Full title and description

ISO 16358-1:2013/Amd 1:2019 — Air-cooled air conditioners and air-to-air heat pumps — Testing and calculating methods for seasonal performance factors — Part 1: Cooling seasonal performance factor — Amendment 1. This amendment provides technical additions and/or corrections to the 2013 Part 1 standard used for determining cooling seasonal performance factors of air‑cooled air conditioners and air‑to‑air heat pumps.

Abstract

ISO 16358-1:2013 specifies methods for testing and calculating the seasonal performance factor (cooling) for equipment covered by reference standards such as ISO 5151, ISO 13253 and ISO 15042. The amendment updates or clarifies test conditions, calculation procedures and mandatory test requirements used for marking, comparison and certification purposes.

Scope

Applies to air‑cooled air conditioners and air‑to‑air heat pumps and specifies the seasonal performance test conditions and procedures for determining the cooling seasonal performance factor (SPF). It is intended for use in marking, comparison and certification; it does not apply to water‑source or water‑cooled equipment, portable units with condenser exhaust ducts, individual assemblies that are not complete refrigeration systems, or equipment using absorption cycles.

Key topics and requirements

• Definition of seasonal performance factor (cooling) and its intended use (marking, comparison, certification).
• Mandatory seasonal test conditions and specified test procedures for measuring performance across a range of ambient conditions.
• Calculation methods for aggregating test results into seasonal performance metrics.
• Applicability statements and explicit exclusions (water‑source/water‑cooled, portable ducted condenser units, assemblies, absorption systems).
• Technical clarifications and corrections introduced by Amendment 1 (2019) to the 2013 Part 1 text.

Typical use and users

Used by test laboratories, HVAC manufacturers, certification bodies, regulatory authorities and energy‑efficiency program administrators to determine, report and compare the seasonal cooling performance of air‑cooled air conditioners and air‑to‑air heat pumps. It is also referenced by designers and consultants involved in product compliance and performance verification.

Related standards

Closely related to ISO 5151, ISO 13253 and ISO 15042 (referenced as the equipment coverage and rating-condition sources). The 2013 Part 1 text has associated corrigenda and amendments (including Amendment 1:2019 and a subsequent Amendment 2 published later). These related documents provide test methods, rating conditions and additional parts of the ISO 16358 series.

FAQ

Q: What is this standard?

A: It is Amendment 1 (2019) to ISO 16358‑1:2013, which updates the Part 1 standard that defines testing and calculation methods for the cooling seasonal performance factor of air‑cooled air conditioners and air‑to‑air heat pumps.

Q: What does it cover?

A: It covers specified seasonal test conditions, test procedures and calculation methods used to derive a cooling seasonal performance factor for applicable equipment, and it lists explicit exclusions (e.g., water‑cooled systems, portable ducted units, absorption systems).

Q: Who typically uses it?

A: Test laboratories, manufacturers, certification and regulatory bodies, energy program administrators, and HVAC product designers and consultants.

Q: Is it current or superseded?

A: ISO 16358‑1:2013 remains the base standard; Amendment 1:2019 is a published amendment to that 2013 edition. The base standard was reviewed and confirmed in ISO records; subsequent amendments (for example a 2024 amendment) have also been issued as part of its amendment history—users should check the latest ISO bibliographic records for the most recent status before relying on the text for compliance.

Q: Is it part of a series?

A: Yes — ISO 16358 is a multi‑part series addressing seasonal performance factors (Part 1 covers cooling SPF); other parts and related ISO documents cover additional aspects and equipment types. Amendments and corrigenda are published against individual parts as needed.

Q: What are the key keywords?

A: Seasonal performance factor, cooling SPF, air‑cooled, air‑to‑air heat pump, testing, calculation, ISO 16358, amendment 2019.
