This document describes the procedure for the preparation of test panels from refractory materials by gunning through pneumatic nozzle mixing type guns at ambient temperatures. The test pieces are for the determination of properties on as-gunned products prepared under either “standard conditions” (as required for quality assurance or product development) or “site conditions”. In the case of “…

1 Scope 1.1 Inclusions This Code specifies minimum requirements for the design, construction, installation, operation, inspection, testing, alteration, and maintenance of permanently installed manlifts for the vertical or inclined vertical transportation of authorized personnel and, where authorized, their tools and equipment. Such manlifts are typically installed in grain elevators, radio…

1 Scope 1.1 General This Code specifies minimum requirements for the design, construction, installation, and operation of platform lifts and stair lifts that provide barrier-free access for persons with limited mobility, travelling between fixed points of a building or structure, including a private residence, with a view to safeguarding against risk of accidents associated with the operation…

1 Scope 1.1 Inclusions The requirements specified in this Standard apply to wall and ceiling-mounted track lighting systems intended to be installed in non-hazardous dry locations in accordance with the Canadian Electrical Code, Part I. These requirements apply to a) permanently installed track systems i) rated 347 V or less, 40 A max; ii) supplied by a power source with an output of 30…

Scope Replacement: This International Standard applies to the BASIC SAFETY and ESSENTIAL PERFORMANCE of LIGHT ION BEAM ME EQUIPMENT, hereafter referred to as ME EQUIPMENT, used for treatment of PATIENTS. If a clause or subclause is specifically intended to be applicable to ME EQUIPMENT only, or to ME SYSTEMS only, the title and content of that clause or subclause will say so. If that is not…

Scope This Part 3 of IEC 62109 covers the particular safety requirements for electronic elements that are mechanically and/or electrically incorporated with photovoltaic (PV) modules or systems. Mechanically and/or electrically incorporated means that the whole combination of electronic device with the photovoltaic element is sold as one product. Nevertheless, tests provided in this document…

Scope 1.1 This Standard outlines the principles and general practices of electrical protection applicable to overhead supply systems operating at more than 750 V but less than 50 kV phase to phase and communication systems, where the lines of those systems are located so that inadvertent electric contact between them could occur, resulting in a contact voltage not exceeding a limit agreed…

Scope This part of IEC 60730 applies to automatic electrical air flow, water flow and water level sensing controls for use in, or in association with, boilers with a maximum pressure rating of 2 000 kPA (20 bar) and equipment for general household and similar use including controls for heating, air-conditioning and similar applications. NOTE Examples are water flow and water level…

1 Scope 1.1 Application and material requirements for gas thermal shutoff devices This Standard applies to gas thermal shutoff devices constructed entirely of new unused parts and materials intended for use after the service meter or second stage regulator, hereinafter referred to as “devices”, ranging from 3/8 in (DN 10) up to 6 in (DN 150) nominal pipe size. 1.2 Automatic gas flow shutoff…

1 Scope 1.1 General This Standard specifies requirements for the maintenance of electrical equipment and systems. This Standard applies to new and existing electrical equipment. For new installations of electrical equipment, this Standard can be applied during the early design stages to allow for the implementation of proactive electrical maintenance practices and maintenance safety. 1.2…
