When selecting stringing tools, always prioritize those that meet or exceed recognized international safety standards and certifications. Key standards and certifications include:

• ISO 9001: Demonstrates a commitment to quality management systems in manufacturing.

• CE Marking (for European markets): Indicates conformity with health, safety, and environmental protection standards.

• ASTM (American Society for Testing and Materials): Many specific ASTM standards apply to materials, testing, and performance of various tools (e.g., for conductor grips, ropes).

• OSHA (Occupational Safety and Health Administration - USA): While not a certification for tools directly, compliance with OSHA regulations is often expected in regions that follow US safety protocols.

• Local and National Regulations: Always verify compliance with the specific safety regulations of the country or region where the tools will be used.

• Manufacturer's Load Ratings: Ensure tools are clearly marked with their Safe Working Load (SWL) or Working Load Limit (WLL) and always adhere to these limits.

• Material and Testing Certifications: Reputable manufacturers provide material certifications and test reports for critical components like ropes, swivels, and grips.
