# Battery-electric golf car manufacture

## 1. Scope and Applicability

This candidate PCR covers manufacture of new complete two-seat off-road battery-electric golf-course golf cars, narrower than CPC3.0 49116. Exclude snow vehicles, gasoline and hybrid golf cars, cargo/utility variants, multi-seat passenger shuttles, road-registered low-speed vehicles, passenger cars, spare parts, refurbishment and conversion. Include actual site fabrication, conditional finishing, assembly, factory charging, short driving/steering/braking and electrical acceptance, attributable rework and wastes. Exclude customer charging, golf rounds, passenger transport service, customer maintenance, assumed mileage/lifetime and end of life. No operating-service functional equivalence is established. Throughout this PCR one accepted finished unit means one whole configured golf car; Chinese 设备 has the same meaning.

## 3. Reference Flow

| Field | Value |
| --- | --- |
| What | Provide the declared complete accepted two-seat off-road battery-electric golf car |
| How much | 1 kg of the same complete accepted configured unit using measured net mass M |
| How well | Meet actual drawings and configuration-specific signed acceptance criteria for battery installation/charge state, wiring/polarity/insulation, controller setup, steering and brake checks, short factory driving, fluid leaks and delivered guards/accessories. Record instruments, conditions, duration and measured results; catalogue speed, range, capacity or rated power are not generic manufacturing acceptance or energy factors. |
| How long or cycle | One manufacturing delivery; no assumed golf-car driving lifetime or service cycle |
| reference_flow_link | finished_machine |

| Field | Value |
| --- | --- |
| Reference amount | 1 |
| Reference product flow | Motor vehicles, for the transport of persons, specially designed for travelling on snow, golf cars and similar vehicles `2eafcec4-e441-447e-9ef9-40c4722c9ec9` |
| Reference flow property | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` |
| Reference unit group | Units of mass `93a60a57-a4c8-11da-a746-0800200c9a66` |
| Reference unit | kg |
| Required qualifiers | model/serial/batch; two-seat off-road battery-electric status; actual chassis material and stock/finished-module boundary; battery chemistry/model/count/mass/charge state and filled condition; motor/transaxle/controller/harness inclusion; body, seat, wheels/tyres, steering, brakes and suspension; installed canopy/bag support and accessories; retained fluids; empty clean state; measured M; off-board charger excluded; manufacturer/site/period; supplier gates, actual routes, factory tests and packaging scope |

Weigh the same complete accepted clean empty unit using calibrated scales.

Catalogue approximate curb, dry or gross weight is not M. Battery capacity is not consumed factory electricity. Kilogram normalization does not equate driving range, payload or golf service; the broad public reference name is restricted to this actual golf-car configuration, excluding snow and other variants.

## 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 | M = accepted net mass of one complete unit of the same configuration in kg; collect using cp_mass. |
| `energy_units` | electricity rows | Net calorific value `93a60a56-a3c8-11da-a746-0800200c9a66` | MJ | Preserve the meter unit; convert kWh to MJ using exactly 1 kWh = 3.6 MJ. Do not interpret the electricity property name as a combustion inventory. |
| `volume_units` | groundwater rows | Volume `93a60a56-a3c8-22da-a746-0800200c9a66` | m3 | Retain measured volume and its conditions; do not invent gas density, water density or calorific value to switch to mass or energy. |

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |
| `tyre_count_units` | tyre | Number of items `01846770-4cfe-4a25-8ad9-919d8d378345` | Item(s) | Count actual installed finished tyres per accepted unit using cp_assembly; preserve public count property and normalize q_item/M without converting the exchange to kg. Separately weigh tyres only for physical installed-mass reconciliation. |

## 5. System Boundary

### Boundary Abstraction

| Field | Value |
| --- | --- |
| declared_starting_condition | Materials and configured components received at declared supplier gates, with no implicit upstream steelmaking or component fabrication in foreground |
| starting_condition_role | Manufacturing input boundary for an accepted complete unit |
| product_classification_scope | Complete two-seat off-road battery-electric golf cars within broader CPC49116 context |
| recursive_input_rule | A purchased complete unit used as an input is a separately declared upstream product. Do not recursively regenerate this category; distinguish new production from refurbishment. |
| upstream_dataset_requirement | Link input-specific upstream datasets matching material, finished-component gate, geography, voltage and treatment state. Missing links remain disclosed coverage gaps. |
| disclosure | Report foreground factory stages, outsourced operations, component content, incoming transport coverage, protective packaging gate, capital-equipment policy and every exclusion; no complete cradle-to-gate claim without verified upstream and logistics closure. |

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| `manufacturing_gate` | foreground | Include every actual operation and attributable rework from declared received inputs through factory acceptance; distinguish purchased parts from site fabrication to prevent duplication. Use documented route records. |  |
| `conditional_finish` | finishing | Activate only documented finishing operations and chemical recipes. Manufacturer examples establish possible routes, not universal requirements or recipes. |  |
| `exclude_customer_use` | golf_service | Exclude customer charging, driving and golf service, maintenance and disposal. Include actual factory charging and short acceptance trials with their measured materials, AC-input energy and identified wastes/emissions. No passenger transport or golf service is included. |  |

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| `charger_delivery_boundary` | reference | Declare actual installed accessories and retained fluids in M. Off-board charger and loose equipment are separate products outside M, even if invoiced together. Only an actually installed on-board charger is included as its own physical input and in M. Transport disassembly requires part-level reconciliation and a calibrated summed net mass for the same completed acceptance configuration; no catalogue mass substitution. |  |

## 6. Process Inventory Structure

### Process Map

| process_id | process_name | inclusion | inclusion_condition | role | quantitative_reference |
| --- | --- | --- | --- | --- | --- |
| `forming` | Stock cutting, forming and machining | conditional | Only when the site fabricates these parts; otherwise record purchased finished parts separately | foreground manufacturing | per 1 kg reference flow; collected per one accepted finished unit |
| `joining` | Structural welding and dressing | conditional | Only when the site joins structural parts by welding | foreground manufacturing | per 1 kg reference flow; collected per one accepted finished unit |
| `wet_surface` | Aqueous cleaning and preparation | conditional | Only when aqueous cleaning or conversion treatment is actually performed; activate individual rows from the documented recipe | foreground manufacturing | per 1 kg reference flow; collected per one accepted finished unit |
| `powder_finish` | Powder application and curing | conditional | Only when actual finishing uses powder; electrical curing rows only for actual electrically cured powder | foreground manufacturing | per 1 kg reference flow; collected per one accepted finished unit |
| `assembly` | Configured golf-car assembly | required | Every accepted complete unit; activate component rows only when actually installed | foreground manufacturing | per 1 kg reference flow; collected per one accepted finished unit |
| `acceptance` | Factory acceptance and net-mass determination | required | Every accepted complete unit | foreground manufacturing | per 1 kg reference flow; collected per one accepted finished unit |
| `packaging` | Shipment protection at factory gate | conditional | Only when shipment protection is inside the declared delivery gate; disclose its exclusion otherwise | foreground manufacturing | per 1 kg reference flow; collected per one accepted finished unit |

Process records are separate contributors to one final accepted output, not seven separately traded reference products. Retain traceable internal-part transfer and bill-of-material records; internal transfers cancel within this foreground and do not receive duplicated upstream burdens. The cards below are explicit route-conditioned exchanges. Add each actual additional part, chemical, fuel, packaging piece, wastewater stream or measured elementary substance as its own identified row; absence of a card is not a cut-off permission. For outsourced finishing, replace site chemistry and energy with the exact purchased service or finished-part record and disclose its coverage.

## 7. Allocation and Co-product Handling

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| `direct_attribution` | shared_operations | Use job tickets and submetering before allocation. Where a common meter remains, require a measured causal driver such as machine-hours for the identified operation, with all participating jobs and idle load disclosed; divide the attributable quantity by accepted units of the same configuration before mass normalization. | `ghg-product-allocation-2011` |
| `coproduct_decision` | saleable_outputs | Do not assume scrap is a co-product. Disclose destination and legal/product status. If multiple saleable co-products actually occur, seek subdivision; justify a physical relation or, when unavailable, documented economic/other allocation with sensitivity. No universal mass share or avoided-steel credit is prescribed. | `ghg-product-allocation-2011` |

### Calculation Rules

| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
| --- | --- | --- | --- | --- | --- |
| `normalize_mass` | all inventory rows | q_ref = q_item / M; q_item = exchange amount per one accepted finished unit; q_ref = exchange amount per 1 kg reference flow. | q_item; M; cp_mass | q_ref |  |

The finished_machine output is fixed at 1 kg and is not divided again. Apply the conversion to each other applicable row using the same configuration and batch; quantity numerator units remain unchanged. Mixed configurations must be separated, not averaged by count with a catalogue mass.

### Data Quality Requirements

| requirement_id | Applies to | Requirement | Evidence |
| --- | --- | --- | --- |
| `configuration_trace` | all rows | Trace every input to installed BOM, route and accepted unit; supplier finished parts do not also receive raw-stock burdens. Disclose remaining components as missing coverage until separate atomic records are added. | drawings, BOM, supplier receipts |
| `basis_quality` | cp_mass | M must be positive measured net mass, with the same delivered configuration, fluid state and acceptance gate as all collected exchanges. | calibration and weighing records |
| `coverage_quality` | all processes | Document full batch temporal coverage, meter overlap, rejects, rework, stock changes, outsourced stages and unmeasured emissions. A missing record is unknown, not zero or not_applicable. | ledger, coverage matrix and measurement uncertainty |
| `chemistry_quality` | wet_surface; powder_finish | Verify recipe, concentration and SDS for each supplied formulated chemical; characterize each outgoing waste stream and identify treatment separately from environmental emissions. | recipe, SDS, analyses and transfer tickets |

## 9. Validation Rules

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| `validate_reference` | reference | Reject missing qualifiers, passenger/payload-loaded, battery-excluded or shipping-gross mass substitution, non-positive M or mismatch between configuration, cp_mass and finished_machine. Require 1 kg output and explicit normalize_mass on every non-reference applicable row. |  |
| `validate_atomic` | inventory | Require one physical exchange per row, verified public identity when supplied, correct property/unit, localized display and medium. Unresolved UUIDs do not authorize proxy substitution or mixed rows. |  |
| `validate_balance` | coverage | Reconcile installed mass, stock, waste, retained fluids and purchased parts using the actual BOM; independently reconcile installed battery, chassis, drive, body and wheel/brake/suspension module content with measured BOM mass; count-property tyres retain Item(s), with separately measured tyre mass used only in the physical balance. Reconcile battery water issue, retention, waste and measured charging emissions without a default hydrogen factor. Reconcile utilities by stage; internal transfers cancel. Explain differences against recorded measurement uncertainty, without a fabricated numerical tolerance. |  |
| `validate_completeness` | dataset | Check every conditional stage against route evidence. Require missing chemicals, parts, test media and actual emissions to be split and collected before claiming a complete inventory; prohibit cradle-to-gate or service comparisons while upstream or functional coverage is incomplete. |  |
| `validate_allocation` | shared_operations | Require complete driver records and justification for allocation and scrap treatment; document sensitivity where another defensible allocation may change results. | `ghg-product-allocation-2011` |

## 10. Published Dataset Profile

| Field | Value |
| --- | --- |
| dataset_role | Manufacturing foreground process for a configured accepted unit |
| downstream_use | secondary_dataset; background_dataset |
| allowed_use | Input to a declared golf-car supply model with identical configuration and disclosed upstream coverage |
| excluded_use | Customer charging, golf rounds or passenger transport service; performance comparison across battery/frame/brake configurations without separate functional modelling |
| required_metadata | Model, configuration, empty state, M, retained fluids, manufacturer/site, reporting period, process route, voltage/geography, supplier gates, transport/packaging scope and allocation |
| required_quality_disclosure | Measured versus estimated quantities; unresolved identities; unmeasured emissions and components; upstream linkage completeness; uncertainty, data age and configuration limitations |
| update_trigger | Changed battery chemistry/model/count/pack boundary, chassis or body material, motor/controller/charger, braking/suspension, installed accessories, BOM, fluid/cleaner/coating recipe, purchased component, energy mix, acceptance or net-mass protocol |
