FprEN ISO 17966 is a CEN draft European standard for assistive products for toileting, bathing and showering. It specifies safety, functional, ergonomic requirements and test methods for products intended by the manufacturer to alleviate or compensate for disability, and it also takes assistants into account where their use is part of normal operation.

In practice, FprEN ISO 17966 is the document used to design, test and describe commode chairs, toilet seats, shower chairs, bath boards, grab rails and related products. It covers normal use, foreseeable misuse and failure, and it includes both general requirements and product-specific test methods.

What does FprEN ISO 17966 specify?

FprEN ISO 17966 specifies requirements and associated test methods for assistive products for toileting, bathing and showering that are treated as medical devices in some jurisdictions. It also sets out requirements for safety, performance, ergonomics and the work environment and safety of assistants.

The document is organized into a general part and product-specific clauses, followed by information, packaging and reporting requirements. The main structure runs from Scope and Normative references through Terms and definitions, then general requirements, materials, noise, electromagnetic compatibility, electrical safety, liquid ingress, temperature, moving parts, fall prevention, entrapment prevention, lifting, strength, stability, ergonomics, mobile products, fixed products, portable products, manufacturer information, packaging and test reporting.

Annexes give guidance and special topics used alongside the main requirements.

AnnexWhat it covers
Annex ACognitive impairment
Annex BGeneral recommendations
Annex CEnvironmental and consumer-related requirements
Annex DPeriodic inspection
Annex ELithium batteries
Annex ZARelationship with Regulation (EU) 2017/745 General Safety and Performance Requirements

The scope names product families from EN ISO 9999:2022 such as commode chairs, toilets, toilet seats, raised toilet seats, bath boards, bath seats, shower chairs, bathing stretchers, wash basins, bidets, handrails and grab rails. It also states exclusions for building structure fixing, fixed building utilities and some other product types.

What are the key requirements of FprEN ISO 17966?

FprEN ISO 17966 combines risk management, clinical evaluation, mechanical safety and user information. The most important requirements are the ones that decide whether a product is safe to use, whether it can carry the intended load and whether the manufacturer has documented that use clearly.

Risk, intended performance and clinical evidence

Clause 4.1 requires risk analysis using EN ISO 14971 and, where relevant, EN ISO 12100. The analysis has to consider users, assistants and third persons around the product. In practice, this means the manufacturer must identify hazards from normal use, foreseeable misuse and failure before the product is released.

Clause 4.2 requires intended performance to be backed by sufficient strength and durability, supported as appropriate by literature, calculations and test results. That matters because the manufacturer has to state what the product is for, what loads it can handle and under which conditions it remains fit for use.

Clause 4.3 requires a clinical evaluation for all assistive products, and any clinical investigation has to follow EN ISO 14155. For buyers and quality teams, that means clinical justification is part of the conformity picture, not an optional extra.

Dismantling, fasteners and load limits

Clauses 4.4 and 4.5 address products that can be dismantled for storage, transport or cleaning. Reassembly must not create an unacceptable risk, and load-bearing fasteners must not be single-use fasteners. In practice, products that come apart for cleaning or transport need a design that still locks together safely after repeated assembly.

Clause 4.6 requires declaration of maximum user mass, and maximum load where it differs, plus minimum user mass where needed for function. Products intended to support a seated or lying user must support at least 100 kg body mass. This is a practical design and purchasing point: the stated load rating has to match the intended user group, and the product must be visibly limited if it is meant for lower body masses.

Materials, hygiene, corrosion and sound

Clause 5 requires material suitability, including biocompatibility assessment for body-contacting materials using EN ISO 10993-1. It also asks the manufacturer to reduce risks from substances that may leak from the product, including substances of very high concern, and to consider cleaning, disinfection and corrosion.

Clause 5.5 requires corrosion risk assessment and allows salt spray testing to EN ISO 9227 when corrosion is a safety risk. That matters for products used in wet bathroom environments, where corrosion can affect strength, movement or hygiene.

Clause 6 covers noise and vibration. If noise is not part of intended performance, it must still be considered as a hazard or nuisance, and noise measurements for powered products are taken using EN ISO 3746. Audible warning devices also have frequency and sound-level expectations. For users with hearing loss, this affects whether alarms are actually noticeable.

Electrical safety, liquid ingress and temperature

Clause 7 requires electromagnetic compatibility (EMC) for products with electrical or electronic parts. Clause 8 applies electrical safety requirements, including home healthcare use where relevant, battery charge indication when safety depends on internal power, and specific requirements for pendant controls and heated flexible appliances.

Clauses 8 and 9 also address ingress of liquids and particulate matter, overflow and leakage. Bathroom products often operate near water, so the standard asks the manufacturer to control the risk that liquid entry or leakage creates a hazard.

Clause 10 sets surface-temperature control for parts that touch human skin. The product has to be assessed for ambient conditions, fault conditions and contact duration. If surfaces may become hot, the manufacturer may need warnings and precautions in the instructions for use.

Moving parts, entrapment and fall prevention

Clauses 11, 12, 13 and 14 cover moving parts, folding parts, trapping zones, side rails and locking mechanisms. The product must avoid finger, foot, head and genital entrapment, either by guards or by maintaining safe gaps. Folding and adjusting mechanisms must lock securely and resist unintended release.

Clause 12 requires measures to prevent the user falling out where that risk exists. For lying support surfaces, side rail height depends on whether the patient is left unattended. Clause 13 requires safe clearances for holes and stationary gaps, and the user group has to be specified so the correct distances are applied.

Lifting, handling, drops and durability

Clauses 15 and 16 address lifting and carrying means, and portable or hand-held products or parts. Handles and grips must withstand a defined force test, and portable items must survive free-fall testing from a height based on mass. That matters for transport, installation and day-to-day handling by carers.

Clause 17 is the main mechanical strength section. It covers static strength, durability and impact, gives formulae for calculating test forces, sets the number of durability cycles from expected lifetime, and provides product-specific load and impact methods. For procurement and quality control, this clause is where product robustness is verified.

Clause 18 tests stability of mobile and portable products at forward, backward and sideward tilt angles under maximum load. Clauses 19 and 20 deal with smooth surfaces, protruding parts and choking hazards for children. Clause 21 requires the risk from forces in soft tissues of the human body to be assessed, which is relevant to pressure and discomfort risks.

Ergonomics, mobility and fixed or portable product families

Clause 22 gives ergonomic requirements for handles, pedals and controls, including operating forces and placement. This is the clause that links the product to real-world usability by people with disability and by assistants.

Clauses 23 to 25 add product-family-specific requirements for mobile, fixed and portable assistive products. They cover brakes and locking devices, rough handling, movement over thresholds, push-handle position, turning diameter, stability on bathtub rims, bracket strength, slip resistance, and specific tests for raised toilet seats, bath boards, stools, back supports and seats.

Manufacturer information, packaging and reporting

Clause 26 requires instructions for use, pre-sale information, user information, service information and labelling. Clause 27 requires packaging to be assessed for protection during storage and transport. Clause 28 defines the minimum content of the test report, including sample identification, test conditions, results, deviations and pass-fail statements.

What terms does FprEN ISO 17966 define?

  • Applied part - the part of the device that necessarily touches the user in normal use in order to perform its function.
  • assistant - the person who helps a person with disability use the assistive product.
  • assistive product - a product that improves functioning and reduces disability, including devices, instruments, equipment and software.
  • fixed assistive product - a product designed to be fastened or secured in one place, either by shape or by fasteners.
  • movable mobile assistive product - equipment that is intended to be moved from one place to another while supported by its own wheels or equivalent means.
  • movable portable assistive product - equipment that is used with the user in place only when stationary and can be moved without the user in place.
  • foreseeable misuse - wrongful use that can reasonably be anticipated.
  • intended use - the use intended by the manufacturer in accordance with the product specifications, instructions and information.
  • maximum user mass - the greatest user weight the manufacturer says the product is intended to support.
  • maximum load - the greatest permissible weight on the product or a product part during normal use.

Who uses FprEN ISO 17966?

FprEN ISO 17966 is used by manufacturers of bathroom and toileting assistive products, design engineers, test laboratories, risk managers and quality teams. It is also relevant to clinical evaluators, regulatory teams and buyers who need to compare products against the same safety and performance basis.

The standard is especially relevant in home care, healthcare and sanitary-installation settings where products are used by disabled people and by assistants. It helps teams decide what to design, what to test, what to document and what to state in instructions for use and labelling.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this doc
