Industrial single-jersey circular knitting machinery manufacture

1. Scope and Applicability

This PCR covers manufacture of complete large-diameter single-jersey circular weft-knitting machines with declared diameter, gauge, needle/sinker mechanism, yarn feeding, drive, take-down and controls. Distinguish conventional and relative/spring-sinker layouts and actual delivered accessories. Include the complete configured machine at acceptance, with installed knitting tools, guard/frame, drive/control, feed/take-down modules and declared delivered creel. Exclude warp knitting, flat knitting, double-jersey/dial machines, seamless individual-item/hosiery machines, stitch-bonding, gimp/lace/embroidery/braid/net/tufting machines, looms and separately sold parts. CPC 44613 is broader than this boundary. Textile manufacturing in the customer mill, routine yarn consumption, fabric yield, mill utilities, maintenance/replacement needles and end-of-life are outside this manufacturing inventory. Actual factory knitting trials, test yarn, trial fabric handling and attributable utilities/lubricant/waste belong to manufacture. No textile production service or operating lifetime is included.

2. Product Category Identity

Field	Value
Reference amount	1
Reference product flow	Knitting machines, stitch-bonding machines, machines for making gimped yarn, tulle, lace, embroidery, trimmings, braid or net and machines for tufting 533238d4-94ee-4db4-8e64-cfe66821248f
Reference flow property	Mass 93a60a56-a3c8-11da-a746-0800200b9a66
Reference unit group	Units of mass 93a60a57-a4c8-11da-a746-0800200c9a66
Reference unit	kg
Required qualifiers	model/serial or batch; diameter/gauge; needle tracks and sinker layout; installed needle/sinker counts and grade/state; cylinder/cam/feeder/drive/take-down/control; delivered creel/guard/accessory and electronics inclusion; clean unloaded state without yarn/fabric; retained lubricant; measured M; factory/site and period; input gates; test yarn, trial duration and inspection; actual covered stages

Weigh the same complete accepted delivery configuration on calibrated scales. Packing/shipping gross weight, nominal catalogue weight or a machine loaded with yarn/cloth does not replace M. Needle and sinker counts identify configuration; actual installed batch mass contributes to M without an assumed unit-piece weight. Kilogram normalization does not establish equivalent fabric-making performance across gauges, layouts or products.

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 machine 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.

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 finishing, replace site chemistry and energy with the exact purchased service or finished-part record and disclose its coverage.

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.

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

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	wet_surface; powder_finish	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, test-yarn-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 needle/sinker counts and their measured batch mass. 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

10. Published Dataset Profile

Field	Value
dataset_role	Manufacturing foreground process for a configured accepted machine
downstream_use	secondary_dataset; background_dataset
allowed_use	Input to a declared machinery supply model with identical configuration and disclosed upstream coverage
excluded_use	Textile production service, mill operation, or life-cycle comparisons across gauges, sinker layouts and fabric products without separate functional modelling
required_metadata	Model, configuration, empty state, M, retained fluids, manufacturer/site, reporting period, process route, voltage/geography, supplier gates, transport/packaging scope and allocation
required_quality_disclosure	Measured versus estimated quantities; unresolved identities; unmeasured emissions and components; upstream linkage completeness; uncertainty, data age and configuration limitations
update_trigger	Changed needle/sinker layout, diameter/gauge, BOM, coating/lubricant chemistry, test-yarn composition, supplied component, energy mix, acceptance specification or mass protocol
