A testing laboratory providing these services must be selected with care. In cases where the supervising laboratory technician is supervising technicians who asrm test concrete, the applicable relevant tests are the concrete tests listed in the group.

Specification E provides criteria for the evaluation of agencies that d1077 the inspection of concrete during placement. Ashm instruments enable users astm c1077 both field and laboratory settings to accurately gauge evidence of ferrous wear and use astm c1077 data to support condition-based Where additional calibration or verification requirements have been listed in the Facilities, Equipment, and Supplemental Procedures Section, this information shall also be included in the records.

It is permitted to use a representative sampling to evaluate proficiency of testing personnel. A quarterly exchange of samples between laboratories in accordance with Practice C will provide excellent quality assurance data. C, C, or C, 4 be independent of the participating laboratories, 5 distribute samples astm c1077 least once annually, and astm c1077 maintain a record of all sample test results from participants for at least 3 years.

Other programs may also be available. NOTE 5—Deviation from standard test methods may adversely affect results.

Any one of the following three methods of verification is acceptable. C — 10b Standard Practice for Laboratories Testing Concrete and Concrete Aggregates for Use in Construction and Astm c1077 for Laboratory Evaluation1 This standard is issued under the fixed designation C; the number immediately following the designation indicates c0177 year of atm adoption or, in the case of revision, the year of last revision.

Records concerning the astm c1077, verification, and standardization of equipment are an example.

At the discretion of the inspector, A1. Participation in a proficiency sample program with relative density specific gravity and absorption testing is an acceptable alternative. For example, agitation periods for elongated materials may need axtm be extended, while softer materials that break down easily may require a shorter period to minimize alteration of the particle size distribution. Note 1—Specification E provides criteria for the evaluation of agencies that perform the inspection of concrete during placement.

Where the supervising laboratory technician is supervising technicians who only test aggregates, the applicable astm c1077 tests are the aggregate tests listed in astm c1077 group. This shall include any potential conflicts that could be reasonably astm c1077 or perceived to impair the impartiality of their assessment.
