Standards

These guidelines cover the development; implementation, maintenance, and improvement of strategies and system for training that affect the quality of the products supplied by an organisation.

This International Standard provides guidance on engaging people in an organization’s quality management system, and on enhancing their involvement and competence within it. This International Standard is applicable to any organization, regardless of size, type, or activity.

This International Standard provides guidance for project management and can be used by any type of organization, including public, private or community organizations, and for any type of project, irrespective of complexity, size.

This document specifies the organizational context and underlying concepts for undertaking project, programme and portfolio management. It also provides guidance for organizations to adopt or improve project, programme and portfolio management using the standards prepared by ISO/TC 258.

This document is applicable to most organizations, including public and private organizations and it is not dependent on the size and type of the organization. It is also applicable to any project, programme and portfolio, regardless of complexity, size or duration.

Further guidance on project, programme and portfolio management, and the governance thereof, is given in ISO 21502, ISO 21503, ISO 21504 and ISO 21505.

1.1 The requirements of this standard cover holders and connectors for electric lamps, including incandescent, fluorescent, and other electric-discharge-type lamps, rated as indicated in Clause 6, to be used in accordance with the Canadian Electrical Code (CEC), Part I, C22.1, and the National Electrical Code (NEC), ANSI/NFPA 70. 1.2 These requirements cover screw lampholders, including those intended to be mounted directly on an outlet-box, lampholders for special uses, lampholders for electric signs, and adapters that convert one lampholder size to another.

These requirements cover FITTINGS for use with cable and conduit intended for installation in accordance with the National Electrical Code, ANSI/NFPA 70, the Canadian Electrical Code (CEC), Part I, CSA C22.1, and the Standard for Electrical Installations, NOM-001-SEDE. 1.2 These requirements cover CONDUIT LOCKNUTS, conduit BUSHINGS, metal stud BUSHINGS, CONDUIT BODIES, and entrance ELBOWS; FITTINGS for electrical metallic tubing, flexible metal conduit, intermediate metal conduit, liquid-tight flexible conduit, rigid metal conduit, and SERVICE-ENTRANCE HEADS; FITTINGS or box clamps referenced from other standards for armored cable, metal-clad cable, aluminum-sheathed cable, mineral-insulated cable, nonmetallic-sheathed cable, service-entrance cable, and tray cable, and submersible FITTINGS; FITTINGS for flexible cord, flexible nonmetallic and metallic tubing, INSULATING BUSHINGS, grips, reducing washers, and NIPPLES.

This standard specifies the requirements for cord sets and power-supply cords employing molded-on or assembled-on fittings, rated 600 V maximum, and intended for use in non-hazardous locations in accordance with the National Electrical Code, ANSI/NFPA 70. It also specifies the requirements for molded-on general-use attachment plugs and cord connectors etc.

These requirements cover the shielded and no shielded medium-voltage power cables that are described in Tables 1.1 (single-conductor) and 1.2 (multiple-conductor). Multiple-conductor cables may include one or more individually jacketed non-conductive optical-fiber members. These electrical andhybrid electrical and optical-fiber cables are for use (optical and electrical functions associated in the case of a hybrid cable) in accordance with Article 328 and other applicable parts of the National Electrical Code (NEC), ANSI/NFPA 70.

This Standard specifies the requirements for single-conductor and multiple-conductor thermoset-insulated wires and cables rated 600 V, 1000 V, 2000 V, and 5000 V, for use in accordance with the rules of the National Electrical Code (NEC), NFPA 70, in Guyana. See Annex A for the complete list of types and voltage ratings covered by this Standard and the specific electrical codes for which they are intended, and Annex B for a summary of construction and test requirements for these types. Table 1 provides a summary of the maximum conductor temperature, voltage ratings, and the number of insulated conductors for the types to which this Standard applies.

This Standard also specifies the requirements for submersible pump cables, with or without jackets, in Deep Well Submersible Water-Pump Cable, Section 7. No type-letter designations are assigned to these cables.

Products within this Standard might have applications not covered by the electrical codes listed in 1.1.

The requirements in this standard apply to a low-voltage landscape lighting system and components that consist of an isolating type power unit, low voltage cable or flexible cord, and luminaires. The equipment is intended to be installed in accordance with the National Electrical Code, ANSI/NFPA 70,Article 411.1.1 revised February 24, 2014.
