TS EN ISO 8804-1

TS EN ISO 8804-1 defines the minimum requirements for the training of scientific divers and the criteria used to evaluate the competencies needed to undertake scientific diving. Scientific diving is a specialised form of underwater work used for research, observation, sampling, documentation and similar scientific tasks, so the training emphasis differs from recreational diving by focusing on task performance as well as dive control.

Competence-based training for scientific diving

At the centre of this standard is not only the diver’s ability to move safely and effectively underwater, but also the ability to carry out scientific tasks in a consistent and reliable way. In general technical context, scientific divers typically need skills in team coordination, field planning, communication, observation discipline, record keeping and adaptation to changing underwater conditions. The standard also specifies evaluation criteria for these competencies, so the outcome of training is measured performance rather than theory alone.

How it relates to ISO 24803

The standard states that scientific diving training is provided in addition to the general requirements for recreational diving service provision in ISO 24803. In practical terms, this means a provider cannot rely on generic diving-service arrangements alone; scientific work requires additional teaching, practice and assessment tailored to the mission. The standard therefore treats scientific diving as a distinct training context with its own operational and competency profile.

• Minimum requirements for scientific diver training
• Evaluation criteria for the competencies covered by that training
• Additional conditions beyond the general recreational diving service requirements of ISO 24803
