Gas Spring Standards

Standards

There are no National or International Standards for gas springs.

CE Marking & Pressure Equipment Directive (PED) 2014/68/EU

Gas springs and hydraulic dampers manufactured by Camloc Motion Control Ltd can be charged to high internal pressures. They must not be heated or opened. They are manufactured and distributed in accordance with the Pressure Equipment Directive 2014/68/EU(1). Camloc gas springs and hydraulic dampers filled with gas can be used safely as defined by this directive.

Camloc gas springs and hydraulic dampers stay below the limit values in article 4 (1) a) i) of the directive for pressure and volume. Thus, they meet article 4 (3) of the Pressure Equipment Directive 2014/68/EU and are designed and manufactured in accordance with the sound engineering practice of the Member State in which they are produced.

The fluids in their construction are fluids of group 2 according to the classification in article 13 of the directive.

Camloc gas springs and hydraulic dampers are characterised according to article 4 (3) by means of which the manufacturer can be determined and warnings which refer to the possible high internal pressure and resulting dangers. As such Camloc gas springs and hydraulic dampers shall not bear the CE marking referred to in article 18 of the directive.

Camloc gas springs and hydraulic dampers do not fall under the machinery guidelines 98/37/EG or 2006/42/EG.

It is the sole responsibility of the customer or user to verify whether Camloc gas springs and hydraulic dampers used in the end-product meet National or International Laws and Guidelines.

RoHS and WEEE Directives

All Camloc gas springs are compliant with RoHS (Restriction of Hazardous Substances) and WEEE (Waste Electrical & Electronic Equipment) directives. Statements to this effect can be supplied upon request.

REACH Regulation

Products made by Camloc Motion Control Ltd are considered Articles under REACH (Registration, Evaluation, Authority and Restriction of Chemicals) Regulations. Camloc Gas Springs do not contain, or do not exceed the legislative thresholds of any of the Substances of Very High Concern (SVHC’s). Statements to this effect can be supplied upon request.

ELV Directive

The End of Life Vehicle (ELV) directive restricts the use of specific hazardous substances (Lead, Cadmium, Mercury and Hexavalent Chromium). Only Lead, used as an alloying element, is present within Camloc gas springs and falls below the maximum allowable level of 0.1%.

MSDS

Material Safety Data Sheets (MSDS) vary by product type and are available to download from this website.

Gas Spring Life

In ideal fitting circumstances, at room temperature and a maximum of three cycles per minute Camloc Gas Springs have a permitted maximum force loss of 10% after 50,000 cycles. In some instances, our customers have successfully tested Camloc Gas Springs to over 200,000 cycles.

However, it should be noted that in real-life applications the life expectancy of a gas spring is extremely difficult to predict and can vary considerably due to a number of factors.

These factors include the type of environment the spring is to be used in, for how long and in what manner the spring has been stored prior to use, whether the spring is subject to temperature change or temperature cycling, whether the application is subject to vibration, the usage frequency, the type of end fittings used and whether the spring is subject to lateral movement to name a few examples.

Shelf Life and Storage Recommendations

Camloc Gas springs should be stored in a clean, dry environment at room temperature between 10 and 25°C. Springs must be stored with the rod facing downwards.

Some force loss should be expected due to sealing material aging and gas permeability through the seal, typically this would be around 1 to 2% per year and would be typical for all makes of gas spring.

Failure to store the springs in the correct orientation can lead to the seal drying-out which will accelerate force loss.

Factors such as temperature changes and environmental conditions can affect seal aging and speed up the process of force loss.

Most applications will tolerate a maximum force loss of 10%, although this is application dependant.

Warranty Information

Our standard warranty is limited to a maximum of 12-months from the date of shipment.
