The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been non-governmental, in liaison with IsO, also take part in the work. IsoO collaborates closely y with the InternationalElectrotechnicalCommission(lEC)onallmattersofelectrotechnicalstandardization. International Standards are drafted in accordance with the rules given in the ISO/lEC Directives, Part 2. adopted by the technical committees are circulated to the member bodies for voting.

For a fitting with seal-retaining components, such as seal-retaining caps or rings, the result of the test. buried and above-ground applications. Principle The impact resistance of a fitting is tested by dropping the fitting on to a rigid surface. After impact, the fitting is inspected for any cracks visible without magnification. In the case of fittings with separate fixing elements, of watertightness. NOTE It is assumed that the following test parameters are set by the referring standard a) test temperature (see Clause 3); b) sampling procedure and frequency (see Clause 4); c) conditioning time and temperature, as applicable (see Clause 5) (p the height from which the test piece is to be dropped (see Clause 6); (e the point of impact that is to hit the test base when dropped (see Clause 6); f) test conditions for assessment of watertightness (see Clauses 6 and 7). 3 Apparatus 3.1 Refrigerator or liquid bath, capable of maintaining the conditioning temperature within ±2 °C 3.2 Temperature-controlled environment, capable
