# Parts n.e.c. of machinery for processing tobacco

## 1. Scope and Applicability

This rule covers the factory-gate production of an accepted, separately supplied part whose declared function is in machinery for processing tobacco. The part, its drawing or part number, material grade, compatible machine, manufacturing route, and acceptance condition must be identified. A machined alloy-steel component is the representative route; the inventory cards name its concrete exchanges. For another verified material or route within this category, the data producer must add equally specific exchanges and route records before using the dataset. The cited metal-fabrication sources establish applicable process and collection requirements, not a universal recipe or benchmark for tobacco machinery parts. [Sources: `un-cpc-3-2025-notes`, `eu-pef-2021-annex-i`, `us-epa-clean-lines-2007`, `djordjevic-2018-conveyor`]

Complete tobacco-processing machinery, food or grain machinery parts, general packaging-machine parts, tobacco itself, installation, machine operation, repair service, and part disposal are outside this product rule. A part used only for packaging is not assigned here without evidence that it is a tobacco-processing-machine part. [Source: `un-cpc-3-2025-notes`]

## 8. Foreground Data Collection, Calculation, and Quality Rules

### Data Collection Protocols

| protocol_id | process_id | flow_role | record_type | raw_fields | collection_method | unit | frequency | temporal_coverage | site_scope | aggregation_rule | quality_evidence |
| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |
| `cp_mass` | `part_fabrication` | accepted reference product | acceptance and weighing record | model; configuration; serial number; accepted net mass M | Weigh the accepted complete unit on a calibrated scale, excluding transport packaging; reconcile the same configuration and acceptance record. | kg | each accepted configuration or representative accepted unit | declared reporting period | production site | M = accepted net mass of one complete unit of the same configuration | scale calibration; acceptance and configuration record |

### Calculation Rules

The collection protocols allocate each measured exchange directly per accepted unit. No external per-unit factor or item-to-mass conversion is imposed; the measured net mass M remains the reference quantity for that unit.

### Data Quality Requirements

| requirement_id | Applies to | Requirement | Evidence |
| --- | --- | --- | --- |
| `quality_identity` | finished part and inputs | Retain drawing, compatible machine, material grade, route, acceptance state, and supplier identity. | Approved drawing, bill of materials, acceptance and supplier records. |
| `quality_coverage` | foreground exchanges | Reconcile material input, accepted part mass, rejects, chips and other recorded waste for the same period and configuration; explain any gap. | Batch mass balance and stock reconciliation. |
| `quality_time` | meter and waste records | Use a common declared reporting period and show the allocation of shared utilities and waste to accepted units. | Dated meter, production and waste logs. |
| `quality_uncertainty` | unverified amounts and background data | Disclose estimates, missing exact flow identities, data age, geographic and technology mismatches, and excluded stages. | Data-quality statement and source documentation. |

## 9. Validation Rules

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| `validate_part` | reference output | Reject a dataset without the compatible tobacco-processing machine, part identifier, accepted configuration and measured net mass M. | `un-cpc-3-2025-notes` |
| `validate_exchange` | every inventory row | Verify direction, physical flow type, property, unit, inclusion condition, collection protocol and one accepted-unit basis; keep an unresolved UUID blank until exact identity is confirmed. | `eu-pef-2021-annex-i` |
| `validate_balance` | metal route | Reconcile recorded alloy-steel input, accepted part mass, chips, rejects and stock change without inventing a yield or scrap range. | `us-epa-clean-lines-2007` |
| `validate_waste` | conditional oil route | Include spent cutting oil only when the documented wet-machining route produces it; retain treatment evidence and avoid duplicate chip or oil accounting. | `us-epa-clean-lines-2007` |

## 10. Published Dataset Profile

| Field | Value |
| --- | --- |
| dataset_role | Foreground unit-process data package for one declared accepted part configuration. |
| downstream_use | Link to a process and lifecyclemodel for factory-gate assessment of the separately supplied part. |
| allowed_use | Configuration-specific manufacturing inventory with verified product and flow identities. |
| excluded_use | A generic benchmark for all tobacco machinery parts or a use-phase and end-of-life result. |
| required_metadata | Part and machine identity; drawing; grade; route; site; period; measured M; suppliers; inclusion conditions. |
| required_quality_disclosure | Measurement records, shared-record allocation, missing or proxy background data, and unresolved cutting-fluid UUID. |
