Thank you for your interest in the International Digital Image Correlation Society’s “A Good Practices Guide for Digital Image Correlation”. The introductory presentation of the Guide describes the development process, intended scope, and general overview of the Guide. In order to receive a copy of the draft version of the Guide itself, you must opt-in to vote, as described below.

On this page, you will find information concerning the public comment period and voting process to ratify the Guide. The intention of the comment period is to get feedback from a broad audience (manufacturers, users, academics, and consumers) on the draft version of the Guide. Everyone with a vested interest in DIC is welcome to review, comment on, and vote on the Guide (regardless of status as a member of iDICs).

iDICs desires to produce the best possible guide within the described scope, and is planning on distributing it electronically without charge after is has been approved through this voting process.

Thank you again for participating in this process. We look forward to hearing your input.


Mark A. Iadicola and Elizabeth M. C. Jones
Co-chairs of the iDICs Standardization, Best Practice, and Uncertainty Quantification Committee

Review and Voting Process

To participate in the public comment period and voting process, you will need to opt-in to the review by December 4, 2017. This requires that you email with the following information:

  • full name
  • title
  • affiliation
  • email
  • if you are an iDICs member (yes/no)

We will then send you a copy of the Guide to review and the voting and comment form. Once you opt-in to vote, you are expected to vote! A lack of response will be treated as approval without comment.

Voting and comment options

To cast your vote, simply complete the voting and comment form that you received with the draft copy of the Guide, and email the completed form to by January 15, 2018.

Each person who opts-in will have the following voting options:
(1) Approve without comment,
(2) Approve with comments and suggested revisions,
(3) Disapprove with comments (at least one technical) and suggested revisions,


• Abstain is not an option if you opt-in; abstain or no response by the deadline (January 15,2018) will be counted as “Approve without comment”
• Disapprove without any comments and suggested revisions will be treated as Abstain.
• Disapprove with only general and/or editorial comments and without at least one technical comment and associated suggested revision will be treated as Approval with comment. (That is, you cannot disapprove based on editorial or general comments alone; you must have a technical basis for disapprove.)
• Comments without suggested revisions will be treated as no comment (i.e. Approve without comment).
• Comments and suggested revisions that are NOT submitted in the required comment form by the deadline (January 15, 2018) may be ignored during the review process.

Each comment will have to be categorized as to the “Type of Comment” to determine the level of review required. The “Types of Comments” are:
(1) editorial
(2) general
(3) technical
Explanations and examples of the different types of comments are provided in the voting and comment form [link file “iDICs comment form.xlsx”].

Voting follow-up and decision process

After the close of the comment period (January 15, 2018), the Working Group Chair and a few members of the Working Group will tally the official votes, organize the comments by section and topic, and perform a classification check on the comments. Reviewers may be contacted to clarify their comments. Note that reviewers may choose to withdraw their comments at any time if they so choose.

Editorial and General Comments

The Working Group Chair and a few members of the Working Group will review the general and editorial comments and may revise the Guide accordingly.

Technical Comments

All technical comments will be reviewed by the Working Group, and a decision will be assigned to each technical comment as follows, with justification as appropriate:
• Persuasive
• Non-persuasive
• Unrelated

Final revision process

If a 2/3 majority approval of the Guide is received, the Working Group may choose to revise the Guide to address the persuasive technical comments, at the discretion of the Working Group. If persuasive technical comments are not addressed in this version of the guide, they will be flagged for consideration in the next edition of the guide. A subset of the iDICs Executive Board (that are not in the Working Group) will review the technical comments and decisions assigned by the Working Group. This subset of the Executive Board will also review the revised version of the Guide for final approval/publication, or may request further revision.

If a 2/3 majority approval is NOT received, then the draft will be taken under revision. All technical comments should be addressed by the Working Group as part of this revision. After the Working Group has revised the Guide, a subset of the iDICs Executive Board (that are not in the Working Group) will review the revised version of the Guide and will decide if a second public comment period and round of voting is required.

Future Directions

The first edition of the Guide contains a wealth of information, but is by no means 100% complete. We intend to continue to improve and expand the Guide by releasing future editions. On the voting and comment form, you will have an opportunity to indicate which topics the Working Group should focus on for future work on the Guide.
