Milking machines

1. Scope and Applicability

This rule covers production of one accepted, complete vacuum and pulsation milking machine at the factory gate, including declared fitted milking assemblies. Bucket, pipeline and recorder configurations are included when their bill of materials and acceptance record identify the delivered configuration. It excludes dairy processing and cooling machinery, loose replacement parts, installation services, operation on farm, cleaning during use, and end of life. The foreground inventory covers attributed component preparation, assembly and acceptance testing; supplied components carry linked upstream datasets. The boundary is grounded in un-cpc-3-2025 and equipment architecture in fao-milking-machine.

Required qualifiers	model; configuration; vacuum and pulsation arrangement; included milk-contact assembly; accepted net mass M; factory-gate state

When constructing a foreground data package, the required qualifiers must be declared in the dataset or equivalent process notes.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_mass	reference product	Mass	kg	M = accepted net mass of one complete machine of the same configuration in kg; collect using cp_mass.

5. System Boundary

Include attributable incoming supplied components and materials, factory electricity, outgoing accepted machines and separately recorded production waste. Upstream burdens of supplied flows are linked through datasets, with no recursive recreation of this product category. Exclude use, farm installation and disposal unless a separate study extends the boundary.

Boundary Abstraction

Field	Value
declared_starting_condition	Factory receipt of purchased components and raw sheet, with supplier state and on-site fabrication route declared
starting_condition_role	Foreground start for manufacturing records
product_classification_scope	Complete milking machines; CPC 3.0 44131 is classification context only
recursive_input_rule	If an incoming complete milking machine is used, record it as an upstream product input and disclose its source dataset rather than recursively reclassifying it as new output
upstream_dataset_requirement	Link upstream datasets for each purchased component and material with documented geography and technology
disclosure	Disclose configuration, purchased versus fabricated components, missing component records, test energy, waste route and factory-gate cut-off
