General business productivity and home use applications, packaged

1. Scope and Applicability

This PCR applies to published, standardized application software supplied as a physical packaged product for general business productivity or home entertainment, reference, or education. Covered examples include office suites and their word-processing, spreadsheet, and simple-database functions; graphics and project-management applications; computer-based training; and home reference or education applications.

The PCR excludes operating systems, network software, database-management platforms, development tools and programming languages, computer games, and other application-software subclasses. It also excludes custom software development, software-as-a-service, cloud-hosted application services, and application-software downloads. CPC 3.0 places downloadable application files that are stored locally for later execution or installation in the separate subclass 84342. A data producer shall not use this PCR merely because software is commercially licensed; the declared product must be the physical packaged-product supply covered here.

The default foreground boundary is release development, build, testing, mastering, physical-media assembly, and retail packaging through the packaged product at the producer gate. Distribution, customer-device operation, maintenance after release, and end-of-life treatment are outside the default boundary and require separately declared modules if included in a study.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_product_mass	Finished packaged application software and mass-based material or waste rows	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Weigh or calculate net mass at the stated moisture and packaging condition.

release_allocation_denominator	Release-level development, build, test, and mastering records	Mass	kg packaged product	Normalize release-level records by the verified mass of conforming physical packaged units produced for the same release and reporting period. Exclude download-only units and SaaS subscriptions from the denominator.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Project or release initiation with software requirements, pre-existing source components, third-party dependencies, and the intended physical packaged-product configuration identified
starting_condition_role	Starting inventory condition for release development and for tracing purchased components that enter the physical packaged product
product_classification_scope	Published general business productivity and home-use application software supplied as a physical packaged product; download-only application files belong to a separate CPC subclass and are outside this PCR
recursive_input_rule	A purchased component already classified as the same packaged application category shall be recorded once as an upstream product input with a conforming upstream dataset; do not recursively reconstruct its development and packaging inside the receiving process
upstream_dataset_requirement	Electricity, recorded optical disc, paper box, paper insert, and any added medium or packaging component require geography-, technology-, and product-state-appropriate upstream datasets
disclosure	Declare included software components, release/build/test infrastructure, physical medium, packaging configuration, producer-gate geography, reporting period, allocation denominator, exclusions, and the asset-by-asset supporting-hardware assessment with inclusion or cut-off decisions

rule_id	Applies to	Rule	source_ids

Screen each actual developer workstation, build/test server, storage device, and network device supporting the release using a documented asset-specific materiality assessment. Add every material asset as its own concrete product exchange linked to an appropriate hardware dataset and allocate it by disclosed time and resource shares. Exclude an asset only under a disclosed quantitative cut-off calculation retained with the dataset; absence of a claim or missing data is not a zero. Preserve the device type, model or configuration, asset identifier, geography, lifetime basis, and allocation variables, and never aggregate different devices into an umbrella hardware row.	gsf-sci-1-1
boundary_background_emissions	Purchased electricity and materials	Use upstream datasets for emissions embodied in purchased electricity and materials; do not duplicate those emissions as direct elementary outputs unless the foreground process directly releases them.
boundary_optional_modules	Distribution, operation, maintenance, and end of life	Keep these outside the default producer-gate dataset. When a study adds one, report it as a separate module with its own functional basis, scenario, inventory, and exclusions.	gsf-sci-1-1

9. Validation Rules

rule_id	Applies to	Rule	source_ids
validate_identity_and_route	Product eligibility	Fail if the declared product is download-only, hosted/SaaS, custom-developed, a computer game, system software, or another excluded software subclass; verify the physical packaged-product configuration and covered function.	un-cpc-3-0-47821; un-cpc-3-0-84342
validate_reference_flow	Reference flow	Require exactly 1 kg after normalization, the confirmed product-flow UUID, Mass property, kg unit, and every required qualifier.
validate_inventory_completeness	Process inventory	Require both process sections and all nine prescribed row ids; require a value, measured zero, or explicit not-applicable state for each route-applicable row. Every material device from the hardware assessment shall appear as its own additional exchange.
validate_atomic_flows	Inventory identity	Reject umbrella utility, packaging, hardware, waste, or emissions labels. Each row shall represent one exchange; recorded_optical_disc_input and waste_recorded_optical_disc_output remain UUID-empty until exact state-code 100 identities are confirmed.
validate_electricity_conversion	Electricity rows	Recalculate kWh-to-MJ conversion and release/output normalization; require one grid geography and delivery boundary for each electricity dataset used.	gsf-sci-1-1
validate_mass_balance	Physical-media assembly and packaging	Check separately for discs, boxes, and inserts that issued mass minus genuine unused returns equals retained conforming-product component mass plus measured outgoing material waste and documented stock or measurement adjustments within disclosed uncertainty. Consumed rejects must remain in inputs; unexplained residuals are findings.
validate_hardware_boundary	Supporting infrastructure	Require the asset-by-asset materiality screen. Fail when a material asset is omitted, unlike devices are combined in one row, an exclusion lacks its quantitative cut-off calculation, or missing data are treated as zero.	gsf-sci-1-1
