Household and similar electrical appliances - Safety - Part 2-41: Particular requirements for pumps
Scope:
IEC 60335-2-41:2024+AMD1:2026 CSV deals with the safety of electric pumps for liquids having a temperature not exceeding 90 °C, intended for household and similar purposes, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances including direct current (DC) supplied appliances and battery-operated appliances. Examples of appliances within the scope of this standard are
- aquarium pumps;
- garden pond pumps;
- shower-boost pumps;
- sludge pumps;
- submersible pumps;
- table fountain pumps;
- vertical wet pit pumps.
Appliances not intended for normal household use, but that nevertheless can be a source of danger to the public, such as appliances intended to be used by laymen in shops, in light industry and on farms, are within the scope of this standard.
As far as is practicable, this standard deals with the common hazards presented by ap-pliances that are encountered by all persons in and around the home. However, in gen-eral, it does not take into account
- persons (including children) whose physical, sensory or mental capabilities; or lack of experience and knowledge prevents them from using the appliance safely without supervision or instruction;
- children playing with the appliance.
Attention is drawn to the fact that
- for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements can be necessary;
- in many countries additional requirements are specified by the national health authori-ties, the national authorities responsible for the protection of labour and similar au-thorities.
This standard does not apply to
- stationary circulation pumps for heating and service water installations (IEC 60335-2-51);
- pumps for flammable liquids;
- pumps intended exclusively for industrial purposes;
- pumps intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas);
- pumps incorporating chlorinators of the electrolytic type.
Pumps incorporated in appliances are not covered by this standard unless a specific ref-erence is made.
This fifth edition cancels and replaces the fourth edition published in 2012. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) alignment with IEC 60335-1:2020;
b) modification or conversion of some notes to normative text (Clause 1, 7.12.1, 25.7);
c) introduction of IEC 60417 symbol for maximum operating depth and indoor use only (7.1, 7.6, 7.12.1);
d) clarification of requirements for aquarium pumps and garden pond pumps;
e) addition of legibility requirements for markings exposed to solar radiation (7.14);
f) clarification of pumps subjected to test probe 18 (8.1.1, 20.2);
g) introduction of accessible surface temperature limits (Clause 11);
h) addition of requirements for IEC 61984 connectors for pumps intended for permanent connection to fixed wiring (22.107, 24.1.5, 24.1.101, 25.3).
i) clarifications on remote operation for pumps in scope of this standard (22.40, 22.49, 22,51).
This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its amendments unless that edition precludes it; in that case, the latest edition that does not preclude it is used. It was established on the basis of the sixth edition (2020) of that standard.

This document specifies the construction characteristics, performances and marking related to safety and the rational use of energy of portable, flat gas appliances directly supplied at the LPG vapour pressure, incorporating a gas cartridge complying with EN 417:2012, inserted horizontally in the chassis.
NOTE 1 These appliances are referred to in the body of the text as “appliances”.
This document covers appliances for outdoor or in well ventilated areas uses only.
This document does not cover appliances supplied by an external gas source.
For example, the following types of appliances are covered:
a) cooking appliances (stoves, barbecues);
b) heating appliances.
This document specifies the requirements applicable to these appliances or their functional sections whether or not the latter are independent or incorporated into an assembly.
Appliances covered by this document are not connected to a flue for the discharge of products of combustion and are not connected to the mains electricity supply.
This document covers neither appliances supplied with LPG in the liquid phase nor appliance with fixed integral container which could be refilled by the user.
This document does not cover appliances of direct pressure propane category.
Requirements for rational use of energy have been considered for stove burners.
NOTE 2 However, such requirements have not been considered for the other types of appliances because:
- for barbecues, this type of cooking varies according to the type of food and region where the appliance is used;
- for heating appliances, all the heat produced is discharged into the environment.

Plastics piping systems - Polyethylene (PE) valves - Test method for resistance to thermal cycling
Scope:
This standard specifies a test method for the evaluation of leaktightness of a valve under pressure while it is under external thermal cycling.
This standard is applicable to polyethylene (PE) valves and valves with PE spigot-ends having a nominal outside diameter greater than 63 mm and intended for the transport of fluids.
For diameters equal to or lower than 63 mm EN 1704 is applicable
When specified in the product standard, this document can be applied to valves of material other than PE.

Industrial valves - Metallic diaphragm valves
Scope:
This document specifies minimum requirements applicable to design, final assessment, designation, marking and documentation for diaphragm valves:
- having unlined and lined metallic bodies;
- having weir, weirless and straight-through body designs;
- for operation with manual handwheel or actuator;
- for use with flanged, welded and threaded pipe end connections;
- used for isolating, regulating or controlling applications or any combination thereof.
The PN and Class ranges are:
- PN 6, PN 10, PN 16 and PN 25;
- Class 125 and Class 150.
The size range is:
- for flanged valves: sizes DN 15, DN 20, DN 25, DN 32, DN 40, DN 50, DN 65, DN 80, DN 100, DN 125, DN 150, DN 200, DN 250, DN 300, DN 350, DN 400, DN 450 and DN 500;
- for screwed valves: sizes NPS ¼, ⅜, ½, ¾, 1, 1¼, 1½, 2, 2½ and 3;
- for weld end valves: sizes DN 8, DN 10, DN 15, DN 20, DN 25, DN 32, DN 40, DN 50, DN 65, DN 80, DN 100, DN 125, DN 150 and DN 200.
NOTE 1 Sizes are listed in Table D.1.
This document applies to metallic diaphragm valves used for all industrial applications.
For applications in accordance with the European legislation for pressure equipment, EN 16668:2025 applies together with this document.
Additional requirements given in the relevant application standards can apply to diaphragm valves used for more specific applications (e.g. for the water industry, the chemical and petrochemical process industry).
For chemical and petrochemical applications, EN 2569:2020 apply together with this document.
For water supply applications, EN 1074-1:2000 and EN 1074-2:2000 apply together with this document.
NOTE 2 National potable water approval schemes (WRAS, DVGW, ACS, etc.) can apply in addition to the valve design standards.
For process control applications, EN 1349:2009 and EN 60534-2-1:2011 apply together with this document.
For cryogenic applications, EN 1626:2008 apply together with this document.
For fire-safe applications, EN ISO 10497:2022 apply together with this document.
For fugitive emissions applications, EN ISO 15848-1:2015+A1:2017 and EN ISO 15848-2:2015 apply together with this document.
Other specific application standards, regulatory requirements, purchaser specifications or national approval schemes can also exist and can apply depending on the intended service, installation location, fluid, pressure/temperature conditions and end-use application.
