2. REQUIREMENTS
2.1 Composition, Appearance and Colour
The profile shall be fabricated from a stabilised modified polyolefin and shall be radiation cross-
linked. It shall be homogeneous and essentially free from defects, pinholes, bubbles, cracks,
inclusions and flaws. The profile shall be coated with a hot melt adhesive on the inner surfaces.
The standard colour shall be black with an amber adhesive.
2.2 Dimensions
Dimensions shall be as per the appropriate Specification Control Drawing (SCD)
2.3 Test Requirements
The test requirements shall be as specified in Table 1.
3. TEST METHODS
3.1
Preparation of Test Specimens
Unless otherwise specified, tests shall be carried out on specimens recovered by conditioning in
a fan assisted air circulating oven at 200 ± 5°C for 4 ± 1 minutes and allowed to cool in air to
ambient temperature. No pre-conditioning period is required prior to testing. Unless otherwise
specified, all tests shall be made under standard ambient conditions according to IEC
Publication 60212. In cases of dispute the tests shall be carried out at a temperature of 23 ± 2°C
and at 50 ± 5% relative humidity.
3.2 Dimensions and Longitudinal Change
Three specimens each approximately 150mm in length shall be measured for each of the
dimensions specified in the relevant SCD. The specimens shall be recovered as specified in
Clause 3.1 and the dimensions re-measured. The longitudinal change shall be expressed as a
percentage of the original length.
3.3 Tensile Strength and Ultimate Elongation
The test method shall be as specified in ISO 37 and shall be carried out on uncoated, but beamed
product only. For sizes below NR.8, whole sections shall be used, but for sizes NR.8 and above,
Type 2 dumb-bells shall be prepared.

TEST METHODS continued
3.4 Adhesion
Five test specimens prepared as described in RTM 2560 shall be pulled on a suitable tensile test
machine. The average value of peel force shall be calculated and reported in N/25mm.
3.5 Split Resistance
Examine the product for evidence of splitting.
4. RELATED STANDARDS & issue
ASTM D882-02 Standard Test Methods for Tensile Properties of Thin Plastic Sheeting
IEC 60212: 1971 Standard Conditions for Use Prior to and During Testing of Solid
Electrical Insulating Materials
ISO 37: 1994 Rubber, vulcanized or thermoplastic - Determination of Tensile Stress-
Strain Properties
RTM 2560 Peel Strength Measurement
Subsequent amendments to, or revisions of, any of the above publications apply to this
standard only when incorporated in it by updating or revision.
5. SAMPLING
Qualification tests are those performed on profile samples submitted for qualification as a
satisfactory product and when a change of formulation takes place, and shall consist of all tests
listed within this specification. Qualification test samples shall consist of 15 metres of profile.
Qualification of any size shall qualify all sizes.
Production Routine tests shall be carried out as follows: every batch; Dimensions, Longitudinal
Change and Split Resistance. When adhesive compound batch changes adhesion will be tested.
Tests shall be carried out on a sample length taken at random from a batch of finished product.
A batch is defined as that quantity of the same size from the same production run and offered for
inspection at the same time.
6. PACKAGING
Packaging shall be in accordance with good commercial practice. Each package shall bear an
identification label showing material quantity, description, size, colour and batch number.
