Information from the COIPM Wood Group. Summary received via Mme Dr Anna Gambetta (Italy)
1987 - IRG/WP 4139
Two co-operative programmes were discussed: 1) The IRG/COIPM co-operative programme on the CCA/CCB wood treatments and 2) The IRG/COIPM co-operative programme for testing the resistance of plastic wrapping for wooden pilings. The following was reported: In the wood treatment programme, beech, pine and alstonia wood samples have been pressure treated with 3 retentions (3%, 6% and 10%) of CCA and CC...

Tests on preservation of wood against marine borers
1976 - IRG/WP 417
The Instituto del Legno has carried out for some years a series of trials about the biodeterioration of wood in the sea. The investigations included the settlement and activity of marine borers, the natural durability of indigenous and tropical woods and the preservation of wood for marine use. This paper reports the trials on the effectiveness of some preservatives in protecting wood against mari...

Evaluation of polystyrene as a protective of wood in sea-water
1986 - IRG/WP 4129
A test is described on the biological protection of wood by treatment with polystyrene. The results, obtained in marine trials, after 18 months, show that the treatment with polystyrene is not all that effective in preventing the attack of marine borers....

IRG/COIPM INTERNATIONAL MARINE TEST - to determine the effect of timber substrate on the effectiveness of water-borne salt preservatives in sea-water. Progress Report 9: Report of third inspection (2 years) in Italy
1980 - IRG/WP 461
The wood samples were submerged in the sea at Follonica, Italy, in April 1977. Follonica, latitudine 42°55' North and longitude 10°45' East, is situated on the Tyrrhenian sea. The recorded temperature varies between 13°C to 25°C, salinity 37-38% and pH about 8. The inspections were carried out after 6 months (10/1977), 1 year (4/1978) and 2 years (4/1979)....

Feasibility of microwave disinfestation of wood
1995 - IRG/WP 95-40051
Microwaves have proved to be an effective means to disinfest worm-eaten woods. The use of microwave electromagnetic energy to increase the woodworm temperature to a lethal level presents several advantages with respect to other conventional techniques, such as liquid pesticides and gas chambers. In particular, there is not contamination of the treated wood and of the environment: stray electromagn...

Information from the COIPM Wood Group
1986 - IRG/WP 4130
The Chairman outlined the progress of the co-operative work "testing the resistance to marine borers of heat shrinkable polyolefin sheathings and of wood treated by vacuum/pressure with polymers (polystyrene)". The first part of the work has been started: the samples of wood wrapped with shrinkable polyolefin sheathings have been prepared and sent to the stations participating. The second part of ...

Some observations on the damage to timbers and wooden articles in cultural properties by insects in Italy
1981 - IRG/WP 1135
The damage to cultural properties by insects, especially of wooden material, is a serious problem in Italy. We have carried out a preliminary investigation concerning the most widely distributed and dangerous insects damaging timbers and wooden articles in cultural properties. Up to now the investigation has been carried out in Toscana, Lazio and Emilia Romagna and has concerned some collections o...

Marine trials with water-borne salts and organotin compound
1986 - IRG/WP 4128
Pinus sylvestris blocks treated with water-borne salts (CCA, CCB, CCF) and organotin compounds (TBTO, TBTCl) were submerged in the sea at Follonica station. The results obtained after 12 years of immersion are presented. The samples treated with CCA, CCB and CCF at the lowest concentration (2%) were destroyed after 7-9 years and the samples treated with CCB and CCF at the highest concentrations (4...

List of insects intercepted in imported timbers in Italy
1983 - IRG/WP 1217
The list here reported has been derived from an investigation that the Wood Research Institute in Florence has been carrying out for some years, chiefly in sawmills, in order to verify the presence of wood insects in timbers coming from Europe, Africa, Asia, America (North, Central and South). Italy imports a great lot of timbers; during 1980, 1,320,000 m³ of logs and 495,000 m³ of sawnwoods hav...

During the last COIPM Meeting, up to date information on cooperative work to test the resistance of plastic wrapping for pilings were submitted and discussed. In 1986 untreated wood samples wrapped with shrinkable polyolefin sleeves were submerged in 9 stations, situated in temperate and tropical waters. After 1 or 2 years of immersion the samples showed no sign of penetration by marine borers and...
