Specifies strength, durability and stability as well as marking requirements for plastic monobloc chairs. This Standard was developed by the Plastics and Chemicals Industry Association in conjunction with the now Australasian Furnishing Research and Development Institute.

This Standard sets out requirements for the evaluation and selection of plastic monobloc chairs for adults but does not include chairs intended for bathroom use. It specifies minimum requirements for strength, durability and stability of the completed chair, but does not account for materials, design, construction or the process of manufacture.NOTES:1 Chairs intended for bathroom and shower use are not covered by this Standard. Chairs in such environments have different requirements due to the hot, wet conditions and the effects of soap. Inclusion of tests in this Standard to cover these conditions would add to the expense of all plastic monobloc chairs, as all chairs would have to be tested whether or not this use was intended. See Section 6 in this Standard for labelling and the Standard for mobile shower/toilet chairs.2 The test results are only valid for the chair tested, therefore if the test is intended to be applied to similar chairs, the test specimen should represent the production model.3 The test results do not ensure that structural failure will not occur.
