# Waterproof footwear with rubber or plastic outer soles and uppers, without a protective metal toe-cap

## 1. Scope and Applicability

This PCR applies to factory-gate production of waterproof footwear whose outer sole and upper are rubber or plastics and that does not incorporate a protective metal toe-cap. It covers integral moulded footwear and separately formed waterproof uppers and soles, including declared linings, sealing systems, finishes, and sales packaging. It excludes protective-metal-toe footwear, non-waterproof footwear, products outside the declared upper/sole materials, and downstream distribution, use, repair, and end-of-life.

## 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 mass after final conditioning and acceptance but before packaging; normalize all exchanges to exactly 1 kg reference output. |
| `count_to_mass` | pair or unit records | Mass and count | kg and pair or unit | Convert counts with product- and size-specific measured mass; retain sampling, scale calibration, size weighting, and calculation evidence. |
| `material_mass` | materials, chemicals, components, packaging, products, and solid wastes | Mass | kg | Use calibrated batch, warehouse, scale, or specification records; keep individual materials and waste streams separate. |
| `utility_measurement` | electricity, steam, natural gas, compressed air, and water | Energy, mass, or volume | kWh, MJ, kg, or m3 | Prefer sub-metering; otherwise allocate a complete reporting-period total using Section 7. |
| `conditioning_basis` | product, lining, and compound mass | Mass | kg | Declare conditioning and moisture basis; do not mix wet, conditioned, and dry masses without a documented conversion. |

## 5. System Boundary

### Boundary Abstraction

| Field | Value |
| --- | --- |
| declared_starting_condition | Declare whether each material enters as an individual compound ingredient, ready-to-form compound, granulate, formed upper or sole, integral shell, lining, or another named component. |
| starting_condition_role | Fixes the first foreground transformation and prevents double counting of supplier operations. |
| product_classification_scope | Finished waterproof footwear in the reviewed semantic scope corresponding exactly to CPC 3.0 code 29310. |
| recursive_input_rule | If finished footwear in the same category enters, record one supplier product input and its supplier dataset; do not recursively unpack it into the same foreground processes. |
| upstream_dataset_requirement | Use traceable upstream datasets for purchased materials, components, utilities, packaging, transport, and waste treatment. Finished leather lining requires supplier data covering tanning; do not add tanning to the footwear foreground unless the site performs it. |
| disclosure | Declare starting condition, routes, supplier-embedded operations, waterproof test, rework, waste destinations, allocation, upstream datasets, exclusions, and data gaps. |

| rule_id | Applies to | Rule | source_ids |
| --- | --- | --- | --- |
| `boundary_rule_1` | foreground manufacturing | Include every applicable on-site operation from declared inputs through compounding, forming, assembly, sealing, finishing, waterproof testing, inspection, and packaging, with direct utilities, wastes, and emissions. | ec-pef-method-2021; af-pefcr-3-1-2025 |
| `boundary_rule_2` | product scope | Require rubber or plastic outer soles and uppers, declared waterproof performance, and no protective metal toe-cap. | un-cpc-3-0 |
| `boundary_rule_3` | upstream materials | Model supplier production with traceable upstream datasets instead of duplicating supplier operations in the footwear factory foreground. | ec-pef-method-2021; af-pefcr-3-1-2025 |
| `boundary_rule_4` | conditional leather input | A finished-leather lining dataset shall cover relevant tanning chemistry, energy, water, waste, and emissions; tanning is not a mandatory footwear foreground process. | jrc-tanning-bref |
| `boundary_rule_5` | completeness | Record all applicable raw materials, energy, products, wastes, and direct releases to air and water; unresolved UUIDs do not justify omission. | ec-pef-method-2021 |
| `boundary_rule_6` | downstream stages | Exclude distribution, retail, use, repair, and end-of-life unless a downstream lifecyclemodel adds them without double counting. | ec-pef-method-2021; af-pefcr-3-1-2025 |
