CAN CSA E598-2-18-98: Luminaires for Swimming Pools and Similar Applications – Technical Overview and Compliance Guide
Ensuring Safety and Performance in Wet Environments Under Canadian Standards
1. Scope and Application
CAN CSA E598-2-18-98 is the Canadian adoption of IEC 598-2-18, which specifies particular safety requirements for fixed luminaires intended for use in swimming pools, paddling pools, fountains, and similar environments where the luminaire is exposed to water immersion or splash. The standard applies to luminaires designed to be installed underwater (e.g., wall‑mounted pool lights) and those in the vicinity of pools (surrounding area lighting). It addresses electrical, mechanical, and thermal hazards unique to wet locations.
Important: The standard excludes portable luminaires, temporary lighting strings, and luminaires covered under other parts of the IEC 598 series (e.g., emergency lighting). It is intended to be used in conjunction with the general requirements of IEC 598‑1 (CAN/CSA‑C22.2 No. 250.0).
2. Technical Requirements
2.1 Protection Against Water Ingress
Depending on the installation location, luminaires must meet minimum ingress protection (IP) ratings. Underwater luminaires (pool lights) require an enclosure rating of at least IPX8, while luminaires located in the zone within 2 meters of the pool edge must achieve IPX5 or IPX7 as specified by the manufacturer. The standard details sealing tests, gasket material requirements, and the need for permanent marking of the IP code.
| Installation Zone | Minimum IP Rating | Test Conditions |
|---|---|---|
| Underwater (pool walls/floor) | IPX8 | Continuous immersion at 1 m depth for 7 days |
| Within 2 m of water (deck, surrounding area) | IPX5 (or IPX7 if possibly submerged) | Water jet (12.5 L/min) or temporary immersion |
| Beyond 2 m from pool edge | IPX4 | Splashing water |
2.2 Electrical Safety
CAN CSA E598-2-18-98 mandates the use of extra‑low voltage (ELV) systems for underwater luminaires, with a maximum rated voltage of 12 V (AC or DC). Additionally, all exposed conductive parts must be reliably connected to a protective earth conductor. Creepage and clearance distances are specified for the primary and secondary circuits, and insulation must withstand 500 V dielectric strength testing. The standard also requires thermal protection for luminaires with built‑in transformers or LED drivers to prevent overheating.
Warning: Underwater luminaires operating above 12 V must undergo additional scrutiny and are generally not permitted under Canadian electrical codes for new installations. Always verify the supply side voltage and isolation.
2.3 Construction and Marking
Materials used in pool luminaires must resist corrosion, UV degradation, and thermal cycles. The standard requires corrosion‑resistant screws, gaskets that maintain elasticity after aging, and cable glands that prevent moisture wicking. Marking must include: manufacturer’s name or trademark, model number, rated voltage and frequency, maximum ambient temperature (Ta), IP code rated, and the symbol for Class III construction if applicable.
3. Implementation Highlights
Manufacturers designing luminaires to CAN CSA E598-2-18-98 must focus on the integrity of the water‑tight seal and the long‑term performance of insulating materials. Practical recommendations from the standard include:
- Use of double‑gasket designs around lens covers and cable entry points;
- Pre‑molded silicone or EPDM gaskets that are replaceable;
- Stainless steel (304 or 316) or marine‑grade brass for hardware;
- Underground cable routing via non‑metallic conduit to avoid stray voltage coupling;
- Marking that is indelible and legible after thermal and UV exposure tests.
Tip: For ease of maintenance, consider designing the luminaire with a quick‑disconnect cord set that allows replacement of the lamp or LED module without breaking the primary water‑seal gasket.
Installers should note that the Canadian Electrical Code (CE Code) incorporates this standard by reference. Bonding of all metal parts in the pool area must comply with Section 68 of the CE Code, and the luminaire’s grounding conductor must be sized accordingly.
4. Compliance Notes for Canada
CAN CSA E598-2-18-98 is a National Standard of Canada endorsed by the Standards Council of Canada. Compliance is mandatory in all provinces when referenced by provincial regulators. While the standard is dated 1998, most current installations reference the newer adoption of IEC 60598‑2‑18 (e.g., CAN/CSA‑C22.2 No. 250.14), but the core requirements remain largely equivalent.
Key compliance steps for manufacturers:
- Obtain certification from an accredited body such as CSA Group, UL (Canada), or QAI;
- Submit technical documentation for construction review, including drawings, material data sheets, and test reports for IP, dielectric, and thermal tests;
- Pass factory production control (FPC) inspection for consistency in sealing and marking.
Success: Luminaires that fully comply with CAN CSA E598-2-18-98 not only meet regulatory requirements but also offer a strong safety record, reducing liability for manufacturers and installers alike.
It is important that certified luminaires carry the appropriate certification mark (e.g., CSA mark) and that any field modifications (e.g., lens replacement with non‑approved parts) void the compliance.
Q: Is CAN CSA E598-2-18-98 still current in Canada?
A: The standard has been superseded by newer editions based on IEC 60598‑2‑18 (for example, CAN/CSA‑C22.2 No. 250.14), but the 1998 edition is still referenced in some legacy installations and is recognized as an equivalent standard for compliance purposes when adopted by provincial authorities.

Q: What is the minimum IP rating for an underwater pool light under this standard?
A: The standard requires a minimum of IPX8 for luminaires installed underwater. This rating must be verified by immersion testing at 1 m depth for 7 continuous days without ingress or damage.

Q: Does CAN CSA E598-2-18-98 allow LED pool lights?
A: Yes, the standard is technology‑neutral. LED luminaires are covered as long as they meet the same construction, thermal management, and electrical safety requirements. However, LED drivers must comply with Class III (extra‑low voltage) requirements if the luminaire is used underwater.

Q: How does this standard relate to the CE Code?
A: The Canadian Electrical Code (CSA C22.1) references these particular requirements in Section 68 for swimming pool lighting. Compliance with CAN CSA E598-2-18-98 is the accepted way to meet the CE Code’s safety mandates for pool luminaires.
