BS EN IEC 60730-2-9-2019 + A2-2020 PDF

Full title and description

BS EN IEC 60730-2-9:2019 + A2:2020 — Automatic electrical controls for household and similar use. Part 2-9: Particular requirements for temperature sensing controls. This British adoption of the EN/IEC text specifies safety, performance and test requirements for temperature-dependent automatic electrical controls (thermostats, temperature limiters, thermal cut-outs and similar) used in household, commercial and related equipment.

Abstract

This standard sets particular requirements (beyond IEC 60730-1) for temperature sensing controls, including constructional rules, electrical safety, endurance and environmental tests, EMC considerations, and special requirements for thermistors and electronic controls. Amendment A2:2020 provides clarifications and additional test procedures (for example, reset behaviour and specific action types) to the 2019 edition. It is intended to ensure safe, repeatable operation of temperature sensing control devices in household and similar applications.

Scope

Applies to automatic electrical temperature sensing controls used in, on or in association with equipment for household and similar use (heating, air‑conditioning, boilers, water heaters, refrigeration controllers, etc.). The standard addresses inherent safety, operating values/times/sequences related to safety, electrical and non‑electrical output devices where relevant, and controls that may be used by the public or in light industrial, commercial or agricultural settings. It does not cover controls designed exclusively for industrial process applications unless specifically referenced.

Key topics and requirements

• Constructional and insulation requirements to prevent electric shock and ensure safe earthing/terminal arrangements.
• Rating, classification and information to be supplied by the manufacturer (rated voltage/current, operating ranges, type classification such as 1.H/2.H, 1.J/2.J actions).
• Mechanical strength, endurance and manufacturing deviation/drift tests to verify reliable operation over life.
• Environmental tests (moisture, dust, temperature extremes, corrosion and heat/fire resistance).
• Specific provisions for electronic controls (Annex H) and for thermistor elements/thermistor‑based controls (Annex J).
• Electromagnetic compatibility (EMC) requirements for emission and immunity where applicable.
• Additional procedural and test clarifications added by Amendment A2:2020 (for example, verification of reset behaviour and test sequencing for certain action types).
• Guidance annexes for application (informative guide) and particular provisions for agricultural confinement building controls (normative annex DD, informative annex EE).

Typical use and users

Manufacturers and designers of thermostats, temperature limiters and temperature sensing controls for household and commercial equipment; test laboratories and conformity assessment bodies performing type testing and routine testing; regulatory and compliance engineers ensuring products meet national/adopted EN‑IEC requirements; quality engineers responsible for product safety and EMC compliance. HVAC, boiler, water‑heater, refrigeration and appliance OEMs commonly apply this standard.

Related standards

IEC 60730‑1 / EN 60730‑1 (general requirements for automatic electrical controls — read together with Part 2‑9), IEC 60335 series (appliance safety standards where controls are used), IEC 61058‑1 (requirements for manual switches not forming part of automatic controls), and other parts of the IEC 60730 series addressing different control types and functions. National adoptions and harmonized standards (EN IEC 60730‑2‑9 and its amendments) should be consulted for conformity evidence.

FAQ

Q: What is this standard?

A: It is the British adoption of EN IEC 60730‑2‑9:2019 amended by A2:2020, giving particular safety and test requirements for temperature sensing automatic electrical controls used in household and similar equipment.

Q: What does it cover?

A: It covers construction, electrical safety, ratings, classification, environmental and endurance tests, EMC, and special requirements for electronic and thermistor‑based temperature sensing controls; it also includes informative guidance on application and specific normative annexes for certain use cases.

Q: Who typically uses it?

A: Product manufacturers (thermostats, HVAC, boilers, refrigeration), test laboratories, conformity assessors, compliance and safety engineers, and standards/quality teams responsible for product certification and market access.

Q: Is it current or superseded?

A: The document BS EN IEC 60730‑2‑9:2019+A2:2020 is the published national adoption (June 2020) of the EN/IEC text with Amendment A2:2020; check national standards bodies or BSI for any later amendments or replacements after this publication date.

Q: Is it part of a series?

A: Yes — Part 2‑9 is one part of the IEC 60730 series (automatic electrical controls). It must be used together with the general requirements in IEC/EN 60730‑1 and other relevant parts and appliance standards where the control is fitted.
