Описание (английский):

ISO 8254-2:2016 specifies a photometric test method for the assessment of visual gloss by means of a reflectometer value measured at an angle of 75°. It is applicable to plane paper and board surfaces of gloss levels below 65, measured according to ISO 8254-2:2016. It should be the preferred method for paper and board surfaces of gloss levels below 20, measured according to ISO 8254-2:2016. Materials containing optical brightening agents may be measured.

Overview

EN ISO 8254-2:2016 - "Paper and board - Measurement of specular gloss - Part 2: 75° gloss with a parallel beam, DIN method" is a CEN-adopted international standard that defines a photometric method for assessing visual specular gloss of plane paper and board. The method measures a reflectometer value at a 75° angle using a parallel (collimated) beam - commonly known as the 75° DIN method. It applies to surfaces with gloss levels below 65 and is recommended as the preferred method for matt surfaces (gloss below 20). Materials containing optical brightening agents (OBAs) may be measured.

Key Topics and Technical Requirements

Measurement geometry: 75° angle of incidence with a parallel (collimated) illumination beam; detection centered at the specular reflection angle.

Reflectometer principle: The reflectometer value is proportional to the integrated reflection indicatrix within the instrument’s apertures and is scaled relative to a defined specularly reflecting surface (assigned value 100).

Instrumentation components: collimator, decollimator, light source, photoelectronic receptor and sample holder (detailed description in Annex A).

Calibration and standards:

Use of zero-gloss and primary gloss standards for calibration (black glass plate or quartz wedge referenced in the standard).
Working and intermediate gloss standards are used for routine checks; Annex B lists nominated organizations for calibration.

Test conditions and preparation:

Sampling guidance references ISO 186.
Conditioning and atmosphere control follow ISO 187.
Procedures for sample preparation, calibration, measurement, calculation and reporting are specified (see clauses on procedure and test report).

Limitations: Precision data are not provided in this edition; the method is optimized for low-to-moderate gloss levels and is one geometry among ISO 8254 parts.

Applications

Quality control and specification testing in:

Paper and board production (coated and uncoated papers)
Coating operations and converters assessing surface finish
Independent testing laboratories and contract test services
R&D teams developing surface treatments, coatings or optical additives

Use cases include product classification (matt vs gloss), process control, incoming/outgoing inspections, and comparative evaluations where consistent geometry (75° DIN) is required.
