Overview

EN 1015-9:1999/A1:2006 is a CEN amendment to the European test method for mortar for masonry - Part 9: Determination of workable life and correction time of fresh mortar. It clarifies normative reference wording and updates the test procedure timing for determining how long a fresh mortar remains workable and how long it can be corrected (open/correction time). This amendment was approved in October 2006 and is intended for harmonised national adoption across CEN member bodies.

Key topics and requirements

• Scope: Defines methods to evaluate the workable life (period during which mortar can be placed and compacted) and correction time (period during which surface corrections are possible) of fresh masonry mortars.
• Normative references: The amendment replaces explanatory text with a clear statement that referenced documents are indispensable; for dated references only the cited edition applies, and for undated references the latest edition (including amendments) applies. It also removes all occurrences of the prefix “pr” before EN references.
• Procedure update (Clause 8.2):
  • Adds a precise timing requirement: perform the next step 10 min ± 1 min after completion of mixing.
  • Specifies that a 2 mm to 3 mm thin-layer of mortar is applied as part of the test procedure (the amendment inserts the timing before this application).
• Test focus: Emphasises repeatable, time-controlled evaluation of fresh mortar behavior rather than hardened properties.

Practical applications

• Quality control: Manufacturers of masonry mortars use the method to ensure product consistency and to set practical shelf/use-life recommendations.
• Construction contractors and site managers: Apply test results to schedule work, estimate pot life on-site, and plan corrections to finished surfaces.
• Independent test laboratories: Use the standardised method for certification, performance reporting and comparative testing of mortar formulations.
• Specification writers and compliance officers: Reference EN 1015-9/A1 when drafting performance criteria or procurement specifications for masonry works.

Benefits

• Provides a harmonised, repeatable procedure to assess mortar usability under defined conditions.
• Improves confidence in on-site application planning and reduces waste from prematurely stiffened mortar.
• Ensures consistency across national standards by clarifying reference handling and test timing.

Related standards

• EN 1015 series (Methods of test for mortar for masonry) - consult companion parts in the series for sampling, physical and mechanical test methods.
• CEN/TC 125 “Masonry” publications for broader context on mortar and masonry testing.
