# Automatic goods vending machines

## 1. Scope and Applicability

This PCR covers factory-gate production of a new, complete automatic machine that accepts payment or another authorized transaction and dispenses packaged goods without on-site labour intervention. Covered configurations include ambient, heated, refrigerated, and combination machines when their configuration is declared. The foreground boundary includes receipt of purchased assemblies, final mechanical and electrical assembly, model-specific acceptance testing, refrigerant charging where applicable, and packaging for dispatch.

The PCR excludes machines that dispense only cash, tickets or services; automated teller machines; attended retail cabinets; beverage preparation or food-processing equipment whose principal function is processing rather than dispensing pre-packaged goods; loose spare parts; and rebuilt, repaired or refurbished machines. Manufacture of purchased components is represented by supplier-specific upstream datasets. Distribution after the factory gate, stocking goods, installation, use, maintenance and end-of-life are outside the declared product system unless a study adds them as separately disclosed modules.

| reference_flow_link | Output row `finished_vending_machine` from process `machine_assembly_testing_packaging` |

| Field | Value |
| --- | --- |
| Reference amount | Measured net mass in kg of one accepted finished machine, excluding dispatch packaging |
| Reference product flow | Automatic goods vending machines `0b858929-f07a-4c83-b3f7-fa69f1fa8e0d` |
| Reference flow property | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` |

## 4. Measurement and Unit Rules

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |
| `reference_net_mass` | reference product and all mass-normalized inventory | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | Weigh or otherwise verify the net mass of one accepted machine without dispatch packaging; report packaging as separate input rows and do not substitute shipping mass for reference mass. |
| `batch_to_machine` | batch production records | Mass, energy or item count as recorded | kg, MJ or item | Use model-specific batches. Divide batch totals only by accepted machines of the same declared model and retain rejected-unit and work-in-progress reconciliation. |
| `electricity_conversion` | assembly and acceptance-test electricity | Net calorific value `93a60a56-a3c8-11da-a746-0800200c9a66` | MJ | Preserve the meter reading in kWh and convert to MJ with 1 kWh = 3.6 MJ; state voltage, grid geography and meter boundary. |
| `refrigerant_species_mass` | refrigerant charge and charging loss | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | Keep each refrigerant species in a separate row. Reconcile purchased, returned, recovered, inventory-change, installed-charge and measured-release masses; never report a combined refrigerant amount. |

## 5. System Boundary

The foreground boundary begins when purchased cabinet, mechanical, electronic, refrigeration and packaging items and factory utilities cross into final machine assembly. It ends when the accepted machine and its separately recorded dispatch packaging are ready at the factory gate. Supplier production of purchased items is upstream; use and end-of-life are downstream and excluded from the core result.

### Boundary Abstraction

| Field | Value |
| --- | --- |
| declared_starting_condition | Purchased cabinet/frame, mechanical and electronic assemblies, optional refrigeration equipment and refrigerant, packaging, electricity and conditional cleaning water are received at the final assembly site |
| starting_condition_role | Factory-gate modular assembly starting point |
| product_classification_scope | Complete new automatic goods vending machine; parts and rebuilt machines are outside this product identity |
| recursive_input_rule | A complete used vending machine entering rebuilding is not recursively treated as a purchased new-machine input; model that route in a separately disclosed remanufacturing dataset |
| upstream_dataset_requirement | Use supplier- and geography-specific upstream datasets for every purchased component, refrigerant, utility and packaging item; disclose proxies and missing supplier data |
| disclosure | Declare component supply state, in-house versus purchased operations, configuration, refrigerant species and charge, test boundary, rejected units, packaging state, geography, year and exclusions |

| rule_id | Applies to | Rule | source_ids |

| `sb_factory_gate` | core product system | Include final assembly, wiring, firmware loading when performed at the site, acceptance testing, conditional refrigerant charging and dispatch packaging up to factory-gate readiness. | `ec-jrc-eup-lot12-2007` |
| `sb_refrigerated_route` | refrigerated and combination configurations | Include condensing equipment, declared refrigerant input and species-specific charging loss only when the machine contains that refrigeration route; disclose compartment temperatures and energy-test method. | `eu-2019-2024-direct-sales-refrigeration`; `us-epa-energy-star-vending-v4-2019` |
| `sb_downstream_modules` | distribution, use, maintenance and end-of-life | Exclude these stages from the core factory-gate result. If added, report them as separate modules with service life, vendible capacity, operating mode, daily energy, refrigerant leakage, repair and recovery assumptions. | `eu-2019-2024-direct-sales-refrigeration` |

| `vr_reference_identity` | reference flow | Confirm the output UUID is the complete CPC 43934 machine, not a cabinet, frame or machinery part, and confirm the reference amount equals the declared model's measured net mass. | `un-cpc-3-0-structure-2025` |
| `vr_atomic_inventory` | every inventory row | Reject collection labels and combined utilities, components, refrigerants, wastes or emissions; each row must identify one physical exchange and one applicable property/unit. |  |
| `vr_component_completeness` | purchased assemblies | Reconcile the cabinet, condensing unit when applicable, motors, board, display, dispensing mechanism and payment module to the model bill of material; disclose additional material components rather than hiding them in a combined row. | `ec-jrc-eup-lot12-2007` |
| `vr_energy` | `assembly_electricity` | Verify meter boundary, kWh-to-MJ conversion, model-specific allocation and exclusion of use-phase electricity. | `eu-2019-2024-direct-sales-refrigeration` |
| `vr_refrigerant_route` | refrigerant inputs and outputs | Require exactly the declared refrigerant species rows for each refrigerated model, reconcile charge and loss, and reject a combined refrigerant row or an emission assigned to the wrong air compartment. | `us-epa-energy-star-vending-v4-2019` |
| `vr_bilingual_uuid` | UUID-bearing rows | Confirm English and Chinese use the same UUID and that Chinese uses the direct-read TianGong baseName; for HFC-134a retain the English baseName because TianGong provides no Chinese baseName. |  |
| `vr_range_evidence` | amount ranges | Reject an externally inferred range unless at least two independent original sources have compatible boundary, functional unit and product state; specification limits are not empirical ranges. |  |
| `vr_boundary_disclosure` | dataset profile | Confirm the core result ends at factory-gate readiness and that any distribution, use, maintenance or end-of-life scenario is a separate disclosed module. | `eu-2019-2024-direct-sales-refrigeration` |

## 10. Published Dataset Profile

| Field | Value |
| --- | --- |
| dataset_role | Product-specific factory-gate secondary dataset derived from verified foreground production records |
| downstream_use | Background dataset for manufacture of the declared automatic goods vending machine; input to separately parameterized distribution, use, maintenance and end-of-life lifecycle models |
| allowed_use | Comparisons within the same complete-machine scope, model configuration, reference mass, geography, year, allocation rule and packaging boundary; scenario modelling with separately disclosed downstream modules |
| excluded_use | Generic use-energy claims; attribution to rebuilt machines or parts; comparison of unlike dispensing, capacity or temperature functions without normalization; substitution for supplier component data when supply state differs |
| required_metadata | PCR id and version; model and configuration; geography and year; net and packaged mass; vendible capacity; dispensing and payment technology; temperature function; voltage/frequency; test energy; refrigerant and charge; design life; upstream dataset list; allocation; exclusions; data owner |
| required_quality_disclosure | primary-data coverage; meter and scale calibration; model/batch reconciliation; supplier-data share; proxies; refrigerant balance; rejected units; missing ranges; uncertainty and reviewer status |
| update_trigger | model or bill-of-material revision; new dispensing/payment/refrigeration technology; refrigerant substitution; more than 10% change in net mass, manufacturing electricity or major component mass; supplier geography change; packaging change; new reviewed UUID; or new independent range evidence |
