IS 2046 : Part 8 : 2025/ISO 4586-8 : 2018 Decorative Thermosetting Synthetic Resin Bonded Laminated Sheets - Specification - Part 8 Classification and Specifications for Alternative Core Laminates
NATIONAL FOREWORD
This Indian Standard (Part 8) (Third Revision) which is identical to ISO 4586-8 : 2018 'High-pressure decorative laminates (HPL, HPDL) - Sheets based on thermosetting resins (usually called laminates) - Part 8: Classification and specifications for alternative core laminates' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendations of the Plastics Sectional Committee and approval of the Petroleum, Coal and Related Products Division Council.
This standard was first published in 1962 and subsequently revised in 1969 and 1995. The 1962 version was published to meet the general demand for a standard to cover the use of synthetic resin bonded sheets as a decorative material having a surface which is characterized by its hardness and the materials covered were suitable for use as wall panels or as veneer for wood or other surfaces.
The first revision of this standard was based on BS 3794 : 1964 'Specification for decorative laminated plastics sheets' issued by the British Standards Institution. The second revision was necessitated to harmonize the standard with EN 438-1 : 1991 and EN 438-2 : 1992 issued by the European Committee for Standardization (CEN).
This revision has been brought out to align the Indian Standard to the ISO 4586 (all parts) High-pressure decorative laminates (HPL, HPDL) - Sheets based on thermosetting resins (usually called laminates). Since the ISO standard is published in 8 parts, the standard (IS 2046) has been also bifurcated in 8 parts.
Other parts in this series are:
Part 1 Introduction and general information
Part 2 Determination of properties
Part 3 Classification and specifications for laminates less than 2 mm thick and intended for bonding to supporting substrates
Part 4 Classification and specifications for compact laminates of thickness 2 mm and greater
Part 5 Classification and specifications for flooring grade laminates less than 2 mm thick intended for bonding to supporting substrates
Part 6 Classification and specifications for exterior-grade compact laminates of thickness 2 mm and greater
Part 7 Classification and specifications for design laminates
The text of ISO standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:
a) Wherever the words 'International Standard' appear referring to this standard, they should be read as 'Indian Standard'; and
b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
