1 ASTM International Proficiency Test Programs and Interlaboratory Studies Program Presenters: Anne McKlindon and Phillip Godorov September 2010

2 ASTM Proficiency Testing Programs Designed to provide participating laboratories with a statistical quality control tool enabling laboratories to assess their performance in conducting an ASTM test or series of tests. It is a testing program where uniform samples are sent to participating labs where they are analyzed using standard test methods and results reported for statistical treatment September 2008

3 ASTM Proficiency Testing Programs ASTM provides management and administrative support to the program including program registration, contract negotiations, data collection and generation of statistical summary reports ASTM coordinates the preparation and distribution of test samples ASTM provides test data reporting instructions and electronic data report forms for recording data Participation registration fees are assessed to each PTP program. September 2008

4 ASTM Proficiency Testing Programs September 2008 ASTM statistical summary reports include: Listing of all lab data Charts and graphs Lab data coded to maintain lab confidentiality. Final summary reports are provided electronically to participants and appropriate Committee contacts.

7 ASTM Proficiency Testing Programs Globally recognized programs: Over 2,900 laboratories participating Over 50% participation outside continental U. S. September 2008


9 Metals Testing: (E28 and E01) Steel: Mechanical Properties Testing Plain Carbon and Low-Alloy Steel (Chemical Analysis) Stainless Steel (Chemical Analysis) Aluminum (Chemical Analysis) Determination of Gold in Bullion Ores / Metals Environmental Testing Plastics Testing: (D20) Polyethylene Plastics Testing Multiple Plastics: Mechanical Properties Testing Polypropylene Mechanical Properties Testing Flammability Plastics Testing Thermal & Elemental Analyses of Plastics Textiles :(D13) Light, Medium, Heavy Fabric Testing Yarns and Threads ASTM PROGRAMS September 2008

10 Aromatic Hydrocarbons Testing (D16) Engine Coolants Testing (D15) Electrical Insulating Liquids: (D27) Insulating Fluid Quality Dissolved Gas Analyses of In-Service Insulating Fluid ASTM's Cement and Concrete Reference Laboratory (CCRL) ASTM Committees C01 on Cement and C09 on Concrete and Aggregates sponsor the Cement and Concrete Reference Laboratory (CCRL). CCRL is located at the National Institute of Standards and Technology (NIST) as a cooperative program between ASTM and NIST. CCRL operates proficiency sample programs in the following construction materials areas: portland cement, blended cement, masonry cement, hydraulic cement concrete, pozzolans, concrete masonry units, and masonry mortar. Visit the CCRL web site on ASTM web page for more information. ASTM PROGRAMS September 2008

12 Provides labs with a QA tool to compare their performance versus other labs worldwide Provides data for monitoring lab strengths and weaknesses Offers ability to compare results among several test methods measuring the same parameter (e.g., 5 test methods for sulfur) Residual material from these programs along with the published statistical data can provide useful internal QA samples Participation helps satisfy lab accreditation requirements Satisfactory performance can demonstrate testing capability to customers Results and associated statistics helps ASTM validate test method performance under real world conditions September 2008 ASTM Proficiency Testing Programs

13 Use of Programs by ASTM Committees Obtain valuable feedback on methods Resource for increased membership Database of laboratories for test method validation September 2008

14 Establishing New Programs Concept approved by Executive Subcommittee Program pre-proposal Market research Final program proposal Promote & Launch ASTM staff can provide guidelines and assistance. September 2008

15 The programs are open to all companies and industry test professionals. September 2008

17 ASTM International Interlaboratory Study Program (ILS) Presenter: Phillip Godorov August 2010

18 ASTM ILS Program u Strengthen the perceived quality of ASTM Test Methods u Produce data that will be used to develop Precision & Bias statements and Research Reports u Provide administrative support to the committees u Provide financial support to the committees u Help ensure the confidentiality of participating labs Objectives August 2010

19 Administrative Support u Review of Experimental Design u Assistance identifying volunteer laboratories u Identification of sample vendors u Coordination of sample distribution u Data collection u Statistical processing u Generation of reports August 2010

20 Strengths of the ASTM Interlaboratory Study Program u Input encouraged from active Committee volunteers, as well as non-members, broadening the range and diversity of the study participants, allowing the study to most accurately demonstrate expected real-world precision u Scientific neutrality of ASTM in reviewing test data u Provides value-added Quality Assurance Programs to participating laboratories August 2010

21 Potential Benefits of Participation u Statistical program to monitor strengths and weaknesses of lab testing when compared to peers u Assess testing performance and adherence to written procedures by lab technicians u May help meet the interlaboratory testing requirements of accreditation programs u Recognition in the final Research Report and on the Committees webpage August 2010
