TS ISO 6552/Cor 1

TS ISO 6552/Cor 1 is a technical corrigendum to the ISO 6552 terminology for automatic steam traps. In practical terms, this kind of document is used to tighten wording and align definitions so that the engineering language around steam traps is interpreted consistently. It supports clearer communication about how these devices are named, described, and distinguished in steam-system practice.

What automatic steam-trap terminology covers

An automatic steam trap is a device used in steam systems to discharge condensate and non-condensable gases while retaining live steam as much as possible. Terminology standards help define the meanings of terms such as body, seat, float, thermostatic element, and thermodynamic operating principle. This matters because different steam-trap technologies can look similar in general service but behave differently in how they respond to condensate, air, and steam conditions.

Why a corrigendum matters for users of the standard

As a corrigendum to a parent terminology standard, this document does not introduce a new product category on its own. Its value lies in clarifying the vocabulary used across valve and fluid-system documentation, catalogues, maintenance records, and engineering specifications. In general technical context, consistent terminology helps reduce ambiguity when discussing condensate removal, energy efficiency, and reliable operation in steam networks.

• Concerns automatic devices used in steam systems for condensate and air removal.
• Focuses on technical definitions and naming consistency rather than performance requirements.
• Functions as a corrigendum to improve clarity in the parent terminology standard.
• Sits within the broader language of valves and general fluid-system components.
