About this deal

Marking quality control documents has never been easier. Trodat's Printy 4912 self-inking QC inspection stamp features the words, 'QUALITY CONTROL PASSED' or 'QUALITY CONTROL FAILED', alongside space to sign your name and date, clearly showing the jobs you've examined.

After 10 minutes, you will be able to (1) understand the reliability of an inspector’s findings and (2) take more informed decisions based on an inspection report. Lower Control Limit: In a QC chart, the lower control limit (LCL) line indicates the number below which any single data point is outside of statistical control because of “special cause” variation. In this article, I explain three fundamental concepts that every buyer should be familiar with when it comes to quality control and inspections: A quality control template is crucial to plan and document your quality control goals, production effectiveness, and testing efforts, as well as to determine room for improvement.In part 1, we explained the different inspection levels that can be used. Another basic concept rings familiar to many importers but is often not clearly understood: the AQL (Acceptance Quality Limit).

Next, real-world data must be collected -- such as the percentage of units that fail -- and the results reported to management personnel. After this, corrective action must be decided upon and taken. For example, defective units must be repaired or rejected, and poor service repeated at no charge until the customer is satisfied. If too many unit failures or instances of poor service occur, a plan must be devised to improve the production or service process; then that plan must be put into action. Decision or Corrective Action: Enter details of any decisions or corrective actions resulting from the QC testing data. Sample Size: Enter the number of observations or replications in the production sample to compare with your QC standards. In ISO-2859 is clear how to change from normal to tightened, and from tightened to normal, but that I mention in last paragraph is difficult for me to understand. A professional inspector will notice defects and evaluate their category by himself. But it is better if the buyer himself describes the most frequent defects and assigns categories to each one.When to inspect? The best is clearly during production after enough finished products have come off the lines. As the 4 products might not all be processed at exactly the same time, it might be preferable to send an inspector at different times. And if an inspection is failed, a re-inspection can probably be performed at the supplier’s charge.
