kSIST FprEN 13075-2:2026 is a draft European Standard from CEN, published in the SIST collection, for testing bitumens and bituminous binders. It specifies a laboratory method for determining the fines mixing time of diluted cationic bituminous emulsions under standardized conditions, so users can compare breaking behaviour in a controlled way.

The document is aimed at laboratories and industry users who need a reproducible way to measure how a cationic bituminous emulsion behaves when mineral filler is mixed into it. It also includes a safety warning: the user is responsible for identifying hazards, assessing risks, and applying suitable controls before testing.

What does kSIST FprEN 13075-2:2026 specify?

kSIST FprEN 13075-2:2026 specifies one test method for the fines mixing time of diluted cationic bituminous emulsions. The method covers the test principle, reagents, apparatus, sampling, procedure, expression of results, precision, and the test report.

The document is organized into 11 clauses and one normative annex:

Annex	What it covers
Annex A	Characteristics of the reference fillers

The scope is limited to a standardized laboratory determination of fines mixing time. The method uses filler added to diluted emulsion under set conditions, and the result is the time to breaking status.

What are the key requirements of kSIST FprEN 13075-2:2026?

kSIST FprEN 13075-2:2026 is built around a controlled mixing test in which filler is added to diluted emulsion until the mixture breaks. In practice, this means the tester must control sample conditioning, filler properties, mixing rate, and end-point observation closely enough to produce comparable results.

Test principle and end point

Clause 4 states that the filler is added at a uniform rate while stirring. The end point is reached when the mixture becomes pasty, forms lumps that do not adhere to the pan walls, and the stirring power increases noticeably. That end point is the fines mixing time, so the operator must watch the mixture rather than rely on timing alone.

Reference fillers and water

Clause 5 requires analytical-grade reagents and specific reference fillers. The method names Forshammer SE filler, Q92 filler, and Sikaisol filler, and Annex A gives the characteristics each one shall meet. Water shall conform to grade 3 of EN ISO 3696:1995, which matters because the water quality can affect the breaking behaviour.

Apparatus and measuring accuracy

Clause 6 lists the equipment needed, including an oven, stop watch, balance, temperature-controlled bath or chamber, and suitable containers and spatulas. Several items have stated maximal permissible measurement errors, such as temperature, time, and mass control. In practice, this means the laboratory needs equipment that can hold the sample at the right temperature and measure time and mass with enough accuracy for the method.

Sampling and conditioning

Clause 7 requires laboratory sampling in accordance with EN 58 and test sample preparation in accordance with EN 12594. Clause 8 then requires the filler to be dried to constant mass, the emulsion and water to be conditioned at 25 °C for at least 1.5 h, and the test to be run at normal laboratory conditions between 18 °C and 28 °C. This conditioning matters because temperature and moisture affect mixability.

Test procedure and result

Clause 8 specifies the mass of emulsion, water, and filler to be used, the mixing rate of 1 r/s, and the addition rate for the filler. If the emulsion does not break within 300 s, the result is reported as greater than 300 s, including the special case where lumps form but breaking does not occur. Clause 9 says to report each individual value to the nearest second and the final result as the arithmetic mean of the two tests.

Precision and reporting

Clause 10 states that precision data were not available at publication. Clause 11 sets the minimum test report content: sample identification, reference to the document, the filler used, the result and individual values, any deviations, unusual observations, and the test date.

What terms does kSIST FprEN 13075-2:2026 define?

• Fines mixing time - The time in seconds until a mixture of mineral filler and bitumen emulsion shows no noticeable breaking effect under the specified conditions.
• Breaking status - The point at which the mixture becomes pasty, forms lumps, and no longer behaves as a mixable emulsion.
• Reference filler - A specified filler used to perform the test in a repeatable way; the document names Forshammer SE, Q92, and Sikaisol.
• Diluted cationic bituminous emulsion - The test material, made by diluting a cationic bituminous emulsion with water before filler is added.
• Laboratory sample - The sample taken for testing in accordance with EN 58.
• Test sample - The portion prepared from the laboratory sample in accordance with EN 12594 for the actual test.

Who uses kSIST FprEN 13075-2:2026?

kSIST FprEN 13075-2:2026 is used by laboratories testing bitumens and bituminous binders, especially those working with cationic bituminous emulsions. It is relevant to quality control staff, producers, and technical buyers who need a standard way to compare breaking behaviour or check product consistency.

It is also useful in dispute testing, because the method requires the same filler to be used by the laboratories involved. That helps keep results comparable when a result is being checked between parties.

What changed in kSIST FprEN 13075-2:2026 from the previous edition?

The foreword says this draft will supersede EN 13075-2:2016. It also states these changes compared with the earlier edition:

• Clause 5 removes the naming “Caolin” for the Q92 filler.
• Clause 6 updates and revises the apparatus section and uses the metrological concept of maximal permissible measurement error.
• Annex A revises the list of reference fillers and moves Sikaisol to third place.
• Annex A updates and tightens the particle size distribution envelope of the Q92 filler.

Which standards are used with kSIST FprEN 13075-2:2026?

The normative references are:

• EN 58 - sampling bituminous binders, used for laboratory sampling.
• EN 12594 - preparation of test samples, used to prepare the test portion.
• EN 12597 - terminology for bitumens and bituminous binders, used for terms and definitions.
• EN ISO 3696:1995 - water for analytical laboratory use, used to specify the water quality.

The document also points users to related standards and methods in its annexes and bibliography:

• EN 933-1 and EN 933-10 - used for particle size distribution and grading of filler aggregates in Annex A.
• EN 13075-1 - a related breaking-behaviour test for cationic bituminous emulsions.

What does the kSIST FprEN 13075-2:2026 document contain?

The document contains a full laboratory test method, not just a short performance statement. It gives the principle of the test, the materials and apparatus to use, the conditioning and mixing steps, and the rules for reporting the result.

Annex A provides the composition and grading limits for the reference fillers, including text descriptions and figures for the three fillers. Those annex details matter because the filler properties directly affect the measured mixing time, so the filler choice must be controlled if results are to be comparable.
