Full title and description

ISO 17962:2015 — Agricultural machinery — Equipment for sowing — Minimization of the environmental effects of fan exhaust from pneumatic systems. This International Standard specifies design principles and test methods intended to minimise release of fugitive dust from seed‑coating material that can be entrained into the intake air of fans (blowers) used on vacuum‑style sowing equipment and then exhausted to atmosphere.

Abstract

ISO 17962:2015 sets out measures and requirements for the design and assessment of fan exhaust on pneumatic vacuum sowing systems where “dust off” from coated seeds can mix with blower intake air and be exhausted. It defines the scope of applicability, exclusions (for example certain central‑tank/remote‑meter conveyance systems) and provides limits and test methods intended to reduce environmental emissions from fan exhaust.

General information

• Status: Published; amended (see Amendment 1, 2021).
• Publication date: July 2015 (Edition 1).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 65.060.30 (Sowing and planting equipment).
• Edition / version: Edition 1 (2015); amended by ISO 17962:2015/Amd 1:2021.
• Number of pages: 8 (main International Standard); Amendment 1 (2021) adds 5 pages.

Scope

This International Standard applies to vacuum‑style sowing systems used for sowing coated seeds where fugitive seed‑coating dust can be drawn into blower intake air and emitted to the atmosphere. It is not applicable to conveyance systems where air is exhausted at remote meters or where the meter is at a central tank and air is exhausted at a ground‑engaging opening device. Design principles in the standard are not intended to be applied retroactively to equipment manufactured before the date of publication.

Key topics and requirements

• Applicability and exclusions for vacuum‑style sowing equipment where seed coating “dust‑off” may be entrained.
• Design principles to minimise environmental release from fan exhaust (location and orientation of exhaust outlets, shielding and routing of exhaust).
• Measured limits for exhaust air velocity and recommended measurement zones to prevent excessive dispersion of fugitive dust (example design constraints and test approach are described in the standard).
• Test methods and verification procedures to assess compliance of fan exhaust arrangements on sowing equipment.
• Guidance on where national or local requirements may be more stringent and should take precedence.

Typical use and users

Manufacturers and designers of agricultural vacuum‑style sowing machinery, test laboratories, regulatory bodies, agricultural equipment certifiers and farm equipment procurement specialists use this standard to design and verify sowing equipment that minimises environmental emissions from pneumatic fan exhausts. Agronomists and field‑safety personnel may refer to it when evaluating equipment for use in environments sensitive to particulate emissions.

Related standards

ISO 17962:2015 is maintained by ISO/TC 23/SC 3 (safety and comfort of agricultural machinery). It was amended by ISO 17962:2015/Amd 1:2021 and has been adopted in the European system as EN ISO 17962:2015/A1:2022. Users should consult the amendment text and any applicable national adoptions for additional or clarified requirements.

FAQ

Q: What is this standard?

A: ISO 17962:2015 is an international standard that specifies measures and test methods to minimise environmental effects of fan exhaust from pneumatic vacuum‑style sowing equipment used with coated seeds.

Q: What does it cover?

A: It covers applicability, exclusions, design principles, measurement zones, limits for exhaust behaviour and test/verification methods to reduce the release and dispersion of fugitive seed‑coating dust via fan exhaust. It does not apply to certain conveyance arrangements and is not intended for equipment manufactured before publication.

Q: Who typically uses it?

A: Equipment designers and manufacturers, test laboratories, conformity assessment bodies, national standards bodies and agricultural purchasers use the standard to design, test and select vacuum‑style sowing machinery with reduced environmental emissions.

Q: Is it current or superseded?

A: The standard was published in July 2015 (Edition 1) and is published and active. It was amended by ISO 17962:2015/Amd 1:2021; the amendment and subsequent European adoption (EN ISO 17962:2015/A1:2022) contain the latest published changes. Consult the amendment text and national adoptions for the most current requirements.

Q: Is it part of a series?

A: ISO 17962:2015 is a standalone International Standard addressing fan exhaust from pneumatic sowing systems; it sits within ISO/TC 23 technical work on agricultural machinery and is related by subject matter to other ISO standards covering machine safety, agricultural equipment performance and environmental considerations. The amendment (Amd 1:2021) is formally linked to the main document.

Q: What are the key keywords?

A: Agricultural machinery, sowing, vacuum seeder, pneumatic fan exhaust, fugitive dust, seed coating, environmental effects, test methods.
