DSS-P.03.02 — Edge Grind / Polish Pattern (factory)

A factory edge-finish pattern produced by belt/diamond grinding and/or polishing after cutting. It can appear-when viewed from the face-as fine, parallel lineation or a narrow glossy/matte band immediately adjacent to the edge. This is a manufacturing edge feature, not a worked-surface defect on the face. Evaluate under VIS inspection lighting/geometry; post-restoration acceptance is governed by VIS and is distinct from factory/product acceptance.

• Uniform, edge-parallel micro-lines (from grinding) or a narrow high-sheen band (from polish) confined to the edge zone.
• Visibility changes with angle and raking light; a Non-Invasive Reveal (clean/dry) does not alter the cue.

Surface-catch class (MSRT):

On the face adjacent to the edge, record SC-0 (none)-one light, non-marring pass only; do not abrade or repeat. The MSRT supports classification only (not acceptance).

Visual signature:

Edge-bound, uniform grind/polish appearance, no transition edge on the face, no chip flanks, no pits/craters. If chip flanks or pits are present on the face, evaluate under M.03/M.04 families by morphology.

Viewing/lighting:

Inspect at 12 / 36 / 72 in with normal incidence and oblique sweep (~60°-120°) using raking light; surfaces must be clean and dry per VIS.

Location/access:

Record surface numbering (#1-#4; laminate-internal) on forms; acceptance pertains to the exposed surface being evaluated.

• Processing feature - not surface damage. If observation confirms uniform factory edge finish with SC-0 on the face and no local worked perimeter → record “Processing Feature - Not Surface Damage (outside CAT-1...CAT-4).”
• Escalate when:
• Face-side micro-chips/clam-shells present with clear catch/bright flanks → classify under M.03 (edge & corner) at CAT-3/4 by morphology.
• Between-pane / inaccessible cues (fixed parallax in IGU) → CAT-5 (location/condition), refer per project protocol.

Factory grind/polish pattern is edge-finish texture; no measurable relief on the face (SC-0) unless accompanied by chips/pits (then classify by morphology rather than assigning numeric depth).

• vs. Abrasion fields on the face (M.02): Abrasion shows directional/web patterning on the face and may produce slight/clear catch; factory edge finish remains edge-bound and SC-0 on the face.
• vs. Fabrication-debris (FD) scratches (M.05): FD marks extend onto the face with linear tracks and may escalate in catch; uniform edge polish does not create face-side tracks.
• vs. Coating anomalies (Co.01/Co.03): Coating rub/patchiness is localized on the worked surface and disallowed at acceptance on coated surfaces; factory edge finish is an edge feature, not a coating change.

• Photo set (VIS): 12 / 36 / 72 in, normal + oblique; include raking usage; capture at least one frame showing long-run edge uniformity to establish factory origin.
• MSRT result: Record SC-0 on the face; one pass only; non-marring.
• Forms: Pane ID; product family and surface numbering; worked surface Y/N; functional coating present on worked surface? (Y/N/Unknown); reveal status; lighting/time; geometry checklist.
• Acceptance split: VIS governs post-restoration appearance; factory edge finishes follow product specs-do not conflate factory features with VIS acceptance.

Attempting to “blend” factory edge polish onto the face can create a worked region with a visible transition edge, which VIS disallows at acceptance (CAT-0...CAT-4). Keep classification appearance-only unless face-side damage is present.

• P.03.02 Edge Grind/Polish Pattern (Processing Feature) - Uniform factory edge finish observed at VIS geometry; MSRT on face = SC-0 (no surface relief). No transition edge or chip-flank morphology on the face. Recorded as manufacturing edge feature; not categorized as surface damage under VIS-DA. If face chips/pits exist, classify under M.03/M.04 by CAT and morphology; if between panes, record CAT-5 and refer per project protocol.
