Full title and description

ISO 8528-1:2018 — Reciprocating internal combustion engine driven alternating current generating sets — Part 1: Application, ratings and performance. This part defines classifications, application categories, ratings and performance descriptors for generating sets consisting of a reciprocating internal combustion (RIC) engine, an AC generator and associated controlgear, switchgear and auxiliary equipment.

Abstract

ISO 8528-1:2018 establishes common definitions and classification rules used to specify generating-set application (continuous, prime, standby, peak shaving, etc.), rating conventions and performance characteristics. It applies to a.c. generating sets driven by reciprocating internal combustion engines for land and marine use and excludes sets used on aircraft or for propelling land vehicles and locomotives. The document is intended as a basis for any supplementary requirements for special applications (for example hospitals or high-rise buildings).

Scope

Specifies application classes, rating methods and performance descriptors for AC generating sets driven by reciprocating internal combustion engines for land and marine installations. It excludes generating sets used on aircraft and those used to propel road vehicles and locomotives. The scope permits the use of the document as a basis for supplementary requirements where higher reliability or special performance is required.

Key topics and requirements

• Definitions and classification of generating-set application types (continuous, limited-time running, emergency/standby, prime, etc.).
• Rated-power and overload conventions, operating conditions and ambient reference conditions for declared ratings.
• Performance descriptors and acceptance criteria to aid manufacturer–customer specification and contract clarity.
• Applicability notes for special installations where supplementary requirements may be necessary (e.g., hospitals, high-rise buildings).
• Guidance on using the part as a basis for other prime movers or for deriving additional project-specific requirements.

Typical use and users

Used by generator manufacturers, engine and alternator suppliers, system integrators, electrical and mechanical designers, procurement/specification engineers, testing laboratories and asset owners to define and agree application class, rated power and performance expectations for generating sets. It is also used as a reference in procurement contracts and conformity documentation.

FAQ

Q: What is this standard?

A: ISO 8528-1:2018 is Part 1 of the ISO 8528 series that defines application classes, rating conventions and performance descriptors for reciprocating internal combustion engine driven AC generating sets.

Q: What does it cover?

A: It covers definitions, classifications of application types (continuous, prime, standby, etc.), rating and overload conventions, performance descriptors and guidance on when supplementary requirements are needed for special installations. It applies to land and marine generating sets and excludes aircraft and traction (propulsion) applications.

Q: Who typically uses it?

A: Manufacturers, specifiers, system integrators, testing labs, design engineers, procurement teams and end users who need a common basis for declaring ratings and performance of generating sets.

Q: Is it current or superseded?

A: ISO 8528-1:2018 is the published (third) edition from February 2018. Users should verify national adoptions or any amendments through their national standards body for the very latest status before procurement or certification.

Q: Is it part of a series?

A: Yes — ISO 8528 is a multi-part series covering engines, alternators, controlgear, generating-set design, test methods and safety (for example, ISO 8528-2, -3, -4, -5, -6, -7, -13). Part 1 provides the common application and rating language used across the series.

Q: What are the key keywords?

A: generating set, genset, reciprocating engine, alternator, ratings, performance, standby, prime, ISO 8528, controlgear, switchgear.
