Standards, Certifications & Class Approval
Review the available standards and approval information relevant to the product. Actual certification, material traceability, inspection and classification requirements depend on the product type, intended application and purchasing specification.
| Applicable Standards & Certification | No universal marine certification normally applies. Accuracy and construction are generally controlled by the manufacturer's specifications; applicable workshop measurement practices may reference ISO 9001 quality systems. |
|---|---|
| Class Approval | Not normally subject to separate DNV, ABS, Lloyd's Register, BV, or ClassNK type approval. Classification requirements may apply to the work performed using the tool, not to the hand tool itself. |
Installation, Maintenance & Safety Information
| Installation Notes | No installation is required. Select a rule length suitable for the work, slide the head to the required position, lock it securely, and verify the tool is clean and undamaged before use. |
|---|---|
| Maintenance Tips | Wipe off salt, moisture, and metal particles after use. Apply a light corrosion-preventive oil to steel surfaces, keep the rule and locking mechanism clean, and periodically check squareness against a known reference. |
| Safety Notes | Use eye protection when marking or working near cutting operations. Do not use the square as a hammer, pry bar, or cutting guide unless specifically designed for that purpose. Secure the workpiece and avoid using a damaged or corroded tool. |
