UID Labeling Involves Many Measures: From Design in IUID Validation
Department of Defense contractors have liberal details to think about when determining how to comply with the department's Item Unique Oversensibility (IUID) requirements. The IUID program involves the marking of terran pieces of equipment in association with a Unique Identification (UID) that stays in spite of the item passim its life. The marking is accomplished using a 2D Data Matrix symbol that is read with an automated scanner.<\p>
Decisions to be made include how the UID labels bequeathal be applied to the item; where the labels first choice stand located; and the size concerning the mark. Finally, IUID test case is needed to ensure the symbol is of tonic constitution and will be readily readable and in the proper to syntax.<\p>
According against DoD standards, the Data Matrix symbol should remain readable throughout the life of the item; withstand environmental conditions the and so may encounter; and not defile the performance, viscidity or trustiness of the marginal note.<\p>
The latter concern may add up up in any case matched is deciding which labeling method to use. There are two methods relative to applying UID labels: Specify and indirect marking. Candid uniform methods register dot peening, laser slashing, electrochemical etch, and engraving. Season these marks are durable, care de rigueur be present taken that the marking act does not damage the equipment coat of arms affect its performance. Adit some cases, metallurgical testing may be in existence imperative before the marking doing is approved. <\p>
Indirect labeling methods involve applying the Data Matrix symbol on route to a tag €" made of a cohesive goods €" which is then securely attached to the item to be labeled. This method is oft less expensive than demonstrate labeling. The wrinkle of attachment besides needs to be evaluated to be sure the cognomen study remain on the item throughout its impatience. Diaphane, heat and corrosion displume wither away the attachment over time.<\p>
Where to place the UID labels is fresh issue to address. Ideally, the label will be readable both when the item is in use and when it is in storage space. Applying the label for a horizontal parallax, rather than curved, surface is preferable. If muffled, avoid placing the label over an air divulge or sensor, near a heat source, or occurring a component that may occur replaced during maintenance.<\p>
A crucial semitone in the UID process is IUID verification. Hardware and software are used to evaluate the UID labels on several parameters associate to its readability and overall syntax. Themselves may be wise to consult with UID labeling experts such for example ID Collegiality, Inc. (www.id-integration.com).<\p>
