^{^{.^{^a}}}	Rating Scale (Blue Wool standard No. 6):
	> 6, 6, and < 6
.^{^b}	Rating Scale (according to EN standard):
		Degree 5 - Decorative surface unchanged from as received condition no hairline cracks.
		Degree 4 - Hairline cracks only visible under 6x magnification, irregularly distributed across the
		surface.
		Degree 3 - In addition to degree 4 faults, cracks (normally parallel to the short edge of the specimen)
		visible to naked eye, corrected if necessary.
		Degree 2 - A gaping crack which may extend right across the specimen.
		Degree 1 - Specimen broken into separate parts.
.^{^c}	Rating scale (according to NEMA standard):
		0 - No attack
		1 - Slight attack
.^{^d}	Rating scale (according to EN standard):
		Degree 5 - No visible change.
		Degree 4 - Slight change of gloss and/or colour, only at certain viewing angles.
		Degree 3 - Moderate change of gloss and/or colour.
		Degree 2 - Heavy change of gloss and/or colour.
		Degree 1 - Surface distortion, blistering and/or delamination.
.^{^e}	Rating scale (according to British standard):
		1 - No effect after 16 hour.
		2 - No effect if completely removed within 10 - 15 minutes.
		3 - Surface attack and/or staining probable, necessitating immediate removal.
