# Ultra-violet or infra-red ray apparatus, used in medical, surgical, dental or veterinary sciences

## 1. Scope and Applicability

This PCR applies to complete apparatus whose declared intended medical, surgical, dental, or veterinary function is delivered by ultraviolet or infrared optical radiation. It covers non-laser ultraviolet or infrared treatment, diagnostic, monitoring, or procedure-support apparatus supplied as a complete market-ready product, including the installed source, controls, housing, optical parts, power connection, and supplied accessories needed for the declared function.

The product definition is determined by intended purpose and radiation function, not merely by the presence of a lamp or heater. General-purpose lighting, space heating, tanning, industrial curing, material testing, germicidal fixtures without the assigned medical, surgical, dental, or veterinary intended purpose, laser equipment, ionizing-radiation equipment, electro-diagnostic apparatus whose diagnostic function is not delivered by ultraviolet or infrared radiation, and separately marketed consumables or replacement lamps are outside this boundary. Product variants using ultraviolet, infrared, or both are represented by conditional atomic rows; they are not multiplied across every lifecycle stage.

The base foreground package covers component receipt, apparatus assembly, final test, and packaging through the factory gate. Distribution, use and maintenance, and end of life are conditional modules that become mandatory whenever the study claims those lifecycle stages or a cradle-to-grave result. Applicable legal or conformity obligations remain jurisdiction- and intended-use-specific; this PCR does not certify medical-device safety or regulatory compliance.

| starting_condition_role | Foreground entry point for apparatus manufacturing; upstream component and material production remains represented by linked secondary or background datasets |
| product_classification_scope | The semantic ultraviolet/infrared medical-apparatus boundary described in sections 1 and 2; CPC 48122 is classification context rather than canonical identity authority |
| recursive_input_rule | A same-category apparatus or subassembly purchased for integration is recorded once as an incoming product flow with its upstream dataset; it is not recursively decomposed again inside the receiving process |

| disclosure | Declare assembly and packaging sites, included lifecycle modules, cut-offs, shared-facility treatment, product configuration, software/control content, sterilization or cleaning steps, supplier data coverage, electricity geography, distribution routes, use profile, maintenance, and end-of-life scenario |

| `boundary_lifecycle_modules` | lifecycle claims | A cradle-to-grave or downstream claim must add distribution, installation if material, use electricity, cleaning or disinfection when prescribed, maintenance and source replacement, and end-of-life collection and treatment. A factory-gate dataset must state that these modules are excluded. | `eu-pef-2021-2279`; `eu-mdr-2017-745` |

## 7. Allocation and Co-product Handling

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| `allocation_subdivide_first` | multi-product and shared processes | Avoid allocation by subdividing assembly, test, packaging, and utility records to the declared apparatus family whenever separate measurements or production records are available. | `eu-pef-2021-2279` |
| `allocation_physical_driver` | residual shared burdens | When subdivision is not possible, allocate shared electricity, water, cleaning, and packaging operations using a documented causal physical driver such as machine time, test time, metered energy, processed mass, or accepted unit count. Economic allocation requires a documented reason that no causal physical relation is practicable. | `eu-pef-2021-2279` |
| `allocation_rejects` | rejected apparatus and components | Attribute burdens through the point of rejection using measured process participation; do not distribute post-rejection rework or treatment to accepted output unless the chosen physical driver causally requires it. | `eu-pef-2021-2279` |
| `allocation_recycling` | end-of-life recovery | State the recycled-content and end-of-life attribution convention, use it consistently for incoming and recovered materials, and prevent double credit between the apparatus system and downstream material systems. | `eu-pef-2021-2279`; `eu-weee-2012-19` |
