined into blanks. The blanks are not notched and have oversized dimensions suitable for heat treating. Blanking eliminates surface defects that can induce quench cracks during processing, and the oversized dimensions of the blanks allow for re-processing when necessary.

1.1.1.2.Heat treating the blanks, so that the final machined specimens meet the NIST acceptance criteria specified in Part 5.

1.1.1.3.Final machining of heat-treated specimens to final dimensions, as indicated in Part

1.2.Background: The NIST Standard Reference Materials (SRM) Program provides SRM 2092, SRM 2093, and SRM 2113 (Low-Energy Charpy Specimens), SRM 2096, SRM 2097, and SRM 2112 (High-Energy Charpy Specimens), and SRM 2098 (Super-High-Energy Charpy Specimens) to industry to indirectly verify Charpy impact testing machines in accordance with ASTM E23 and ISO 148-2 standards. NIST Charpy SRMs are required in various industry standards and specifications to verify the performance of industrial impact machines to ensure a common measurement base for purposes of trade and commerce. All measurements made by the United States and international industry under the American Society for Testing and Materials (ASTM) E23 test standard are traceable to NIST through these SRMs. The Charpy Specimens are the highest-demand SRMs distributed by NIST.

Rev 1.0 June 23, 2021 2

1.3.To produce Charpy specimens, steel blanks are heat treated in a batch. The entire heat-treated batch, which is typically around 1900 specimens, is designated as the production lot. A pilot lot of 100 specimens, drawn at random from this production lot, is selected for acceptance testing, as discussed herein.

1.4.Period of Performance: The period of performance shall be for one Base Year of 12 months and four 12-month option years. See Commercial Acquisition Regulation (CAR) clause 1352.270-70, Period of Performance for actual dates.

The COR is authorized to perform the following functions: maintain written and oral communications with the Contractor concerning technical aspects of the contract, monitor Contractor's performance and notify the Contracting Officer of any deficiencies. A letter of designation issued to the COR, a copy of which is sent to the Contractor, states the responsibilities and limitations of the COR, especially with regard to changes in cost or price, estimates, or changes in delivery dates. The COR is not authorized to change any of the terms and conditions of the award.

1.10.Technical Point of Contact (TPOC): The TPOC will be identified by name upon contract award. The TPOC is the technical program manager and is responsible for ensuring the final product meets the contractual, technical requirements. The TPOC will notify the Contractor and the COR of any deficiencies. The TPOC will work with the Contractor to address product deficiencies. The TPOC will coordinate the availability and shipment of GFM. For this award, the Charpy Coordinator is the

TPOC.

Rev 1.0 June 23, 2021 3

ACCEPTANCE TESTING PROCEDURES

6. ACCEPTANCE TESTING PROCEDURES

6.1.For SRMs 2092/2093/2113 (Low-Energy Specimens) and SRMs 2096/2097/2112 (High-Energy Specimens), the microstructure shall be 100 % tempered martensite. No ferritic, austenitic, or bainitic structures shall be visible when polished sections are examined at 1000X.

6.2.For all specimens, all dimensions shall be within the stated tolerances.

6.3.For each measured specimen, hardness readings taken at opposite ends of the specimen shall not differ by more than 1.5 HRC (Rockwell C Hardness). The hardness value of each specimen will be the average of the two measurements taken at opposite ends. The coefficient of variation of all measured hardness values (ratio between standard deviation and average value) shall not exceed 2 %.

If either, or both, these hardness requirements are not fulfilled, the Charpy Coordinator will determine whether the lot shall be rejected before testing the specimens.

Rev 1.0 June 23, 2021 10

6.4.The average hardness of low-energy specimens shall not be less than HRC 44.

6.5.The recommended ranges for the average absorbed energies of Charpy specimens are as follows:

6.5.1.Low-energy specimens: between 13.0 J and 20.0 J (9.5 ft.-lbf to 15.0 ft.-lbf).

6.5.2.High-energy specimens: between 85.0 J and 140.0 J (63.0 ft.-lbf to 103.0 ft.-lbf).

6.5.3.Super-high-energy specimens: between 175.0 J and 240.0 J (129.0 ft.-lbf to

177.0 ft.-lbf).

6.6.The Charpy Coordinator will determine if lots outside of the recommended ranges can be accepted.

6.7.Specimens at all energy levels shall meet the following requirements.

6.7.1.1.The sample size (nSS) is calculated as follows:

𝑛𝑛𝑆𝑆𝑆𝑆 = �

3𝑆𝑆𝑝𝑝

𝐸𝐸

where E is equal to the greater of 1.4 J or 5 % of the average energy for the 3 machines, and Sp is the pooled standard deviation of the 3 reference machines.

The standard deviation (s) and the pooled standard deviation (Sp) are calculated as follows:

𝑆𝑆𝑝𝑝 = �𝑠𝑠1

2 + 𝑠𝑠22 + 𝑠𝑠32 𝑠𝑠𝑖𝑖 = �(𝑥𝑥1 − 𝑥𝑥)2 + (𝑥𝑥2 − 𝑥𝑥)2+. . . +(𝑥𝑥𝑛𝑛 − 𝑥𝑥)2 𝑛𝑛 − 1 where sl, s2, and s3 are the standard deviations of the three reference machines.

The sample size, nSS, shall not exceed 5.0. Only for super-high energy specimens, if the sample size, nSS, is between 5.0 and 7.0, the Charpy Coordinator will determine whether the lot can be accepted.

6.7.1.2.The number of outliers shall not exceed 10 % of the number of specimens tested (4 is the maximum when 75 specimens are tested). The outlier analysis is performed using box-and-whiskers plots. Outliers are defined as values that are lower than the first quartile or higher than the third quartile by more than 1.5 times the absolute difference between the first and third quartiles. An alternative outlier analysis can be performed by means of Grubbs’ test (extreme studentized deviate) with α = 0.05. An

Rev 1.0 June 23, 2021 11 outlier will not be removed from analysis unless it shows physical evidence of jamming, material flaws, or other reason for atypical behavior.

6.8.If the specimens from a pilot lot fail to meet any of the above requirements, the

Contractor will be asked to provide an additional pilot lot, unless three pilot lots have already been furnished.

6.9.If the specimens from a production lot fail to meet the above requirements, the Charpy Coordinator will determine if it is in the Government’s best interest to have the Contractor take corrective action with regards to resubmission of failed production lots.

PART 7

See (Section 6) above for acceptance testing procedures. If the pilot lot fails to meet the specifications in this contract, the Charpy Coordinator will reject it and may suggest re-heat treatment of the batch based on the test outcome. If new steel is to be used, it will be provided to the Contractor by the Charpy Coordinator. The remaining specimens from the failed lot are to be returned to NIST at the Contractor's expense. NIST will destroy returned specimens. No more than three attempts at producing a successful pilot lot will be permitted.

8.1.1.Sampling plan for NIST pilot lots

8.1.1.1.Each pilot lot shall consist of 100 specimens.

Rev 1.0 June 23, 2021 13

8.1.1.2.If more than one basket is used during heat treating, an equivalent amount of specimens from each basket shall be provided in the pilot lot.

8.1.1.3.Specimens from predetermined locations to sample every position in the basket(s) shall be provided in cooperation with the Charpy Coordinator.

8.1.1.4.The Contractor shall provide a list of specimens (serial numbers) taken from each basket's location to the Charpy Coordinator. The relative position of each specimen in the basket (top, middle, bottom, etc.) in the furnace shall be clearly identified.

PART 9

PRODUCTION SPECIMEN TESTING AND ACCEPTANCE

9. PRODUCTION SPECIMEN TESTING AND ACCEPTANCE

9.1.Specimens shall be randomly drawn from the production lot by the Charpy Coordinator and tested. If the production lot specimens fail to meet the requirements (Section 6), the Charpy Coordinator will reject the lot unless the Charpy Coordinator determines that the Contractor can implement corrective actions. Production lots that fail because of microstructure (Section 6.1.), hardness (Section 6.3.), and/or sample size (Section 6.7.) will be rejected, and the Contractor will be compensated at 30 % of the production lot value. Production lot failure caused by unacceptable specimen dimensions and tolerances (Section 6.2.) will not be compensated. The Charpy Coordinator will determine if it is in the Government’s best interest to have the Contractor take corrective action regarding resubmission of failed production lots. NIST will destroy all specimens from failed lots, and the lot number will be recorded as invalid for SRM purposes.

PART 10

DEFECTIVE GOVERNMENT MATERIAL

10. DEFECTIVE GOVERNMENT-FURNISHED MATERIAL (GFM)

10.1.If the Government determines that pilot or production lot failure is due to defective GFM, the Contractor shall be compensated at 30 % of the entire lot value (pilot + production) as a lot processing fee. Further, the Contractor will be compensated $25.00/specimen for each fully machined specimen produced at the time of Government notification to the Contractor about the defective GFM.

Rev 1.0 June 23, 2021 14

“Fully machined specimens” includes all specimens already delivered to NIST for acceptance testing for that lot, for example, multiple pilot lots of 100 specimens each. Fully machined specimens that have not yet been delivered to NIST (for example, pilot lot specimens in preparation) must have been authorized for production by NIST.

10.2. The CO and/or COR must approve in writing the production of any and all production lots. NIST will not provide consideration for any production lot specimens produced prior to written pilot lot acceptance and approval and CO and/or COR written authorization for the production of production lot specimens.

10.3.The exact number as of the date of Government notification must be documented by the Contractor to the Charpy Coordinator promptly. Maximum compensation will be capped at the entire lot value.

INVOICE DEDUCTIONS FOR LATE DELIVERIES

13. INVOICE DEDUCTIONS FOR LATE DELIVERIES

13.1. The delivery time allotted for each lot (pilot and production) on a DO is designated above in Section 12, Figures 4 and 5, as commensurate with FAR 52.212-4 (a) Inspection and Acceptance. The Contractor shall resolve the deficiencies as documented by the COR/TPOC in the failed inspection report. The COR/TPOC will perform a re-inspection and further assess the area of concern once again on a pass/fail basis. If the area of concern still does not meet the contractual standards, an invoice deduction will be assessed. FAR 52.212-4 (s) Order of precedence applies.

13.2. A late notice will be issued to the Contractor when a scheduled delivery date on a

DO as prescribed above in Section 12, Figures 4 and 5 for each lot (pilot and/or production) fail to meet the terms and conditions described in this SOW. The deduction amount to be assessed against the invoice and will be short-paid.

13.3. A deduction of 1 % of the entire lot price (pilot and/or production) per full week of late delivery for any of the dynamic schedule delivery dates. Deductions are cumulative across the delivery dates for a particular lot, with a cap of 5 % of the entire lot price as the maximum deduction that can be levied. Thus, there is a grace period up to one week before the first or next deduction is levied. A two-day delivery would not incur a deduction. In contrast, a delivery that is 11 days late would incur a 1 % deduction, and one that is 15 days late would incur a 2 % deduction.
