SCOPE

1. The technical requirements for the production of calcium silicate filling compound for usewithin the temperature range of 80° C to 650° C, but for continuous service a temperature of550° C is not to be exceeded. The calcium silicate filling compound is for use with thermalinsulation in HM Surface Ships and Submarines.

2. The material is commonly known as calcium silicate ‘plastic’ compound in the thermalinsulation industry.

d. Before a manufacturer is accepted as a supplier of material to this NES he is tosupply to the Approving Authority or the Ministry’s adviser on occupationalhygiene, full particulars of the chemical constituents of the finished materialtogether with any other information necessary to enable an assessment of theoccupational hazard to be made. For fibrous components, information on thefibre dimensions is also to be supplied. When the material is intended for usein HM Submarines additional information will be sought to enableconsideration to be given to any harmful effect the material may have on theclosed environment of the submarine. Any such information will be treatedstrictly in confidence.

e. Recommendations for the safe handling of the material are to be provided.

f. In selecting materials or substances to meet this NES the manufacturer is totake into account their relative toxicity or health hazard. Preference will begiven by DCW to those materials which, while meeting the technicalrequirements of this NES, create the least hazard in their storage, handling,application, removal and disposal.

g. If any change is made in the formulation of the material after initial acceptancefull particulars of the changes are to be supplied to the Approving Authority sothat acceptability of the material can be reconsidered.

3. TESTING

a. The test detailed in Clause 3.1a. and the determination of covering capacity inClause 3.2a. are to be carried out for type approval and at least once for eachproduction run of material supplied for Ministry contracts.

3.1 Thermal Conductivity

a. Thermal conductivity is to be determined in accordance with BS 874 and is notto be greater than the following.

Hot Face Cold Face Thermal ConductivityHot Face° C

Cold Face° C

Thermal ConductivityW/(mK)

200 40 0.062

400 40 0.076

500 40 0.084

600 40 0.094

3.2 Covering Capacity—Determination

a. A sample of dried calcium silicate filling compound is to be mixed with a suitablequantity of fresh water until the consistency is such as to permit satisfactoryapplication to a surface by trowelling. The mixture is to be trowelled into aframe of dimensions not less than 150mm ¢ 150mm ¢ 50mm deep and thesurface levelled with the top of the trough. The frame is to be filled by depositinglayers of prepared compound not more than 15mm thick, each layer beingallowed to dry before the next is applied. The finished sample is to be dried andthe covering capacity, calculated from the weight of powder used, is to beexpressed as square metres per 1000kg of dried filling material when applied25mm thick.

3.3 Test Certificates

a. Results of the test in Clause 3.1a. and the determination of covering capacityin Clause 3.2a. are to be retained for inspection by the Quality AssuranceRepresentative named in the contract.

3.4 Rejection

a. Should the sample selected fail to meet the test requirement given in Clause3.1a. two further samples will be allowed. If either of these further samples failsto meet the test requirement the facts are to be reported to the ApprovingAuthority.
