# Parts for the goods of subclasses 47221 to 47223

## 1. Scope and Applicability

This PCR describes factory-gate production of a separately supplied, finished part designed for a telephone set or communication apparatus in the CPC 47221–47223 host set. A concrete data package must name the part, compatible host, technology and production route. The category flow is a mass reporting identity, not permission to compare unlike parts by mass alone. Production of a complete telephone, router or base station is outside this part-level reference. [un-cpc-3-2025; itu-l1410-2024]

## 2. Product Category Identity

| --- | --- |
| What | A declared dedicated part that performs a specified function in a compatible telephone or communications apparatus |
| How much | 1 kg net mass of accepted finished parts of one declared part specification |
| How well | Pass the declared inspection and compatibility specification; disclose part type, materials and performance criteria |
| How long or cycle | One completed production lot to the factory gate; service lifetime and use are not modeled |
| reference_flow_link | finished_part |

| Reference amount | 1 |
| Reference product flow | Parts for the goods of subclasses 47221 to 47223 `bf7766aa-8f63-4869-bd70-2090483f4437` |
| Reference flow property | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` |

A mass result is comparable only for parts with equivalent function, quality and boundary. The producer measures accepted net output mass for the same lot used by all inventory protocols. [itu-l1410-2024]

## 4. Measurement and Unit Rules

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |
| reference_mass | reference product | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | Weigh accepted finished parts on a calibrated scale after inspection and before transport packaging; exclude rejected units and the corrugated box. Collect using cp_finished_mass. |
| inventory_basis | all inventory rows | Physical flow property of each selected flow | row unit | Record attributable lot quantities per 1 kg reference flow using the same accepted net output mass and production period; preserve board area in m2, material masses in kg and electricity in kWh. |


## 5. System Boundary

Cradle-to-gate accounting includes upstream datasets for purchased boards, ICs, solder paste, aluminium sheet, electricity and packaging, plus the declared on-site fabrication, assembly, testing and packing operations. Exclude host-device assembly after the part leaves the gate, distribution, use and end-of-life from this part dataset. Disclose any externally performed process as an upstream dataset. [itu-l1410-2024]

### Boundary Abstraction

| Field | Value |
| --- | --- |
| declared_starting_condition | Purchased materials and components at the part producer gate, with supplier production represented upstream |
| starting_condition_role | Explicit foreground inputs with linked upstream datasets |
| product_classification_scope | Dedicated separately supplied parts for host goods 47221, 47222 and 47223 |
| recursive_input_rule | Record a purchased same-category part as a distinct input with its own upstream dataset and stop tracing at that declared supplier boundary; do not silently merge it into the reference output |
| upstream_dataset_requirement | Use composition- and geography-matched supplier datasets where available; disclose missing upstream processes and proxy limits |
| disclosure | Report part identity, route, supplier boundary, included stages, exclusions and all deviations |


| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| boundary_gate | foreground part production | Include applicable on-site fabrication, module assembly, testing and packing until acceptance at factory gate; disclose route-specific omissions. | itu-l1410-2024 |
| boundary_supplier | purchased component inputs | Keep purchased-component upstream burdens and process boundary explicit; avoid double counting a supplier stage as on-site fabrication. | itu-l1410-2024 |


## 6. Process Inventory Structure

The cards below specify atomic exchanges for the common board-module and aluminium-sheet routes. Apply each card only when its stated physical operation occurs. A different part technology must disclose its own atomic exchanges and seek method review before treating this list as complete. [itu-l1410-2024]

### Process Map

| process_id | process_name | inclusion | inclusion_condition | role | quantitative_reference |
| --- | --- | --- | --- | --- | --- |
| part_manufacturing | Part fabrication, module assembly, testing and packing | required | Declare which of board population, sheet fabrication and packing actually occur; each conditional card follows that route | foreground production of one accepted part type | per 1 kg accepted finished part |
