Electric blankets

1. Scope and Applicability

This candidate governs foreground production of complete domestic electric textile overblankets and underblankets at the factory gate. Its reference is manufactured product mass, not an hour of warmth. Manufacture includes actual textile preparation, heater integration, controls, electrical connection, acceptance and dispatch. Consumer operation, laundering and end-of-life are separate downstream scenarios. Beurer supplies both underblankets and overblankets; its documented nonwoven blend and removable controls are examples, not a universal BOM. Independent patented constructions show insulated cable and integrated conductive yarn alternatives. [beurer-ub60; beurer-throws; woven-heater-patent; cable-heater-patent]

Passive blankets, standalone heater parts, heated clothing, seat heaters and medical thermal therapy devices require their own principal-function and classification review. A patent using “blanket” broadly for pads does not prove those products belong to this domestic boundary. Actual novelty, battery supply or an unusual heater design remains eligible for product review; it requires its own verified BOM, specific rows and supplier evidence rather than an unsupported method exclusion.

Declare every required qualifier in the foreground package. The generic reference flow supports manufactured electric-blanket identity and Mass; it supplies no geography, BOM, provider or empirical quantity. Missing qualifiers make the concrete 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.
physical_basis	physical material and species records	Mass	kg	Measure each actual material and each contained species on its own matched assay and wet/dry basis. Gross cable or fabric mass is not metal, polymer or solvent content. Convert length/count using actual batch mass or grade-specific measured linear/areal mass.
utility_basis	utility records	Energy	kWh	Keep delivered electricity units, voltage, supplier/site geography and time period; document kWh/MJ conversions. No source-specific waste-incineration electricity is a generic factory grid supply.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Actual purchased fabric/yarn, heater cable/yarn, control and connection subassemblies or documented raw-grade fabrication inputs
starting_condition_role	foreground_boundary_choice
product_classification_scope	Domestic electric textile blanket manufactured product
recursive_input_rule	A purchased unfinished/complete blanket entering further finishing is one upstream intermediate with documented included operations; do not recurse or duplicate its embedded inputs
upstream_dataset_requirement	Each purchased exchange needs actual grade, geography, technology and delivered interface matching supplier evidence
disclosure	Site, period, actual make/buy matrix, included accessories, upstream links, omitted operations and downstream scenario separation

rule_id	applies_to	rule	source_ids
b_makebuy	all processes	For each textile layer, heater, controller and connection, choose complete purchased component or on-site fabrication. The former includes its embedded materials upstream once; the latter records every actual individual grade, chemical, utility, waste and release. Add distinct atomic rows for actual alternatives not listed here; examples are not compulsory recipes.
b_factory	all processes	Include transport into the declared factory boundary, actual conversion, joining, testing, rework, reject treatment and packaging; transport providers require separate mode-specific freight rows. Later space/body heating, laundering, product lifetime and disposal belong only to explicitly separate lifecycle scenarios.

Rows below are conditional atomic interfaces. Record actual material grade and supplier, and distinguish not_applicable (verified absence), measured zero and unknown. Complete purchased assemblies replace, rather than accompany, embedded raw-material inputs. Extend the package for each actual resin, dye, adhesive formulation, flux, solder alloy, textile, fuel or species individually; unknown composition blocks affected completeness.

7. Allocation and Co-product Handling

rule_id	applies_to	rule	source_ids
a_cohort	all processes	Keep each model/configuration and its actual accepted output separate. Allocate shared factory operations by measured causal activity (machine time, actual load or area-time), disclose the basis and reconcile to the original period totals. Do not average different heater/control/textile configurations.
a_scrap	physical material records	Internal offcut or rework returns cancel as paired transfers, not free external inputs or coproduct credits. Include scrap conditioning and all rejected/reworked burden. External recycling or treatment uses documented receiver and allocation convention; do not assume avoided virgin material.

8. Foreground Data Collection, Calculation, and Quality Rules

Use one traceable site period and one configuration cohort. Q is the attributable period exchange, including its share of reject/rework and actual shared services; N is accepted complete units; D is the sum of individually calibrated accepted net masses for that same configuration; M = D/N. Form q_item = Q/N, then q_ref = q_item/M = Q/D. Packaging, rejected units and scrap never enter D. These are collection operations, not empirical default factors. Every protocol retains raw period totals before conversion.

Count complete purchased component upstream once.	kg	each batch and period close	same production period	actual factory operation and supplier interface	attributable exchange / accepted units	weighbridge/scale; supplier composition; stock reconciliation; receiver evidence
cp_utility	all processes	electricity	meter records	site; period; units; voltage; imports; generation; exports; storage; returns; all submeters; configuration; causal allocation; Q; N	Read calibrated same-period meters and invoices. Assign actual textile/heater/assembly/test/dispatch loads first; shared service is only the unassigned site residual. Reconcile imports, actual generation, exports and storage changes without double counting. Investigate negative residuals with period/unit/combined meter uncertainty; never clip to zero. On-site generation needs its own fuel and species-specific release rows.	kWh	each test batch and period	same production period	factory utility boundary	attributable exchange / accepted units	meter calibration; bills; allocation and site reconciliation
cp_chemistry	assembly	individual adhesive/solvent/species	chemical and sampling records	chemical grade; formulation; purity; wet/dry basis; actual inputs; stock changes; retained product; recovered solvent; capture media; measured destruction; waste liquid; actual air release; Q; N	Measure species mass for each term using its own matched assay; balance inputs plus reaction production against product retention, stocks, recovered material, captures, liquid/solid waste, actual destruction/reaction consumption and measured releases. Capture is not destruction; unexplained residual is not automatically air. Resolve closure against actual combined sampling, meter and allocation uncertainty.	kg	each batch and sampled campaign	same production period	actual chemical use boundary	attributable exchange / accepted units	SDS/formulation; assays; capture/treatment records; sampling method and uncertainty
cp_water	test	water and wet-test discharge	meter and moisture records	purchased water; feed moisture; opening/closing water stocks; actual product moisture; evaporation; discharge; reaction production/consumption; paired internal returns; discharge assays; Q; N	Measure all actual water-bearing inputs, outputs and stock changes on matched period/basis. Each feed, product, scrap, sludge, wastewater and opening/closing stock term uses its own measured water fraction/moisture; each liquid volume conversion uses its own measured density. Gross wet-waste mass is not water mass; never apply one moisture percentage to all terms. Include reaction water and pair internal returns; independently measure discharge/evaporation where available and investigate residual against combined uncertainty. Pollutant mass uses each discharge species concentration and actual water quantity; do not infer pollutant amount from water alone.	kg	each wet-test batch and period	same production period	factory wet operation	attributable exchange / accepted units	meters; moisture samples; laboratory assay; treatment contract

Actual raw-period water closure is fresh-water input + feed moisture + opening water stock + reaction water generation = product moisture + scrap/sludge water + external discharge water + evaporation + closing water stock + reaction water consumption. Separate each actual aqueous waste stream and use its own assay/density; paired internal water returns cancel. Investigate closure with combined measurement, sampling and allocation uncertainty before normalization; no universal closure tolerance.

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
water_balance	test_water; test_wastewater; evaporated_water	Fresh water + feed moisture + opening water stock + reaction water generation = product moisture + scrap water + sludge water + external discharge water + evaporation + closing water stock + reaction water consumption. Each actual feed/product/scrap/sludge/wastewater/stock term uses its own measured water fraction and wet/dry basis; each liquid volume uses its own measured density. Gross wet waste is not water mass. Paired internal returns cancel. Reconcile the actual raw period before normalization and investigate closure with combined measurement, sampling and allocation uncertainty; no universal tolerance.	cp_water; actual water fractions; actual liquid densities; matched raw-period water and reaction/stock records	Closed actual raw-period water account

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
dq_trace	all processes	Retain actual model-specific BOM, make/buy matrix, test acceptance, raw totals, uncertainty, supplier interfaces and missing/zero/absent distinctions. Source patents are architecture examples; public product pages establish no factory operating factors.	Signed factory and supplier records
dq_balance	physical material and species records	Material/species inputs plus reaction production equal outputs plus stock increase and reaction consumption after paired internal transfers cancel. Each product/scrap/sludge/wastewater/release term uses its own actual assay and wet/dry basis; never apply one alloy fraction to all terms. Investigate imbalance against measured combined uncertainty with no universal tolerance. Fuel carbon alone does not determine CO or NOx.	Assays; stock/reaction records; closure and uncertainty report

9. Validation Rules

rule_id	applies_to	rule	source_ids
v_reference	reference product	Require actual domestic principal function, model/configuration qualifiers, accepted complete delivered inclusion list and calibrated net masses. N and D must cover the same accepted cohort; M = D/N; reconcile Q/N then q_item/M to Q/D. Do not mix configurations or include packaging/reject mass in D.
v_routes	all processes	Every actual heater conductor, insulation layer, textile, controller/sensor, cord/connector, adhesive and auxiliary has one evidenced make/buy interface. Complete purchased modules and their embedded inputs cannot coexist. Conditional alternatives require BOM evidence; not_applicable needs verified absence. All actual exchanges have atomic physical/chemical identities, matched unit support and provider interfaces; unresolved fields remain gaps.
v_balances	physical material and species records	Close each material/species and water account with matched own assays, moisture, stocks, reactions, product, scrap, waste liquid/solid, measured releases and paired internal returns. Distinguish recovery, capture and actual destruction. Investigate residual and uncertainty; missing composition or fate makes affected validation inconclusive.
v_energy	utility records	Same-period site reconciliation binds imports, generation, exports/storage and all assigned process loads. Shared services include only unassigned residual, with causal allocation. Negative residuals need investigation; consumer power/time, product-webpage mass and an incineration-specific electricity UUID are not factory defaults.
