between like materials<br />
• Used by manufacturers, buyers,<br />
laboratories and government<br />
• Some standards are mandatory others<br />
provide guidelines for fitness for purpose
Specification or Test Method<br />
• Specifications list a set <strong>of</strong> performance<br />
parameters for a specific purpose (e.g<br />
Upholstery leathers BS EN 13336)<br />
• Test methods do not contain p<strong>as</strong>s fail<br />
criteria (BS EN ISO 4045)
National Standards Bodies (NSBs)<br />
• BSI – UK<br />
