Pneumatic and other continuous action elevators and conveyors, for goods or materials

1. Scope and Applicability

This PCR applies to cradle-to-gate manufacture of complete general-purpose pneumatic and other continuous-action elevators and conveyors that move bulk materials or unit loads. It covers material preparation, fabrication, route-specific surface finishing, assembly and controls integration, factory acceptance testing, and supplied packing through the manufacturer's factory gate.

The category includes pneumatic conveying systems and continuously operating belt, chain, screw, apron, vibrating, bucket-elevator, overhead, or functionally comparable conveying equipment when sold as complete equipment. Purchased motors, gearboxes, belts, controls, housings, piping, and structural members are inputs to the equipment system, not alternative reference products.

This PCR excludes passenger lifts, escalators and moving walkways; intermittent cranes, hoists, forklifts, and industrial robots; pumps and liquid elevators; conveyor belting sold separately; underground-use conveying equipment designed as a distinct special-purpose product; installation at the customer site; distribution after the factory gate; operation, maintenance, replacement parts, and end-of-life. A study that adds any excluded stage shall report it as a separate module and shall not merge it into the cradle-to-gate result.

It ends when the complete tested product and its separately reported supplied packing leave the factory gate. Upstream production is represented by supplier-specific or otherwise representative upstream datasets linked to each product input.

rule_id	Applies to	Rule	source_ids
al_subdivide	multi_product_manufacturing	Prefer direct metering, work-order records, and process subdivision to assign materials, energy, test media, scrap, and outsourced operations to the declared equipment configuration.
al_physical	residual_shared_inputs	When subdivision is not feasible, allocate shared material-processing and energy inputs using a documented physical driver such as machine time, processed mass, weld length, coating area, or test duration that causally represents consumption.

al_scrap	ferrous_scrap_and_recycling	Report scrap at the point it leaves the foreground process with its measured mass and destination. Do not subtract an avoided-primary-material credit from the foreground inventory; any recycling benefit belongs to a separately declared downstream modelling convention.

dq_performance	factory acceptance testing	Retain declared capacity, route, lift or distance, load or conveyed material, power and control settings, acceptance limits, safety-function checks, deviations, and signed results; for applicable idler belt conveyors, document the capacity and power calculation method.	Signed test procedure and report; ISO 5048:1989 where applicable; ISO 12100:2010 and applicable legal conformity documentation
dq_completeness	all foreground exchanges	Check purchase, waste, environmental, maintenance, and incident records for additional atomic exchanges; quantify or explicitly justify every exclusion and do not use a generic utility, waste, or emission collection label as an inventory row.	Completeness checklist, record reconciliation, and exclusion log

9. Validation Rules

rule_id	Applies to	Rule	source_ids
vr_reference	reference_flow	Confirm the reference product UUID, mass property, mass unit group, exact 1,000 kg normalization, and all required qualifiers; reject packed mass substituted for unpacked equipment mass.	un-cpc-3-0-structure-2025
vr_inventory	process_inventory	Confirm every row is one atomic exchange, each UUID-bearing row matches the declared flow type, property, unit group, and official Chinese name, and every unresolved row appears in manifest review metadata.
vr_mass_balance	material_fabrication_and_packing	Confirm carbon-steel plate, steel scrap, returned stock, installed mass, supplied packing, and reference product are reconciled without an unreported recycling credit.
vr_energy_separation	energy_and_test_media	Confirm electricity, natural gas, and compressed air are separately metered or causally allocated, use their declared properties and units, and are not combined into one utility row.
vr_route	conditional_rows	Confirm each conditional exchange is supported by the declared technology route and production records; do not apply belt, gas-curing, oxygen-cutting, compressed-air, or wooden-crate rows to an absent route.
vr_performance_safety	factory_acceptance_testing	Confirm functional and safety acceptance evidence covers the declared configuration, reasonably foreseeable use, control and stopping functions, safe blockage handling, and declared conveying performance; document deviations and re-tests.	eu-machinery-regulation-2023-1230
vr_disclosure	published_dataset	Confirm required metadata, temporal and site coverage, allocation drivers, upstream dataset links, proxies, cut-offs, outsourced operations, noise and hazardous-substance emission information where applicable, and excluded stages are disclosed.	eu-machinery-regulation-2023-1230

10. Published Dataset Profile

Field	Value
dataset_role	secondary_dataset; may serve as background_dataset after methodology review and publication
downstream_use	Foreground process and lifecycle-model projections for cradle-to-gate manufacture of the declared complete conveying equipment configuration
allowed_use	Comparison or modelling of equipment configurations with equivalent reference mass, factory-gate boundary, functional qualifiers, technology route, geography, time period, data quality, and allocation basis
excluded_use	Direct comparison of conveying service efficiency without matched capacity, route, duty cycle, service life, use-phase energy, maintenance, and end-of-life; passenger lifting, intermittent lifting machinery, pumps, separately sold parts, or underground-only equipment
required_metadata	PCR id and version; equipment model and configuration; conveyor technology; handled material or unit-load specification; rated capacity; conveying length and lift or route profile; duty class; drive, power and controls; included accessories; unpacked mass; surface finish; test scope; design service life; factory geography; reporting period; make-versus-buy boundary; packing; allocation; cut-offs; upstream datasets; unresolved UUIDs
required_quality_disclosure	Primary-data share; meter and scale calibration; temporal and site coverage; sampling; mass-balance closure; causal allocation drivers; supplier-data age; proxy datasets; test conditions and results; rework; exclusions; uncertainty and unresolved evidence needs
update_trigger	Material change in equipment boundary, dominant material or component design, drive or conveying technology, factory route, energy supply, surface treatment, test protocol, packing, geography, allocation method, upstream dataset, or evidence that changes a material inventory result
