Self-propelled bulldozers and angledozers

1. Scope and Applicability

This candidate governs new complete self-propelled dozers delivered at the factory gate, including the actual host, running gear and shipped blade configuration. Crawler and wheel machines qualify only when their actual primary product is a dozer; a loader carrying a temporary blade, agricultural tractor, grader, scraper, excavator, separately sold blade or replacement part does not qualify merely through an attachment. Later earthmoving service, moved soil, operation fuel, maintenance and end-of-life are separate. Sources: un-cpc3-dozers; cat-d6xe; komatsu-d61; shantui-de17.

OEM examples establish different architectures: Komatsu documents diesel/hydrostatic crawler drive and factory control equipment; Caterpillar D6 XE combines diesel engine with electric traction; Shantui DE17-X documents LFP battery, electric motors/controllers, thermal management and crawler dimensions. Electric-drive wording alone never removes a diesel engine or proves a traction battery. Actual battery hybrid routes retain both installed systems and measured charging/fuel. Shantui narrative and specification battery-energy figures differ: no listed capacity, marketing savings, operating mass or runtime becomes an inventory factor. Caterpillar 824 confirms a wheel-dozer diesel powershift alternative, with torque converter and actual brake/axle equipment. Track/wheel route, blade geometry, arms, cylinders and optional control packages follow actual shipped BOM.

Cards represent conditional single exchanges, not a fixed recipe. Actual cutting gases, filler grades, heat treatment/quench fluids, coating chemistries, batteries, tyres, refrigeration species, bought hydraulic blocks, bearings, brakes and ripper/winch options must each have their own concrete exchange when present. Document absence as not_applicable, never convert unknown into zero or omit a real route because its UUID is unresolved. Thermal treatment, machining and coating occur only in actual foreground work; supplier-completed operations remain upstream.

7. Allocation and Co-product Handling

rule_id	Rule	source_ids
allocation_separate	First separate by configuration work orders and submeters; allocate shared demand by measured causal drivers. Rated host power, blade capacity and moved-soil quantity do not substitute for factory measurements.
allocation_losses	Retain reject/rework, production scrap and captured-waste burdens; accepted denominator excludes rejects, packaging and unmatched configurations. Link wastes to actual providers; no default avoided virgin material credit.

MJ for energy; kg for mass	per batch and meter interval	same production period	same factory/delivered configuration	attributable exchange amount / accepted machines	measurements, sampling, stocks, allocation, supply and uncertainty
cp_shared	shared	atomic_exchanges	production_record	exchange identity; Q; N; configuration; period; meter units; opening/closing stock; own assay; wet/dry basis; provider; route	Meters, calibrated weighing, procurement, work orders, sampling and provider records; include reject/rework, separate test fuel/charging and retained fill.	MJ for energy; kg for mass	per batch and meter interval	same production period	same factory/delivered configuration	attributable exchange amount / accepted machines	measurements, sampling, stocks, allocation, supply 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 crawler/wheel 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

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

9. Validation Rules

rule_id	Rule	source_ids
validate_configuration	Confirm self-propelled dozer semantics, crawler/wheel and propulsion architecture; reference/inventory share shipped BOM; separate sold blades and later use.	un-cpc3-dozers; cat-d6xe; komatsu-d61; shantui-de17
validate_measurement	Require positive accepted count/mass, finite exchanges and explicit conversion; verify rework/loss, term-specific water/species balances, shared residual and actual uncertainty.
validate_identity	Adopt UUIDs only with direct type, official bilingual name, reference property/unit, state/supply interface and geography confirmation; disclose unresolved identities/ranges for prepublication review.

rule_id	Rule	source_ids
validate_denominator	For each configuration/period Q retains reject/rework burden, N is accepted count, D is sum of calibrated accepted net masses, M = D/N, q_item = Q/N and q_ref = Q/D; denominator excludes packaging/rejects/other configurations and stocks/WIP use the same period.
validate_utility_residual	Same period/units: imports plus actual on-site generation minus exports/storage change equal assigned fabrication/treatment/assembly/test/dispatch plus unassigned residual and conversion losses; shared rows allocate only residual. Never add site meter to submeters; investigate negative residual/calibration/combined uncertainty without clipping.
validate_charging_balance	Test charging reconciles imported energy, recuperated/exported energy, storage change and actual conversion losses. Diesel-electric is not battery-electric; capacity/rated charging power cannot replace meters; internal transfers cancel and on-site generation fuel/emissions count once.
validate_water_closure	Actual input moisture and dilution/cleaning/coolant water reconcile with product/fluid retention, wet scrap/sludge water, wastewater, evaporation and stocks, adjusted for reaction water production/consumption; paired returns cancel, each term uses its own water content and differences are investigated against actual combined sampling/measurement uncertainty.
validate_contained_species	For each metal/species apply each term’s own measured assay, concentration and wet/dry conversion to its own amount for input/product/scrap/slag/dust/sludge/wastewater/releases/stocks, including reactions changing species; gross mass is not element mass. No universal tolerance.
validate_solvent_combustion	Solvent supply reconciles retention/recovery/capture-media/stocks/actual destruction/non-air residual before confirming species air release. Actual fuel carbon closure cannot establish CO or NOx; each requires species test measurement or applicable evidenced factor and declared species convention.
validate_foreground_route	OEM equipment establishes architecture options, not factory grades or manufacturing recipes. Make/buy, each grade, cut/weld/thermal/coating route and actual test need work orders, certificates, SDS, supplier and foreground measurement evidence; not_applicable is distinct from unknown/zero.
