The following information shall be specified in the Purchase Order:

a) Type of junction box, i.e., “Bond Box - 5 Terminal for near shoreenvironment”

b) Applicable Standard Drawing

c) Hazardous area classification (if applicable)

5 Site Conditions

5.1. Temperature and Humidity

Relative Humidity: Minimum 0%

Maximum 100% (Condensing)

Temperature: Minimum 0°C (32°F)

Maximum 55°C (131°F)

Ultraviolet Radiation Hourly mean (Dec) 14 W/m²

Hourly mean (July) 28 W/m²

5.2 Onshore Environment

The normal air-borne dust concentration is 1 mg/M³. During sand stormconditions, dust concentrations may reach 500 mg/M³ and winds may gust to112 km/hr. 95% of all dust particles are less than 20 micrometers, and 50% ofall particles are less than 1.5 micrometers in size. The dust may contain sodium,calcium, magnesium, silicon, and aluminum compounds. During high humidityconditions, these compounds function as electrolytes and can result in severecorrosion. Other pollutants which may be present are: H 2S (1 to 5 ppm),CO (50 to 100 ppm), NOx (1 to 5 ppm), SO 2 (1 to 5 ppm), and hydrocarbons(10 to 50 ppm).

5.3 Near Shore EnvironmentCathodic protection junction boxes which are situated onshore, but withinone kilometer from the shoreline of the Arabian Gulf or the Red Sea shall beconsidered to be located in a near shore environment. Near shore equipment aresubjected to the environmental conditions noted in Section 5.2 plus wind blownsea water spray with accumulation of associated mineral salts on exposedsurfaces.

5.4 Offshore Environment

Offshore equipment is subjected to a severely corrosive environment due to

cyclic wet/dry conditions from wind blown sea water spray and theaccumulation of associated mineral salts on exposed surfaces. Other pollutantswhich may be present are: H 2S (1 to 5 ppm), CO (50 to 100 ppm),

NOx (1 to 5 ppm), SO 2 (1 to 5 ppm), and hydrocarbons (10 to 50 ppm).

After “Type Approval” is received, materials and components used forconstruction of the junction boxes shall not be changed or modified withoutwritten authorization by the SME.

7.2 Certification

Cathodic protection junction box enclosures imported into Saudi Arabia shall becertified, labeled or listed by an approved and recognized testing organization toindicate full compliance with NEMA ICS 6 and NEMA 250 for the applicable

NEMA rating.

Cathodic protection junction box enclosures manufactured in Saudi Arabia fornon-classified areas shall comply with Saudi Aramco standard drawings and theappropriate NEMA standard. However, they are exempt from requiring theabove certification labeling or listing provided the required testing has beencompleted with documentation to confirm performance and quality.

8 Packing and Shipping

The export packing, marking and shipping shall be as specified in the Purchase Order.

Revision Summary16 April 2012 Revised the “Next Planned Update.” Reaffirmed the content of the document, and reissued with

minor revisions as follows:- Revised enclosure material to include type 1050 aluminum with powder coating.- Revised enclosure requirements to align with NEC and allow non-explosion proof enclosures in

Class 1 Div. 2 areas provided there are no current interrupting equipment in the enclosure.- Replaced “RSA” with “SME” to be in line with the new RVL procedures.- Removed the reference to “vendor” - Combined paragraph 6.1.1 and 6.1.2.

10 July 2013 Editorial revision to modify the scope of the specification.
