Manufacture of off-highway dumpers

1. Scope and Applicability

This rule covers new complete off-highway dumpers at the factory gate: actual rigid-frame trucks, articulated haulers and compact site dumpers with installed dump body, tipping system and shipped configuration. An off-road chassis or operating location alone does not establish principal product identity; road freight trucks, water/fuel-service trucks, tractors, separately sold bodies, dumper trailers and replacement parts need separate principal-function review. Later ore/site hauling service, payload, operation fuel, maintenance and end-of-life are outside factory manufacture.

The Volvo A40 original documents diesel engine, torque converter/powershift drive, high-strength welded frame, HB450 body plate and hydraulic tipping; the body material does not establish frame grade. Cat 777F supplies a rigid mild-steel frame with incorporated castings/forgings and contrasting body/liner systems; these do not establish in-house foundry ownership. Wacker DW15e supplies counterevidence to a diesel-only boundary: compact electric dumper with separate drive/hydraulic motors, battery, onboard charger and braking recovery. Actual diesel-electric or hybrid machines retain both installed engine and electric systems; electronic control alone does not prove traction battery. These examples support configurations, not universal mass, thickness, manufacturing energy, yield, lifetime or emissions factors. Missing UUID cannot exclude an electric route.

Declare these qualifiers in the foreground data package; missing qualifiers make its reference flow incomplete.

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.
material_basis	physical material and species records	Mass	kg	Each material/species term uses its own assay and wet/dry basis; gross metal mass is not contained iron or another species.
energy_basis	electricity and fuels	Net calorific value	MJ	1 kWh = 3.6 MJ; fuels need actual heating value; rated power is not factory electricity.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Actual supplier-completed materials/components entering factory
starting_condition_role	foreground_input
product_classification_scope	Complete off-highway dumper and actual shipped body/systems
recursive_input_rule	Bought same-category machine/host enters upstream once; disclose assembly/conversion/rework and do not recreate embedded manufacture
upstream_dataset_requirement	Match actual grade, module boundary, state, supply interface, geography/year; disclose gaps
disclosure	Per-component make/buy matrix, actual body/tyres, propulsion/battery, fluids, tests and packaging

rule_id	Rule	source_ids
boundary_factory	Include receiving, actual manufacture/assembly, upstream purchases, factory tests/rework and packaging; later hauling service separate.	volvo-a40-2025; wacker-dw15e; cat-777f
boundary_make_buy	Reconcile each frame/body, engine, transmission, axle, pump/cylinder, motor, battery, tyre and cab make/buy. Completed purchases include embedded materials, fluids and operations upstream once. In-house manufacture records actual separate grade/chemistry inputs and operations; paired internal transfers cancel.	volvo-a40-2025; wacker-dw15e; cat-777f

6. Process Inventory Structure

Process Map

process_id	process_name	inclusion	inclusion_condition	role	quantitative_reference
fabrication	Frame and dump-body fabrication	conditional	Actual in-house cutting, forming, machining and welding; supplier-completed assemblies remain upstream.	foreground	1 kg reference flow
surface	Surface and thermal treatment	conditional	Actual work-order treatment; no assumed universal paint or heat treatment.	foreground	1 kg reference flow
assembly	Architecture-specific dumper assembly	required	Actual rigid/articulated/compact propulsion, steering, tipping and delivered configuration.	foreground	1 kg reference flow
test_pack	Factory acceptance, first fill and dispatch	required	Factory acceptance only, including actual test fuel or charging.	foreground	1 kg reference flow
shared	Unassigned shared services	conditional	Only measured attributable residual after process assignments.	foreground	1 kg reference flow

Cards are conditional atomic exchanges, not a recipe. Actual in-house casting, forging, heat treatment, powder/waterborne coating, tyre, motor or battery manufacture requires work-order branches with separate concrete alloy grades, resin, coating, solvent, electrolyte, copper conductor, magnet, casing, refrigerant, fuels and each waste/emission. Never count a completed purchased module together with its embedded material inputs. The example battery pack does not narrow the category; other actual chemistries/supplied models require explicit identity. Distinguish not_applicable, unknown, missing and zero; UUID gaps cannot remove real routes.

cp_purchased_heat	shared	purchased_heat	meter_record	supply mass; return mass; own enthalpies; common datum; pressure; temperature; dryness; heat meter; gross/net provider interface; period; configuration; N	Steam/condensate meters, calibrated mass or heat meters; supplier contract confirms gross versus net heat scope; exclude own-boiler internal supply.	MJ	per meter interval	same production period	actual supply and return boundary	attributable net steam heat / accepted machines	meter calibration, thermal state, common datum, supplier contract and uncertainty

For one configuration and common production period, Q is each attributable period exchange including reject/rework burden, N is accepted units, D is sum of calibrated accepted net masses, M = D/N and q_item = Q/N. Applying normalize_mass gives q_ref = Q/D. Reconcile stocks/work in progress and retained fluids to that configuration; exclude packaging and rejected mass from D. Do not average different rigid/articulated/compact or propulsion configurations or use nominal operating weight.

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 machine; q_ref = exchange amount per 1 kg reference flow.	q_item; M; cp_mass	q_ref
purchased_heat	steam	Net steam heat = supply mass × supply specific enthalpy − return mass × return specific enthalpy; independently measure both masses and use actual pressure/temperature or dryness with one enthalpy datum, or a calibrated net heat meter. Declare gross-delivered versus net-heat provider interface first, never purchase both; count condensate once in water closure and exclude own-boiler internal steam.	cp_purchased_heat	net supplied heat / MJ
utility_closure	site utility records	Same-period/unit imports plus actual on-site output minus exports and storage change equal assigned fabrication, treatment, assembly, test/dispatch demand plus unassigned residual and actual conversion losses. Shared rows allocate residual only. Investigate negative residual against periods, units, meter calibration and actual combined measurement/sampling/allocation uncertainty without clipping; paired internal transfers cancel and generation is not also purchased.	cp_fabrication; cp_surface; cp_assembly; cp_test_pack; cp_shared	same-period utility closure
water_closure	physical water records	Each input moisture and dilution/cleaning/cooling water plus actual reaction water production minus reaction consumption equal product/fluid retained water, scrap/sludge water, wastewater, evaporation and water stock change. Each term uses its own water assay and wet/dry conversion; paired internal returns cancel. Investigate difference against actual combined measurement/sampling/allocation uncertainty, with no universal tolerance.	cp_fabrication; cp_surface; cp_assembly; cp_test_pack; cp_shared	actual water closure
contained_species_closure	physical material and species records	For each actual metal/species, each input own mass times own assay plus reaction generation minus reaction consumption equals each product, scrap, slag, dust, sludge, wastewater, release and stock-change own mass times own assay. Each term uses its own sampling, moisture and wet/dry basis; internal transfers cancel, gross mass is not contained-element mass, and investigate with actual combined uncertainty.	cp_fabrication; cp_surface; cp_assembly; cp_test_pack; cp_shared	actual species closure
solvent_closure	actual solvent records	Reconcile paint-embedded and added solvent, product retention, recovery, capture media, stock change, actual destruction and non-air residual separately; capture is not destruction and unexplained residual cannot be assigned to air. Species air release requires measurement or applicable evidence; fuel carbon closure cannot replace CO or NOx species measurement.	cp_surface; cp_test_pack	reconciled species destinations

Reconcile site utilities in the same period and units: imports plus actual on-site generation minus exports and storage changes equal already assigned fabrication, treatment, assembly, test/dispatch demand plus unassigned residual and evidenced conversion losses. Shared rows carry only measured causally allocated residual. Never add site totals to submeters; investigate negative residual using period/unit alignment, calibration and combined allocation uncertainty, never clip to zero. On-site generation records fuel/water/species once; paired internal power transfers cancel and are not also purchased electricity. Test charging records imported energy, recuperated/exported energy and storage change, not battery capacity or rated charger power.

Close water using each actual input moisture, dilution/cleaning/coolant water, retained product/fluid water, wet scrap/sludge, wastewater, evaporation, stocks and actual reaction production/consumption. Paired internal returns cancel within the boundary. Close each contained metal/species using each term’s own measured assay, concentration, wet/dry conversion and amount for inputs, accepted product, scrap, slag, captured dust, sludge, wastewater, releases and stocks; include reactions changing species. Gross material mass never equals contained element. Investigate differences using actual combined measurement, sampling and allocation uncertainty; no universal tolerance, yield or invented balance coefficient.

For each actual solvent, distinguish paint-embedded and added solvent, retained product, recovered solvent, capture media, stocks, actual destruction and non-air residuals before calculating a measured species-specific air release. For test combustion, actual fuel carbon and all carbon outputs constrain carbon closure but cannot establish CO or NOx; those require species-specific test measurements or an applicable evidenced factor and declared species convention. Refrigerant leaks, uncaptured metal aerosols and other emissions, if present, need separate species/compartment records and matching evidence.

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
quality_config	reference and inventory	Same actual configuration, shipped scope, acceptance period/net mass; real make/buy and supply interfaces.	shipped BOM, calibrated weighing, work orders and supply records
quality_gaps	each exchange	Row-specific collected/calculated/not_applicable/unknown/missing status; disclose UUID/range/source gaps; unknown is not zero.	route matrix, identity review, sampling and uncertainty

Purchased steam and condensate returns use one enthalpy datum, actual pressure/temperature or dryness and measured masses; net heat equals imported mass times supply enthalpy minus returned mass times return enthalpy. Count returned water once in water closure; paired internal steam loops cancel and are not purchased steam. Add atomic rows for each actual additional fuel, refrigerant/chemical and emitted species, measured for the same factory period.

9. Validation Rules

rule_id	Rule	source_ids
validate_configuration	Confirm rigid/articulated/compact dumper principal function, shipped body and propulsion; road freight or water service does not match merely through chassis.	volvo-a40-2025; wacker-dw15e; cat-777f
validate_measurement	For same configuration/period Q includes reject/rework burden, N accepted units, D summed calibrated accepted net mass, M = D/N, q_item = Q/N and q_ref = Q/D; exclude packaging, payload and rejected mass.
validate_utility	Reconcile same-period/unit imports, actual generation, exports/storage changes with assigned demand, residual and actual losses; no additive site-meter double count. Investigate negative residual against calibration/sampling/allocation uncertainty without clipping. Test charging reconciles imports, recovery/exports and storage changes.
validate_water_species	Each physical/species balance term uses its own moisture/assay and wet/dry basis for input, product, scrap, sludge, wastewater, releases, stocks and reactions; paired returns cancel. Explain closure against actual combined uncertainty; gross mass is not contained element and no universal tolerance applies.
validate_solvent	Distinguish solvent retention, recovery, capture media, stocks, actual destruction and non-air residual; capture is not destruction and residual is not air release. Carbon closure cannot determine CO/NOx; require species test or applicable evidence.
validate_identity	Adopt UUID only after direct type, official bilingual name, reference property/unit, state and supply/geography interface match; avoid module/embedded-input duplication. Disclose missing UUID, formulation, factory or range evidence rather than zero; review publication after actual foreground completion.
