SECURING SAMPLES

INTRODUCTION

This IM is intended to provide instructions on how to secure verification samples.  Verification samples can be transported by the contracting authority without additional security measures.  Verification samples not transported by the contracting authority must make use of the following procedures unless directed otherwise by the District Materials Engineer (DME).  For materials not able to be secured through one of the following methods, contact your local DME for additional guidance. 

PROCEDURES

To obtain the required security supplies, contact your local District Materials Office.  These are examples of the security supplies available.

TAMPER PROOF TAPES

Tamper proof tapes can be used to secure boxes, binder tins, and other similar containers. 

Here are some examples of how the tamper proof tape can be utilized.

Standard practice is to place the 193 form inside the box prior to securing the box.  For loose asphalt mix, on the outside of the box several pieces of information are recorded including the date, mix design number, sender’s number, project number and sample number.

When using the numbered security tape the number is recorded on the 193.  The paper 193 (if used) must accompany the sample.  The secured binder tin may be placed inside the box of loose mix.

TAMPER PROOF TAGS

Tamper proof tags are used to secure bags.  Examples of the tamper proof tags and how they are applied to the bags are as follows:

The security number on the tag is recorded on the 193 form and the paper 193 (if used) placed inside the bag prior securing the bag for delivery. 

DOCUMENTATION

The identification number on the tamper proof tag is recorded on the 193 form and the paper 193 (if used) is then secured with the sample prior to submitting to the District Materials Office.  Arrangements can be made to submit the 193s electronically with notification to the DME.
