Full title and description

STB BS ISO 21716-1:2020 — Ships and marine technology — Bioassay methods for screening anti-fouling paints — Part 1: General requirements. This document gives the general requirements and common specifications for preparing and ageing panels coated with anti-fouling paint for use in laboratory bioassay screening tests against specified sessile marine organisms.

Abstract

This part of ISO 21716 specifies common laboratory preparation, conditioning and ageing procedures for test panels coated with anti-fouling paints, and sets out general requirements to ensure reproducible screening bioassays. It is intended to be used together with the test-method parts of the series (for example methods using barnacles and mussels) and applies to anti-fouling paints that act by chemical or biological means; it excludes purely physical foul‑release coatings and methods for ballast-water control.

Scope

This part specifies the general requirements and common procedures for preparing, conditioning and ageing panels coated with anti‑fouling paints to be used in laboratory bioassay screening tests against specified sessile organisms. It applies to anti‑fouling paints that prevent or deter attachment and growth by chemical or biological means. It does not apply to coatings that rely solely on physical foul‑release mechanisms or to anti‑fouling methods intended for ballast‑water or sediment control under IMO ballast‑water rules. Use of this document is intended in conjunction with the part‑specific test methods in the ISO 21716 series.

Key topics and requirements

• Definitions and terminology relevant to bioassay screening of anti‑fouling paints.
• Specifications for preparation of test panels (substrate, coating application, drying/cure conditions).
• Conditioning and ageing procedures for painted panels prior to biological exposure to ensure consistent surface characteristics.
• General requirements for test controls (inert/non‑toxic control panels) and replication to support statistical comparison.
• Guidance on selection of organism groups and reference to part‑specific methods (barnacles, mussels, etc.).

Typical use and users

Typical users include marine coatings manufacturers, R&D laboratories that perform bioassay screening, certification and test houses, regulatory bodies assessing environmental performance of anti‑fouling products, and shipyards or technical teams performing laboratory evaluation of candidate formulations prior to field trials.

Related standards

ISO 21716 is a multipart series; notable related parts include ISO 21716‑2 (barnacles) and ISO 21716‑3 (mussels). The document also refers to related paint‑and‑varnish preparation standards (for example ISO 1513) and other test method parts in the 21716 series.

FAQ

Q: What is this standard?

A: It is ISO 21716‑1:2020 (adopted as BS ISO 21716‑1:2020 in national catalogues), the general‑requirements part of a series of bioassay test methods for screening anti‑fouling paints used in the marine environment.

Q: What does it cover?

A: General procedures for preparing, conditioning and ageing coated test panels and common specifications needed to perform laboratory bioassay screening tests (used with the part‑specific methods that describe exposure to barnacles, mussels, etc.). It excludes purely foul‑release coatings and ballast‑water treatments.

Q: Who typically uses it?

A: Coating manufacturers, independent marine testing laboratories, regulatory assessors, and research groups developing or screening anti‑fouling formulations. Test houses use it to ensure comparability between laboratory screening tests.

Q: Is it current or superseded?

A: Published in 2020 (Edition 1). The ISO listing shows the standard as published and subject to periodic review (systematic review lifecycle), with no indication of being superseded as of the document publication; check your national standards body for the current adoption/status in your country if you need a legally binding or national‑version status.

Q: Is it part of a series?

A: Yes — ISO 21716 is a multipart series (Part 1: general requirements; Parts 2 and 3 specify organism‑specific test methods such as barnacles and mussels). Use Part 1 together with the relevant part‑specific test method.

Q: What are the key keywords?

A: Anti‑fouling, bioassay, screening, test panels, panel preparation, panel ageing, marine coatings, barnacles, mussels, ISO 21716.
