ISO 5435:2008 specifies a method for the determination of the tinting strength of carbon black relative to an industry tint reference black. The method is based on the use of five different commercial instruments. Other instruments may be used if the test results for the standard reference blacks are within the control limits given in ASTM D 4821. NOTE The Densichron reflectometer and…

1 Scope 1.1 This Standard specifies requirements for mineral oil of petroleum origin for use in transformers, oil circuit breakers, or other electrical equipment (excluding high-voltage cables) requiring a liquid insulating and cooling medium. 1.2 In CSA Standards, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with…

1 Scope 1.1 General This Standard specifies a test method for calculating the energy efficiency of external power supplies (EPS) across a full range of load conditions. It covers single-voltage external ac-dc and ac-ac power supplies, which provide one ac or dc output that is at a fixed voltage or user selectable through a selector switch. Note: External power supplies are designed to convert…

1 Scope 1.1 This Standard specifies a test method for determining the energy ratio of devices that charge and maintain secondary batteries. 1.2 This Standard applies to battery-charging systems with (a) battery chemistries such as nickel cadmium, lead acid, lithium ion, and nickel-metal hydride but not primary cell chemistries such as alkaline "dry" cells; (b) a battery voltage less…
