How to check labels and reports during ULPA acceptance? Consistency between model and actual product

ULPA filter acceptance, make sure that the model, serial number, size, grade and test conditions correspond to the actual product. When checking labels and reports for There must be no unexplained differences between outer box markings, finished product labels and inspection documents. The easiest step when inspecting the goods upon arrival is to sign for it after seeing that the model and quantity are correct - but once the correspondence between the label and the report is broken, the starting point for subsequent traceability will be lost. Aili Industry isHEPA/ULPA filters are bound to labels and serial numbers before leaving the factory. Finished product labels, test reports, and outer box markings correspond to the same numbering system. The correspondence between the three can be directly checked upon arrival and acceptance, without the need for inference.

1. Check key identities one by one: Multiple units of the same model must also correspond one-to-one

Orders, drawings and reports are connected by number, and multiple units of the same model should also be kept in one-to-one correspondence to avoid mixed use of records discovered after installation.

When a batch of filter elements of the same model arrives, if only the total number and model are checked, no one will confirm the number correspondence between individual units. Which unit is used to install which point during installation may not be the same unit as the one corresponding to the test report. Aili Industry isthe ULPA ultra-high efficiency filter is delivered, each filter element has a unique serial number, and the finished product label, test report and outer box identification correspond to the same serial number;When Non-standard ULPA filter items are also delivered by unit number, which can be checked one by one during acceptance. The relationship between levels and filtering requirements can be found inISO cleanliness level comparison。

2. Read label condition information: Level, air volume, efficiency should be read with conditions

The grade should be combined with the standard, the resistance should be combined with the air volume, and the efficiency should be combined with the particle size and method. When label information is simplified, it should be completed from supporting documents.

The finished product label usually only indicates the model, serial number, grade and size, and the test conditions of efficiency and resistance are in the test report. During acceptance, if you only look at the grade on the label and don't look at the test conditions in the report, you won't know what air volume and particle size this grade was obtained under. Aili Industry isThe ULPA ultra-high efficiency filter test report lists the test standards, test air volume and particle size conditions. When comparing the label with the report, the grades and conditions can be compared. For how to interpret the test report, please refer toHEPA FAQs and Selection Guide。

3. Abnormalities should be clarified first before release: labels falling off, serial numbers repeated, reported model discrepancies

When the label falls off, the number is repeated, or the reported model does not match, keep the photo and confirm it, and do not arbitrarily re-attach a new number on site to complete the process.

The handling method of label anomalies discovered during acceptance will directly affect subsequent traceability. If the label falls off, you should confirm the original number and check it back from the report or the outer box mark; if the number is repeated, it means there may be a problem with the factory marking process, and the batch should be suspended and confirmed; if the reported model does not match the actual product, you should first confirm whether the report or the product was sent wrongly. Aili Industrial has a binding record of labels and serial numbers during the factory process. When an abnormality occurs, it can be checked and confirmed from the manufacturing records instead of leaving it to the on-site judge. The relationship between sealing and acceptance can be referred toULPA ultra-high efficiency filter FAQ and selection guide。

4. The corresponding relationship between the outer box number and the filter element number must be clearly stated.

The marking rules for the outer box number and the filter element number can be different, but there should be a clear correspondence between the two. The outer box number is used for logistics and batch management, and the filter element number is used for single unit traceability. If the two do not match, it will be impossible to match the outer box information with the actual product upon arrival.

Aili Industry isWhen non-standard ULPA filters are delivered, the corresponding relationship is marked according to the packaging level. The numbers on the outer box, inner packaging and filter element label can be traced to each other. During acceptance, the filter element serial number can be found from the outer box number. Please refer to the division of labor between batch and single unit numbers.ULPA ultra-high efficiency filter FAQ and selection guide。

5. Related questions and answers

Do the outer box number and filter element number have to be exactly the same?
The identification rules can be different, but there should be a clear corresponding relationship, so that single unit traceability cannot be lost.

What should I do if the label is worn and cannot be seen clearly?
The numbering records that can be checked should be kept and the bids should be replenished according to regulations. The history cannot be cut off after renumbering.

There are two filter elements in a batch with the same number. What should I do?
The batch should be suspended and confirmed, and it cannot be accepted based on quantity alone. Repeated numbers indicate that there is a problem with the marking process and need to be checked back from the manufacturing records.
