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.

When constructing a foreground data package, the items listed in Required qualifiers must be declared in dataset metadata, process notes, reference flow comment, product description, or an equivalent data package field. Missing required qualifiers make the reference flow definition incomplete for that data package.

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.
