Musical audio discs, tapes or other physical media

1. Scope and Applicability

This PCR supports foreground data production for new physical carriers sold with recorded musical audio. Replicated audio CD is the representative route; CD-R recording, PVC vinyl pressing and bulk-reel cassette duplication are conditional routes. Each dataset fixes one carrier construction, programme and supply state. This methodology is needed to distinguish content reproduction, carrier manufacture, title-dependent tooling, yield loss and packaging burdens.

Other physical music carriers remain within category scope, but a dataset for a different construction must first document the actual route and add its concrete exchanges. A CD inventory is not a proxy for flash media, multilayer optical discs or historical shellac records. Blank carriers, video products, audiobooks, non-musical recordings, downloads, streaming and playback equipment are excluded reference products.

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	carrier format and construction; musical programme identifier and duration; recording technology and playback format; accepted unit count and measured net mass per unit; integral shell/label boundary; packaging bill of materials; recording quality acceptance; plant and reporting period; supplier starting conditions; recycled fraction; utility geography and voltage

Declare every qualifier in dataset metadata or equivalent product records. The 1 kg basis is a manufacturing declared unit, not evidence that equal masses deliver equal listening service. Album comparisons require aligned programme, fidelity, media count, use and end-of-life scenarios. Sources: weber-music-delivery-2010

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_mass	accepted media	Mass	kg	Net music-bearing carrier mass includes integral cassette shell and attached label; excludes jewel case, sleeve, booklet, wrap and shipping carton. Preserve count and measured per-item mass.
count_conversion	items and packaging	Mass	kg	Mass = count × measured mean unit mass; document sampling by format and lot. Convert music-program units separately using media count per album.
tape_conversion	bulk tape and splices	Mass	kg	Mass = used length × measured linear mass. Tape duration does not identify length without recording speed, tracks/sides and leader allowance.
energy_conversion	purchased electricity	Net calorific value	MJ	Preserve delivered electrical energy; 1 kWh = 3.6 MJ. Do not convert to primary energy within the exchange or add grid emissions as direct site emissions.
gas_conditions	gaseous natural gas	Volume	m3	Declare reference temperature, pressure and dry/wet basis; convert meter readings consistently. An energy invoice needs a supplier-specific calorific value to infer volume.
water_density	supplied water and blowdown	Mass	kg	Convert measured volume with documented density and temperature; distinguish withdrawal, recirculation, evaporation and discharge.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Supplier-delivered formulated resin, finished stamper, coated tape or blank optical carrier and purchased components, with documented upstream burdens
starting_condition_role	Foreground collection interface; does not remove upstream manufacture from the lifecycle boundary
product_classification_scope	Recorded musical physical media; CPC context does not substitute for carrier state
recursive_input_rule	One supplier interface per purchased same-category input; internal transfers tracked once
upstream_dataset_requirement	Cover actual formulation, component manufacture, supplier energy, inbound transport and waste treatment; disclose geography, technology and unresolved coverage
disclosure	Declare starting state, exclusions, integrated versus purchased operations and separate gate-to-gate from upstream-linked results

rule_id	applies_to	Rule	source_ids
boundary_scope	manufacturing_system	Compile a cradle-to-factory-gate manufacturing dataset including acquired materials and components, their upstream production and inbound transport, mastering, carrier production or recording, attributable utilities, packaging and treatment of production waste. Publish gate-to-gate observations separately from linked upstream results.	ghg-protocol-product-standard-2011
boundary_route	carrier_construction	Declare one carrier construction and route per dataset. Replicated CDs need moulding, metallization and protection; CD-R recording starts with supplied blank discs; PVC vinyl needs pressing; bulk tape duplication needs recording and loading. A format name alone cannot justify using another route inventory.	nist-optical-disc-care-2003; cci-recording-media-care; nac-cassette-production-2026
boundary_supplied_components	supply_boundary	For purchased finished stampers, coated/slit tape, assembled shells, printed labels and packaging, obtain upstream datasets covering all embedded constituents and conversion. If these are made on site, replace the purchased-component boundary with measured production and its atomic exchanges; do not count both. Include attributable master preparation even for short runs.	nist-optical-disc-care-2003; nac-cassette-mastering-2026; gz-media-music-manufacturing
boundary_completeness	site_instantiation	The cards are a core collection structure. Before a site dataset is complete, add each actual omitted exchange, including a specific process chemical, spent lacquer, spent stamper, exported resin scrap, printing colour, fuel, purchased steam, refrigerant loss or measured combustion species. Record individual composition, amount and destination; absence needs evidence and a missing UUID is never a cut-off.
boundary_recursion	same_category_inputs	When already recorded musical media are purchased for repacking or further processing, record their delivered state and a supplier dataset once. Stop physical tracing at that documented supplier interface, not at the classification label. Internal transfers are reconciled without duplicate external inputs or final outputs.
boundary_downstream	excluded_stages	Distribution after the factory gate, retail, playback devices and listening energy, consumer travel, and consumer end-of-life are separate downstream scenarios. Creative performance, copyright and royalties are outside this physical manufacturing dataset; disclose that exclusion. Do not claim a complete listening-service comparison or full product-GHG conformance from this partial lifecycle.	weber-music-delivery-2010; ghg-protocol-product-standard-2011

6. Process Inventory Structure

Process Map

process_id	process_name	inclusion	inclusion_condition	role	quantitative_reference
mastering	Master preparation and tooling	conditional	Purchased stampers for replicated CDs or pressed vinyl	foreground manufacturing	1 kg accepted recorded media
optical	Optical replication or CD-R recording	conditional	Declared optical audio medium	foreground manufacturing	1 kg accepted recorded media
vinyl_pressing	Vinyl pressing	conditional	Declared PVC grooved audio disc	foreground manufacturing	1 kg accepted recorded media
tape_duplication	Tape duplication and loading	conditional	Declared bulk-reel cassette route	foreground manufacturing	1 kg accepted recorded media
site_energy	Site energy and water	required	All production routes; individual fuel and water conditions apply	foreground manufacturing	1 kg accepted recorded media
finishing	Finishing, packaging and release	required	All accepted media; each packaging component is conditional	foreground manufacturing	1 kg accepted recorded media

Processes are foreground collection partitions of one integrated manufacturing system. Internal work-in-progress quantities are reconciled in batch logs; only the released carrier is the reference output. Apply each card condition without duplicating the common utility or finishing ledger.

7. Allocation and Co-product Handling

rule_id	applies_to	Rule	source_ids
allocation_subdivide	shared_processes	First separate product campaigns and directly meter attributable processes. If unavoidable, allocate by a demonstrated physical relationship; use economic allocation only with a documented reason that physical allocation is unsuitable and a sensitivity analysis.	ghg-protocol-product-standard-2011
allocation_tooling	mastering_and_stampers	Allocate master and stamper preparation by documented lifetime accepted copies of that title/format, including test and failed runs in the burden numerator. Record replacements and partial tool lives; do not assume infinite reuse.
allocation_utilities	site_energy	Use route submetering where possible. Otherwise allocate campaign electricity by measured power-time demand, process heat by measured heat demand and packaging by actual unit counts; reconcile shares to the site meter. Music duration alone is not a causal allocation basis for moulding.
allocation_recycling	scrap_and_recycled_content	Track internal regrind as an internal loop, counting reprocessing energy and loss once. Apply a disclosed recycled-content approach to external recyclate and waste treatment; do not subtract hypothetical virgin-material displacement from the factory-gate result. Sold usable off-spec media require separate product accounting, not automatic waste status.	ghg-protocol-product-standard-2011

Calculation Rules

rule_id	Applies to	Formula or rule	Inputs	Output	source_ids
normalize	all inventory	q_i = Q_i,allocated / M_good; M_good = N_good × measured mean carrier mass. Keep all input, output and stock quantities on the same time boundary.	quantity; allocation_share; accepted_count; unit_mass	normalized_exchange
tool_share	mastering	Allocate total attributable tool and master burden by batch good-copy count / lifetime good-copy count; then normalize. Reconcile partial lifetimes at update.	tool_mass; good_copy_history	allocated_tool_mass
site_share	site_energy	Allocated quantity = site quantity × measured causal share; all shares must reconcile to the metered total.	meter_quantity; causal_driver	allocated_utility
supply_link	upstream_dataset	Link each net purchased physical input once to compatible production and inbound-transport data; report coverage and avoid duplicating embedded components.	supplier; product_state; quantity; transport	upstream_link	ghg-protocol-product-standard-2011

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
identity	all rows	Retain exact formulation, supplied state, batch, supplier and destination; resolve missing flows before downstream claims of full matching	Bills of materials and supplier specifications
coverage	reporting period	Cover full campaigns including setup, test runs, rejects, shutdowns and stock changes; disclose gaps and seasonal or product-mix bias	Batch/meter reconciliation
quality	accepted output	Record sample method, approved audio/content criteria, playback equipment and physical checks; do not use theoretical output as accepted output	Release and rejection logs
uncertainty	all quantities	Retain measurement uncertainty and actual variability; no literature-derived default amount or numeric range is supplied by this PCR	Calibration and source applicability assessment

9. Validation Rules

rule_id	applies_to	Rule	source_ids
validate_identity	reference_product	Require recorded musical content, a declared physical carrier and all reference qualifiers. Blank media, video, spoken-word-only products and playback hardware cannot be the reference output.	un-cpc-3-0-structure-2025
validate_rows	inventory	Every instantiated exchange must be atomic, have a quantity and unit, and link to a collection record or calculation. Each UUID must match flow type, state and measurement; a missing UUID must remain explicit.
validate_balance	campaign	Reconcile external material inputs plus opening stocks with accepted media, separate packaging, waste, emissions and closing stocks. Investigate discrepancies against instrument uncertainty and documented transformations rather than inventing a generic tolerance.
validate_route	process_coverage	Require every applicable process and site-specific extension, matched supplier boundaries and one utility ledger. CD-R supply must not duplicate replicated-CD constituent inputs; coated tape must not duplicate upstream coating manufacture.
validate_quality	release_and_data	Use campaign acceptance records for readable, correctly sequenced content and carrier-specific physical inspection. Retain failed copies in consumption and reject records. Assess technological, geographic and temporal representativeness, completeness and measurement reliability.	nist-optical-disc-care-2003; cci-recording-media-care; ghg-protocol-product-standard-2011
validate_ranges	quantitative_evidence	Use measured foreground values. External inferred intervals require at least two independent original sources with compatible carrier state, unit and boundary and an explained synthesis. One publication’s scenarios are not independent; exact normalization and unit conversion are not ranges.

10. Published Dataset Profile

Field	Value
dataset_role	secondary_dataset; background_dataset
downstream_use	Manufacturing input to a declared physical-music product lifecycle or distribution model
allowed_use	Same carrier construction, product state, technology and supply boundary; scaled by measured mass/count conversion
excluded_use	Unqualified substitution across formats; complete streaming-versus-physical comparisons; retail/playback/end-of-life claims without added scenarios
required_metadata	carrier format and construction; musical programme identifier and duration; recording technology and playback format; accepted unit count and measured net mass per unit; integral shell/label boundary; packaging bill of materials; recording quality acceptance; plant and reporting period; supplier starting conditions; recycled fraction; utility geography and voltage
required_quality_disclosure	Collection dates, instruments, sample coverage, allocation, supplier links, waste routes, UUID gaps, uncertainty and partial lifecycle boundary
update_trigger	Carrier or formulation change; new supplier/grid; route or packaging change; revised yield, tooling life or evidence; significant coverage correction
