Preface This is the third edition of CAN/CSA-Z241 Series, Park model trailers, which consists of the following Standards: • CAN/CSA-Z241.0, Definitions and general safety requirements for park model trailers; • CAN/CSA-Z241.1, Vehicular requirements for park model trailers; • CAN/CSA-Z241.2, Construction requirements for park model trailers; • CAN/CSA-Z241.3, Plumbing system requirements for park model trailers; • CAN/CSA-Z241.4, Installation requirements for propane appliances and equipment in park model trailers; and • CAN/CSA-Z241.5, Electrical requirements for park model trailers. It supersedes the previous editions published in 2003 and 1992. The purpose of this Series of Standards is to ensure that these recreational living units meet the minimum safety and performance requirements expected by the Canadian market for park model trailers. It is based on the CSA Series of Standards for manufactured homes (CSA Z240 MH) and recreational vehicles (CSA Z240 RV). Significant changes to the individual Standards include the following: a) CAN/CSA-Z241.0: i) new definition for loft; ii) prohibiting the use of lofts; iii) prohibiting the installation of oil fired appliances and equipment; iv) requiring the installation of carbon monoxide detector; and v) new provision for additions; b) CAN/CSA-Z241.2: updated requirements for panel products to reflect new provision for additions;and c) CAN/CSA-Z241.5: additional requirements for branch circuits. This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. These Standards were prepared by the Technical Committee on Park Models, under the jurisdiction of the Strategic Steering Committee on Construction and Civil Infrastructure, and have been formally approved by the Technical Committee. These Standards have been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. They have been published as National Standards of Canada by CSA Group. -------------------------------------------------------------------------------------------------------------------------------- CAN/CSA-Z241.0-18 - Definitions and general safety requirements for park model trailers Scope This Standard provides the definition of the term \"park model trailer\" as used in the CAN/CSA-Z241 Series. It also gives general safety requirements that apply to the other Standards in this Series. -------------------------------------------------------------------------------------------------------------------------------- CAN/CSA-Z241.1-18 - Vehicular requirements for park model trailers Scope 1.1 Requirement specification This Standard specifies vehicular requirements for park model trailers, including minimum requirements for the coupling and the tongue or A-frame, and for the running gear of the trailer. 1.2 Standard application This Standard applies to park model trailers equipped with returnable running gear or limited-use running gear. -------------------------------------------------------------------------------------------------------------------------------- CAN/CSA-Z241.2-18 - Construction requirements for park model trailers Scope This Standard outlines the minimum requirements for materials, products, equipment, and quality of work needed to ensure that park model trailers will provide adequate a) structural strength and rigidity; b) protection against corrosion, decay, insects, and similar destructive forces; c) protection against the hazards of fire; d) resistance to the elements; and e) durability and economy of maintenance. -------------------------------------------------------------------------------------------------------------------------------- CAN/CSA-Z241.3-18 - Plumbing system requirements for park model trailers Scope 1.1 General This Standard specifies the minimum installation requirements and material standards for a plumbing system in a park model trailer. A park model trailer unit may include a kitchen, or a bathroom, or both as optional features and the requirements outlined in this Standard for such features only apply when applicable. 1.2 Disclaimer This Standard is not intended as a design specification or as an instruction manual for untrained persons. -------------------------------------------------------------------------------------------------------------------------------- CAN/CSA-Z241.4-18 - Installation requirements for propane appliances and equipment in park model trailers Scope This Standard applies to the factory installation of propane appliances and equipment in park model trailers. Note: CSA B149.1 and CSA B149.2 were used as a basis for the preparation of this Standard and should be consulted for installations not covered here. -------------------------------------------------------------------------------------------------------------------------------- CAN/CSA-Z241.5-18 - Electrical requirements for park model trailers Scope 1.1 General This Standard applies to the electrical requirements for park model trailers that are intended to be connected by a cord and attachment plug to a source of electrical supply not exceeding 250 V between conductors or 150 V to ground and 50 A maximum in accordance with the Rules of the Canadian Electrical Code, Part I. 1.2 Nonapplicable Types This Standard does not apply to a) travel, camping, and fifth-wheel trailers covered by the CSA Z240 RV Series; b) manufactured homes; c) mobile industrial or commercial structures; d) transportable housing or other structures for use on permanent foundations; and e) the 6 or 12 V battery-operated vehicular lighting and brake wiring systems that are covered by CAN/CSA-Z241.1, provided that the conductors of this system are not in contact or cannot come in contact with the conductors of the higher voltage system. 1.3 Requirements The requirements of this Standard are based on the Canadian Electrical Code, Part I. Where no specific requirements are given, those of the Canadian Electrical Code, Part I, apply.
