2.7.1.3.4 Similarly, just because a piece of equipment does not claim conformity to a particular standard, it does not necessarily mean that it is unfit for use. For example, when a revision, i.e. an update, of a standard is published, it does not necessarily mean that equipment that conforms to the old version can no longer be used. This would only be the case if serious safety issues had been detected in products conforming to these earlier standards and/or in the standards themselves. However, if a product has been tested to the most recent version of an appropriate standard, it should give some confidence that it will be safe for its intended use. The same points apply to equipment not conforming to local legislative requirements, e.g. CE marking; OSHA.2.7.1.3.5 Manufacturers should not claim product conformity to draft standards but, in cases where there is no appropriate standard of any kind, this is sometimes the only feasible option. Purchasers should be aware that a draft standard could change.
