Match the fabric code to measurable requirements and test evidence.

A useful PVC tarpaulin specification sheet needs more than GSM. List the fabric and coating, weight, thickness, usable width, roll length, strength, weather tests and agreed tolerances. Add a unit and test method for each measured value. Before ordering, confirm which values are typical and which are required limits.

01

Identify the fabric

Use one product code, sample reference and document version.

02

Define the checks

Write the units, test methods and conditions beside the numbers.

03

Agree the limits

Set the allowed range and the inspection plan before production.

01 / Know what each document does

TDS, purchase order or test report?

DocumentWhat it doesWhat to check
Technical data sheet (TDS)Describes a named fabric grade and its technical values.Product code, revision and whether values are typical, minimum or another stated type.
Purchase order (PO) + agreed specificationRecords the material, quantity and requirements agreed for the order.Required limits, test methods, approved sample and acceptance rules.
Sample or lot test reportRecords results from the samples that were tested.Sample or roll IDs, date, method, conditions and link to the supplied lot.

What should a PVC tarpaulin TDS include?

Use this checklist to compare suppliers and prepare the specification attached to your PO. Fill in the exact requirements for your project.

FieldWhat to writeUnit, method or check
1. Product identitySupplier, product code, TDS date/revision and approved sample ID.Use the same references on the PO and test report.
2. ConstructionBase fabric, yarn and weave; coated or laminated construction; coating on each face.State yarn units and fabric density units if specified.
3. Total fabric GSMTarget mass per area and allowed lower/upper limits.g/m²; total finished fabric, not coating alone. Example method: ISO 2286-2.
4. ThicknessMeasured thickness and agreed limits.mm; state method and measuring pressure, for example ISO 2286-3.
5. Roll dimensionsTotal width, usable width, roll length, quantity and any allowed joins.m or mm; define edge exclusions. ISO 2286-1 covers roll measurements.
6. StrengthTensile and tear requirements in warp and weft directions.Force unit, specimen details and test method. Compare like-for-like results.
7. Coating adhesionRequired adhesion of coating to the base fabric.Unit and test details; for example ISO 2411. State which face is tested.
8. Outdoor performanceUV/weathering, heat and cold requirements for the use.Method, exposure conditions and result or retained performance required.
9. Water and special needsWater resistance; fire, mildew or chemical tests when needed.Exact method, conditions, result and report scope. Check seams separately.
10. Finish and colorColor reference, gloss/matte finish, lacquer or other agreed treatment.Approved sample and any agreed color/finish acceptance checks.
11. Delivery checksSampling plan, roll/lot labels, core, packing and response to out-of-range results.State whether limits apply to samples, rolls or a lot.

Test-method references describe how to measure. They do not set one universal commercial tolerance or prove that every fabric has passed a test. For a fair comparison, also record the sample conditioning, test temperature and humidity, and whether samples were tested wet or conditioned.

03 / Make the allowed range clear

What tolerances should buyers ask for?

Ask for a target and clear limits for GSM, width and roll length. There is no single percentage that fits every order. Agree the range your cutting plan, equipment and performance needs can accept, plus how it will be measured.

ItemWrite this in the orderWhy it matters
GSMTarget [ ] g/m²; minimum [ ]; maximum [ ]; sampling and acceptance basis [ ].Clarifies allowed variation. A batch average is not an individual-roll limit.
Usable widthMinimum cuttable width [ ]; edge exclusions [ ]; maximum width if your equipment needs it [ ].Total width and usable width may differ.
Roll lengthTarget [ ] m; lower/upper limits [ ]; joins and unusable sections allowed [ ].Makes the usable quantity and any short-roll handling clear.
ThicknessTarget [ ] mm; limits [ ]; method and measuring pressure [ ].Pressure and measurement conditions affect the reading.
Calculation example only

If an order agrees 650 g/m² ±5%:

650 × 5% = 32.5 g/m²
Allowed range: 617.5–682.5 g/m²

This is an arithmetic example, not a Uni-Tarp supply tolerance or an industry default. Confirm the actual limits for your order.

Add these 4 details beside the limits

  1. Method: standard and edition, units and equipment conditions.
  2. Sampling: where samples are taken and how many checks are made.
  3. Acceptance: whether the limit applies to each result, a roll average or a defined lot.
  4. Action: how an out-of-range result is checked and resolved.

For example, two equal-area rolls at 600 and 700 g/m² have an average of 650 g/m². That does not mean either roll meets the example range above. Write the acceptance basis before comparing results.

04 / Match the real conditions

What PVC tarpaulin specification suits long-term outdoor use?

Start with the climate and the way the cover will be used, then select the fabric grade. Specify UV/weathering performance, heat and cold needs, tensile and tear strength, coating adhesion and water resistance. GSM alone cannot set an outdoor service life.

Send these 6 project details

  1. Country or installation location
  2. Expected sun, rain and moisture exposure
  3. Highest surface and lowest handling temperatures
  4. Cover size, supports, seams and fixings
  5. Wind, folding and cleaning conditions
  6. Required replacement interval and any special standards
ConditionWhat to requestWhat to compare
Strong sun / UVWeathering method, cycle, exposure time and results.Color change, cracking and retained strength or other agreed properties.
Heat and freezingHeat ageing and cold-bend requirements for the actual grade.Test conditions and pass criteria. A cold-bend test is not a full service-temperature guarantee.
Rain and standing waterWater test pressure, duration and criteria; separate seam checks.Fabric result, welded joint performance and cover drainage.
Wind and repeated handlingWarp/weft tensile and tear data, adhesion and relevant seam/fixing checks.Material results together with the finished cover and support design.

Color and strength are different: A lightfastness rating describes color performance. If strength after weathering matters, ask for retained tensile or tear results too.

Use our outdoor durability guide for climate selection. Laboratory weathering helps compare materials; there is no simple test-hours-to-outdoor-years conversion. ASTM G151 explains this limitation.

05 / Before approving the order

6 common specification mistakes to avoid

Numbers without context

  • Writing only “650 GSM” with no agreed range.
  • Treating a typical TDS value as a minimum.
  • Comparing strength values with different methods or directions.

Missing delivery details

  • Using total width when your cutting plan needs usable width.
  • Asking for “UV resistant” without test conditions or results.
  • Approving a sample without matching its code to the order and TDS revision.

Before production: confirm the sample, specification revision, required limits and inspection plan in writing. Keep the agreed file with the PO so repeat orders use the same reference.

Quick answers

PVC tarpaulin specification sheet FAQ

What should I specify for long-term outdoor use?

State the location, sun and rain exposure, temperature needs, cover size and handling conditions. Then agree the exact grade, strength, weathering, water and seam requirements. Use test evidence for that fabric, not GSM alone.

What are the key fields on a PVC tarpaulin technical data sheet?

Product code and revision; base fabric and coating; GSM and thickness; roll dimensions; color and finish; tensile, tear and adhesion data; and the weather, water or special tests needed for the use. Include units, methods, value types and agreed limits.

What tolerances should I request for GSM, width and roll length?

Request a stated minimum and maximum, or a clearly defined one-sided limit where appropriate. Agree the range, measurement method and sampling basis with the supplier. Specify usable width and any allowed joins or unusable roll sections.

Can I use the supplier TDS as my purchase specification?

Use it as a starting point. Confirm the product code, revision, required limits and acceptance checks for your order. A typical value is not automatically a minimum. Attach the agreed specification to your PO.

Is the downloadable template a Uni-Tarp product TDS?

No. It is a blank buyer worksheet to help define your requirements. Request a current product TDS for the exact Uni-Tarp fabric you want to order.
