Cinematographic projectors

1. Scope and Applicability

This PCR governs foreground production data for complete cinematographic projectors that transport and project motion-picture film. It covers factory assembly, alignment, functional projection testing, and sales packaging. It excludes digital or data projectors, slide or still-image projectors, screens, stand-alone parts, projection services, use, maintenance, and end-of-life.

The foreground boundary is gate-to-gate from receipt of purchased components and energy to a tested, packaged projector at the factory gate. A cradle-to-gate study must link each purchased input to an appropriate upstream dataset.

When constructing a foreground data package, the items listed in Required qualifiers must be declared in dataset metadata, process notes, reference flow comment, product description, or an equivalent data package field. Missing required qualifiers make the reference flow definition 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	Measure net finished-projector mass after final testing and before sales packaging; normalize all exchanges to 1 kg of output.
component_mass	Purchased components	Mass 93a60a56-a3c8-11da-a746-0800200b9a66	kg	Convert counts to mass from lot-specific weighing or documented supplier mass; do not use an unsupported nominal conversion.
electricity_energy	Assembly and test electricity	Net calorific value 93a60a56-a3c8-11da-a746-0800200b9a66	MJ	Preserve metered energy and convert kWh to MJ using 1 kWh = 3.6 MJ before normalization; declare meter scope and allocation.

5. System Boundary

The foreground boundary includes:

1. Include controlled component staging, assembly, optical and mechanical alignment, applicable lamp and sound-system installation, functional projection testing, inspection, attributable rework, and sales packaging.
2. Record each purchased component and energy carrier as a separate product input linked to an upstream dataset; do not absorb upstream production into assembly electricity or an undifferentiated material input.
3. Exclude purchased-component production, external transport, capital equipment, buildings, commuting, cinema operation, use-stage electricity, maintenance, and end-of-life unless separately modelled and disclosed.
4. Apply the Library of Congress motion-picture-film care guidance by keeping playback equipment clean and well maintained and, when archival film is used for testing, selecting a suitable low-heat projector bulb; the guidance supplies no inventory quantities.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
subdivide_before_allocation	Shared assembly, test, and packaging operations	Subdivide metered operations and records by product family before allocation whenever technically feasible.
physical_allocation	Residual shared inputs and wastes	If subdivision is infeasible, allocate by a documented causal physical driver such as machine time, test time, component throughput, or net output mass; do not use revenue when a physical relationship exists.
scrap_credit_disclosure	Recyclable production scrap	Report gross scrap and treatment route separately; any avoided-burden or substitution credit belongs outside the foreground inventory and must be disclosed as a scenario.

dq_range_gap	Important rows	Absence of external QA ranges is an evidence gap, not permission to invent defaults; prioritize foreground records and report uncertainty.	Manifest range-evidence register

9. Validation Rules

A foreground data package conforms only when:

1. the output resolves to 48b51d36-b781-4d3a-9c2d-305985200940, uses Mass and kg, equals 1 kg after normalization, and excludes sales packaging;
2. scope evidence demonstrates a motion-picture film projector rather than a digital, data, slide, or still-image projector;
3. each row is atomic, UUID-bearing flows retain audited properties and units, and xenon_arc_lamp remains UUID-empty until an exact public state-100 identity is verified;
4. component, electricity, reject, rework, and output records reconcile to one period and factory boundary;
5. a zero xenon-lamp amount has evidence of an alternative architecture, whose specific light source is recorded separately;
6. shared operations are subdivided or carry a declared allocation driver and worksheet;
7. required qualifiers, upstream links or gaps, outsourced operations, and boundary extensions are disclosed;
8. acceptance evidence covers applicable film-path, optical, lamphouse, take-up, focus, scratch, and sound checks.
