1 ASTM International Proficiency Test Programs and Interlaboratory Studies Program Presenters: David Bradley and Phillip Godorov September 2006

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 identical samples are sent to participating labs where they are analyzed using standard test methods and results reported for statistical treatment September 2006

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 2006

4 ASTM Proficiency Testing Programs September 2006 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 2,500 laboratories participating Over 40% participation outside continental U. S. September 2006


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 Plastics: Mechanical Properties Testing Polypropylene Mechanical Properties Testing Flammability Plastics Testing Textiles (Light, Medium, and Heavy Duty Woven Fabric): (D13) ASTM PROGRAMS September 2006

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. Contact Robin Haupt at for additional information or visit the CCRL web site on ASTM web page. ASTM PROGRAMS September 2006

11 Petroleum Products and Lubricants (D02) Engine Oil Lubricants #2 Diesel Fuel Aviation Turbine (Jet A) Fuel Motor Gasoline #6 Fuel Oil Automatic Transmission Fluid Gear Oil Reformulated Gasoline Lube Additives Industrial Gear Oil Turbine Oil Lubricating Grease Crude Oil In-Service Diesel Oil Base Oils Wax General Gas Oils Low Sulfur Diesel ASTM PROGRAMS September 2006

12 Provides labs with SQC tool to compare individual 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 2006 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 2006

14 Establishing New Programs Concept approved by Executive Subcommittee Program pre-proposal Market study Final program proposal ASTM staff can provide guidelines and assistance. September 2006

15 The programs are open to all labs. September 2006

17 Interlaboratory Studies Program (ILS) September 2006

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 September 2006

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 September 2006

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 September 2006

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 Help meet the interlaboratory testing requirements of many accreditation programs u Recognition in the final Research Report September 2006

22 Use of Programs by ASTM Committees u Obtain valuable feedback on methods, leading to the correction of errors and omissions, as well as highlighting the need for technical updates u Resource for increased membership u Database of laboratories for test method validation u Database of suppliers for common study materials September 2006

23 Establishing New Programs u Concept approved by Executive Subcommittee u Program registered online u Initial conference call with the a technical contact from the committee, to establish the basic study parameters u Experimental design (with input from the committees statistical support person, if available) u Identification of study materials, suppliers, a distributor, and volunteer laboratories September 2006



26 Administering Programs u Virtual Meetings with the participants to discuss specific study instructions u Coordination of acquisition and distribution of study material u Physical u Electronic u Collection of data u Analysis of data u Compilation of Precision Statement and Draft Research Report (from registered information) September 2006
