Rating = 5 corresponds to Z scores no greater than 1.0
Rating = 4 corresponds to Z scores greater than 1.0 but less than or equal to 1.5
Rating = 3 corresponds to Z scores greater than 1.5 but less than or equal to 2.0
Rating = 2 corresponds to Z scores greater than 2.0 but less than or equal to 2.5
Rating = 1 corresponds to Z scores greater than 2.5 but less than or equal to 3.0
Rating = 0 corresponds to Z scores greater than 3.0
If any of the individual results are less than or equal to a rating of 2, perform a brief labortory investigation in an attempt to document the potential
cause of this low rating (e.g. calculation error, equipment, or procedural). The documented results of this investigation should then be put on file in
the laboratory and kept for a period of no less than five years. This documentation should be made available to ODOT upon request. If any of the
individual results are less than or equal to a rating of 1 then the results of a completed laboratory investigation and copy of all calculations should be
immediately submitted to the OMM Aggregate Section. Detailed instructions regarding deadlines and other follow up instructions will be emailed to
these labs. If requested please submit all follow up documentation to: [email protected], or by mail to: OMM Aggregate
Section at 1600 W. Broad St., Columbus, Ohio 43213. Failure to respond in a timely manner may result in loss of S1069 laboratory and associated
producer/supplier prequalification.
The 2020 Round Robin study included a total of 146 participating laboratories. Each participating laboratory's results were entered into a combined
database and analyzed for basic statisics. This report displays the individual lab results submitted to the OMM Aggregate Section, the population
average, population standard deviation, Z score, and rating. The Z score indicates how many standard deviations away from the population average
each reported result is. Each rating is based upon a corresponding Z score range described below:

If any of the individual results are less than or equal to a rating of 2, perform a brief labortory investigation in an attempt to document the potential
cause of this low rating (e.g. calculation error, equipment, or procedural). The documented results of this investigation should then be put on file in
the laboratory and kept for a period of no less than five years. This documentation should be made available to ODOT upon request. If any of the
individual results are less than or equal to a rating of 1 then the results of a completed laboratory investigation and copy of all calculations should be
immediately submitted to the OMM Aggregate Section. Detailed instructions regarding deadlines and other follow up instructions will be emailed to
these labs. If requested please submit all follow up documentation to: [email protected], or by mail to: OMM Aggregate
Section at 1600 W. Broad St., Columbus, Ohio 43213. Failure to respond in a timely manner may result in loss of S1069 laboratory and associated

The 2020 Round Robin study included a total of 146 participating laboratories. Each participating laboratory's results were entered into a combined
database and analyzed for basic statisics. This report displays the individual lab results submitted to the OMM Aggregate Section, the population
average, population standard deviation, Z score, and rating. The Z score indicates how many standard deviations away from the population average
each reported result is. Each rating is based upon a corresponding Z score range described below:

If any of the individual results are less than or equal to a rating of 2, perform a brief labortory investigation in an attempt to document the potential
cause of this low rating (e.g. calculation error, equipment, or procedural). The documented results of this investigation should then be put on file in
the laboratory and kept for a period of no less than five years. This documentation should be made available to ODOT upon request. If any of the
individual results are less than or equal to a rating of 1 then the results of a completed laboratory investigation and copy of all calculations should be
immediately submitted to the OMM Aggregate Section. Detailed instructions regarding deadlines and other follow up instructions will be emailed to
these labs. If requested please submit all follow up documentation to: [email protected], or by mail to: OMM Aggregate
Section at 1600 W. Broad St., Columbus, Ohio 43213. Failure to respond in a timely manner may result in loss of S1069 laboratory and associated

If any of the individual results are less than or equal to a rating of 2, perform a brief labortory investigation in an attempt to document the potential
cause of this low rating (e.g. calculation error, equipment, or procedural). The documented results of this investigation should then be put on file in
the laboratory and kept for a period of no less than five years. This documentation should be made available to ODOT upon request. If any of the
individual results are less than or equal to a rating of 1 then the results of a completed laboratory investigation and copy of all calculations should be
immediately submitted to the OMM Aggregate Section. Detailed instructions regarding deadlines and other follow up instructions will be emailed to
these labs. If requested please submit all follow up documentation to: [email protected], or by mail to: OMM Aggregate

If any of the individual results are less than or equal to a rating of 2, perform a brief labortory investigation in an attempt to document the potential
cause of this low rating (e.g. calculation error, equipment, or procedural). The documented results of this investigation should then be put on file in
the laboratory and kept for a period of no less than five years. This documentation should be made available to ODOT upon request. If any of the
individual results are less than or equal to a rating of 1 then the results of a completed laboratory investigation and copy of all calculations should be
immediately submitted to the OMM Aggregate Section. Detailed instructions regarding deadlines and other follow up instructions will be emailed to
these labs. If requested please submit all follow up documentation to: [email protected], or by mail to: OMM Aggregate
Section at 1600 W. Broad St., Columbus, Ohio 43213. Failure to respond in a timely manner may result in loss of S1069 laboratory and associated

If any of the individual results are less than or equal to a rating of 2, perform a brief labortory investigation in an attempt to document the potential
cause of this low rating (e.g. calculation error, equipment, or procedural). The documented results of this investigation should then be put on file in
the laboratory and kept for a period of no less than five years. This documentation should be made available to ODOT upon request. If any of the
individual results are less than or equal to a rating of 1 then the results of a completed laboratory investigation and copy of all calculations should be

If any of the individual results are less than or equal to a rating of 2, perform a brief labortory investigation in an attempt to document the potential
cause of this low rating (e.g. calculation error, equipment, or procedural). The documented results of this investigation should then be put on file in
the laboratory and kept for a period of no less than five years. This documentation should be made available to ODOT upon request. If any of the
individual results are less than or equal to a rating of 1 then the results of a completed laboratory investigation and copy of all calculations should be
immediately submitted to the OMM Aggregate Section. Detailed instructions regarding deadlines and other follow up instructions will be emailed to
these labs. If requested please submit all follow up documentation to: [email protected], or by mail to: OMM Aggregate
Section at 1600 W. Broad St., Columbus, Ohio 43213. Failure to respond in a timely manner may result in loss of S1069 laboratory and associated

If any of the individual results are less than or equal to a rating of 2, perform a brief labortory investigation in an attempt to document the potential
cause of this low rating (e.g. calculation error, equipment, or procedural). The documented results of this investigation should then be put on file in
the laboratory and kept for a period of no less than five years. This documentation should be made available to ODOT upon request. If any of the
individual results are less than or equal to a rating of 1 then the results of a completed laboratory investigation and copy of all calculations should be
immediately submitted to the OMM Aggregate Section. Detailed instructions regarding deadlines and other follow up instructions will be emailed to
these labs. If requested please submit all follow up documentation to: [email protected], or by mail to: OMM Aggregate
Section at 1600 W. Broad St., Columbus, Ohio 43213. Failure to respond in a timely manner may result in loss of S1069 laboratory and associated

The 2020 Round Robin study included a total of 146 participating laboratories. Each participating laboratory's results were entered into a combined
database and analyzed for basic statisics. This report displays the individual lab results submitted to the OMM Aggregate Section, the population
average, population standard deviation, Z score, and rating. The Z score indicates how many standard deviations away from the population average
each reported result is. Each rating is based upon a corresponding Z score range described below:

If any of the individual results are less than or equal to a rating of 2, perform a brief labortory investigation in an attempt to document the potential
cause of this low rating (e.g. calculation error, equipment, or procedural). The documented results of this investigation should then be put on file in
the laboratory and kept for a period of no less than five years. This documentation should be made available to ODOT upon request. If any of the
individual results are less than or equal to a rating of 1 then the results of a completed laboratory investigation and copy of all calculations should be
immediately submitted to the OMM Aggregate Section. Detailed instructions regarding deadlines and other follow up instructions will be emailed to
these labs. If requested please submit all follow up documentation to: [email protected], or by mail to: OMM Aggregate
Section at 1600 W. Broad St., Columbus, Ohio 43213. Failure to respond in a timely manner may result in loss of S1069 laboratory and associated

If any of the individual results are less than or equal to a rating of 2, perform a brief labortory investigation in an attempt to document the potential
cause of this low rating (e.g. calculation error, equipment, or procedural). The documented results of this investigation should then be put on file in
the laboratory and kept for a period of no less than five years. This documentation should be made available to ODOT upon request. If any of the
individual results are less than or equal to a rating of 1 then the results of a completed laboratory investigation and copy of all calculations should be
immediately submitted to the OMM Aggregate Section. Detailed instructions regarding deadlines and other follow up instructions will be emailed to
these labs. If requested please submit all follow up documentation to: [email protected], or by mail to: OMM Aggregate
Section at 1600 W. Broad St., Columbus, Ohio 43213. Failure to respond in a timely manner may result in loss of S1069 laboratory and associated

If any of the individual results are less than or equal to a rating of 2, perform a brief labortory investigation in an attempt to document the potential
cause of this low rating (e.g. calculation error, equipment, or procedural). The documented results of this investigation should then be put on file in
the laboratory and kept for a period of no less than five years. This documentation should be made available to ODOT upon request. If any of the
individual results are less than or equal to a rating of 1 then the results of a completed laboratory investigation and copy of all calculations should be
immediately submitted to the OMM Aggregate Section. Detailed instructions regarding deadlines and other follow up instructions will be emailed to
these labs. If requested please submit all follow up documentation to: [email protected], or by mail to: OMM Aggregate
Section at 1600 W. Broad St., Columbus, Ohio 43213. Failure to respond in a timely manner may result in loss of S1069 laboratory and associated

cause of this low rating (e.g. calculation error, equipment, or procedural). The documented results of this investigation should then be put on file in
the laboratory and kept for a period of no less than five years. This documentation should be made available to ODOT upon request. If any of the
individual results are less than or equal to a rating of 1 then the results of a completed laboratory investigation and copy of all calculations should be
immediately submitted to the OMM Aggregate Section. Detailed instructions regarding deadlines and other follow up instructions will be emailed to
these labs. If requested please submit all follow up documentation to: [email protected], or by mail to: OMM Aggregate
Section at 1600 W. Broad St., Columbus, Ohio 43213. Failure to respond in a timely manner may result in loss of S1069 laboratory and associated

If any of the individual results are less than or equal to a rating of 2, perform a brief labortory investigation in an attempt to document the potential
cause of this low rating (e.g. calculation error, equipment, or procedural). The documented results of this investigation should then be put on file in
the laboratory and kept for a period of no less than five years. This documentation should be made available to ODOT upon request. If any of the
individual results are less than or equal to a rating of 1 then the results of a completed laboratory investigation and copy of all calculations should be
immediately submitted to the OMM Aggregate Section. Detailed instructions regarding deadlines and other follow up instructions will be emailed to
these labs. If requested please submit all follow up documentation to: [email protected], or by mail to: OMM Aggregate

If any of the individual results are less than or equal to a rating of 2, perform a brief labortory investigation in an attempt to document the potential
cause of this low rating (e.g. calculation error, equipment, or procedural). The documented results of this investigation should then be put on file in
the laboratory and kept for a period of no less than five years. This documentation should be made available to ODOT upon request. If any of the
individual results are less than or equal to a rating of 1 then the results of a completed laboratory investigation and copy of all calculations should be
immediately submitted to the OMM Aggregate Section. Detailed instructions regarding deadlines and other follow up instructions will be emailed to
these labs. If requested please submit all follow up documentation to: [email protected], or by mail to: OMM Aggregate
Section at 1600 W. Broad St., Columbus, Ohio 43213. Failure to respond in a timely manner may result in loss of S1069 laboratory and associated
