ASME PTC 31 - HIGH-PURITY WATER TREATMENT SYSTEMS Organization: ASME
Date: 2011-01-01
Description: This Code is applicable to the following types of highpurity water treatment systems, which are either used individually or in various combinations depending on requirements of the process: (a) membrane equipment including but not limited to, microfiltration, ultrafiltration, nanofiltration, and reverse osmosis (b) ion exchange equipment including, but not limited to, softeners, dealkalizers, multibed demineralizers, mixed-bed demineralizers, and condensate polishers (c) hybrid equipment including, but not limited to, electrode ionization (EDI) and electrodialysis reversal (EDR).
AWS C5.6 - RECOMMENDED PRACTICES FOR GAS METAL ARC WELDING Organization: AWS
Date: 1989-01-01
Description: Further developments to the process included the following: the short circuiting mode of metal transfer (GMAW-S), a lower heat energy variation of the process that permits welding in all positions and also on sheet metal thicknesses; a method using molding shoes to confine the molten weld metal for vertical welding electrogas welding (EGW); and a method of controlled pulsating current (GMAW-P) to provide a uniform spray droplet metal transfer from the electrode at lower average current levels. The GMAW process uses either semiautomatic, machine, or automatic equipment and is principally applied in high production welding.
DS/EN 50050-1 - ELECTROSTATIC HAND-HELD SPRAYING EQUIPMENT - SAFETY REQUIREMENTS - PART 1: HAND-HELD SPRAYING EQUIPMENT FOR IGNITABLE LIQUID COATING MATERIALS Organization: DS
Date: 2013-12-10
Description: All other parts of hand-held electrostatic spraying equipment are considered to be equipment of category 3G if they are installed or used in potentially explosive areas of zone 2.1.4 All other significant hazards relevant for applicators (e.g. ejection of fluids, mechanical strength, electrical hazards (apart from the electrostatic hazards), noise, explosion, contact with or inhalation of dangerous substances, ergonomics) are covered by EN 1953.1.5 This European Standard also gives details regarding quality assurance systems for electrostatic spraying equipment, see Annex C.1.6 Additional requirements may be applicable to equipment designed for use in food and pharmaceutical industry.1.7 This European Standard does not apply to¿ zone classification of the areas in and around spray booths [see EN 12215],¿ zone classification of other areas with potentially explosive atmosphere [see EN 60079-10-1],¿ selection, erection and application of other electrical and non-electrical equipment in areas with explosion hazard [see EN 60079 14 and EN 12215],¿ cleaning of spraying areas, see instruction manual of the spraying equipment,¿ fire prevention and protection, for instance fire hazards due to other sources [see EN 12215],¿ requirements for machinery for the supply and recirculation of coating material under pressure [see EN 12621].1.8 When processing coating materials having specific electrical properties (conductivity, resistivity) the function of the hand-held spraying equipment to charge coating materials electrostatically may be affected as a result of a voltage drop at the charging electrode.
CEI EN 50050-1 - ELECTROSTATIC HAND-HELD SPRAYING EQUIPMENT - SAFETY REQUIREMENTS PART 1: HAND-HELD SPRAYING EQUIPMENT FOR IGNITABLE LIQUID COATING MATERIALS Organization: CEI
Date: 2014-10-01
Description:   When processing coating materials having specific electrical properties (conductivity, resistivity) the function of the hand-held spraying equipment to charge coating materials electrostatically may be affected as a result of a voltage drop at the charging electrode.
MODUK - DEF STAN 03-6: PART 1 - GUIDE TO FLAME SPRAYING PROCESSES PART 1: UNFUSED METAL COATINGS Organization: MODUK
Date: 1972-01-01
Description: (8) For electrical conductivity, wood sprayed with copper for transformer stray current collector rings, plastics sprayed with copper for printed wiring boards, graphite sprayed with copper for furnace electrodes. Thickness of deposit varies according to application.
AA WATP23 - WELDING ALUMINUM: THEORY AND PRACTICE - FOURTH EDITION Organization: AA
Date: 2002-01-01
Description: Arc welding of aluminum was mainly restricted to the shielded metal arc process with a flux-coated electrode which created corrosion problems when the flux was inadequately removed.
IPC-CM-770 - GUIDELINES FOR PRINTED BOARD COMPONENT MOUNTING Organization: IPC
Date: 2004-01-01
Description: Maximum Material Condition (MMC) – A drawing defining certain characteristics of the printed board, such material within the stated limits of size.Metal Electrode Face (MELF) – MELF leadless components have metallized terminals at both ends of a cylindrical body.
