# Complete diesel rear-loading refuse compactor road vehicle manufacturing

## 1. Scope and Applicability

Manufacture of complete new diesel single-chamber rear-loading refuse compactor road vehicles, with a purchased runnable cab-chassis, fabricated steel body/subframe and hydraulic packing/discharge equipment integrated and accepted by the vehicle converter. Declare one exact VIN/model and released body/chassis configuration. This is a narrower product and manufacturing-route boundary within CPC49119, not every special-purpose vehicle.

Exclude body-only, chassis-only, rebuilt/remanufactured vehicles, multi-chamber and side/front-load architectures, electric/CNG propulsion, street sweepers, fire engines, mobile cranes, concrete mixers, ambulances and ordinary goods vehicles. Waste collection/transport/treatment service, transported waste mass, driver/crew/payload, operation, maintenance, distribution and end-of-life are outside scope. Factory functional/road tests and rework are manufacturing. No service life, collection yield or waste-throughput denominator is assumed.

## 3. Reference Flow

| Field | Value |
| --- | --- |
| What | Manufacture and factory acceptance of one declared complete diesel rear-loader refuse compactor vehicle. |
| How much | 1 kg accepted net complete vehicle, normalized from one complete unit by measured M; not one kilogram of carried refuse or a collection service. |
| How well | Conform to actual released drawings/BOM, chassis/body interface and model-specific structural, hydraulic, control/interlock and road-release acceptance. Retain actual approval/test identifiers where held; no universal test pressure, compaction ratio, cycle duration or certification inherited. |
| How long or cycle | One manufacture/acceptance cycle; operational distance, collection capacity and life outside reference basis. |

The category product identity is restricted by all required qualifiers to the complete manufactured rear-loader configuration; it supplies neither a generic vehicle average nor numerical upstream LCI. Missing qualifiers make the foreground data package incomplete.

## 4. Measurement and Unit Rules

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |
| reference_mass | reference product | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | M = accepted net mass of one complete unit of the same configuration in kg; collect using cp_mass. |
| electricity_units | body_electricity; coating_electricity; integration_electricity; release_electricity | Net calorific value `93a60a56-a3c8-11da-a746-0800200c9a66` | MJ | Convert measured meter kWh to MJ using3.6 MJ/kWh; preserve actual voltage/provider. Mechanical PTO demand is supplied by test fuel, not an additional electric input. |

Weigh the same accepted complete fitted vehicle on a calibrated vehicle scale: empty hopper/body, no crew, cargo or temporary test ballast, exclude shipment protection and detached spares. A separate VIN-bound delivery-state record declares retained hydraulic oil, fuel and chassis coolant/lubricants, installed accessory/spare status, gross readings and tare exclusions. Recoverable test fills are excluded when not delivered. Catalogue curb weight, GVW, axle limit or approximate body weight cannot replace M. Purchased count-based parts may retain their original count identity with traceable actual part mass and explicit conversion; never relabel a public count/area/volume property Mass.

## 5. System Boundary

### Boundary Abstraction

| Field | Value |
| --- | --- |
| declared_starting_condition | Converter receives runnable diesel cab-chassis, steel stock and released purchased hydraulic/electronic components. Chassis manufacture/steel rolling/component manufacture occur upstream unless explicitly added as separate site modules. |
| starting_condition_role | Declared vehicle conversion/manufacturing foreground starting point. |
| product_classification_scope | Manufacture of complete new diesel single-chamber rear-loading refuse compactor road vehicles, with a purchased runnable cab-chassis, fabricated steel body/subframe and hydraulic packing/discharge equipment integrated and accepted by the vehicle converter. Declare one exact VIN/model and released body/chassis configuration. This is a narrower product and manufacturing-route boundary within CPC49119, not every special-purpose vehicle. |
| recursive_input_rule | Purchased complete refuse vehicle is not a component proxy. Purchased painted body, chassis or hydraulic subassembly replaces its contained local materials/work. Internal fabrication handoffs are transfers. Separate supplier-contained from additionally fitted components and fluids. |
| upstream_dataset_requirement | Expanded assessment needs actual compatible chassis/steel/chemical/component supplier LCI, outsourced work, inbound/intersite transport, utilities and external treatment. UUID confirms identity, not inventory amount/provider. This foreground module alone is not complete cradle-to-gate. |
| disclosure | Declare sites/period, body/chassis make-or-buy, variants, installed versus detached supply, received/delivered fluid state, acceptance/rework, utility carriers and provider/transport/treatment gaps. |

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| boundary_body | body | Heil case supports a steel body and welded formed-channel subframe; actual released drawings govern fabrication, coatings and wear grade. No brochure steel thickness or universal manufacturing recipe prescribed. | heil-durapack-5000-2025 |
| boundary_interface | integration | Heil hydraulic/chassis tables and Dennis Eagle body variants establish component/interface specificity. Scania historical attachment alternatives require current model-specific mounting evidence; they do not approve this installation or mandate bolt/weld combinations. | heil-durapack-5000-2025; dennis-eagle-olympus; scania-chassis-subframe |
| boundary_service | release | Include actual factory fuel use, leak/packing/road tests and recovery; exclude waste collection/processing and routine operating loads. Test payload must be identified and removed before M measurement. |  |

## 6. Process Inventory Structure

### Process Map

| process_id | process_name | inclusion | inclusion_condition | role | quantitative_reference |
| --- | --- | --- | --- | --- | --- |
| body | Steel body and subframe fabrication | required | Actual cut/form/join steel route, hopper, packer panels, ejector and tailgate structures. Purchased completed modules replace their contained site materials/work. | foreground_production | per 1 kg reference flow |
| coating | Body corrosion protection and coating | required | Actual released finish or disclosed supplied finished body; cleaning/primer/topcoat/electric cure are conditional site operations, not required universal chemistry. | foreground_production | per 1 kg reference flow |
| integration | Chassis mounting and hydraulic/control integration | required | Receive complete runnable diesel cab-chassis; mount exact body/subframe, install hydraulic actuation, controls and actual optional lifter. Document interface approvals and contained supplier scope. | foreground_production | per 1 kg reference flow |
| release | Commissioning, acceptance and weighing | required | Actual leak/pressure/packing/ejection, interlock/emergency stop, road/brake and model-specific tests; record measured fuel/utilities/recovery and accepted complete vehicle M. | foreground_production | per 1 kg reference flow |
| packing | Shipment protection | conditional | Only actual separately quantified shipment protection, outside vehicle M; detached spares separately disclosed. | foreground_production | per 1 kg reference flow |

These are single-exchange candidates, not a universal complete BOM. Complete each actual released route: add every separately supplied hinge/pin/bearing/seal/filter/fitting/bracket/nut/washer, packer panel, cylinder design, pipe, display/switch/sensor/lamp/camera, lift assembly and coating ingredient not contained in another purchase. Required processes remain required while chemical/technology candidates are conditional. Add actual machining/blasting/heat treatment and their exact abrasive, lubricant, utility and waste flows when performed. Document outsourcing and all factory emissions/wastes; captured welding dust is separate from air particulate.

## 7. Allocation and Co-product Handling

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| allocation_demand | shared_operations | Subdivide by site/configuration/work order first. Shared cutting/welding, coating, crane handling and test demand use measured causal load/time or attributable exchange from cp_allocation, reconciled to total meter and excluded work. No default mass, GVW, body-volume or refuse-throughput allocation. |  |
| allocation_variants | variants | Keep body size, chassis, actuation, coatings and lifter variants separate; normalize each by its measured M. Any residual physical/economic fallback requires actual supporting records, sensitivity and review. Scrap/reject/rework burdens remain with accepted production. |  |
| allocation_recovery | outputs | Internal steel/paint/water/oil recovery is a transfer; no automatic avoided-production or recycling credit. External scrap and waste treatment recorded explicitly. Marketable coproduct claims require actual quality, quantity and independently reviewed treatment. |  |

### Calculation Rules

| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
| --- | --- | --- | --- | --- | --- |
| normalize_mass | body_sheet; wear_plate; subframe_channel; welding_wire; argon; body_electricity; steel_scrap; weld_pm; wash_water; sodium_hydroxide; epoxy_primer; pu_topcoat; coating_electricity; wash_effluent; paint_waste; xylene_air; cab_chassis; hydraulic_pump; packing_cylinder; tailgate_cylinder; ejector_cylinder; spool_valve; hydraulic_hose; oil_reservoir; pto; steel_screw; body_controller; body_harness; hydraulic_oil; used_oil; integration_electricity; bin_lifter; diesel_fuel; test_water; release_electricity; fossil_co2_air; pe_film; corrugated_board | q_ref = q_item / M; q_item = exchange amount per one accepted finished unit; q_ref = exchange amount per 1 kg reference flow. | q_item; M; cp_mass | q_ref |  |

q_item is the same-period/configuration attributable net exchange divided by accepted complete units, after stock/reject/rework reconciliation. Divide by measured M, keeping each numerator in kg or MJ. If supplier counts or liquid volumes are used for mass, retain actual part-specific weighing or same-formulation measured density/temperature evidence and explicit conversion records; no default part mass/density. Received fuel contained in chassis, new fuel supply, consumed test fuel and retained delivery fuel must reconcile without counting contained supply twice. Compatible variants may be aggregated only after separate normalization with disclosed measured weights and uncertainty.

### Data Quality Requirements

| requirement_id | Applies to | Requirement | Evidence |
| --- | --- | --- | --- |
| quality_identity | flows | Verify exact material grade/state, supplied formulation and component completeness; distinguish chassis/body/service, parts/complete cylinders and commodity oil/formulated fluid. Preserve public reference properties. | released supplier specifications; identity/property/unit audit |
| quality_complete | vehicle | Reconcile fitted components and delivered retained fluids to actual complete M. No invented residual mass, assumed body weight or invisible chassis emissions. Document upstream/treatment coverage gaps. | VIN BOM; calibrated scale; supplier scope; stock closure |
| quality_acceptance | release | Retain actual mounting, leak/pressure, packing/ejector, interlock/emergency-stop, road/brake and applicable release results; no brochure values as acceptance defaults. | signed tests and release; calibrated instruments; actual approvals |
| quality_period | records | Declare sites/representative period, supplier versions, primary coverage, allocation uncertainty and missing/excluded/not-applicable status. Historical interface examples are not current numerical plant data. | work orders; meter closure; sampling conditions; uncertainty |

## 9. Validation Rules

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| validation_reference | finished_machine | Require1kg complete reference output and measured cp_mass M linked to exact empty-body VIN/BOM and delivered fluid/accessory state. GVW, approximate body mass, refuse tonnes or service distance cannot be the denominator. |  |
| validation_basis | inventory | Every applicable non-reference row applies normalize_mass and its declared collection protocol, with the same accepted count/period/configuration. Validate numerator units and original reference properties. |  |
| validation_supply | components | Purchased chassis, painted body, cylinders, lifter and PTO scopes must remove duplicate contained steel/consumables/fluids/components. Separate conditional exchanges from necessary processes; absent candidates require supported not-applicable records. |  |
| validation_emissions | elementary | Require evidence of actual post-control particle size/air medium, xylene speciation and immediate fossil CO2 versus biogenic/retained carbon. Captured dust/treatment liquid are wastes. Add each actual NO, NO2, N2O, CO and other evidenced species separately; NOx totals establish neither NO2 nor NO amount. No default exhaust or leakage. |  |
| validation_coverage | dataset | Distinguish measured/calculated/estimated/missing/excluded/not-applicable. Report unresolved identities/amounts/providers and omitted route coverage. Structural pass does not approve methodology or establish complete cradle-to-gate. |  |
