ASTM News The following books have been published by ASTM and are now available:

contains 89 standards of which 37% are new, revised or changed in status since the 1974 edition. New standards include specification for styrene-rubber plastic drain pipe; specification for polyethylene plastics pipe and fittings; and specification for corrugated polyethylene tubing. Part 35 contains 153 standards of which 7% are new, revised or changed in status: new standards include recommended practice for heat ageing of plastics without load; measuring flow rates for pvc and rheologically unstable thermo-plastics. Part 36 has 165 standards, and of the 16% that are new, revised or changed in status, new standards include test for fibre content of reinforced resin composites; test for gel count of plastic film; test for fibre content of unidirectional fibre/polymer composites. ASTM have issued a call for papers for their '4th Conference of Composite Materials: Testing and Design', to be held on May 3 - 4 , 1976 at the Sheraton Valley Forge Hotel, Valley Forge, Pennsylvania, USA. Prospective papers should deal with testing and design of composites to determine their potential
for improving performance or reducing costs in structural applications. Suggested appropriate subjects are: theoretical and experimental studies of static and dynamic properties; time/history/environmental effects - such as creep, creeprupture, fatigue, and thermal cycling; impact and fracture; wear and friction; manufacturing technology; non-destructive evaluation; damage assessment and repair technology; lightning protection; and flight service evaluation. 500-word abstracts with an ASTM offer form should be sent by October 15 to Dr John G. Davis Jr, NASA-Langley Research Center, Mail Stop 188A, Hampton, Va, 23665, USA. ASTM forms can be obtained from Jane B. Wheeler at ASTM. ASTM, 1916 Race Street, Philadelphia, Pa, 19103, USA
Grp helps show the way Fibreglass' Supremat was used in the construction of the cabin for housing radio navigation equipment at an installation in the Shetland Isles, UK (see Fig.3). A doubleskinned, polyurethane foam insulated construction was used to fulfil the customer (Plessey Navaids) requirements of portability, good mechanical and thermal properties, insect resistance and long on-site
~23.75 (countries other than USA, Canada and Mexico, add 5% shipping charges). The opening chapters of the book provide a background to acoustic emission - covering specific characteristics of the signals emitted by structural materials. This is followed bv techniques used and results obtained when commercial and developmental acoustic emission systems were employed to monitor the integrity of a range of engineering structures and components.

Ucrete stops the rot ICI have used their own product 'Ucrete' (cement-modified polyurethane resin) to resolve the problem of renewing industrail flooring where resistance to corrosive attack by chemicals was a major headache. Some 90 m 2 of Ucrete has been used in the filter press section of ICl's azo dyestuffs plant at Huddersfield, replacing the previous floor of granolitic asphalt and Nori tiles set in resin. The use of Ucrete meant that shutdown time was minimised, since the material is quick both to lay and to cure.
The reinforced plastics congress 76 (10th biennial international congress, to be held in Brighton, England, November 8-11, 1976). No overall theme has been given yet: prospective papers therefore are solicited on any aspect of reinforced plastics technology. Synopses should be submitted before September 30 to: Reinforced Plastics Group Executive, The British Plastics Federation, 47 Piccadilly, London W l V 0DN, England.
of topics: it was his work on bulk graphite that led him to investigate the possibilities of graphite as a reinforcement material. He experimented with the pyrolysis of textile fibres, and with the assistance of W. Johnson and L. Phillips was able successfully to produce the first promising carbon fibres having a high degree of preferred crystallite orientation. Within six months of the initial pyrolysis work, carbon fibres with moduli up to 172 GN/m 2 had been produced from polyacrylonitrile fibres.
Retiring pioneer
Bill Watt was awarded the second Charles E. Pettinos Award in 1971 at the 10th Biennial Conference on Carbon at Bethlehem, Pennsylvania for "outstanding and pioneering studies in the preparation of, first, massive specimens of pyrolytic carbon and, second, highly oriented carbon fibres from polyacrylonitrile."
Mr W. (Bill) Watt - one of the pioneers of carbon fibre research at the Royal Aircraft Establishment, Farnborough - has retired after 39 years' service at the Establishment. During his long and distinguished career he was engaged on a variety

Calls f o r papers Calls are issued for the following conferences: Failure modes in composites - III (third biennial symposium, to be held during the 105th AIME Annual Meeting, February 22-26, 1976, in Las Vegas, Nevada). Papers are solicited in the general area of failure modes of composites: subject areas include effects of environment, orientation, processing, fibre, matrix or interfacial bonding on static and dynamic failure. Prospective authors are asked to send 3 0 0 - 5 0 0 word abstracts by September 1st 1975 to either T. T. Chiao - L-421, University of California, Lawrence Livermore Laboratory, Box 808, Livermore, California 94550; or D. M.
