CE/UKCA

The CE marking indicates that the product complies with the requirements of the EU Personal Protective Equipment Regulation (EU 2016/425). Products are type-examined by a notified body, where their safety and performance are assessed under intended conditions of use.

For drysuits, testing includes, among others:

watertightness
structural durability
user safety

UKCA is the United Kingdom equivalent of the CE marking.

EN ISO 15027

EN ISO 15027-1 defines the performance requirements for constant wear immersion suits intended for use in cold water. The objective of the standard is to delay the onset of hypothermia and extend survival time.

Testing evaluates, among other factors:

thermal insulation in cold water
watertightness
buoyancy and safety performance
mechanical strength

Suits are classified into four thermal performance classes (A–D).

A Class A suit provides protection for up to six hours in 2°C water, while a Class D suit provides protection for at least two hours in 10°C water. Ursuit offers products across multiple thermal protection classes.

SOLAS and MED Approval

The Marine Equipment Directive (MED) defines safety and approval requirements for marine equipment used within the EU. Immersion suits fall within its scope.

The technical basis for approval is derived from the requirements of the International Maritime Organization (IMO) and the LSA Code (Life Saving Appliances), which define performance requirements for life-saving equipment.

SOLAS-approved immersion suits are divided into two thermal performance categories:

Six-hour suit
One-hour suit

SOLAS and EN ISO 15027 approvals are separate regulatory frameworks, although their requirements are partially aligned. A suit may carry both approvals or only one.

SOLAS requirements include high visibility; therefore, approved suits are typically manufactured in bright colours (e.g. orange).

The Red Ensign (wheel mark) is the UK equivalent of the EU MED wheel mark.
