01 Answer first
How should water bottle code verification and rejection be validated?
Control the source data and recipe, define acceptable code content, position and readability, challenge representative missing, wrong, blurred, misplaced or low-contrast conditions within the selected system’s capability, track each test bottle to the reject point, confirm containment, test bypass and fault responses, and reconcile results with event and production records.
02 Where it fits
Position in the project journey
Identification-control validation - after code and equipment selection and before production release.
03 Buyer inputs
What the buyer should prepare
- Approved code content, format, location, change authority and market requirements
- Lot-definition, production-record and backward/forward retrieval procedure
- Acceptable print and verification criteria plus quality release authority
- Reject handling, reconciliation, access and record-retention requirements
04 Allot Tech and manufacturing-resource inputs
What should be clarified or provided
- Coder, data-transfer and recipe-control architecture
- Verification capability, limits, tracking distance and reject mechanism
- Fault, bypass, reject-bin, line-stop and reset behavior
- Challenge method, audit data, FAT report and site-dependent verification plan
Allot Tech coordinates requirement, quotation and project communication. Detailed engineering, manufacture, testing, documentation and confirmed service are performed by selected manufacturing resources according to the signed scope.
05 Technical scope
Questions and work to control
Control the Master Data Before Printing
Define where lot, date or other approved information originates, how recipes are selected and checked, who can edit them and how changes are recorded. Verification cannot correct an uncontrolled master-data decision.
- Approved code format and data owner
- Recipe selection and line-clearance check
- Role-based change authority
- Audit trail and production-record linkage
Build a Capability-Matched Challenge Set
Use safely prepared examples for the defects the installed verifier is intended to detect and keep unsupported defects outside its claim. Include good controls, different positions or contrasts where relevant and repeat tests after approved format or recipe changes.
- Missing and wrong-code cases
- Blurred, incomplete or misplaced cases
- Low-contrast cases within the approved material range
- Known good controls and repeated trials
Prove Tracking, Rejection and Record Reconciliation
A detection signal must stay linked to the physical bottle until confirmed rejection or line stop. Test spacing changes, starts, stops, full reject bins, bypass permissions and reset behavior, then reconcile challenged bottles with reject and event records.
- Inspection-to-reject tracking logic
- Reject confirmation and containment
- Fault, bypass and full-bin response
- Challenge count, event log and retrieval reconciliation
Buyer questions answered
Practical answers before you request a quotation
Does a code-presence sensor verify the correct lot?
Only if the selected system is designed and validated for content verification; presence alone is a narrower check.
Should deliberately defective bottles be used?
Use an approved safe challenge method that protects product and people and keeps test units under controlled disposition.
What if the reject device fails?
The approved controls philosophy should define alarm, line stop or other fail-safe response and affected-product assessment.
Does coding alone provide complete traceability?
No. Master data, material and production records, lot definition, distribution records and retrieval procedures also need control.
06 Responsibility
Assign the owner before the work is due
Land, building and civil work, permits, import and customs, local taxes, site utilities, unloading, lifting, local labor, travel support and commissioning materials are not automatically included. Confirm every responsibility before order.
07 Common risks
What commonly creates avoidable uncertainty
- The verifier confirms code presence but not the approved content
- Bottle tracking is lost between inspection and the reject device
- Rejected bottles remain accessible or re-enter production without control
- Operator access permits unrecorded recipe changes or verification bypass
08 Acceptance or completion
How to know the stage is complete
The control is validated when approved challenge cases produce the expected detect, track and reject response, failed or bypassed functions create the agreed alarm or stop, reject containment and counts reconcile, event records are retrievable, and traceability retrieval succeeds under the buyer procedure.
09 Required documents
Records that support the decision
- Approved code master-data and print specification
- Verification, tracking and reject functional description
- Challenge set, protocol and result report
- Access, event-log, reconciliation and retrieval records
Evidence basis
Official references and project limits
These primary sources support the general planning principles used in this guide. The rules, evidence and responsible authority for the actual project country must still be confirmed locally.
