Hardwall touring caravan trailer manufacture

1. Scope and Applicability

This candidate PCR covers manufacture of new complete hardwall drawbar-towed touring caravan trailers with declared fixed habitation, narrower than CPC3.0 49222. Exclude fifth-wheel semi-trailers, self-propelled motorhomes/campervans, tent/pop-up trailers, static buildings, cargo/utility/agricultural trailers, separately traded chassis/body/spares and refurbishment. Each actual chassis, panel, berth, plumbing/appliance/battery option configuration is modelled separately. Include actual site fabrication, body-panel bonding, cabinetry, shell/rolling-gear assembly, fixed fit-out, factory trials and attributable rework/wastes. Exclude towing vehicle production/use, road travel, campsite occupancy, customer utilities and maintenance, assumed service life and disposal. No accommodation-night or towing-distance functional unit is supplied. Throughout the PCR one accepted finished unit means one complete configured trailer, with Chinese 设备 carrying the same meaning.

Reference unit group	Units of mass 93a60a57-a4c8-11da-a746-0800200c9a66
Reference unit	kg
Required qualifiers	model/serial/batch; drawbar/hardwall status; axle count, chassis/coating/coupling/brake supplier gates; shell skin/core/frame/bond/floor composition and geometry; berth layout and actual installed furniture/bedding; plumbing/appliances, battery and options; supplier module inclusions; retained service fluids; clean empty state, tank/heater drainage and no LPG bottle/fuel; measured M; actual factory/site/period/route/test and protective delivery scope

Weigh the same complete accepted clean empty unit on calibrated scales. Installed habitation, actual installed battery and accessories and declared retained service fluids are included; persons, towing vehicle, payload, loose camping equipment, LPG bottle/fuel, handling fixtures and shipping protection are excluded. Water and heater tanks are drained after factory testing. Catalogue MRO, MTPLM, personal-effects or battery/LPG allowances are not M; brochure empty-state and loose-item boundaries differ. Kilogram normalization does not establish equal berth capacity, towing performance or accommodation comfort. The broad public finished-product name is narrowed by these qualifiers and does not admit semi-trailers or other excluded variants.

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.
energy_units	electricity rows	Net calorific value 93a60a56-a3c8-11da-a746-0800200c9a66	MJ	Preserve the meter unit; convert kWh to MJ using exactly 1 kWh = 3.6 MJ. Do not interpret the electricity property name as a combustion inventory.
volume_units	groundwater rows	Volume 93a60a56-a3c8-22da-a746-0800200c9a66	m3	Retain measured volume and its conditions; do not invent gas density, water density or calorific value to switch to mass or energy.

rule_id	Applies to	Required property	Required unit	Rule
tyre_count_units	tyre	Number of items 01846770-4cfe-4a25-8ad9-919d8d378345	Item(s)	Count actual installed compatible trailer tyres per accepted unit through cp_assembly. Retain the public count reference property and normalize q_item/M to Item(s) per kg of trailer. Separately measured tyre mass supports physical mass reconciliation only, not a public-property rewrite.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Materials and configured components received at declared supplier gates, with no implicit upstream steelmaking or component fabrication in foreground
starting_condition_role	Manufacturing input boundary for an accepted complete unit
product_classification_scope	Complete hardwall drawbar touring caravan trailers within broader CPC49222 context
recursive_input_rule	A purchased complete unit used as an input is a separately declared upstream product. Do not recursively regenerate this category; distinguish new production from refurbishment.
upstream_dataset_requirement	Link input-specific upstream datasets matching material, finished-component gate, geography, voltage and treatment state. Missing links remain disclosed coverage gaps.
disclosure	Report foreground factory stages, outsourced operations, component content, incoming transport coverage, protective packaging gate, capital-equipment policy and every exclusion; no complete cradle-to-gate claim without verified upstream and logistics closure.

rule_id	applies_to	rule	source_ids
manufacturing_gate	foreground	Include every actual operation and attributable rework from declared received inputs through factory acceptance; distinguish purchased parts from site fabrication to prevent duplication. Use documented route records.
conditional_fabrication	fabrication	Activate only documented chassis/panel/furniture fabrication and actual material/adhesive recipes. Manufacturer examples establish possible architecture and alternatives, not universal site routes or formulations.
exclude_customer_camping	camping_service	Exclude towing vehicle, road journeys, customer camping and accommodation service, utilities and maintenance/disposal. Include actual factory trials and their individually identified materials, energy, wastewater and measured emissions; appliance firing occurs only if recorded.

rule_id	applies_to	rule	source_ids
empty_delivery_configuration	reference	Actual fitted battery and installed accessories are included in measured M; catalogue battery allowances are not measurements. Drain water/heater/toilet tanks and exclude LPG cylinder/fuel, loose hook-up leads, steps and camping equipment. Separately supplied items require separate product inventory rather than hidden inclusion in vehicle M. Disassembled delivery requires calibrated component-mass reconciliation to the same complete accepted configuration.

Process records are separate contributors to one final accepted output, not seven separately traded reference products. Retain traceable internal-part transfer and bill-of-material records; internal transfers cancel within this foreground and do not receive duplicated upstream burdens. The cards below are explicit route-conditioned exchanges. Add each actual additional part, chemical, fuel, packaging piece, wastewater stream or measured elementary substance as its own identified row; absence of a card is not a cut-off permission. For outsourced chassis, panel or furniture manufacture, replace corresponding site materials and energy with the exact purchased component or service record and disclose its supplier gate.

7. Allocation and Co-product Handling

rule_id	applies_to	rule	source_ids
direct_attribution	shared_operations	Use job tickets and submetering before allocation. Where a common meter remains, require a measured causal driver such as machine-hours for the identified operation, with all participating jobs and idle load disclosed; divide the attributable quantity by accepted units of the same configuration before mass normalization.	ghg-product-allocation-2011
coproduct_decision	saleable_outputs	Do not assume scrap is a co-product. Disclose destination and legal/product status. If multiple saleable co-products actually occur, seek subdivision; justify a physical relation or, when unavailable, documented economic/other allocation with sensitivity. No universal mass share or avoided-steel credit is prescribed.	ghg-product-allocation-2011
rework_scrap	manufacturing_losses	Retain rework and rejected-unit burdens attributable to the accepted reporting batch. Record recovered internal material once and exported wastes separately. Disclose upstream recycled-content method and any downstream treatment separately to prevent double credits.

Reconcile stage utility totals with the factory bill, and component/retained-fluid inclusion with the net-mass record.	row-specific kg, MJ, m3, Item(s)	each job and meter interval	complete same-configuration batch in reporting period; disclose seasonality and mixed lines	declared factory, outsourced and purchased gates	attributable row amount / accepted units of the same configuration	calibration, supplier composition, job, allocation and disposal evidence

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 unit; q_ref = exchange amount per 1 kg reference flow.	q_item; M; cp_mass	q_ref

The finished_machine output is fixed at 1 kg and is not divided again. Apply the conversion to each other applicable row using the same configuration and batch; quantity numerator units remain unchanged. Mixed configurations must be separated, not averaged by count with a catalogue mass.

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
configuration_trace	all rows	Trace every input to installed BOM, route and accepted unit; supplier finished parts do not also receive raw-stock burdens. Disclose remaining components as missing coverage until separate atomic records are added.	drawings, BOM, supplier receipts
basis_quality	cp_mass	M must be positive measured net mass, with the same delivered configuration, fluid state and acceptance gate as all collected exchanges.	calibration and weighing records
coverage_quality	all processes	Document full batch temporal coverage, meter overlap, rejects, rework, stock changes, outsourced stages and unmeasured emissions. A missing record is unknown, not zero or not_applicable.	ledger, coverage matrix and measurement uncertainty
chemistry_quality	panels; cabinetry; assembly; fitout	Verify recipe, concentration and SDS for each supplied formulated chemical; characterize each outgoing waste stream and identify treatment separately from environmental emissions.	recipe, SDS, analyses and transfer tickets

9. Validation Rules

rule_id	applies_to	rule	source_ids
validate_reference	reference	Reject missing qualifiers, LPG/water/payload-loaded or shipping-gross mass substitution, non-positive M or mismatch between configuration, cp_mass and finished_machine. Require 1 kg output and explicit normalize_mass on every non-reference applicable row.
validate_atomic	inventory	Require one physical exchange per row, verified public identity when supplied, correct property/unit, localized display and medium. Unresolved UUIDs do not authorize proxy substitution or mixed rows.
validate_balance	coverage	Reconcile installed mass, stock, waste, retained fluids and purchased parts using the actual BOM; independently reconcile installed chassis/shell/panel/adhesive/cabinet/appliance/battery content and retained fluids with measured BOM mass; reconcile test water issue, internal reuse and drainage, propane consumption and measured external-air emissions. Reconcile utilities by stage; internal transfers cancel. Explain differences against recorded measurement uncertainty, without a fabricated numerical tolerance.
validate_completeness	dataset	Check every conditional stage against route evidence. Require missing chemicals, parts, test media and actual emissions to be split and collected before claiming a complete inventory; prohibit cradle-to-gate or service comparisons while upstream or functional coverage is incomplete.
validate_allocation	shared_operations	Require complete driver records and justification for allocation and scrap treatment; document sensitivity where another defensible allocation may change results.	ghg-product-allocation-2011
