Frequently Asked Questions about Hazard Classification:

What is hazard classification testing, and why is it important?

Hazard classification testing is a process used to determine the potential hazards associated with a substance or product. Hazard classification testing contributes to ensuring the safety of workers and consumers, by providing accurate information about the potential risks associated with a substance or product. It also aids in compliance with local, regional, and international regulations governing the use and distribution of hazardous materials.

Why is it important to use an ISO17025 accredited laboratory for hazard classification testing?

Hazard classification testing by an ISO 17025 accredited laboratory ensures accurate, validated, and traceable results. It guarantees competent staff, impartiality, and adherence to international standards. Regular audits maintain quality, enhancing regulatory compliance and global recognition. Choosing an accredited lab builds trust and confidence in reliable hazard assessment for products and safety. 

Additionally, some large e-Commerce retailers require ISO accreditation for listings. Dell Tech is an Amazon approved testing lab.

What standards are followed for hazard classification testing?

Test methods are often prescribed specifically by a regulation that applies to the product. If not specified, recognized standards are used. Common standards include ASTM International, OECD (Organization for Economic Co-operation and Development), United Nations Manual of Tests and Criteria, and Health Canada Official Methods.

How long does hazard classification testing typically take?

The duration varies based on the specific test and material. Our team of experts can provide estimated timelines once they understand your requirements.

What can the results of hazard classification testing be used for?

Hazard classification test results serve several critical purposes:

  • Regulatory compliance – hazard classification informs labeling, packaging, transportation, shipping and handling requirements.
  • Legal and liability considerations – Accurate hazard classification supports legal compliance and liability management, reducing the risk of legal disputes or penalties.
  • Safety Data Sheets (SDSs) – Classification data is used in authoring safety data sheets accurately.
  • Product design and improvement – Test outcomes guide material and product design, promoting the development of safer alternatives and innovative solutions to reduce hazards.
  • Risk assessment – Results inform risk assessments for workers and consumers, helping to develop strategies to mitigate potential risks and establish safe usage guidelines.
  • Supply chain management – Manufacturers, suppliers, and distributors use hazard classification to ensure safe transportation, storage, and distribution of hazardous substances.
