scope. I. These specifications cover high-bitmne.n coal-tar pitch suitable

£or use as a mopping-coat in damp-proofmg or as a plying-cement in

the construction of a membrane system of waterproofing below ground

level, tmder uniionnly moderate temperature conditions both during

the process of installation and during service.

2. The grade of high-bitumen coal-tar pitch covered by these

specitications is suitable for dau1p-proofing and waterproofing founda -

tions, tunnels, subways, etc. ·

S o m p u n1 • SAMPLING
