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

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.

ASTM Proficiency Testing Programs
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.

ASTM's Cement and Concrete Reference Laboratory (CCRL)
ASTM Committees mortar.
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 Contact Robin Haupt at 301-975-6704 for additional information or visit the CCRL web site on ASTM web page.

ASTM Proficiency Testing Programs
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
Use of Programs by ASTM Committees
Obtain valuable feedback on methods Resource for increased membership Database of laboratories for test method validation September 2006
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
The programs are open to all labs.

Interlaboratory Studies Program (ILS)
September 2006
ASTM ILS Program
Objectives
Strengthen the perceived quality of ASTM Test Methods Produce data that will be used to develop Precision & Bias statements and Research Reports Provide administrative support to the committees Provide financial support to the committees Help ensure the confidentiality of participating labs September 2006
Administrative Support
Review of Experimental Design Assistance identifying volunteer laboratories Identification of sample vendors Coordination of sample distribution Data collection Statistical processing Generation of reports September 2006
Strengths of the ASTM Interlaboratory Study Program
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 Scientific neutrality of ASTM in reviewing test data Provides value-added Quality Assurance Programs to participating laboratories September 2006
Potential Benefits of Participation
Statistical program to monitor strengths and weaknesses of lab testing when compared to peers Assess testing performance and adherence to written procedures by lab technicians Help meet the interlaboratory testing requirements of many accreditation programs Recognition in the final Research Report September 2006
Use of Programs by ASTM Committees
Obtain valuable feedback on methods, leading to the correction of errors and omissions, as well as highlighting the need for technical updates Resource for increased membership Database of laboratories for test method validation Database of suppliers for common study materials September 2006
Establishing New Programs
Concept approved by Executive Subcommittee Program registered online Initial conference call with the a technical contact from the committee, to establish the basic study parameters Experimental design (with input from the committee’s statistical support person, if available) Identification of study materials, suppliers, a distributor, and volunteer laboratories September 2006
