TS EN ISO 8804-2

TS EN ISO 8804-2 defines the minimum training requirements for advanced scientific divers. It addresses the competencies needed to carry out advanced scientific diving in a controlled and effective way, together with the criteria used to evaluate those competencies. In general technical context, scientific diving is a specialised form of diving carried out to support research, observation, sampling, and data collection underwater, where diving skill and scientific purpose must work together.

How advanced scientific diving competencies are organised

The focus of this standard is not just basic underwater proficiency, but the ability to perform more demanding scientific tasks with the right level of preparation and control. Advanced scientific diving typically involves task planning, teamwork, environmental assessment, disciplined data collection, and maintaining scientific objectives during the dive. The evaluation criteria specified by the document are intended to confirm that these competencies have been achieved through training.

The service framework alongside ISO 24803

The document also places the training within a service-delivery framework that is aligned with the general requirements for recreational diving services. In practical terms, this means the training provider is expected to operate within an organised structure covering personnel competence, operational arrangements, and the training environment. The standard therefore connects the specialised needs of scientific diving with a broader service and management context.

• It sets the minimum training requirements for advanced scientific diving.
• It defines criteria for evaluating the required competencies.
• It requires training to be provided in addition to the general recreational diving service requirements of ISO 24803.
• It situates scientific diving training in the context of research, observation, and underwater data collection.
