Scope

Applies to fresh asparagus shoots of commercial varieties of Asparagus officinalis L. offered to consumers after preparation and packaging. The standard is applicable to most asparagus types except: green and violet/green asparagus with diameter less than 3 mm, and white and violet asparagus with diameter less than 8 mm. It covers produce packed in uniform bundles or unit packages and excludes processed asparagus.

Key topics and requirements

• Product definition and commercial classifications for fresh asparagus (varieties and presentation).
• Requirements for quality, sizing and tolerances (including diameter-related applicability/exclusions).
• Sampling and test methods for assessing conformity to the specification (used together with general sampling standards).
• Marking, packaging and labelling requirements appropriate for consumer presentation and trade.
• Procedures for conformity assessment and measurement/tolerance rules associated with the specified test methods.

Typical use and users

Used by asparagus producers, packers and exporters, quality-control and testing laboratories, retail buyers, food regulators and certification bodies to harmonize product specifications, ensure fair trade and provide consistent sampling/test methods for fresh asparagus. The standard supports international trade and commercial quality control for asparagus.

Related standards

Standards commonly referenced alongside ISO 20981 include general sampling and test-method standards for fruits and vegetables (for example ISO 874:1980 — Fresh fruits and vegetables — Sampling) and food-safety/management system standards used by organizations handling fresh produce (for example ISO 22000:2018 — Food safety management systems). National adoptions (e.g., BS ISO 20981:2020) may include national forewords or additional editorial material.
