# Carpets and other textile floor coverings, woven, not tufted or flocked

## 1. Scope and Applicability

This PCR applies to factory-gate foreground data packages for carpets and other textile floor coverings whose pile or surface structure is produced by weaving and is neither tufted nor flocked. It covers woven broadloom, rolls, rugs, and tiles when they retain this product identity, including products sold with integral backing or finishing layers.

Knotted carpets, tufted carpets, flocked floor coverings, felt floor coverings, resilient non-textile flooring, installation, use, maintenance, and end-of-life are excluded. Fibre, yarn, dyestuff, backing-compound, packaging, electricity, water, and waste-treatment production outside the reporting plant are represented by upstream datasets rather than recreated inside the foreground inventory.

The declared product is the saleable woven textile floor covering at the manufacturing plant gate. Wet processing, backing, coating, laminating, and other finishing steps are included only when performed for the declared product and must be disclosed as route qualifiers.

## 3. Reference Flow

| Field | Value |
| --- | --- |
| What | Woven carpet or other woven textile floor covering providing a finished floor-covering product |
| How much | 1 kg of net saleable product at the manufacturing plant gate |
| How well | Conforms to the declared construction, fibre composition, dimensions, mass per area, backing or coating state, and quality grade |
| How long or cycle | One completed manufacturing batch; service life is outside this factory-gate reference |
| reference_flow_link | The functional unit is realized by exactly 1 kg of the declared reference product output |

| Field | Value |
| --- | --- |
| Reference amount | 1 kg |
| Reference product flow | Carpets and other textile floor coverings, woven, not tufted or flocked `d54c5255-fc7f-4613-86da-08cf2afe8632` |
| 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 | fibre composition by mass; woven construction; product form; dimensions; mass per area; backing or coating state and composition; dyeing or printing state; quality grade; manufacturing geography; reporting period |

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 for that data package.

## 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 | Record net saleable product mass after trimming and before shipment; exclude pallets and transport packaging from reference mass. |
| `area_to_mass` | production or sales records expressed by area | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | Convert area to mass only with measured product-specific mass per area for the declared construction and batch; retain both the area record and measured conversion factor. |
| `moisture_basis` | yarn, textile intermediates, and finished product | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | State the moisture or conditioning basis whenever it materially affects mass balance; do not mix conditioned and as-received masses without a documented conversion. |
| `energy_conversion` | electricity and thermal-energy records | Energy | kWh or MJ | Preserve the invoiced or metered unit and conversion factor; use 1 kWh = 3.6 MJ when conversion is required and do not combine electricity with thermal energy in one exchange. |

## 5. System Boundary

The foreground boundary begins when yarn and any separately purchased dyes, auxiliaries, backing compounds, packaging, water, and energy enter the reporting plant. It includes yarn preparation performed at the plant, weaving, conditional wet processing, conditional backing or coating, drying or curing, cutting, inspection, packing, internal scrap handling, direct emissions, and wastewater leaving the plant. The boundary ends with the net saleable woven floor covering at the plant gate.
