When certificate sources conflict, how we show them
When two public certificate lines disagree, both stay, each with its source name and the day it was read. This page is a template. It names no mill and prints no live certificate number.
- ›If a supplier webpage and a public directory disagree on the number or the expiry, both lines stay.
- ›Each line carries the source name and the day that source was read. The less convenient line is not dropped.
- ›The two lines are not merged into one number, and one line is not quietly rewritten as the other.
- ›The table on this page uses 〔A〕 and 〔B〕 as placeholders. They are not certificate numbers, and they are not a mill.
- ›A conflict is not closed by deleting a source. It closes when one chain can be checked: same holder, one current number, still in date.
Both lines stay
Two public sources can name different certificate numbers, or different expiry dates, for what looks like one claim. The page keeps both. Each line records where it came from and the day it was read.
Nothing on this page is a live certificate. 〔A〕 and 〔B〕 are slots. They are not issued numbers, and the holder cell is not a company. Do not read the template as a result for any mill.
Template: both lines, neither chosen
Placeholders only. 〔A〕 and 〔B〕 stand in for certificate numbers. Each column has its own checked date. No mill is named.
| Field | 〔example〕 supplier webpage | 〔example〕 public certification directory |
|---|---|---|
| Holder | 〔example holder〕 | 〔example holder〕 |
| Issuing body | 〔example body〕 | 〔example body〕 |
| Certificate number | 〔A〕 | 〔B〕 |
| Scope | 〔example scope〕 | 〔example scope〕 |
| Expiry | 〔example date〕 | 〔example date〕 |
| Checked date | 〔example date 1〕 | 〔example date 2〕 |
Both columns stay. The checked date is the day that column's source was read. This table does not pick 〔A〕 or 〔B〕, and it does not print a live number.
What the page does with the disagreement
The template above is the only certificate block on this page. The rows below are the rule for that shape.
| Situation | What is shown |
|---|---|
| The two sources disagree | Both lines, with the source name and the checked date. Neither line is dropped. |
| A required field is missing | The certificate block is not rendered. A shorter “certified” line is not put in its place. |
| The sources later match | Same holder, one current number, still in date. That is a new chain a reader can check, not a silent edit that deletes the older line. |
〔A〕 and 〔B〕 are not certificate numbers. Substituting an unchecked name or a live number into this template is out of scope for this page.
What this template is not
Keeping both lines is the record of a disagreement. It is not a ban, and it is not a score. A reader who wants the six fields copied from a real certificate uses the verification guide. The rule that the word ISO9001 is not itself a hold-cert claim is the companion page in this set.
Until the sources agree, the page does not choose the webpage line because it is the one the supplier printed. It also does not choose the directory line because it looks more official. Both checked dates stay visible.
Frequently asked questions
Does a conflict mean the supplier is in worse standing?
No. Both lines stay so a reader can see the disagreement, each with its source and the day it was read. That is not a ban, and it is not a score.
Can the page keep only the number from the supplier webpage?
No. If the public directory line differs, that line stays too, with its own checked date. Dropping it does not close the conflict. 〔A〕 and 〔B〕 in the template are placeholders, not a choice of one number.
What would a matching chain look like, without a real number?
The same holder on both sources, one certificate number, still in date, and a checked date for each source you read. Until that chain is on file, 〔A〕 and 〔B〕 stay side by side. Those brackets are not issued numbers, and this page does not fill them in.
