CAN CSA C22.2 No. 62275-16: Cable Ties for Electrical Installations – A Comprehensive Technical Overview

Introduction

CAN CSA C22.2 No. 62275-16, titled “Cable management systems – Cable ties for electrical installations,” is the Canadian adoption of the international standard IEC 62275. Published as part of the CSA C22.2 series under the Canadian Electrical Code (CE Code), this standard specifies requirements and tests for cable ties used to support, bundle, or secure cables and conductors in electrical installations. Compliance with this standard is a key requirement for products intended to be used in Canada, ensuring consistent safety, performance, and reliability across all types of cable tie systems.

Scope and Application

General Scope

The standard applies to cable ties made from metallic or non‑metallic materials that are intended for the management of wiring systems in electrical installations. It covers both reusable and non‑reusable (single‑use) cable ties, including those with integral fixing features (e.g., push‑mount, adhesive mount). The requirements address the mechanical, thermal, electrical, and environmental performance of the ties.

Applicable Installations

CAN CSA C22.2 No. 62275-16 is applicable in all locations where the CE Code demands secure and fire‑safe cable management, including residential, commercial, industrial, and hazardous locations. It is often referenced in conjunction with other CSA standards for conduit, cable trays, and raceways.

Relationship to the CE Code

While the CE Code (CSA C22.1) sets the installation requirements, CAN CSA C22.2 No. 62275-16 provides the product safety criteria. Code Rule 12-110 requires that cable ties used in electrical installations comply with a recognized standard; this publication is the primary standard for that purpose.

Technical Requirements

Materials and Construction

Cable ties must be manufactured from materials that are suitable for the intended environment. For non-metallic ties, polyamide (nylon) 6.6 is the most common material, often with UV stabilizers. The standard prohibits materials that may cause corrosion or galvanic action when in contact with cable jackets, and it limits the content of halogens and other hazardous substances as per RoHS‑type requirements.

Dimensions and Tolerances

The standard defines nominal dimensions for width, thickness, and length, along with allowable tolerances. It also specifies the minimum cross‑sectional area of the locking mechanism to ensure adequate strength. Table 1 below summarizes the primary dimensional requirements for common tie sizes.

Mechanical Performance

Critical mechanical tests include:

• Loop tensile strength – measured on a completed tie around a specified mandrel.
• Insertion force – the force required to engage the locking mechanism.
• Slip resistance – the ability to hold a load without loosening.
• Flexibility – the tie must not crack when bent around a small radius.

All tests are conducted at a controlled temperature of 23 ± 2 °C unless otherwise specified. The standard also includes accelerated aging tests to predict long‑term strength retention.

Flammability and Temperature Rating

Cable ties intended for use in plenums, risers, or air‑handling spaces must meet specific flame‑spread and smoke‑generation limits. The standard references tests such as UL 94 (horizontal/vertical burning) and the Steiner Tunnel test (ASTM E84) where applicable. The ties must be marked with their temperature rating (e.g., –40 °C to +85 °C continuous) and any flame‑classification (e.g., V‑2, V‑0, or HB).

Environmental Resistance

The standard specifies requirements for resistance to:

• Ultraviolet (UV) radiation – for outdoor and sunlight‑exposed installations.
• Moisture and water immersion.
• Chemical exposure (e.g., oils, solvents, acids) – where declared by the manufacturer.
• Heat aging and thermal cycling.

Marking and Documentation

Mandatory Markings

Each cable tie or its packaging must bear the following information:

• Manufacturer’s name or trademark.
• Catalogue or model number.
• Date of manufacture (week/year or lot code).
• Material identification (e.g., PA66, UV‑stabilized).
• Temperature rating and flame class (if applicable).

Manufacturer’s Instructions

The manufacturer must provide installation instructions that include the allowable bundle diameter range, recommended tensile load limits, and any restrictions on reuse. For metallic ties, corrosion protection guidance must be included.

Compliance and Certification

Testing Procedures

Compliance is demonstrated through type tests performed by an accredited laboratory. The tests cover all the mechanical, electrical, thermal, and environmental parameters mentioned earlier. A statistical sampling plan is used to ensure batch‑to‑batch consistency. Manufacturers are required to maintain a quality control program in accordance with ISO 9001 or an equivalent system.

Certification Marks

Products that successfully pass evaluation can bear the CSA mark (or other recognized NRTL marks). The mark confirms that the product meets the requirements of CAN CSA C22.2 No. 62275-16 and any applicable parts of the CE Code.

Ongoing Compliance

Manufacturers are subject to periodic factory inspections and product retesting to ensure continued conformity. Changes in material, tooling, or manufacturing process require re‑evaluation.

Implementation Considerations for Engineers and Installers

Selection Criteria

When choosing a cable tie for a specific application, consider:

• Minimum and maximum bundle diameter.
• Required tensile strength (e.g., when many cables are bundled).
• Environmental conditions (temperature, UV, moisture, chemicals).
• Flame rating needed for the building space.
• Whether the tie is single‑use or reusable.

Installation Guidelines

The standard recommends that installers follow the tensioning instructions provided with the product. Over‑tightening can damage cable insulation and reduce tie strength. For vertical runs, ties should be spaced at intervals not exceeding 1.5 m (5 ft) as per CE Code Rule 12-130.

Compatibility with Other Systems

Metallic ties must be selected to match the environment (e.g., stainless steel for corrosive or high‑temperature areas). Non‑metallic ties shall be UV‑resistant when used outdoors. If multiple tie materials are used in the same system, electrolytic corrosion must be avoided.
