It is very unlikely that this work is public domain in the EU, or in any country where the copyright term is life-plus-70 years. However, it is in the public domain in Canada (where IMSLP is hosted) and other countries where the term is life-plus-50 years (such as China, Japan, Korea and many others worldwide). As this work was first published before 1923 or failed to meet notice or renewal requirements to secure statutory copyright with no "restoration" under the GATT amendments, it is very likely to be public domain in the USA as well.

Wikipedia has 1899 for composition date.
Given its first Vienna performance by the Ševčík quartet on November 22 1905 (composer given as "Rudolf" Glière) - see(Vienna Concerts, early January 1906 publication. Described as first performance, not first performance "in Wien" as with other works on that page, but it seems likely, if not yet proven, that the work was performed elsewhere between 1899 and 1905).
