FOREWORD This Indian Standard was adopted bv the Bureau of Indian Standards, after the draft finahzed by the Wood Products Sectional Committee had been approved by the Civil Engineering DIvISIon Council. Cement bonded particle board, which IS now being manufactured 10 our country, is made from a mixture of wo o i part icles a-id cement This standard IS now formulated to provide necessary guidance to the manufacturers and users of this product. In the formulatIOn of thrs standard, considerable assistance has been derived from the folJuwing standards: ISO 8335 . 1987 'Cement -- bonded particle boards - Boards of Portland or equivalent cement reinforced with fibrous wood particles', issued by Inrernatronal Orgarnzanon for Standardization. BS 5669 Part 4 : 1989 'Particle board : Part 4 Specification for cement bonded particle board', issued by British Standards Instrtute. The committee responsible for the the preparation of this standard is given at Annex B Por the purpose of deciding whether a particular rcqurr ement of this standard IS complied with, the final value, observed or calculated, expressing the I esult of a test or analysts, shall be rounded off in accordance with IS 2 : 1960 . Rules for rounding off numerical values (revised)'. The number of srgmficant places retained In the rounded off value should be the same as that of the specified value in this standard.

CEMENT BONDED PARTICLE BOARDSSPECIFICATION
1 SCOPE 1.1 This standard covers the requirements of
cement bonded wood particle boards. 3.7 Cement Bonded Particle Board Particle board made from a mixture of wood particles and portland cement

1.2 This standard does not cover particle boards bonded with synthetic resrn adhesives.

4 MATERIALS
4.1 Species of wood which do not hinder the process of settrng of cement shall be used. Suitable addinv es such as sodium sihcate conforming 10 IS 381: 1972 and aluminium sulphate cotforrmng to IS 260: 1969 shall be used to prevent mhibrtive effect of setting of cement when o thei species are used.
