September 2006

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

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 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 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 301-975-6704 for additional information or visit the CCRL web site on ASTM web page.

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
