SSPC-VIS 4 / NACE VIS 7 | Waterjetting Visual Guide

TUTORIALS

SSPC-VIS 4 / NACE VIS 7 is a visual reference guide designed to assist in the assessment of steel surfaces prepared by high- or ultra-high-pressure waterjetting prior to the application of paints and protective coatings.

The guide provides reference photographs that allow actual surface conditions to be compared with recognized visual standards, supporting a more objective assessment of the cleanliness achieved by waterjetting.

During inspection, the guide can be used to identify the initial surface condition and assist in evaluating the different levels of cleanliness established by SSPC/NACE waterjetting standards.

FUNCTION DETAILS

Visual Reference for Waterjetting
Provides reference photographs for comparison with steel surfaces prepared by waterjetting.

Initial Surface Condition Assessment
Assists in visually identifying the condition of the surface before cleaning begins.

Cleanliness Level Assessment
Allows the prepared surface to be compared with visual references associated with different waterjetting cleanliness levels.

WJ-1 to WJ-4 Reference
Supports inspections associated with WJ-1, WJ-2, WJ-3 and WJ-4 cleanliness levels according to the project specification.

Reduced Subjectivity
Comparison with standardized photographs helps improve consistency between inspectors, applicators and owners.

Professional Use
Suitable for surface-preparation inspection, industrial coating, maintenance, shipyards, steel structures and quality-control applications.

APPLICATIONS

Visual assessment of waterjetted surfaces;
Inspection of waterjetting processes;
Assessment of WJ-1, WJ-2, WJ-3 and WJ-4 cleanliness levels;
Quality control prior to coating application;
Inspection of steel structures and metallic surfaces;
Training and personnel qualification;
Audits and technical surface-preparation records.

Recommended for coating inspectors, surface-preparation professionals, engineers, technicians, waterjetting contractors, service providers, shipyards and industries requiring visual assessment of steel surfaces prepared by waterjetting.

DOCUMENTS

SSPC-VIS 4 / NACE VIS 7 should be used as a visual supplement to the written requirements of the applicable waterjetting cleanliness standards. Always refer to the current SSPC/AMPP/NACE standards and project specifications to determine surface acceptance criteria.

REPLACEMENT PARTS
