This document specifies requirements for classification of covered electrodes, based on the all-weld metal chemical composition, the type of electrode covering and other electrode properties, and the all-weld metal mechanical properties, in the as-welded or heat-treated conditions, for manual metal arc welding of stainless and heat-resisting steels. This document is a combined standard providing…

This document specifies acceptable criteria for microbiological cleanliness and adequacy of preservation of the specified toy materials. The requirements in this document apply to all toys that are, contain or are supplied with aqueous materials (e.g. paste, putty, liquid or gel). In addition, this document applies to toys that are or include a cosmetic (including those intended for use on a toy…

1 Scope 1.1 This Standard applies to deadfront indoor enclosed and outdoor enclosed assemblies of switchgear devices such as a) switches; b) interrupting devices; c) air circuit breakers; d) power circuit breakers; and e) control, metering, protective, and regulating equipment with associated interconnections and supporting structures. 1.2 This Standard covers equipment with a…

This document prescribes requirements for the classification of nickel and nickel-alloy covered electrodes for manual metal arc welding and overlaying. The classification of the covered electrodes is based on the chemical composition of their deposited all-weld metal. It includes those compositions in which the nickel content exceeds that of any other element.

This document provides three shoe size conversion tables covering the major shoe sizing systems (Mondopoint, European and United Kingdom), as well as China, Japan, the Republic of Korea and United States. The tables are based on measurement of foot length, this being the logical starting point for any shoe size marking system. The tables contain the following information: Table 1 — Adults’…

This document specifies a method to evaluate the capability of portable household air cleaners to reduce the concentration and viability of key experimentally generated bioaerosols in a specified chamber. Indoor air free of harmful microbes is important to the health of occupants. This is particularly relevant with regard to increased time spent indoors. Air cleaners are used to reduce the…

1 Scope 1.1 General This Standard specifies a test method for calculating the energy efficiency of electric vehicle supply equipment (EVSE) for direct current fast charging (DCFC) across a full range of load conditions. It defines operating modes, and provides energy efficiency minimum requirements for these operating modes. Note: Many owners and operators of DCFC are concerned with the amount…

Scope 1.1 These requirements apply to speakers, rated at 300 V or less, for fire alarm and signaling systems intended for indoor and/or outdoor installation: a) In Canada only: in accordance with CSA C22.1, Canadian Electrical Code, Part I, Safety Standard for Electrical Installations, and with ULC-S524, Standard for Installation of Fire Alarm Systems. b) In the United States only: in…
