Revised painting preparation Standard just published
Managing the preparation of painting and repainting processes in an effective and systematic way can help ensure the painting result is of a superior quality. It can also ensure the right paint protection is applied to extend the life of painted surfaces and enhance the appearance of painted items.
Standards New Zealand has just published a revised Standard AS/NZS 2311:2009 Guide to the painting of buildings, to update and replace the 2002 version.
This Standard provides guidance and recommended good practice for the design, application, and maintenance of decorative paint systems in the development of painting specifications, and gives choices of paint types for use in different areas. The Standard has been revised to update practices, procedures, and modern paint types.
AS/NZS 2311:2009 can be referred to when specifying the necessary preparation, coating system, and the methods and conditions of application. This Standard can not be nominated as a painting specification, but it can be used as a basis for the preparation of appropriate paint specifications to suit individual contracts.
Furniture fillings – Standards for fitness for purpose
The International Organization for Standardization (ISO) Technical Committee (TC) 45 has produced many Standards for rubber and rubber products, including ISO 5999:2007. Flexible cellular polymeric materials – Polyurethane foam for load-bearing applications excluding carpet underlay – Specification, ISO 5999, plays a key role in the fitness for purpose of furniture items.
ISO 5999 is a powerful tool for ensuring that substandard materials do not enter the marketplace. It provides broad criteria to support manufacturing specifications, materials sourcing, and design. Integration into the manufacturers' quality control systems can help to maximise consumer satisfaction.
Upholstered furniture and bed matresses represent the main use for flexible polyurethane foam. Suppliers of foam components and furniture manufacturers need material specification parameters to give consumers the kind of durability they expect. Foams undergo some softening and thickness loss during extended use because of physical changes within the cellular network, and the Standard uses these for classification.
AS/NZS 3750 Paints for steel structures
AS/NZS 3750.6:2009 Full gloss polyurethane (two-pack)
Specifies requirements for two-component, solvent-borne, full gloss polyurethane paints intended to be used primarily for the protection of iron and steel against exterior atmospheric corrosion. A full gloss polyurethane consists essentially of a polyester, polyacrylate or other polyol based cured with an aliphatic isocyanate hardener and appropriate pigments and solvents.
Supersedes AS/NZS 3750.6:1995.
AS/NZS 3750.9:2009 Organic zinc-rich primer
Specifies requirements for an organic zinc-rich primer intended to protect iron and steel against atmospheric corrosion. It is suitable for application by brush, or spray. Type 2 paint specified in the Standard is referred to in AS 2312 as Paint Reference No. C02.
Supersedes AS/NZS 3750.9:1994.
AS/NZS 3750.11:2009 Chlorinated rubber – High-build and gloss
Specifies requirements for a high-build, chlorinated rubber based, intermediate or topcoat paint and a chlorinated rubber gloss finish paint for the protection of iron and steel against exterior atmospheric corrosion in an industrial or marine environment. The high-build paints are suitable for application only by conventional air or airless spraying, while the gloss paint is suitable for application by brush or spray. Paints specified in this Standard are described in AS/NZS 2312 as Paint References C14 and C25.
Supersedes AS/NZS 3750.11:1996.

DRAFT STANDARD FOR COMMENT
DR 09032 CP Paints for steel structures – Part 7: Aluminium paint (Revision of AS/NZS 3750.7:1994)
Specifies requirements for a single pack bright aluminium finish paint intended to protect iron and steel against corrosion. It may be suitable for application by brush, roller or spray. This paint will provide heat reflectance and medium-term protection from corrosion to suitably primed steelwork located in an industrial atmospheric environment.
