Non-electric domestic iron or steel room-heating stoves, grates and braziers

1. Scope and Applicability

This candidate covers complete non-electric domestic iron or steel room-heating stoves, grates, braziers and similar appliances. Preserve solid-fuel, oil and gas architectures, freestanding/inset/open-grate/open-brazier designs and cast iron, fabricated steel or mixed iron/steel construction. One configuration-specific factory package is normalized by accepted net equipment mass; it does not make different heating services functionally equivalent. Scope is not automatically expanded to whole aluminium or ceramic appliances merely because they contain a steel screw or grate.

Exclude cooking appliances and plate warmers, electric heating appliances, central-heating boilers and radiators, industrial furnaces and separately supplied parts. Assess principal function of cook/heater hybrids rather than selecting by appearance or fuel. Non-electric air heaters/hot-air distributors incorporating a motor fan or blower are adjacent CPC44824: an auxiliary-blower design needs actual principal-function review. CPC3.0:44822 is the classification coordinate, not a recipe or evidence that every retained leaf has usable methodology.

Jotul's inspected manufacturing descriptions distinguish own foundry alloy adjustment and sand molding from imported finished castings assembled at another plant, and cover gas/wood stoves and inserts with sheet-metal production. Independent Gazco/Stovax product bodies distinguish steel body/cast door gas appliances with conventional or balanced flues and manual or optional remote controls; steel stove ranges include boiler counterexamples requiring review. Franco Belge's original brochure describes oil room-heaters using kerosene and identifies lining, door rope, glass and grates as conditional parts. The Stovax original manual covers domestic solid-fuel grates and gas inserts and separates installation commissioning from use. These cases show alternatives, not universal BOMs or factory data. AGA/ESSE cooking and cook/heater examples are adjacent counterevidence, not accepted generic room-heater evidence. No catalogue weight, power, efficiency, fuel rate, marketing recycled percentage or warranty is adopted as a factory default. Actual configuration records resolve unshown braziers and unknown materials.

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_species	physical material/species records	Mass	kg	Use each term own moisture/metal/chemical assay, stocks and reactions. Gross mass is not contained element; do not apply to electricity/transport.
energy_interface	electricity, steam, condensate and fuel	Delivered energy or fuel mass and NCV	MJ; kg; MJ/kg	Retain kWh electricity, 1 kWh=3.6 MJ. Steam supply and return each use own kg times own MJ/kg relative to common zero; distinguish gross/already-net, return deducted once. Fuel uses own mass and NCV, not purchased steam.

5. System Boundary

rule_id	Applies to	Rule	source_ids
gate	foreground	Include actual receipt, site fabrication, fuel-specific burner/grate integration, integration, factory test/rework, common services, waste and packing through accepted release.	jotul-manufacture; stovax-stoves
make_buy	supplier_interface	For each component choose its actual make/buy state: complete bought casting/burner/valve/window/lining module includes embedded inputs once; own fabrication uses actual feedstocks and operations instead. Charge only subsequent site work. Pair internal transfers; do not list site-made intermediates as purchased imports.	jotul-manufacture; jotul-cast-iron
factory_use	production	Actual factory fuels, leak-test gases, cleaning water and test electricity are production burdens when consumed; reusable fixtures need stock/reuse records. Separate actual factory burner-test exhaust/ash from household lifetime combustion, chimney/building installation and installer commissioning. The latter are downstream, not manufacturing defaults.	stovax-open-grate
bom_extension	route	Cards are specific conditional anchors, not universal recipes. Audit actual BOM, formulations, test media, packaging, fuels, waste and species. Add each missing atomic actual exchange; document not_applicable only with absence evidence, unknown differs from zero. Unresolved actual lining/coating chemistry retains the relevant architecture and requires a specific matched identity.	franco-oil; gazco-gas
upstream	links	Link supplier production and transport at actual grade, state, delivery geography/voltage and period; external treatment after measured waste transfer is distinct from site emissions. Without completed providers this factory package is not a complete cradle-to-gate result.

Boundary Abstraction

Field	Value
declared_starting_condition	Actual selected inputs supplied grade, completion state and delivery interface
starting_condition_role	Factory foreground receipt boundary
product_classification_scope	Full non-electric domestic iron/steel room-heating category reviewed in section1
recursive_input_rule	Same-category purchased precursor uses upstream once; expand subsequent site work only, cancel paired internal transfers without infinite recursion
upstream_dataset_requirement	Match actual grade, recipe, completed treatment, geography/period and supply interface; disclose missing providers/substitution
disclosure	Actual configuration, make/buy, coverage/conditional absence, transport/treatment, measured denominator and uncertainty

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
causal	site	Separate configurations and subdivisions first; allocate common residual by measured causal load, operating time or appropriate physical driver, retain numerator and denominator records and uncertainty. Do not average unrelated appliance models or use appliance mass automatically for every utility.
rejects	accepted	Include actual rejects, rework and qualification burdens in attributable Q for accepted output; only accepted net mass/count enters denominator. Segregate recycling transfer and treatment; do not assume avoided-product credits or zero upstream recycled burden.

8. Foreground Data Collection, Calculation, and Quality Rules

Data Collection Protocols

protocol_id	process_id	flow_role	record_type	raw_fields	collection_method	unit	frequency	temporal_coverage	site_scope	aggregation_rule	quality_evidence
cp_mass	dispatch	reference product	weighing	model; configuration; serial number; accepted net mass M	Weigh the accepted complete machine on a calibrated scale, excluding transport packaging; reconcile the same configuration and acceptance record.	kg	each accepted lot	common manufacturing period	same configuration/site	accepted net mass per machine	calibration/tare/included accessories/acceptance
cp_material	all	actual inputs	meter_issue	specific species/grade; supplied state; issue; each moisture/density/assay; make/buy; stocks; Q; N	Reconcile each exchange metering/stores/recipe and paired returns in common period; Q includes rejects/rework and each term own assay.	kg	each batch or continuous meter	common manufacturing period	same configuration/site and supplier	attributable quantity / accepted machines	grade/composition tests/meters/stocks
cp_energy	all	electricity and heat	meter	process meters; gross imports; actual generation; exports; storage; each supply/return steam mass pressure temperature enthalpy; net invoice; Q; N	Reconcile process meters in same period/units; shared services only unassigned residual, investigate negative residual. Each steam supply/return uses own kg and MJ/kg/common zero, return deducted once.	MJ	continuous meters/each test	common manufacturing period	same configuration/site	attributable energy / accepted machines	calibrated meters/delivery interface/thermodynamics/allocation uncertainty
cp_waste	all	specific waste	transfer	each stream mass and own moisture/assay; beginning/end stocks; internal return; external treatment; Q; N	Weigh/sample treatment transfers, distinguish return/reuse/recycling/disposal without assumed substitution credit.	kg	each transfer lot	common manufacturing period	same configuration/site and treatment interface	attributable waste / accepted machines	waste tickets/sampling/stocks
cp_emission	all	specific species/compartment	species_measurement	actual species/compartment; concentration; exhaust or liquid flow; wet/dry temperature/pressure; capture/destruction; own assays; Q; N	Use matched species/compartment measured or verified actual technology factors; investigate closure, capture not destruction, residual not air emission.	kg	actual tests/emission periods	common manufacturing period	same configuration/site boundary	attributable emission / accepted machines	sampling/flow/combined uncertainty

Raw-period protocol: N is accepted count of the same configuration, D the sum of calibrated accepted net masses, M=D/N. Each Q is the attributable common-period exchange including reject, rework and factory-test burden; first q_item=Q/N then q_ref=Q/D. Packaging/reject mass stays out of D. Retain actual original units, own composition, stocks and reaction records.

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

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
species_emission_method	cp_emission	For each actual species use post-control concentration times matched exhaust or liquid flow over the same period; correct actual wet/dry basis, temperature/pressure, reference state and native units. Fugitive releases require an independently measured basis, not inferred from stack readings. Keep species/compartment and capture/destruction separate.	species sampling; matched flow/time; calibrated meters; fugitive evidence
complete_bom	actual configuration	Cover all actual exchanges; separate make/buy/accessories/fills/test charges; gaps explicit	actual BOM/routes/suppliers
period_normalization	all inventory rows	Qattr is each attributable exchange in the same configuration/common period including reject/rework/factory-test burdens; Naccepted is accepted count; Dnet is sum of calibrated accepted net masses; M=Dnet/Naccepted, q_item=Qattr/Naccepted, q_ref=Qattr/Dnet. Dnet excludes packing, reject and consumed test media; preserve each native numerator unit and exact conversion.	cp_mass; cp_material; cp_energy; cp_waste; cp_emission
mass_period	cohort	Same configuration/period/acceptance, calibrated mass/stocks; no cross-family mean	calibration/period ledger
balance_uncertainty	physical balances	Own water fraction/density/assay/reactions/paired returns; compare combined uncertainty	measurement/sampling/reaction/allocation evidence
provider_gaps	links	Each actual upstream/treatment matches state/geography/period; unverified not complete footprint	direct records/substitution disclosure

9. Validation Rules

rule_id	Applies to	Rule	source_ids
identity	dataset	Confirm principal function, domestic market, model/revision, delivered configuration and activated architecture. Every actual exchange needs matching identity/property/unit/provider; absent, zero and unknown remain distinct.	un-cpc-3-0-44822
denominator	all inventory rows	All inventory uses the same accepted cohort and common period. Verify calibrated accepted net mass and N; reject and packaging mass excluded. Check q_item=Q/N then normalization by same mean M; mixed configurations are invalid.
double_count	make_buy	Reconcile complete bought modules versus own materials and operations, retained fills/accessories versus factory consumption, paired internal transfers and external inputs. Count each actual burden once.
water_close	physical water records	For each term use its own measured water fraction, density and wet/dry basis: fresh and input moisture plus reaction water and beginning stocks minus final stocks, retained product, discharge and evaporation; internal returns cancel paired. Investigate measured closure against combined sampling/meter/allocation uncertainty; no universal tolerance.
species_close	material and chemical records	Close each contained metal/chemical separately using each input, product, scrap, sludge, liquid and release own matched assay and dry/wet basis, reaction stoichiometry and stocks. Gross mass is not contained element. No all-inventory mass rule applies to energy or transport.
solvent_close	solvent records	Distinguish retained solvent, recovered return, captured liquid/media, demonstrated destruction, wastewater/non-air residual and actual species air release. Capture is not destruction; an unexplained residual must be investigated, not assigned to air.
utility_close	energy records	Reconcile purchased imports, actual on-site generation, exports and storage changes with assigned fabrication/drive/electronics/integration/test/dispatch loads in the same period and units. Shared row ONLY unassigned residual; investigate negative residual against period, unit and combined measurement uncertainty without clipping.
steam_close	steam and condensate	Use supply kg times supply own MJ/kg and return kg times return own MJ/kg at measured pressure/temperature relative to common zero. If gross supply, subtract return once; if already-net invoice, do not subtract again. Keep physical steam/condensate mass balance independent from energy.
species_emissions	air releases	Validate every emitted species and compartment independently. Fuel carbon balance cannot alone establish CO or NOx. NO2 mass is not NOx reported as NO2 equivalent; keep reporting conventions and actual species identities distinct.

10. Published Dataset Profile

dataset_role	primary_dataset
downstream_use	secondary_dataset; background_dataset; process; lifecyclemodel
