3) Panel Boards/ Wallboard (GLS-041)

Updated:
22 August 2008

Panel Board/ Wallboard (Interior)

Certification Criteria:

This standard is applicable to a range of panel board products, generally for indoor use such as interior paneling as well as use in further processed products such as furniture. Some of the materials specifically addressed in this standard are:
• Timber, Wood and similar organic fibers
• Gypsum and other minerals
• Plastics
• Glasses (excluding fibreglass products)
• Aluminium
• Steel
• Engineered Wood Products

Products applying under the criterion must comply with the following emissions rates in addition to the material specific criterion that follows:

a) TVOC emission rate of 0.25 mg/ m3 per hour or less after 24 hours, and
b) Formaldehyde emission rate of 0.02 mg/ m3 per hour or less after 48 hours, and
c) 4-phenylcyclohexene < 0.0065 mg/m3 per hour or less after 48 hours,
d) Total Phthalates < 0.01 mg/m³ (Phthalates include dibutyl (DBP), diethylhexyl (DEHD), diethyl (DEP), butylbenzyl (BBP), di-octyl (DOP), and dimethyl (DMP) phthalates)
e) Total Particles < 0.02 mg/m³ (Particles applicable to fibrous, particle releasing products with exposed surface area)

For Timber, Wood and similar organic fibers:

For wood and similar products please follow guidelines under SGL 035 Products Made from Recycled / Renewable Fibers

For Gypsum

a) Gypsum or other mineral panels greater than 5 % of the weight of the product must contain a minimum of 30% recycled content.
b) Gypsum plasterboard shall not be formulated or manufactured with phosphogypsum
