1.These Directions are established for the preparation of test reports for vulcanized rubber tubes to

be used as part of the technical documents under the declaration of conformity scheme.

2.Type and series of type mentioned in the test report are defined as follows:

(1) Type: vulcanized rubber tubes with the same classification, purpose, structure and main

materials are regarded as the same type; the main type being the one with the smallest nominal

diameter.

(2) Series of type: vulcanized rubber tubes under the same type with nominal diameters other than

the main type.

3. In order to prepare the test reports for vulcanized rubber tubes under the declaration of

conformity,

the applicant should provide the type classification form and samples (10 pieces for each type, and

each piece being at least 150 cm) to the Sixth Division, Bureau of Standard, Metrology and

Inspection (BSMI) for conducting the test.

4.The test of the main type should be conducted on the one with the smallest nominal diameter.

The test of series of the type should be conducted on the one with the greatest nominal diameter.

5.Where the registration scope as listed in the test reports is changed, the applicant shall apply to the

BSMI Sixth Division for amendment to the content of test reports. If the added scope covers

vulcanized rubber tubes of the same type with nominal diameters smaller than the main type, all test

items shall be conducted

6.Test items for the main type and series of type are given as follows:

(1) Where CNS 9620 “Tubing (Extruded Rubber Tubing)” is applicable,

a. the main type (all test items): appearance, dimensions, construction and material, tensile

test, hardness, permanent elongation, ageing test, pressure test, cold-resistance test, flame

test, ozone degradation test, hydraulic test, thermal endurance test, detergent-resistance test,

high temperature edible oil resistance test, edible oil resistance test, edible vinegar resistance

test, liquid soap resistance test and marking.

b. Series of type (key test items): appearance, dimensions and pressure test.

(2) Where CNS 9621 “Liquefied Petroleum Gas Hose” is applicable,

a. the main type (all test items): appearance, dimensions, construction, tensile test of rubber

layer (tensile strength and elongation), pressure test, low temperature test, ozone degradation

test, ageing test, immersion test and marking.

b. Series of type (key test items): appearance, dimensions and pressure test.
