3 XRF Analysis The instrument used for this Lead Paint Inspection was an X-ray fluorescence unit (XRF) manufactured by the Heuresis Corporation serial number HOW TO INTERPRET XRF READINGS: There are fourteen columns in the XRF table. The interpretation of each column is as follows: Column 1 Reading Number (#): This is the reading number on the instrument. Column 2 Units: The way the instrument correlates the data. Most often mg/cm 2 Column 3 Results: The result of the assay Column 4 Date/Time: This is the time and date the reading was taken. Column 5 User: The certificate number of the inspector performing the lead test. Column 6 Job: The physical address of the job site. Column 7 Location: Interior, Exterior, or Calibration. This column simply states if the assay was take on the interior or the exterior of the site. Additionally, this column can list Calibration. The XRF must be calibrated before inspection and at the end of the inspection. The XRF also needs to be calibrated every 4 hours if the inspection time exceeds 4 hours. Column 8 Room: This column identifies the room where assay was taken. This column may be represented by a - - if the reading was taken on the exterior of a building and the room was unspecified. Column 9 Component: This column identifies the surface that was tested. Some examples are door, door trim, wall, ceiling, window, etc. Retain these records for a minimum of 3 years or as required by law. Lead Safe Testing, LLC E. Girard Ave. Building A, Suite 412 Denver, CO Page 3

4 Column 10 Description: This column identifies an associated part of the components, e.g. sash to describe the sash of a window. This column may be represented by an -- if the reading was taken on a specific component, e.g. a wall will not have an associated part. Column 11 Substrate: This column defines what material the paint was applied to. Substrates are most commonly plaster, drywall or wood but could be other material such as metal, vinyl, or stucco. Column 12 Side: This column determines where the component being tested is located in the room. Side A is usually the street side of the building. Then, going in a clockwise direction, the adjacent sides are labeled B, C and D. Sides A, B, C and D are identified on the Floor Plan where applicable. For example, if you were standing in a bedroom that had two windows on different walls these windows would be identified by the side location such as Window Side A and Window Side B. Column 13 Floor: This simply corresponds to the floor of the building. Column 14 Condition: This column identifies the condition of the paint on the surface being tested. The terms intact, poor, peeling, chalking, cracking are used to describe the paint condition for HUD funded projects. Retain these records for a minimum of 3 years or as required by law.

5 EFFECTIVE DATE: December 1, 2015 MANUFACTURER AND MODEL: Performance Characteristic Sheet Make: Models: Source: Heuresis Model Pb200i 57 Co, 5 mci (nominal new source) FIELD OPERATION GUIDANCE OPERATING PARAMETERS: Action Level mode XRF CALIBRATION CHECK LIMITS: 0.8 to 1.2 mg/cm 2 (inclusive) SUBSTRATE CORRECTION: Not applicable INCONCLUSIVE RANGE OR THRESHOLD: ACTION LEVEL MODE READING DESCRIPTION Results not corrected for substrate bias on any substrate SUBSTRATE THRESHOLD (mg/cm 2 ) Brick 1.0 Concrete 1.0 Drywall 1.0 Metal 1.0 Plaster 1.0 Wood 1.0 BACKGROUND INFORMATION EVALUATION DATA SOURCE AND DATE: This sheet is supplemental information to be used in conjunction with Chapter 7 of the HUD Guidelines for the Evaluation and Control of Lead-Based Paint Hazards in Housing ("HUD Guidelines"). Performance parameters shown on this sheet are calculated using test results on building components in the HUD archive. Testing was conducted on 146 test samples in November 2015, with two separate instruments running software version in Action Level test mode. The actual source strength of each instrument on the day of testing was approximately 2.0 mci; source ages were approximately one year. OPERATING PARAMETERS

6 Performance parameters shown in this sheet are applicable only when properly operating the instrument using the manufacturer's instructions and procedures described in Chapter 7 of the HUD Guidelines. XRF CALIBRATION CHECK: The calibration of the XRF instrument should be checked using the paint film nearest 1.0 mg/cm 2 in the NIST Standard Reference Material (SRM) used (e.g., for NIST SRM 2579, use the 1.02 mg/cm 2 film). If the average (rounded to 1 decimal place) of three readings is outside the acceptable calibration check range, follow the manufacturer's instructions to bring the instrument into control before XRF testing proceeds. SUBSTRATE CORRECTION VALUE COMPUTATION: Chapter 7 of the HUD Guidelines provides guidance on correcting XRF results for substrate bias. Supplemental guidance for using the paint film nearest 1.0 mg/cm 2 for substrate correction is provided: XRF results are corrected for substrate bias by subtracting from each XRF result a correction value determined separately in each house for single-family housing or in each development for multifamily housing, for each substrate. The correction value is an average of XRF readings taken over the NIST SRM paint film nearest to 1.0 mg/cm 2 at test locations that have been scraped bare of their paint covering. Compute the correction values as follows: Using the same XRF instrument, take three readings on a bare substrate area covered with the NIST SRM paint film nearest 1 mg/cm 2. Repeat this procedure by taking three more readings on a second bare substrate area of the same substrate covered with the NIST SRM. Compute the correction value for each substrate type where XRF readings indicate substrate correction is needed by computing the average of all six readings as shown below. For each substrate type (the 1.02 mg/cm 2 NIST SRM is shown in this example; use the actual lead loading of the NIST SRM used for substrate correction): Correction value = (1st + 2nd + 3rd + 4th + 5th + 6th Reading)/ mg/cm 2 Repeat this procedure for each substrate requiring substrate correction in the house or housing development. EVALUATING THE QUALITY OF XRF TESTING: Randomly select ten testing combinations for retesting from each house or from two randomly selected units in multifamily housing. Conduct XRF re-testing at the ten testing combinations selected for retesting. Determine if the XRF testing in the units or house passed or failed the test by applying the steps below. Compute the Retest Tolerance Limit by the following steps: Determine XRF results for the original and retest XRF readings. Do not correct the original or retest results for substrate bias. In single-family and multi-family housing, a result is defined as a single reading. Therefore, there will be ten original and ten retest XRF results for each house or for the two selected units. Calculate the average of the original XRF result and the retest XRF result for each testing combination. Square the average for each testing combination. Add the ten squared averages together. Call this quantity C. Multiply the number C by Call this quantity D. Add the number to D. Call this quantity E.

7 Take the square root of E. Call this quantity F. Multiply F by The result is the Retest Tolerance Limit. Compute the average of all ten original XRF readings. Compute the average of all ten re-test XRF readings. Find the absolute difference of the two averages. If the difference is less than the Retest Tolerance Limit, the inspection has passed the retest. If the difference of the overall averages equals or exceeds the Retest Tolerance Limit, this procedure should be repeated with ten new testing combinations. If the difference of the overall averages is equal to or greater than the Retest Tolerance Limit a second time, then the inspection should be considered deficient. Use of this procedure is estimated to produce a spurious result approximately 1% of the time. That is, results of this procedure will call for further examination when no examination is warranted in approximately 1 out of 100 dwelling units tested. TESTING TIMES: In the Action Level paint test mode, the instrument takes the longest time to complete readings close to the Federal standard of 1.0 mg/cm 2. The table below shows the mean and standard deviation of actual reading times by reading level for paint samples during the November 2015 archive testing. The tested instruments reported readings to one decimal place. No significant differences in reading times by substrate were observed. These times apply only to instruments with the same source strength as those tested (2.0 mci). Instruments with stronger sources will have shorter reading times and those with weaker sources, longer reading times, than those in the table. Mean and Standard Deviation of Reading Times in Action Level Mode by Reading Level Reading (mg/cm 2 ) Mean Reading Time (seconds) Standard Deviation (seconds) < > CLASSIFICATION OF RESULTS: XRF results are classified as positive if they are greater than or equal to the stated threshold for the instrument (1.0 mg/cm 2 ), and negative if they are less than the threshold. DOCUMENTATION: A report titled Methodology for XRF Performance Characteristic Sheets (EPA 747-R ) provides an explanation of the statistical methodology used to construct the data in the sheets, and provides empirical results from using the recommended inconclusive ranges or thresholds for specific XRF instruments. The report may be downloaded at This XRF Performance Characteristic Sheet (PCS) was developed by QuanTech, Inc., under a contract with the XRF manufacturer.
