ISO 20326:2016 pdf download. Resilient floor coverings — Specification for floor panels/assembly for loose laying.
ISO 20326:2016 specifies requirements and test methods for floor panels/assembly for domestic and commercial levels of use, which have surface layers consisting of resilient floor covering.
ISO 20326:2016 is not applicable to heterogeneous polyvinyl chloride floor panels/assembly for floating installation covered by ISO 10582 or to floor panels/assembly that are subject to frequent wetting, such as bathrooms, laundry rooms and saunas.

B 4.2 Determination of openings between the panels
Using the thickness gauges, measure any openings between the panels at the 13 indicated points without applying any force to the panels.
B.4.3 Determination of height differences
Using the calliper or depth gauge, measure any height differences at the 13 indicated points without applying any force to the panels. Place the base of the instrument at one side of the joint, and measure the maximum height difference at the other side of the joint. Do not carry out the measurement further than 5 mm from the joint edge.
B 5 Calculation and expression of results
calculate the mean value for the thirteen measurements of any openings between the panels and the mean value of the thirteen measurements of any height differences
Record the maximum individual value and the mean value for both properties Express the results in millimetres to the nearest 0.05 mm.
